NSURLConnection 遵守代理协议但是不能响应代理

郁闷了一个下午,中午解决了这个问题,在单独的demo里,自己封装的方法用的很好,但是放到工程中就是不行

解决方法就是为这个线程开启一个runloop使它始终处于运行状态，需要定一个全局的BOOL类型的finished变量来进行控制。代码如下：

-(void)getPostRequestWithInterface:(NSString *)url andValueArr:(NSData *)badyData withInfoDic:(NSDictionary *)dic

{

   NSURL *reqURL = [NSURLURLWithString:url];

    [[UIApplicationsharedApplication]setNetworkActivityIndicatorVisible:YES];

//    NSURL *reqURL = [NSURL URLWithString:protocol_json_url];

    //post 异步请求

    NSMutableURLRequest *request = [NSMutableURLRequestrequestWithURL:reqURL cachePolicy:NSURLRequestReloadIgnoringCacheDatatimeoutInterval:10];

    [requestsetHTTPMethod:@"POST"];

    [requestsetHTTPBody:badyData];

    [NSURLConnectionconnectionWithRequest:request delegate:self];

   self.finish =NO;

   while (!self.finish) {

        [[NSRunLoopcurrentRunLoop] runMode:NSDefaultRunLoopModebeforeDate:[NSDatedistantFuture]];

    }

    [selfretain];

//    //get 异步请求

//    NSURLRequest *request = [NSURLRequest requestWithURL:reqURL];

//    [self retain];

//    NSURLConnection *connection = [NSURLConnection connectionWithRequest:request delegate:self];

//    [connection start];

    

}

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

    

    [[UIApplicationsharedApplication]setNetworkActivityIndicatorVisible:NO];

    

    self.finishBlock(nil);

    [selfrelease];

   self.finish =YES;

}

- (void)connection:(NSURLConnection *)connection didFailWithError:(NSError *)error{

    

    [[UIApplicationsharedApplication]setNetworkActivityIndicatorVisible:NO];

   self.failedBlock(error);

    [selfrelease];

   self.finish =YES;

}
