Pinch/Flick Gesture Events in iPhone SDK

just a simple question to the iPhone SDK.
is there a simple possibility to read a pinch or flick gesture without programming and interpreting a multitouch sequence myself?
Im looking for methods i can simply override like OnPinch or OnFlick.
Ive searched for quite a while and cant find anything like this although im sure it must be available.

There is no built in function to read a pinch or a flick. You have to implement it yourself using:
- (void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event;
- (void)touchesEnded:(NSSet *)touches withEvent:(UIEvent *)event;
Depending what you want to do it may require some math to accomplish what you want to do. I had to dig into some old school books to make it work.

    Hi,
    I have had this happen to me during the special iMac event last summer and currently with the iPhone SDK event. I get the error message:

  • Using Flick Gesture on Web (Photo) Application

    Hi everyone, my company developed a Web application that displays photo albums, my problem was, is it possible to use the Flick gesture on an external controller or scroller (e.g. virtual keyboard-like, but instead, a scroller) to browse the photos? Similar to "Cover Flow" feature on iPod... the flicking area is not on the browser, instead, on a virtual scroller or something, is it posible?
    thanks in advance!

    Anantonix,
    He is referring to the gesture used to flip through photos that are stored on the iPhone, and if that can be used on a web page.
    I am not certain one way or another, but you might be able to find that out on this link:
    https://developer.apple.com/iphone/devcenter/designingcontent.html
    In addition it has links under each of the collapsable menu options, including some links to Web development mailing lists.
    Hope this helps,

  • IPhone SDK - What is the equivalent of a combo box

    I have a screen where there are quite a few items which are of the multiple-choice type. In other platforms i use a combo box (pick lists) to do this.
    On the iPhone SDK the only thing that comes close is the UIPicketView which is ugly IMHO. it takes too much real estate and too heavy.
    Is this is the only control available now?
    Also does the UIPicker come with an associated control which will launch the picker? What i mean is on other platforms and on the web there is a text field with a button with a down arrow next to it. Clicking either on the text field or the down arrow drops the list down. Is there a similar control on the iPhone which when clicked launches the picker OR do i have to create a button or a custom view which will launch the picker?
    Thanks for reading this and for your feedback.

    I do not believe there is an equivalent of -D in the DB JVM, a possible solution is:
    Load a properties file into the DB using Loadjava, then open this file from your Java code using Properties.load(), then iterate the properties calling System.setProperty().

    They're not lost, they simply don't show because you settings ask it not to.

  • Learning iPhone SDK - Trying to draw an image

    Although I have programmed for Mac in the last years, I have never used Mac-specific technologies as Cocoa (I have programmed more in OpenGL, SDL, and the like).
    Now I am getting started with the iPhone SDK. I'd like to do some OpenGL|ES stuff, but since it is not supported in the Simulator, and you need to join the Developer Program to test stuff on directly on the device (and admission of new members is closed right now), I am focused on other stuff right now, like using Core Graphics for drawing images on the iPhone.
    My application is based on the Cocoa Touch Application template. I left the default code except for a few changes.
    In file "UntitledAppDelegate.m", I have changed the method applicationDidFinishLaunching to:
    - (void)applicationDidFinishLaunching:(UIApplication *)application {
    window = [[[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]] autorelease];
    contentView = [[[MyView alloc] initWithFrame:[[UIScreen mainScreen] applicationFrame]] autorelease];
    [window addSubview:contentView];
    [window makeKeyAndVisible];
    Then, in the MyView interface file (MyView.h), I have added the attribute "UIImageView* image;" to the class, which is declared as a property, and synthesized.
    In the class implementation (MyView.m), I have changed the method initWithFrame to:
    - (id)initWithFrame:(CGRect)frame {
    if (self = [super initWithFrame:frame]) {
    self.backgroundColor = [UIColor darkGrayColor];
    image = [self loadImageView:@"box01.png"];
    [self addSubview:image];
    return self;
    loadImageView is a private method I have implemented as:
    - (UIImageView *)loadImageView:(NSString *) imageName {
    UIImage *img = [UIImage imageNamed:imageName];
    UIImageView *theView = [[UIImageView alloc] initWithImage:img];
    return theView;
    Since I have loaded the UIImage, and initialized a UIImageView with it, and the image view is added as a subview of the main view attached to the window, I thought it should be everything needed to draw an image on the screen. But nothing is visible. The screen is simply black when I run this on the Simulator. It doesn't even set the background to dark gray.
    So I need some help with this, I sure that anyone with experience in Mac programming will know how to help me.
    Thank you in advance.

    I removed the XIB file from the project, but that didn't help. It was a problem with my inexperience with Objective-C. When accessing class properties in a method of the same class, i was not putting "self." before the property (in C++ that's redundant). For example, in the line "window = [[[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]] autorelease];". After adding it, it works correctly.

  • How do I delete an event on iPhone calendar with no edit icon

    How do I delete an event on iPhone when no edit icon appears

    Have you tried to open the event and delete it? Tap on the event to open it, then scroll down to delete it.
    You can also try toggling iCloud syncing for the calendar on and off (or off and on), this sometimes makes hte edit button reappear.

  • IPhone SDK CodeSign Error: Redux (latest OS X update is broken)

    This bug - http://discussions.apple.com/thread.jspa?threadID=1455699&start=0&tstart=0 - is back. My AdHoc project, which worked perfectly last week, has just stopped building, with this:
    "object file format invalid or unsuitable"
    As soon as I upgraded from 10.5.7 to 10.5.8, this bug appeared.
    However, this bug was officially fixed in 10.5.7 - so, I'm guessing here, Apple has accidentally re-created it.
    Unfortunately, I cannot add to the original post, because Apple has frozen the topic.
    So, here's a new topic to ask if anyone else is having this problem, and what they did about it - is it exactly the same as the old bug? or is it different in some way?
    I'm going to try some of the workarounds for the old bug - but hacking command line scripts isn't fun, and I'm worried I might break something even worse .

  • IPhone SDK 2.2 memory corruption

    Hello. I'm working on an application for iPhone SDK 2.2 and seem to be having weird memory corruption problems. Not necessarily leaks because using Instruments shows my memory stamp never going above about 1.8 megs. The nature of the app is a database of animals so I'm constantly loading and unloading sounds and images. None of the objects are very large (at most I'll have 4 800k pngs loaded at once) and I've checked and rechecked my alloc/retain/release and everything is in order (hence no memory usage increase). However...after using the application for a while I'll notice strange behavior. For example:
    1) we have a UILabel as the title for each page. After a while the font size of this will change.
    2) I have several screens with a subclassed UIScrollView where images are loaded and then added to. The problem shows itself here by the images not showing up. there's no crash, stepping through the debugger shows that the image loads up fine, it's just that the image is not there.
    3) I have a UILabel at the top of an animal description screen, which in the nib file is called "Animal Name" by default. This will change to show "Animal Name" at the top.
    I've removed all audio in our latest build so that isn't the problem. What I'm starting to suspect is that altering anything defined in a nib file will cause corruption. For example, the UIScrollView is defined in the nib file, and I constantly am reassigning the contents of that with a UIImageView. This UIImageView is handled within the subview class like :
    UIImageView *imgView = [[UIImageView alloc] initWithImage: [ UIImage imageWithContentsOfFile:[[NSBundle mainBundle ] pathForResource:imageToLoad ofType:@"png" ]] ];
    imgView.tag = 50;
    [self addSubview:imgView ];
    [ imgView release ];
    Then later when moving away from the screen I'll find that view's tag and remove it from the superview (since addSubView increases the retain count, the alloc+addSubView is cancelled by release+removeFromSuperView)
    I can't explain why titles that are never changed would be affected, but it must somehow be related. What I'm wondering is: are there any known issues involving modification of the contents of objects defined in Nib files? Perhaps the memory allocated when initWithNibName is restrained, then any modification of objects allocated within it can cause corruption. I'm starting to think I should just alloc and free anything modified in code and skip using nib files altogether (I reset the text on buttons for example). If this is a known issue please let me know. I'll give you more information if I can.
    Thank you

    Just download the huge SDK package and install. No need to uninstall the old SDK.

  • Problem in set selectedTextcolor in uitableview cell in iPhone SDK 3.1.2

    Hello,
    I set selected text color in uitableview cell using cell.selectedTextColor = [UIColor whiteColor]; for iPhone SDK 2.2.1.
    Now i use iPhone SDK 3.1.2, So for that i make change as per documentation for that i use textLabel properties. But selectedTextColor is not exit.
    So Now for SDK 3.1.2 how to set selectedTextColor?..
    Thank you.

    The textLabel property is an instance of UILabel, so it has its own textColor, textAlignment, and font properties. E.g.:
    cell.textLabel.text = @"foo";
    cell.textLabel.textColor = [UIColor whiteColor];
    cell.textLabel.textAlignment = UITextAlignmentLeft;
    Hope that helps!

  • IPhone SDK : Communication between iPhone client and a remote server

    Hi,
    This is w.r.t iPhone Cocoa Touch native application.
    i need to populate my application 's data from a remote application server ( which in turn connects to the database) . I require some tips in the communication between client sitting on the iPhone and the remote application server. I am planning to proceed in XML transaction way.
    I referred the SeismicXML sample application provided by Apple. In this sample,client reads the physically existing xml file from @"http://earthquake.usgs.gov/eqcenter/catalogs/eqs7day-M2.5.xml"; and the client parses the xml file and display the content on the table view.
    i have following 2 queries ,
    1. I do not want to read from a physically present file,i want the data to be transferred on the go.
    Means, request should be sent from the client to a application server and the server process returns the data in form of xml file ( but its not creating any physical xml file) .
    Basically i am looking for request - response concept.
    2. Can we call a java process(which returns xml data) running on a remote server from the cocoa touch client.? If not java process,what would be other best way...
    i am going through the Apple provided frameworks. Do any of the iPhone SDK frameworks support this request? If some one has any idea on the above mentioned queries, pls help me.
    any pointers will also be helpful.
    It might be too early to talk about these,but i have to take some business decision related on this.
    thanks in advance.

    You already know how to send a string via HTTP Post? And you know how to make XML into a string? Put the two together.
