Hi Readers,

In our app we usually make custom alerts which we need to animate at the time adding it on its superview.

To achieve it with you custom view make a category like this :

Put this code into your .h file of category named as UIView+AnimateView :

@interface UIView (AnimateView)

- (void)addSubviewWithBounce:(UIView*)subview;

- (void)removeSubviewWithAnimation:(UIView*)subview;

@end

After that use following code in your .m file:

@implementation UIView (AnimateView)

- (void)addSubviewWithBounce:(UIView*)subview
{
    subview.transform = CGAffineTransformScale(CGAffineTransformIdentity, 0.001, 0.001);

    [self addSubview:subview];

  [UIView animateWithDuration:0.3/1.5 animations:^{
    CGAffineTransformScale(CGAffineTransformIdentity, 1.1, 1.1);
} completion:^(BOOL finished) {
    [UIView animateWithDuration:0.3/2 animations:^{
        subview.transform = CGAffineTransformScale(CGAffineTransformIdentity, 0.9, 0.9);
    } completion:^(BOOL finished) {
        [UIView animateWithDuration:0.3/2 animations:^{
            subview.transform = CGAffineTransformIdentity;
        }];
    }];
}];
}

- (void)removeSubviewWithAnimation:(UIView*)subview{

    subview.transform = CGAffineTransformIdentity;

    [UIView animateWithDuration:0.3/1.5 animations:^{
        subview.transform =  CGAffineTransformScale(CGAffineTransformIdentity, 0.001, 0.001);
    } completion:^(BOOL finished) {
        [subview removeFromSuperview];
    }];
}

@end

Just import this category on any controller and call these function like :

[self.view removeSubviewWithAnimation:subview];
[self.view addSubviewWithBounce:subview];

Thanks. Happy coding
