iphone - UIImageview 在 iOS7 中没有动画，但在 iOS6 中运行良好

Question

revealImgView.animationImages =[NSArray arrayWithObjects:[UIImage imageNamed:@"reveal1.png"],[UIImage imageNamed:@"reveal2.png"],[UIImage imageNamed:@"reveal3.png"],[UIImage imageNamed:@"reveal4.png"],[UIImage imageNamed:@"reveal5.png"],nil];
revealImgView.animationDuration=1.5;
revealImgView.animationRepeatCount=INFINITY;
[revealImgView startAnimating];

这在 iOS 6 中运行良好但在 iOS 7 中不起作用。我已经在 nib 中制作了 UIImageView

Answer 1

它应该可以工作，如果在一段时间后没有调用该方法，

        double delayInSeconds = 0.5;
        dispatch_time_t popTime = dispatch_time(DISPATCH_TIME_NOW, delayInSeconds * NSEC_PER_SEC);
        dispatch_after(popTime, dispatch_get_main_queue(), ^(void){
            [self getAllImgViewAnimating];
        });


    -(void)getAllImgViewAnimating
    {
    revealImgView.animationImages =[NSArray arrayWithObjects:[UIImage imageNamed:@"reveal1.png"],[UIImage imageNamed:@"reveal2.png"],[UIImage imageNamed:@"reveal3.png"],[UIImage imageNamed:@"reveal4.png"],[UIImage imageNamed:@"reveal5.png"],nil];
    revealImgView.animationDuration=1.5;
    revealImgView.animationRepeatCount=INFINITY;
    [revealImgView startAnimating];
    }
