（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 = 1 * NSEC_PER_SEC  / 100 ;
//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, 0);
//创建Timer
_timer = dispatch_source_create(DISPATCH_SOURCE_TYPE_TIMER, 0, 0, queue);
//使用dispatch_source_set_timer函数设置timer参数
dispatch_source_set_timer(_timer, dispatch_time(DISPATCH_TIME_NOW, 0), interval, 0);

//设置回调
dispatch_source_set_event_handler(_timer, ^()
{
[self.arrayLock lock];
if([protocolmutableArrays count]>0)
{
NSData* nData = [protocolmutableArrays objectAtIndex:0];
// NSLog(@"Hava received datas is----- :%@",[self nDataToGbkString:nData]);
NSData* d = [nData subdataWithRange:NSMakeRange(5, 3)];

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(10, nData.length-10)]];

}

[protocolmutableArrays removeObjectAtIndex:0];
}
[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:0];
self.SndComicDic = [commicArr objectAtIndex:1];
self.ThdComicDic = [commicArr objectAtIndex:2];
self.FourthComicDic = [@{@"comicContent":@"酒鬼",@"comicId":@"4"} mutableCopy];

}
