冻结动画的最后一帧？

Question

有没有办法在我的iphone应用程序中冻结动画的最后一帧？到目前为止，这是我的代码。

popup.animationImages = [NSArray arrayWithObjects:
                                 [UIImage imageNamed:@"picture1.png"],
                                 [UIImage imageNamed:@"picture2.png"],
                                 [UIImage imageNamed:@"picture3.png"],
                                 [UIImage imageNamed:@"picture4.png"],
                                 [UIImage imageNamed:@"picture5.png"],
                                 [UIImage imageNamed:@"picture6.png"],
                                 [UIImage imageNamed:@"picture7.png"], nil];
        popup.animationDuration = 1.750567;
        popup.animationRepeatCount = 1;
        [popup startAnimating];
        [self.view addSubview:popup];

当动画停止时，UIImageView会在其image属性中显示UIImage设置。所以你应该将它设置为动画的最后一帧：

popup.image =  [UIImage imageNamed:@"picture7.png"];
