Automatically center a UIImageView after rotation

[bnabilos]

Hello

I have an UIImage inside an UIImageView in my application.

In portrait mode, the image is centered but when I switch to the landscape mode it stills on the left.

So I added the following method in my .m file but the problem is that I have a TabBar application, so when I rotate the device on another tab and I go back to the tab containing the image, it doesn't rotate automatically.

There is a way to rotate automatically all the elements of the application when rotating the device on any tab ?

-(void)didRotateFromInterfaceOrientation:(UIInterfaceOrientation)fromInterfaceOrientation {
    if((self.interfaceOrientation == UIDeviceOrientationLandscapeLeft) || (self.interfaceOrientation == UIDeviceOrientationLandscapeRight)){
        background.image = [UIImage imageNamed:@"back2-landscape.png"];
    } else  if((self.interfaceOrientation == UIDeviceOrientationPortrait) || (self.interfaceOrientation == UIDeviceOrientationPortraitUpsideDown)){
        background.image = [UIImage imageNamed:@"back2-portrait.png"];
    }
}

Thank you :-)

You don't need any code. Adjust the resizing masks in IB according to the behavior that you want.

Thank you for your answer but I don't know exactly what I have to do

I have an image that I want to place in my view, its size is 280x50px, I center it in portrait mode but when I rotate the device it stills in the same position, I want it to be centered automatically

Which resizing masks should I adjust?

Select your image view. Go to the inspector (Cmd-3). Play with the red lines until the animation reflects your desired behavior.
