图片轮流显示

UIImageView内置的动画功能

原理：轮流显示一组图片

#import "ViewController.h"

@implementation ViewController

- (void)viewDidLoad
{
    [super viewDidLoad];
    
    NSMutableArray *array = [[NSMutableArray alloc]initWithCapacity:0];
    for (int i = 1; i <= 10; i++) {
        UIImage *img = [UIImage imageNamed:[NSString stringWithFormat:@"%d.png",i]];
        [array addObject:img];
    }
    
    UIImageView *imgView = [[UIImageView alloc]initWithFrame:CGRectMake(0, 0, 320, 460)];
    [self.view addSubview:imgView];
    [imgView release];
    imgView.animationImages = array;//图片数组
    imgView.animationDuration = 1.75;//所有图片播放一次的总时间
    imgView.animationRepeatCount = 0;//重复播放次数
    [imgView startAnimating];//开始播放
}
