回答1:

Please check below conditional code for iOS 8.x and iOS 7

if (SYSTEM_VERSION_GREATER_THAN_OR_EQUAL_TO(@"8.0")) 
{
    modalController.preferredContentSize = CGSizeMake(frameSize.x, frameSize.y); 
}
else 
{
    modalController.view.superview.frame = CGRectMake((screenWidth - frameSize.x)/2, (screenHeight - frameSize.y)/2, frameSize.x, frameSize.y);

}

Hope this will help you.
