Question

我在线教程中找到了这段代码。它以无限循环播放动画。

我想制作一个播放三次然后结束的动画。现在我有一个循环动画。这是一个非常简单的问题，但因为我是iOS的新手。

#import "APOViewController.h"

@interface APOViewController ()

@end

@implementation APOViewController

- (void)viewDidLoad
{
    [super viewDidLoad];
    // Do any additional setup after loading the view, typically from a nib.
    NSArray *imageNames = @[@"win_1.png", @"win_2.png", @"win_3.png", @"win_4.png",
                            @"win_5.png", @"win_6.png", @"win_7.png", @"win_8.png",
                            @"win_9.png", @"win_10.png", @"win_11.png", @"win_12.png",
                            @"win_13.png", @"win_14.png", @"win_15.png", @"win_16.png"];

    NSMutableArray *images = [[NSMutableArray alloc] init];
    for (int i = 0; i < imageNames.count; i++) {
        [images addObject:[UIImage imageNamed:[imageNames objectAtIndex:i]]];
    }

    // Normal Animation
    UIImageView *animationImageView = [[UIImageView alloc] initWithFrame:CGRectMake(120, 80, 86, 193)];
    animationImageView.animationImages = images;
    animationImageView.animationDuration = 0.5;

    [self.view addSubview:animationImageView];
    [animationImageView startAnimating];

}

- (void)didReceiveMemoryWarning
{
    [super didReceiveMemoryWarning];
    // Dispose of any resources that can be recreated.


}

@end

感谢。我试图将迄今为止收到的两个不同的答案结合起来。但我仍然收到一个错误“'UIImageView'没有可见的@interface'声明了选择器'animationRepeatCount：'

以下是我将代码更改为：

#import "APOViewController.h"
#import "UIKit/UIImageView.h"

@interface APOViewController ()
@property(nonatomic) NSInteger animationRepeatCount;

@end

@implementation APOViewController

- (void)viewDidLoad
{
    [super viewDidLoad];
    // Do any additional setup after loading the view, typically from a nib.
    NSArray *imageNames = @[@"win_1.png", @"win_2.png", @"win_3.png", @"win_4.png",
                            @"win_5.png", @"win_6.png", @"win_7.png", @"win_8.png",
                            @"win_9.png", @"win_10.png", @"win_11.png", @"win_12.png",
                            @"win_13.png", @"win_14.png", @"win_15.png", @"win_16.png"];

    NSMutableArray *images = [[NSMutableArray alloc] init];
    for (int i = 0; i < imageNames.count; i++) {
        [images addObject:[UIImage imageNamed:[imageNames objectAtIndex:i]]];
    }

    // Normal Animation
    UIImageView *animationImageView = [[UIImageView alloc] initWithFrame:CGRectMake(120, 80, 86, 193)];
    animationImageView.animationImages = images;
    animationImageView.animationDuration = 0.5;

    [self.view addSubview:animationImageView];

    [animationImageView startAnimating];
    [animationImageView animationRepeatCount:3];
    [animationImageView stopAnimating];

}

- (void)didReceiveMemoryWarning
{
    [super didReceiveMemoryWarning];
    // Dispose of any resources that can be recreated.


}

@end

Answer 1

这样做：

[animationImageView setRepeatCount:3];

Answer 2

使用UIImageView的属性@property（非原子）NSInteger animationRepeatCount;

iOS：如何让动画播放3次然后结束？
