播放gif动画

// 设定位置和大小 
CGRect frame = CGRectMake(50,50,0,0); 
frame.size = [UIImage imageNamed:@"anim.gif"].size;
// 读取gif图片数据 
NSData *gif = [NSData dataWithContentsOfFile: 
    [[NSBundle mainBundle] pathForResource:@"anim" ofType:@"gif"]];
// view生成 
UIWebView *view = [[UIWebView alloc] initWithFrame:frame]; 
[view loadData:gif MIMEType:@"image/gif" textEncodingName:nil baseURL:nil];

发生错误原因：线程内未调用Looper.prepare()，不能创建处理器。
解决办法：在线程Check的run()中加入 Looper.prepare();

public void run() {
	// TODO Auto-generated method stub
	super.run();
	Looper.prepare();
	setting = new Preference(context);
	check();
	}
