[iPhone] Question on simple animated view transitions

Hello All,
I am trying to learn how view transitions work and I am having a very hard time with the sample apps (like transition view app etc)...I need something much more simple at first. Can you please provide me a little guidelines on how to set up this following scenario:
App loads up and shows a title screen with a button that says go. When you click on the go button the title screen fades out and a new view fades in (or slides in, or anything at all).
Right now I have 3 nib files. There is the main one that is called on application start (tied with MainViewController, a subclass of IUViewcontroller just like in the hello world app. After the app loads the app delegate object tells the MainViewController object to load in another view controller object (via addSubview) which is tied with the second nib file; my title screen with the button. So far this works fine; when I press the button I was thinking in the IBAction function to tell the MainViewController object to remove (or transition out somehow) the title screen view controller object then add the other view (third nib file in). This is the part I can't get working. Am I on the right track or have a gone hideously astray? Thank you!

Would you mind linking to the thread you're referring to? That would help.

I am trying to create a simple animated gif in Photoshop. I've set up my frames and want to use the tween to make the transitions less jerky. When I tween between frame 1 and frame 2 the object in frame two goes out of position, appearing in a different place than where it is on frame 2. Confused!

Hi Melissa - thanks for your interest. Here's the first frame, the second frame and the tween frame. I don't understand why the tween is changing the position of the object in frame 2, was expecting it to just fade from one frame to the next.

hi,
i managed to do this for my app. (think i referred to viewTransitions sample code and modified quite a bit)
i can't remember this well cos i did this quite a while back, but i will try to help as much as possible
1) from the appdelegate i initialize a root controller (view controller class)
2) this root controller actually contains two other view controllers, let's call it viewAController and viewBController, for the screens which u are going to toggle in between. and there's also a function, let's call it toggleMenu, which will set the menus to and fro. i copied this whole chunk from the sample code. it actually defines the code on what to do, i.e. if current view is A switch to B and vice versa.
3) inside the controller files, you need to implement the toggleMenu function too, which basically calls the rootController's toggleMenu
4) we also need viewA and viewB files(view class)
5) need to add the .xib files for the respective views and link them up to the controller class. i did not use the .xib files for ui layout though, because of my app's needs. however, it will not work properly without the .xib files.
5) inside the view class of both views, i.e. viewA.m and viewB.m, you need to create a button, that will call the toggleMenu function inside the respective controller class.
it will look something like this:
[Button addTarget:ViewAController action:@selector(toggleMenu:) forControlEvents:UIControlEventTouchUpInside];
so the flow is really button (in view)-> toggleMenu(viewController) -> toggleMenu(rootController)
i'm sorry it sounds pretty hazy, i did this part weeks before and can't really remember. i hope it helps.

HT4753 I have a very simple question: how do I view where Lion has autosaved my current version to (without the convoluted route of using finder)? In days gone by i'd simply use the save as function to see where it was being saved.

I have a very simple question: how do I view where Lion has autosaved my current version to (without the convoluted route of using finder)? In days gone by i'd simply use the save as function to see where it was being saved.

It's actually even easier than using Save As to see the full path to the currently open document. Just do a "Secondary click" on the document title in its window's title bar.
Like you, I relied upon Save As my whole life to check a file's location and considered it a must-have capability. Turns out it's even faster to use the single-click method to reveal the full path to the open document. It displays the entire path to the current document starting from the level of your Mac, and works for files stored on drives as well as iCloud.
If you're not sure how to do a secondary click, go into System Preferences, select Trackpad, Point & Click to find the current preference for secondary click on your Mac. If you happen to have a mouse with more than one button, it's probably the right button. As a trackpad user, I check the box to "Click or tap with two fingers," so a simple two finger tap on the title of an open document reveals its full path. This feature actually has been around for a very long time.
Note that this is not the same thing as the Autosave and Versions menu, which is exposed using a little drop down triangle to the right of the title. There is no visual clue for the presence of this feature - you just have to know it's there, probably because this feature goes all the way back to pre-OS X days.

Can there be more than one icloud account on a computer? I have an icloud account with my iphone but would like to view my photo stream on my husbands mac. I do not have a mac but an older PC. thanks

Welcome to the Apple community.
The simple answer is yes you can. On a single user computer, the user can have secondary iCloud accounts, which they can add through the system preferences > mail, contacts and calendars. The only drawback here is that only the primary iCloud account can use photo stream. This can be worked around by having a second user account on the Mac. Each user account could then have a different primary iCloud account, one for you and one for him, your account could then receive your photo stream pictures.
Are you also aware that you can have iCloud on your PC and download your photos stream pictures to it.

Simple Font Viewer

Hello everyone
This may be a dump question, but does anyone know a simple font viewer? When I was using KDE I just needed to click on a font file and I could see what the font looked like. Now I switched to xfce (with Thunar as file manager) and there is no such programme. I do not seek a fancy font management tool or something like that. I am sure I just need to pick the right Gnome package, just: which one is it?
Thank you very much in advance!

HELP MAKING VERY SIMPLE ANIMATION - Adobe Flash CS5

- First off, apologies for the simplicity of the task I need to carry out- cannot seem to find any tutorials on this. (All aimed at After Effects)
- I am hoping to make two simple animations;
1. Animate the word "water" so it appears to be moving like water itself.
2. Animate the word "sand" so it appears to crumble into sand itself.
Appreciate any help, very new to Flash - still no luck after Lynda and other tutorials.

Not exactly the answer to your question but found a tutorial page that could help you.

View transitions with NavigationBar

Can any one show me or point me in the direction of some sample code on how to make custom transitions i.e fade in/out etc when using a UINavigationBar i know how to make the custom transition through apple "view transitions" sample code but do not know how to implement this with a navigation bar setup.
Any help would be great.
Thanks

Hi John, and welcome to the Dev Forum!
To use you own animation between navigation views, all you need to do is turn off the nav controller's animation and add your own just as you would do if there were no nav controller.
Here's an example in which I pasted performTransition from the ViewTransitions sample app into the Navigation-based app template:
// * from Navigation-Based app template
#import "RootViewController.h"
#import "AnotherViewController.h"
#import <QuartzCore/QuartzCore.h>
@implementation RootViewController
// from viewTransitions sample app
-(void)performTransition {
// First create a CATransition object to describe the transition
CATransition *transition = [CATransition animation];
// Animate over 3/4 of a second
transition.duration = 0.75;
// using the ease in/out timing function
transition.timingFunction = [CAMediaTimingFunction functionWithName:kCAMediaTimingFunctionEaseInEaseOut];
// Now to set the type of transition. Since we need to choose at random, we'll setup a couple of arrays to help us.
// * we don't want a random type
// NSString *types[4] = {kCATransitionMoveIn, kCATransitionPush, kCATransitionReveal, kCATransitionFade};
// NSString *subtypes[4] = {kCATransitionFromLeft, kCATransitionFromRight, kCATransitionFromTop, kCATransitionFromBottom};
// int rnd = random() % 4;
// transition.type = types[rnd];
transition.type = kCATransitionFade;
// * we don't want a random subtype
// if(rnd < 3) // if we didn't pick the fade transition, then we need to set a subtype too
// transition.subtype = subtypes[random() % 4];
// * no subtype is needed for kCATransitionFade
// transition.subtype = kCATransitionFromTop;
// * code to lock out multiple taps is probably unnecessary - see if this method ever repeats during the transition
NSLog(@"performTransition");
// Finally, to avoid overlapping transitions we assign ourselves as the delegate for the animation and wait for the
// -animationDidStop:finished: message. When it comes in, we will flag that we are no longer transitioning.
// transitioning = YES;
// transition.delegate = self;
// Next add it to the containerView's layer. This will perform the transition based on how we change its contents.
// [containerView.layer addAnimation:transition forKey:nil];
// * the containerView in this case is the navController's view
[self.navigationController.view.layer addAnimation:transition forKey:nil];
// Here we hide view1, and show view2, which will cause Core Animation to animate view1 away and view2 in.
// * the nav controller will do the actual view switch
// view1.hidden = YES;
// view2.hidden = NO;
// * from Navigation-Based app template
// Override to support row selection in the table view.
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath {
// Navigation logic may go here -- for example, create and push another view controller.
AnotherViewController *anotherViewController = [[AnotherViewController alloc]
initWithNibName:@"AnotherViewController" bundle:nil];
UITableViewCell *selectedCell = [tableView cellForRowAtIndexPath:indexPath];
anotherViewController.title = selectedCell.textLabel.text;
[self performTransition];
[self.navigationController pushViewController:anotherViewController animated:YES];
[anotherViewController release];
The corresponding pop animation is left as an exercise for the student. Hint: It's not so easy to modify what the built-in back button is doing. Consider putting your own back button on the left side of the nav bar.
You can also use UIView animation (including flip and curl) in much the same way. For an example, scroll down to switchTopController in this thread: [http://discussions.apple.com/thread.jspa?messageID=10524660&#10524660]. The game in that example was to have 3 screens that all popped back to the screen which had transitioned to the first of them. So instead of calling popViewController, we make a new, rearranged stack so the screen switch happens when the current stack is replaced by the new one. That replacement isn't animated, so the UIView animation works as expected.
Hope that helps!

IPhone question: Im trying to update applications on my iphone. When I do it I'm as for password from a different Apple ID from what I have in Itunes. How do I change so that both are the same?

IPhone question: Im trying to update applications on my iphone. When I do it I'm as for password from a different Apple ID from what I have in Itunes. How do I change so that both are the same?

All apps are tied to the apple id that it was used to purchase or download the app.
did you use a different id to buy the app?
you can change id, settings - appstore - apple id - log out and log in with correct id.

I have the latest version of free Quicktime, Itunes and unable to view video on my PC all i get is a pink screen the audio is OK i have uninstalled and installed several times same problem, i have a Iphone 4 and unable to view the content.

Open your QuickTime control panel (either via the Control panels, or by going "Edit > Preferences > QuickTime Preferences" in the Quicktime Player). In the Advanced tab, uncheck Enable Direct3D video acceleration:
... and click OK. Quit and restart the QuickTime Player prior to checking to see if the settings change has had any effect.

Help need in a simple animation

Hello !
I hope somebody can help me, i want to make a simple animation to my logo in macromedia flash 8.
The resource picture is in jpg (but i think i have in png also if that is better) and there is a text next to the logo.The background is black. I want to animate the text line,like its appering from the black.It is as if a cover was drawn before it along.The rest of the picture is fixed.
How can i do that ?
Thank You !

sorry im absolutely new to flash so i dont know how to do that.
here is the picture http://sherto.deviantart.com/art/Iris-Soft-193301609
so its like this : at the first frame, there are no text and with 3-4 frames the " I " comes in and etc... the rest.
as you can see there is a picture close to the texts so i cant cover them with a rectangle tool as big as the text,because it would go into the picture when moves.
once again im sorry im new so i cant even move the rectangle above the pic.
do you have any simple idea for this ?
anyway thank you for the anwser !

Convert simple animation code from as2 to as3

Hi everyone,
I have a simple animation that is controlled by the y movement of the mouse. The code for the animation is put in frame 1 and is as follows:
var animationDirection:Boolean = false;
var prevMousePosition:Boolean = false;
var mouseListener = new Object();
mouseListener.onMouseMove = function () {
var curMousePosition = _ymouse;
if(curMousePosition > prevMousePosition) {
animationDirection = false;
}else if(curMousePosition < prevMousePosition) {
animationDirection = true;
prevMousePosition = curMousePosition;
Mouse.addListener(mouseListener);
function onEnterFrame() {
if(animationDirection && _currentframe < _totalframes) {
nextFrame();
}else if(!animationDirection && _currentframe > 1) {
prevFrame();
Is it possible to use this code in as3 or do I need to convert it? I am grateful for any help. Best wishes

Yes, you need to convert the code. Here is what looks like a similar logic in AS3:
import flash.events.Event;
import flash.events.MouseEvent;
var animationDirection:Boolean = false;
var prevMousePosition:Boolean = false;
addEventListener(Event.ENTER_FRAME, onEnterFrame);
addEventListener(MouseEvent.MOUSE_MOVE, onMouseMove);
function onMouseMove(e:MouseEvent):void {
    var curMousePosition = mouseX;
    if (curMousePosition > prevMousePosition)
        animationDirection = false;
    else if (curMousePosition < prevMousePosition)
        animationDirection = true;
    prevMousePosition = curMousePosition;
function onEnterFrame(e:Event):void
    if (animationDirection && _currentframe < _totalframes)
        nextFrame();
    else if (!animationDirection && _currentframe > 1)
        prevFrame();

How to make simple animation of 2D object ?

I am a beginner of LABVIEW, and here is my problem...
For each time loop, I can get a the x,y,theta information of a rigid body in the 2D plane.
I want to use those data to make a simple animation to represent how the object is moving like in a 2D plane, which includes the 2DOF translation movement and 1DOF rotation movement.
How should I do?
Thanks a lot for helping me!

You can use XY graph to plot the trajectory of the object.
Regarding the introduction of the XY graph, you can refer to the tutorial on LabVIEW pro.
http://www.labviewpro.net/teach_content.php?fid=6&post=308&fpt=5
This can only represent the XY movement, not include the rotation part.
I don't think there's any graph control in LabVIEW that can represent the rotation aspect.

Simple animation software for Arch?

Can anyone suggest a simple animation program for Linux; something similar to AnimationShop for windows. I know there's gimp-GAP, but that seems to be fairly advanced for my purposes. I just want to be able to string together images into .gif or video, perhaps with an 'onion layer' feature so you can see the previous frame transparently; that sort of thing.
I use gnome, so preferably something for GTK, or at least if it's KDE, that depends only on QT and not KDE packages.
Any ideas?
Thanks.

skottish wrote:You don't actually need GAP to do animated Gifs in Gimp. All you need to do is add all the frames that you want as layers in one image, then save as Gif. Gimp will ask you if you want to flatten the image or make an animation out of it. If you choose animation, it will ask you for a frame rate.
Thanks. I realised this eventually and got it done that way.
Still, out of curiosity are there any 'film-strip' type animation programs out there?
