（whh仅供自己参考）进行ip网络请求的步骤

这个过程大致是这个样子：

1 添加通知

2 发送网络请求 里边有一个发送通知的操作

3 执行发送通知的具体操作

代码如下:

1 在VC添加通知

 [[NSNotificationCenter defaultCenter] addObserver:self

                                             selector:@selector(receivingYM1:)

                                                 name:@"YM1" object:nil];
   

2 在SYNDispatchProcessor.m 中进行发送通知

-(void) delayTimeGCDbuild

{

//    NSLog(@"主线程 %@", [NSThread  currentThread]);

    //间隔还是1秒

    uint64_t interval =  * NSEC_PER_SEC  /  ;

    //创建一个专门执行timer回调的GCD队列

//    dispatch_queue_t queue = dispatch_queue_create("my queue", 0);

     dispatch_queue_t queue = dispatch_get_global_queue(DISPATCH_QUEUE_PRIORITY_DEFAULT, );

    //创建Timer

    _timer = dispatch_source_create(DISPATCH_SOURCE_TYPE_TIMER, , , queue);

    //使用dispatch_source_set_timer函数设置timer参数

    dispatch_source_set_timer(_timer, dispatch_time(DISPATCH_TIME_NOW, ), interval, );

    //设置回调

    dispatch_source_set_event_handler(_timer, ^()

    {

        [self.arrayLock lock];

        if([protocolmutableArrays count]>)

        {

            NSData* nData = [protocolmutableArrays objectAtIndex:];

           // NSLog(@"Hava received datas is----- :%@",[self nDataToGbkString:nData]);

            NSData* d = [nData subdataWithRange:NSMakeRange(, )];

            NSString* aStr = [[NSString alloc] initWithData:d encoding:NSASCIIStringEncoding];

           NSLog(@"在这里进行类型的判断：%@",aStr);

            {

                //在这里发送通知

                [[NSNotificationCenter defaultCenter] postNotificationName:aStr object:[nData subdataWithRange:NSMakeRange(, nData.length-)]];

            }

            [protocolmutableArrays removeObjectAtIndex:];

        }

       [self.arrayLock unlock];

    });

3 执行发送通知的事件

//发送完通知之后接收到漫画数据

- (void) receivingYM1:(NSNotification*) anotification

{

    //收到的是漫画的4个cell的大图跟一些相关信息

    NSData* nsData =  [anotification object];

    NSString *string = [[NSString alloc]initWithData:nsData encoding:NSUTF8StringEncoding];

    NSLog(@"nsdata:%@",string);

    [self performSelectorOnMainThread:@selector(updateResgContollerYM1:) withObject:nsData waitUntilDone:YES];

}

//更新幽默坊漫画ui

-(void) updateResgContollerYM1:(id) data

{

    //将data转换成字典类型

    NSDictionary* YM1Dict = [NSJSONSerialization JSONObjectWithData:data options:NSJSONReadingMutableContainers error:nil];

    //用数组进行接收

    NSMutableArray *commicArr = [YM1Dict valueForKey:@"comicList"];

    //将数据存到字典中

    self.FirComicDic = [commicArr objectAtIndex:];

    self.SndComicDic = [commicArr objectAtIndex:];

    self.ThdComicDic = [commicArr objectAtIndex:];

    self.FourthComicDic = [@{@"comicContent":@"酒鬼",@"comicId":@""} mutableCopy];

}
