有一种方法做你想要达到的目标，但一定要适可而止。太多的单身使用的通常被认为是不好的做法。

做一个辛格尔顿，你可以在你的应用程序中使用。

在你单身：APISingleton

-(void)APIRequestWithParams:(NSMutableDictionary*)params 
     onCompletion:(JSONResponseBlock)completionBlock 
      onFailure:(OperationFailureBlock)failureBlock{ 
AFHTTPRequestOperationManager *manager = [AFHTTPRequestOperationManager manager]; 
[manager.requestSerializer setCachePolicy:NSURLRequestReloadIgnoringLocalCacheData]; 
[manager GET:kGymEverAPIfullUrl 
    parameters:params 
    success:^(AFHTTPRequestOperation *operation, id responseObject) { 
     completionBlock(responseObject); 
    } failure:^(AFHTTPRequestOperation *operation, NSError *error) { 
     failureBlock(operation); 
    }];} 

如何使用：

-(void)getImages{ 

NSMutableDictionary *params = [[NSMutableDictionary alloc]initWithObjectsAndKeys:[NSString stringWithFormat:@"%ld",1],@"page",@"5",@"count", nil]; 

[[APISingleton sharedInstance] APIRequestWithParams:params onCompletion:^(id json) { 
    postsArray = [json objectForKey:@"posts"]; 
    [self downloadImages]; 
} onFailure:^(AFHTTPRequestOperation *operation) { 
    //Do whatever you want if it does not work. 
}];}
