我想在iPhone的子视图中显示gif图像。示例代码glgif在控制器的根视图上显示gif图像,但是当我进行以下修改时,应用程序崩溃了:
IBOutlet UIView *gifView; // gifView is added as a subview of controller's root view
//PlayerView *plView = (PlayerView *)self.view;
PlayerView *plView = (PlayerView *)gifView;
// Load test.gif VideoSource
NSString *str = [[NSBundle mainBundle] pathForResource:@"test" ofType:@"gif"];
FILE *fp = fopen([str UTF8String], "r");
VideoSource *src = VideoSource_init(fp, VIDEOSOURCE_FILE);
src->writeable = false;
// Init video using VideoSource
Video *vid = [[GifVideo alloc] initWithSource:src inContext:[plView context]];
VideoSource_release(src);
// Start if loaded
if (vid) {
[plView startAnimation:vid];
[vid release];
return;
}
// Cleanup if failed
fclose(fp);
Video *vid = [[GifVideo alloc] initWithSource:src inContext:[plView context]];
出现错误消息:
-[UIView context]: unrecognized selector sent to instance
. 关于如何正确地将plView添加到子视图中有什么想法吗?
