引入NSURLConnectionDelegate委托

	NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:[NSURL URLWithString:stringUrl] cachePolicy:NSURLRequestReloadIgnoringLocalAndRemoteCacheData timeoutInterval:3];
	[NSURLConnection connectionWithRequest:request delegate:self];

NSURLRequestReloadIgnoringLocalAndRemoteCacheData决定使用缓存的方式

常用委托

- (NSURLRequest *)connection:(NSURLConnection *)connection willSendRequest:(NSURLRequest *)request redirectResponse:(NSURLResponse *)response;
- (void)connection:(NSURLConnection *)connection didReceiveResponse:(NSURLResponse *)response;

- (void)connection:(NSURLConnection *)connection didReceiveData:(NSData *)data;

- (void)connectionDidFinishLoading:(NSURLConnection *)connection;
