iOS8 animation code does not work anymore - objective-c

Question

The code I used to animate a UITextField worked for me until XCode Version 6.0 (6A215l). Now XCode6 Beta7 not reposition UITextField. What should I do to make it work?
Here the code:
#interface TableConfigViewController ()
#property(nonatomic, strong) IBOutlet UITextField *customTableName;
#end
- (void)viewDidLoad
{
[super viewDidLoad];
[self.customTableName setDelegate:self];
}
- (void)animateTextField:(UITextField*)textField
up:(BOOL)up
{
const float movementDuration = 0.5f;
const int movementDistance = 380;
int movement = (up ? -movementDistance : movementDistance);
[UIView beginAnimations: #"animation" context:nil];
[UIView setAnimationDelegate:self];
[UIView setAnimationBeginsFromCurrentState:YES];
[UIView setAnimationDuration:movementDuration];
self.customTableName.frame = CGRectOffset(self.customTableName.frame, 0, movement);
[UIView commitAnimations];
}
- (void)textFieldDidBeginEditing:(UITextField*)textField
{
[self animateTextField:textField up:YES];
}
- (void)textFieldDidEndEditing:(UITextField*)textField
{
[self animateTextField:textField up:NO];
}
Thank you very much in advance

Not sure if this is the source of your problem but you should consider using the block based APIs (available since iOS 4.0) for UIView animations.
From Apple's docs regarding beginAnimations:context:
"Use of this method is discouraged in iOS 4.0 and later. You should use the block-based animation methods to specify your animations instead."
For example (untested):
- (void)animateTextField:(UITextField*)textField
up:(BOOL)up
{
const float movementDuration = 0.5f;
const int movementDistance = 380;
int movement = (up ? -movementDistance : movementDistance);
[UIView animateWithDuration:movementDuration
animations:
^{
self.customTableName.frame = CGRectOffset(self.customTableName.frame, 0, movement);
}
];
}
