This is just some UI elements that can be added through code

I have got my own custom UIViewController, which contains a UIScrollView with an UIImageView as it's subview. I would like to make the image to auto rotate when device orientation changes, but it doesn't seem to be working...

In the header file, I've got;

@interface MyViewController : UIViewController {
IBOutlet UIScrollView *containerView;
UIImageView *imageView;
}
These components are initialised in the loadView function as below;

containerView = [[UIScrollView alloc] initWithFrame:frame];

NSData *data = [NSData dataWithContentsOfURL:[NSURL URLWithString:@"http://..."]];
UIImage *image = [[UIImage alloc] initWithData:data];
imageView = [[UIImageView alloc] initWithImage:image];
[image release];

[containerView addSubview:imageView];
And I have added the following method, assuming that's all I need to make the view auto-rotate...

-(BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation {
return YES;
}
MyViewController loads fine with the image I've specified to grab from the URL, and the shouldAutorotate... function is being called, with the correct UIInterfaceOrientation, when I flip the device too.

However, didRotateFromInterfaceOrientation method do not get called, and the image doesn't seem to rotate itself... Could someone please point out what I need to add, or what I have done wrong here?


UILABLE ROTATE :

/*************************
As August said, I'm not sure of your use case on this, but there's a reasonably straightforward way to do it using Core Animation. First, you'll need to add the QuartzCore framework to your project and do a

#import
somewhere in your headers.

Then, you can apply a rotational transform to your UILabel's underlying layer using the following:

yourLabel.layer.transform = CATransform3DMakeRotation(M_PI, 0.0f, 1.0f, 0.0f);
which will rotate the label's CALayer by 180 degrees (pi radians) about the Y axis, producing the mirror effect you're looking for.

I faced the same situation. It is suggested that you change the height of your view when the keyboard appears. The problem in the case you've described is, there is not enough content in the tableview to scroll up and still have something in the area hidden by the keyboard.

If you adjust the size of the tableview to be equal to 480-150 (height of view - height of keyboard), and use scrollToRowAtIndexPath, it will work as expected. Once the keyboard hides again, change back the height of the tableview to the original height.

These are the UIView parameters that can be animated:
frame
bounds
center
transform
alpha


[UIView beginAnimations:nil context:NULL];
[UIView setAnimationDuration:kTransitionDuration];
[UIView setAnimationTransition:UIViewAnimationTransitionFlipFromRight forView:self.view cache:YES];

//If you need to position anything and not have it animated add it before the beginAnimations block

[UIView beginAnimations:nil context:nil];
[UIView setAnimationDuration:0.6]; //The time in seconds the animation should last.

// In Interface Builder I set the tag of the first button to 1 and the second to 2.
// You could create seperate functions for both bottoms but in this case it's not needed.

if ([sender tag] == 1){
[view1 removeFromSuperview];
[window addSubview:view2];

I think the only thing you're looking for is:

UIView's

+ (void)setAnimationTransition:(UIViewAnimationTransition)transition forView:(UIView *)view cache:(BOOL)cache;
and

UIViewAnimationTransitionFlipFromLeft,
UIViewAnimationTransitionFlipFromRight,
These animation transitions can only be used within an animation block. The transition is set on the container view and then the old view is swapped out for the new view, then the animation is committed.

Like:

CGContextRef context = UIGraphicsGetCurrentContext();

[UIView beginAnimations:nil context:context];
[UIView setAnimationTransition:UIViewAnimationTransitionFlipFromLeft forView:yourContainerView cache:YES];
[yourContainerView exchangeSubviewsAtIndex:0 withSubviewAtIndex:1];
[UIView commitAnimations];

CodeSign error: a valid provisioning profile is required for product type ‘Application’ in SDK ‘Device - iPhone OS 2.2″
This error will appear when you update your provisioning profile in iPhone SDK 2.2
or after the expiration of developer certificate and that you have a new provisioning profile from the developer portal
This is the solution (which is modified from http://www.furmanek.net/54/iphone-sdk-22-codesign-error/)
Suppose you have copied your provisioning profile called “iPhone_Development.mobileprovision” to the Library folder and build & go an old iPhone project called “MyApp”, and this annoying error appears
(1) cd ~/Library/MobileDevice/Provisioning\ Profiles/
(2) find out the UUID of the provisioning profile
strings iPhone_Development.mobileprovision | grep ".*-.*"
output is like this
xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx
(3) copy that UUID between the string tag
(4) close xcode and go to your project
cd ~/Projects/MyApp/MyApp.xcodeproj
(5) Use a text editor to open the project.pbxproj
find the string PROVISIONING_PROFILE
paste the UUID that you copied from step (3) and put it in both Debug and Release Sections (do multiple finds) for the following line
e.g.
PROVISIONING_PROFILE = "xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx";
(6) Launch XCode and open the project and build & go again




This seems to be a chronic issue and is unresolved across many forums. This error occurs when you Build and Go for Device - iPhone OS 2.1 and can be verified when looking under Project Info > Build > Code Signing > Code Signing Provisioning Profile > Any iPhone Device, the name of your Provisioning Profile (ie. ITP DAP Projects) will not be listed as a Value.
I was able to resolve this issue by restoring my iPhone in Xcode under the Summary tab of the Organizer window.
Before doing so, you should of course confirm you have the Development Certificate and WWDR Intermediate Certificate in place, and have the Provisioning Profile both on your Mac under Library > MobileDevice > Provisioning Profile and on your iPhone under Settings > General > Profile
