首先说说异步方式下的获取
#pragma mark NSURLConnection Delegate Methods
- (void)connection:(NSURLConnection*)connection didReceiveResponse:(NSURLResponse*)response {
NSHTTPURLResponse* httpResponse = (NSHTTPURLResponse*)response;
int responseStatusCode = [httpResponse statusCode];
}
再来说说同步方式下的获取
NSHTTPURLResponse* urlResponse = nil; NSError *error = [[NSError alloc] init]; responseData = [NSURLConnection sendSynchronousRequest:request returningResponse:&urlResponse error:&error]; int statusCode = [urlResponse statusCode]; int errorCode = error.code;
