我试图在ios中做一个动画，我复制了一个工作示例（对我来说很有用）但是我编辑它有一个更长的动画：按下按钮开始动画，它显示第一个图像，但从未进展通过其余的。
请参阅下面的代码！
#import "ViewController.h"
#import <QuartzCore/QuartzCore.h>
@interface ViewController ()
@end
@implementation ViewController
@synthesize imageView;
- (void)viewDidLoad
{
[super viewDidLoad];
// Do any additional setup after loading the view, typically from a nib.
UIImage *image = [UIImage imageNamed:@"invasive0001.png"];
self.imageView =[[UIImageView alloc] initWithFrame:CGRectMake(22, 110, 724, 451)];
[self.view insertSubview : self.imageView atIndex:0];
self.imageView.layer.cornerRadius = 9.0;
imageView.layer.masksToBounds = YES;
imageView.layer.borderColor = [UIColor blackColor].CGColor;
imageView.layer.borderWidth = 3.0;
self.imageView.animationImages = [[NSArray alloc] initWithObjects: [UIImage imageNamed:@"invasive0001.png"],

全部谢谢！
* * 更新：我尝试在设备上运行它，但是当我按下播放按钮时崩溃，它在模拟器上工作正常，这可能是因为图像太多了吗？
再次感谢。

另一个问题是您指定的帧速率超过每秒700帧，帧数为287帧，持续时间为0.4。尝试不设置self.imageView.animationDuration，允许UIImageView计算一个默认值，该值将产生每秒30帧的动画。我个人总是把它保留为默认值，只有在我想要更低的帧速率（更长的动画）时才更改它。

尝试加载如下图像文件。你可能需要摆弄循环和前导零。
NSMutableArray *array = [NSMutableArray array];
for (int i=2; i < 288; i++) {
NSString *name = [NSString stringWithFormat:@"invasive%04d.png", i];
UIImage *image = [UIImage imageNamed:name];
if (!image) {
NSLog(@"Could not load: %@", name);
}
else {
[array addObject:image];
}
}
self.imageView.animationImages = array;
