UIView动画不适用于文本，开始在iPhone App中进行编辑

Question

I am making the iPad app in which I want to show animation when I start click on beginEditing here is the my code.

-(void)textFieldDidBeginEditing:(UITextField *)textField
{
    NSLog(@"This is calling");
    [self showAnimationPests];
}

-(void) showAnimationPests
{
    [UIView animateWithDuration:0.5
                     animations:^{
                         subView.frame = CGRectMake(0,-200,1024,748);

                     }];
}

It shows Log this is calling but view does not move.

Answer 1

If it's an iphone app why is the size of it 1024x748 ?

CGRectMake takes points not pixels (if you are trying to make up for retina display). And those points for iPhone 5 are 320x568 and previous devices 320x480 .

Answer 2

try with my bellow code

Example..

- (BOOL)textFieldShouldBeginEditing:(UITextField *)textField {

    [UIView beginAnimations:nil context:NULL];
    [UIView setAnimationDuration:0.3];
    subView.frame = CGRectMake(0,-200,1024,748);
    [UIView commitAnimations];
    return YES;
}

and set to 0 like default in textFieldShouldReturn: method like bellow..

- (BOOL)textFieldShouldReturn:(UITextField *)textField {
        [UIView beginAnimations:nil context:NULL];
        [UIView setAnimationDuration:0.3];
        subView.frame = CGRectMake(0,0,1024,748);
        [UIView commitAnimations];
        return YES;
}
