-(Void) textFieldDidBeginEditing :( UITextField *) textField

{// This method is called when you click inside textField to start editing. TextField will become first responder

If (textField. tag = 2 ){

NSTimeInterval animationDuration = 0.30f;

CGRect frame = self. view. frame;

Frame. origin. y-= 216;

Frame. size. size + = 216;

Self. view. frame = frame;

[UIViewbeginAnimations: @ "ResizeView" context: nil];

[UIView setAnimationDuration: animationDuration];

Self. view. frame = frame;

[UIViewcommitAnimations];

}

}

 

-(BOOL) textFieldShouldReturn :( UITextField *) textField

{// When the user presses ruturn and removes the focus from textField, the keyboard disappears.

// TextField

If (textField. tag = 2 ){

NSTimeInterval animationDuration = 0.30f;

CGRect frame = self. view. frame;

Frame. origins. y + = 216;

Frame. size. height = 216;

Self. view. frame = frame;

// Self. view

[UIViewbeginAnimations: @ "ResizeView" context: nil];

[UIView setAnimationDuration: animationDuration];
