Creating buttons on the fly and setting button properties

If I have a view and want to add buttons to it "on the fly" from values in an array, is that something straightforward to do?
I have an array of UIImageVIew objects and would like to create buttons from them (showing the image on the buttons) and associate those buttons with a method in my implementation file. That would be a lot more general and flexible than creating the buttons in the Interface Builder I would imagine.
And one more question - can I freely set button properties while doing that? Or in Objective-C can I only set properties that are already pre-defined for that class?
Thanks!

Thanks for your reply.
That.... works! Thanks!
And I can generate the button and click on it and it calls my other method and that works too. Cool!
The syntax is still very mysterious to me, but I suppose eventually I'll understand what it all means.
Breaking it down to see what it means:
[button1 addTarget:self action:@selector(selectedHandler1:) forControlEvents:UIControlEventTouchUpInside];
* button1 is the object I created (I'm going to try to do this in a loop next.)
* addTarget is a message I am sending to button1 and the content of the message is "self", which refers to - this button? I'm not sure why such a message would be necessary.
* action is another message sent to button1 and the contents of that message are a little harder to parse. I see the result, and can mimic the syntax now that I've seen it, but I don't really understand what the @ is for, or the : after the method name or why this wouldn't just be "action: selectedHandler". I'm sure the language designers have a logical reason for all that, but I don't quite "grok" those extra symbols yet.
* forControlEvents is another message sent to button1 and the event message itself is clear in its meaning.
Anyway, that is working and I can refer more to the UIButton class reference now and try to set more stuff, like position it better, etc.
Thanks very much!

  • How to hide the Print and Export button in analytics report or tasks pane

    Hi Experts,
    In BIEE 11g,
    How to hide the Print and Export button in analytics report or tasks pane ?
    For example:
    In console,I have created one userA which is belong to BIConsumer GROUP , when I make use of the highest user 'weblogic' to create one simple report, then the userA will login the analytivs to view this report (not dashboard), it will show the print and export as below.So customers do not want to give him the privilege for printing and exporting.
    In addtion, go to catalog->tasks(left corner), it will also show the print and export button. So how to hide or not access these button?
    Note: Maybe it can use the policy for consumer role for implementing this requirement, but I do not know how to modify the policy. Are you facing the problem? Thanks.

    Hi,
    1. Create seperate folder for Reports & Dashobard.
    2. For BI_Consumer (userA) set the catalog permission to view Dashboard Folder only and remove permission on the Report Folder (you can give traverse permission but don't give Open permision).
    3. By this user won't be able to open or run any reports in that folder and the only way he can see the reports is through Dashboard and on dashboard the export and print buttone can be removed very easily.
    Mark helpful if it helps.

  • HT1175 I am trying to setup my Time capsule via a ethernet cable as a back up for a new iMac. The on button on the time capsule set up window keeps failing to stay on. Any ideas what to do?

    I am trying to setup my Time capsule via a ethernet cable as a back up for a new iMac. The on button on the time capsule set up window keeps failing to stay on. Any ideas what to do?

    A PC can have more issues connecting than a Mac.
    But it really should not matter.. so just try it in situ.. press and hold the reset.. once it starts up, it will return to default IP, 10.0.1.1 the PC should then be able to find it via the airport utility.
    If not drag it over to the Mac and plug in there by ethernet.. or since it is a laptop, really should not be that difficult to drag the Laptop and plug it into the TC.
    Important thing is to get access to the TC.
    The Mac if it is running lion, then you MUST download and install 5.6 airport utility to do anything useful.

  • How to delete help button in the wizard and dialogs.

    Hello,
    I am trying to delete the Help button in the wizard and dialogs provided by bibeans and having problems. Can someone give me an advise regarding the following three issues please? Thank you.
    bibeans:bibeans903a
    JDeveloper:JDeveloper903
    1)Deleting the Help Button from the Print Dialog.
    I'm using "oracle.dss.dataView.gui.PrintDialog" for the Print Dialog and this class has method to delete the Help button(setHelpEnabled(Boolean)).
    But, the Help button is always displayed even when I set false for this method like below.
    PrintDialog.setHelpEnabled(false);
    2) Deleting the Help button from Open Dialog and BI Explorer.
    I am using "PersistenceObjectChooser" class for Open Dialog and "Explorer" class for BI Explorer. But, these classes does not have a method to delete the Help button like the PringDialog class has. How can I delete the Help button for these dialogs?
    3) Deleting the Help button from Calculation Builder.
    I am using "CalcBuilderStepStorage" class to build a calculation and trying to delete the Help button like this.
    ((DefultBuilderDialog)calcBuilderStepStorage.getContainer()).getWizard().setHelpAvailable(false);
    But, again the Help button will be displayed

  • In Firefox 3.6.10 I was able to go forward and backwards between pages without the page defaulting to the top of the page. Is there any way to prevent the page from automatically moving to the top when using the forwards and back buttons in Firefox Four?

    I like to be able to navigate backwards and forwards without having to scroll down and find where I was previously. In Firefox Four, when using the forwards and back buttons, the page will automatically return to the top of the page. Is there any way to change this setting in Firefox Four to prevent it from doing that?

    Thanks for the response. No Time Machine, but I probably have a backup from a few months ago on an external hard drive. :/ I guess it'd have useful history, but not if it overwrote the last 3 months or so of Awesome Bar, that might not be so great.

    The Find my iPhone service option is given to you when you first set up the device. If you just reset it, you may have been given that option. So, in other words, the service may have been enabled even if you didn't realize it. You can then go to www.icloud.com and click on Find my iPhone, and have it play a sound. Or, you can use the Find my iPhone app on your mom's iPhone, but the service would still need to be turned on on your iPod.
    Unlike Compukid said, Apple will not assist in locating a lost device without the Find my iPhone service.
    I found that out 2 years ago, it's just that I thought Apple might have changed that.

  • How do I get all the control buttons in one place in 3.6.16, like they used to be in previous versions? Having the refresh and stop buttons between address and search windows, and the home button to the far right is awful.

    In 3.6.16, the buttons are all over the place. In previous versions, the forward, back, refresh, stop and home buttons were all together. In this version, the refresh and stop buttons are between the address and search windows, and the home button to the far right.
    I would love to have them all together as they used to be - much more user friendly that way. I have tried installing alternate themes, but the coding of this version over-rides the themes.

    * Move the Reload and Stop buttons to their previous position at the left side of the location bar.
    * Set the order to "Reload - Stop" to get a combined "Reload/Stop" button.
    * Set the order to "Stop - Reload" or separate them otherwise to get two distinct buttons.

  • Why is the "Delete" and "Junk" buttons repleased with the "Archive" button (Only for one of the accounts)?

    Hello,
    I must have changed a setting, so that the "Delete" and "Junk" buttons above the mail pane have disappeared, and an "Archive" button has appeared instead. This is true only for my mail through Gmail (IMAP), but when i open a mail from my other account (POP), i still see the "Delete" and "Junk" buttons.
    How can I fix this?
    Thanks in advance
    Ayse

    Try this:
    Select an email that does not show all the correct buttons in the header information section above the actual message.
    right click on the blank area just above 'Other Actions', you should get a popup saying 'Customise'.
    click on 'Customise'
    a new window opens.
    you can drag items onto that header area, but I would suggest you click on 'Restore Default Set' button and then clickon 'Done' button.

  • When I upgraded to FF4, the "refresh" and "MSN" button disappeared. Where are they, how do I get them back?

    The "refresh" button and the button for my homepage appeared on the line just under the Menu Bar. Also, the MSN icon appeared on the fourth line under the Menu Bar. All three are now missing How do I get them back, or do I have to uninstall FF4. Why does an upgrade have to change toolbars without giving me notice?

    You can find the Home button at the far right end of the Navigation Toolbar.
    Firefox 4 uses a combined Stop/Reload/Go button that is positioned at the right end of the location bar.<br />
    During the page load process it shows as a Stop button and after the loading has finished the button is changed to a Reload button.<br />
    If you type in the location bar then that button becomes a Go button.<br />
    You can middle-click that Reload button to duplicate the current tab to a new tab.
    To move the Stop and Reload buttons to their position to the left of the location bar you can use these steps:
    * Open the "View > Toolbars > Customize" window to move the Stop and Reload button out of the location bar.
    * Drag the Reload and Stop buttons to their previous position to the left of the location bar.
    * Set the order to "Reload - Stop" to get a combined "Reload/Stop" button.

  • If you hold down the up and down buttons....

    hi. Am i being really stupid but if you hold the up or down buttons on a macbook pro keyboard it doesnt scroll up and down the page? if you keep pressing the buttons it does or press the fn button together with the up or down arrows it works as it does with the touch pad mouse.
    Just thought that like an a pc laptop the up and down buttons would scroll up and down a page by holding them down which my macbook pro doesn"t.
    Am i right or do i have a faulty keyboard?
    Thanks

    i have figured out the answer. In system preferences the keboard options were set as long/slow. now i have adjusted them to very fast and my kepboard is responsive again. cant believe i was so dumb!
