首先请问一个可能是菜鸟的问题！我对目标C完全陌生！

我想对图像进行动画处理，动画结束时应显示动画“ dymchart20.png”的最后一个图像。我怎样才能做到这一点？

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];

谢谢您的帮助！！！

您可以使用NSTimer并将其声明为aniChartView作为类的属性，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
