首先请原谅我可能是菜鸟问题！我是目标 C 的新手！

我想对图像进行动画处理，并且在动画结束时应该显示动画“dymchart20.png”的最后一张图像。我该怎么做？

这是我的动画代码：

aniChartView.animationImages = [NSArray arrayWithObjects:
                                [UIImage imageNamed:@"dymchart01.png"],
                                [UIImage imageNamed:@"dymchart02.png"],
                                [UIImage imageNamed:@"dymchart03.png"],
                                [UIImage imageNamed:@"dymchart04.png"],
                                [UIImage imageNamed:@"dymchart05.png"],
                                [UIImage imageNamed:@"dymchart06.png"],
                                [UIImage imageNamed:@"dymchart07.png"],
                                [UIImage imageNamed:@"dymchart08.png"],
                                [UIImage imageNamed:@"dymchart09.png"],
                                [UIImage imageNamed:@"dymchart10.png"],
                                [UIImage imageNamed:@"dymchart11.png"],
                                [UIImage imageNamed:@"dymchart12.png"],
                                [UIImage imageNamed:@"dymchart13.png"],
                                [UIImage imageNamed:@"dymchart14.png"],
                                [UIImage imageNamed:@"dymchart15.png"],
                                [UIImage imageNamed:@"dymchart16.png"],
                                [UIImage imageNamed:@"dymchart17.png"],
                                [UIImage imageNamed:@"dymchart18.png"],
                                [UIImage imageNamed:@"dymchart19.png"],
                                [UIImage imageNamed:@"dymchart20.png"],nil];

// all frames will execute in 3 seconds
aniChartView.animationDuration = 0.8;
// repeat the annimation forever
aniChartView.animationRepeatCount = 1;
// start animating
[aniChartView startAnimating];

谢谢你的帮助！！！

您可以使用 NSTimer 并将您的 aniChartView 声明为您的类的属性，如下所示：

@interface ViewController ()

@property (nonatomic, strong) UIImageView *aniChartView;
@end

@implementation ViewController

- (void)viewDidLoad
{
    [super viewDidLoad];
// Do any additional setup after loading the view, typically from a nib.
}

- (void)beginAnimation {
    self.aniChartView.animationImages = [NSArray arrayWithObjects:
                            [UIImage imageNamed:@"dymchart01.png"],
                            [UIImage imageNamed:@"dymchart02.png"],
                            [UIImage imageNamed:@"dymchart03.png"],
                            [UIImage imageNamed:@"dymchart04.png"],
                            [UIImage imageNamed:@"dymchart05.png"],
                            [UIImage imageNamed:@"dymchart06.png"],
                            [UIImage imageNamed:@"dymchart07.png"],
                            [UIImage imageNamed:@"dymchart08.png"],
                            [UIImage imageNamed:@"dymchart09.png"],
                            [UIImage imageNamed:@"dymchart10.png"],
                            [UIImage imageNamed:@"dymchart11.png"],
                            [UIImage imageNamed:@"dymchart12.png"],
                            [UIImage imageNamed:@"dymchart13.png"],
                            [UIImage imageNamed:@"dymchart14.png"],
                            [UIImage imageNamed:@"dymchart15.png"],
                            [UIImage imageNamed:@"dymchart16.png"],
                            [UIImage imageNamed:@"dymchart17.png"],
                            [UIImage imageNamed:@"dymchart18.png"],
                            [UIImage imageNamed:@"dymchart19.png"],
                            [UIImage imageNamed:@"dymchart20.png"],nil];

    // all frames will execute in 3 seconds
    self.aniChartView.animationDuration = 0.8;
    // repeat the annimation forever
    self.aniChartView.animationRepeatCount = 1;
    // start animating
    [self.aniChartView startAnimating];

    [NSTimer scheduledTimerWithTimeInterval:0.8 target:self selector:@selector(staticImage) userInfo:nil repeats:NO];

}

-(void)staticImage {

    [self.aniChartView stopAnimating];
    [self.aniChartView setImage:[UIImage imageNamed:@"dymchart20.png"]];

}

@end

非常感谢SonGoku68！我做到了，它就像一个魅力！

【解决方案2】：

动画不会改变其动画元素的状态。这意味着如果您的 uiview 有背景图像，那么一旦动画停止，该图像将是相同的。同样的事情也适用于动画的颜色变化，或者你动画的任何其他属性。为了实现您的目标，您必须在动画结束后显式调用将 UIImage 更改为您想要看到的那个。 :)
