Answer 1

我注意到您正在执行同步请求。如果请求花费很长时间，您的应用很可能会强制退出。

请改用异步请求。

[NSURLConnection connectionWithRequest:request delegate:self]; 

并实现委托方法：

-(void) connection:(NSURLConnection *)connection didReceiveResponse:(NSURLResponse *)response; 
-(void) connection:(NSURLConnection *)connection didReceiveData:(NSData *)data; 
-(void) connectionDidFinishLoading:(NSURLConnection *)connection;
