I encountered the same problem. The solution that worked for me was to set the background of my "MainWindow.xib" to "Clear Color" (default is "White Color").
If you have no xib, you can still set the color in your AppDelegate: [self.window setBackgroundColor:[UIColor clearColor]];
if u need only launcher effect , better try this , light weight library

Hope this Helps!
It seems to me that the method:
- (void)applicationDidFinishLaunching:(UIApplication *)application {
is lacking at the end:
[navigator.window makeKeyAndVisible];
If you need more help, please, post your code...

Using this on iPhone 5:
EGOPhotoViewController *photoController = [[EGOPhotoViewController alloc] initWithImageURLs:imageURLs];
[self.navigationController pushViewController:photoController animated:YES];
When I get back to the caller I can see the bottom bar... How should I solve this?
That doesn't happen on 3.5 inch screen.
UPDATE:
Same problem happens on EGOPhotoViewer_Demo
This is how the screen looks on the first usage:
When getting into "Photos" and go back to that main screen it change to:
You can see something hides the bottom of the screen. On my app I have buttons there so it's problematic.
Hope this update makes my problem more clear.
I’m not sure but this might be a duplicate of iPhone 5 app displaying correctly but not sensing touches in “extra” space
Also, do you have the same problem on iOS 6? From the screenshots, it seems you are using iOS 7, which could be the source of your problem.
When compiling with Xcode 5 the problem is solved (test device was iOS 7).
I had the same issue.
The problem is the following statement in viewWillAppear:
[self.navigationController setToolbarHidden:NO animated:YES];
Move this statement and the accompanying "if" test to viewDidAppear and the problem goes away.
To be honest I am not sure why this ever worked - but it makes sense that showing the toolbar when our photo view is not yet up would show the toolbar in the parent view, not the photo view. Moving it to viewDidAppear does the right thing.
UPDATE: cut/copy/paste disabled in my app.
I am confused with my iOS app while developing for iPhone devices. Execution flow enters a point like the code below
[self navigationController] pushViewController:chooseDeviceView animated:YES];
[chooseDeviceView release];
[numberTextField setText:#""];
The view changes and things "work properly". The problem is that after this the cut/copy/paste functionality is missing in my app.
Don't really know how to start debugging the issue. Does it ring a bell to anybody?
That was a very complicated issue for a beginner. Finally the issue was a little bit related with status message corrupts main window in my iPhone app
Add in your new viewController this:
- (BOOL)canBecomeFirstResponder {
return YES;
}
It should solve your issue.
I have a button that I need to move on viewDidLoad but it doesn't want to move...
strange thing is that if I use the same exact code on a -(IBAction) then it moves as it should... any clue why is this happening?
the code I'm using to move the button is this:
self.myButton.center = CGPointMake(50, 120);
thanks for any help.

For anyone that run in the same problem I found the solution in this tread: presentViewController: crash on iOS <6 (AutoLayout)
removing the "Use Autolayout" option let my app work fine.
I believe that I did everything necessary to change my app for ipad (was for iphone at start). I can toggle the build status to either iphone (only), ipad (only) or iphone/ipad - and the app launches either in ipad or iphone simulator. I can do that forth and back at will.
I added the idiom to check for ipad and basically for one of my xib, instead of using the string of my xib to create the controller, I use the one for the ipad. So it is a new xib for ipad with all same graphical objects ( enlarged ;-) ) . I added the callbacks to function correctly with IB.
I can see everything fine and arrive on my new ipad view BUT when I click on one of my buttons... nothing happened like if my callbacks don't work. It is very surprising and actually I have no idea where to look as I compared most of the parameters between my iphone and ipad view and they are identical as far as I can see.
It must be something damn obvious so if one of you had the same issue and it was a very simple answer ... I guess that would be what I missed!
Thanks for your help in advance

EDIT1: Some code as requested
at start I have that to decide either way:
if (UI_USER_INTERFACE_IDIOM() == UIUserInterfaceIdiomPad)
{
examTFVC_NIB=#"ExamTFViewController-iPad";
}
else
{
examTFVC_NIB=#"ExamTFViewController";
}
Then to go to the right view:
ExamTFViewController *examTFViewController = [[ExamTFViewController alloc]
initWithNibName:globals.examTFVC_NIB bundle:nil];
But I have no problem loading the correct XIB. The issue is really the callback functions not being called...
Thanks for the help.
EDIT2:
I also realised that calling the extension of the xib xxx~ipad allows to avoid the example code above. And it works - but still no function can be called.
EDIT3:
IMPORTANT FINDING: if I move my buttons higher and on the left of the screen: they work! So it seems that the functions are called if the event are in the region of an iphone screen although I am on an ipad screen. I guess know it would be more obvious to find the issue! thanks for any help – geebee just now
ANSWER
iPad touch detected only in 320x480 region
- (void)applicationDidFinishLaunching:(UIApplication *)application {
// to correct region size
CGRect rect = [[UIScreen mainScreen] bounds];
[window setFrame:rect];
// now, display your app
[window addSubview:rootController.view];
[window makeKeyAndVisible];
}
** OR OTHER SOLUTION **
Check the full screen at launch checkbox - only present in the ipad xib MainWindow
finally solved - with 2 methods - programmatically or via IB - in the edited section of the post.
are their any reasons why my UIActionSheet would be taking a while to load. It works fine just after lauch, but as soon as I loop through some actions once or twice, is loads very slow, and you can see the grey backdrop crawl down to finish drawing the sheet.
help?

Ok, so I found the solution moments later.
I assume this is how it works, feel free to correct me.
U used the cheats animation way of [ UIView ]
and i guess this changed the way for the UIActionSheet to pop up, so I wrote in these two lines before i asked it to show.in.view
- (IBAction)goToBlog{
contactUs.actionSheetStyle = UIActionSheetStyleDefault;
[UIActionSheet setAnimationDelay:0];
[UIActionSheet setAnimationDuration:0.1];
[contactUs showInView:self.view];
}
and that seemed to work. so im happy.
