dancer.gif
使用UIWebView播放
- (void)showGifByWebview {
#pragma clang diagnostic ignored "-Wnonnull"
NSString *path = [[NSBundle mainBundle] pathForResource:@"dancer" ofType:@"gif"];
NSData *data = [NSData dataWithContentsOfFile:path];
UIWebView *webview = [[UIWebView alloc] initWithFrame:CGRectMake(60, 90, 100, 75)];
webview.scalesPageToFit = YES;
[webview loadData:data MIMEType:@"image/gif" textEncodingName:nil baseURL:nil];
webview.opaque = NO;
[self.view addSubview:webview];
[self showGifByImageView];
}
将GIF图片分解成多张PNG图片，使用UIImageView播放
- (void)showGifByImageView {
NSURL *gifUrl = [[NSBundle mainBundle] URLForResource:@"dancer" withExtension:@"gif"];
CGImageSourceRef gifSource = CGImageSourceCreateWithURL((CFURLRef)gifUrl, NULL);
size_t imageCount = CGImageSourceGetCount(gifSource);
NSMutableArray *mutableArray = [[NSMutableArray alloc] init];
for (size_t i = 0; i < imageCount; i++) {
//获取源图片
CGImageRef imageRef = CGImageSourceCreateImageAtIndex(gifSource, i, NULL);
UIImage *image = [UIImage imageWithCGImage:imageRef];
[mutableArray addObject:image];
CGImageRelease(imageRef);
}
UIImageView *imageView = [[UIImageView alloc] initWithFrame:CGRectMake(60, 185, 100, 75)];
imageView.animationImages = mutableArray;
imageView.contentMode = UIViewContentModeScaleAspectFit;
imageView.animationDuration = 0.5;
[imageView startAnimating];
[self.view addSubview:imageView];
CFRelease(gifSource);
}
