Question

I have the same animation code applied to various views in my object, so i thought I would standardise it with it’s own class. Here is the code i have:

.h

#import <Foundation/Foundation.h>
#import <UIKit/UIKit.h>

@interface AHAnimations : NSObject

+(void)popInView:(UIView *)view;

@end

.m

#import "AHAnimations.h"

@implementation AHAnimations

+(void)popInView:(UIView *)view {

    view.alpha = 0;
    view.transform = CGAffineTransformMakeScale(0.9, 0.9);
    [UIView animateWithDuration:0.3
                          delay:0
                        options:UIViewAnimationOptionAllowUserInteraction
                     animations:^{
                         view.alpha = 1;
                         view.transform = CGAffineTransformMakeScale(1, 1);
                     }completion:nil];
}

@end

But instead of animating, the view just appears.

Any ideas why this isn’t working?

EDIT: The original code is exactly the same. I can paste it, but other than being a different method name, i’d just be copying and pasting it from above. And now, it is simply [AHAnimations popInView:view];

Answer 1

  UIView *myview=[[UIView alloc] init];
  [myview setFrame:CGRectMake( 50.0f, 50.0f, 280.0f, 400.0f)];
  [UIView commitAnimations]; 
  [UIView beginAnimations:@"animateTableView" context:nil];
  [UIView setAnimationDuration:0.7];
  [myview setFrame:CGRectMake( 5.0f, 70.0f, 310.0f, 350.0f)];

// CALL This line to stop animation

 [myview.layer removeAllAnimations];
 [UIView commitAnimations];
