Ios 在AFNetworking 2.0中有没有一种简化代码的方法？

现在，在我的代码中，我有很多以下代码块的副本：

NSString *imageID = [postURL.path substringFromIndex:1];
NSString *APILink = [NSString stringWithFormat:@"https://api.imgur.com/3/image/%@", imageID];

AFHTTPRequestOperationManager *operationManager = [AFHTTPRequestOperationManager manager];
[operationManager.requestSerializer setValue:@"Client-ID --myID--" forHTTPHeaderField:@"Authorization"];

[operationManager GET:APILink
           parameters:nil
              success:^(AFHTTPRequestOperation *operation, id responseObject) { 
                         ....

---

有没有办法将其简化为更可重用的代码块？我记得在AFNetworking 1.0中将

AFHTTPClient子类化以实现类似的功能，但我不清楚如何在AFNetworking 2.0中实现它。
您可以将代码放入
AFHTTPRequestOperationManager
类别中的方法中：

如果我分析的代码正确：

myservicesapiaaddition.h

@interface AFHTTPRequestOperationManager(MyServicesAPIAddition)
+ (void)resourceWithURL:(NSURL*)URL clientID:(NSString *)clientID completionHandler:(void (^)(AFHTTPRequestOperation *operation, id responseObject))handler;
@end

myservicesapiaaddition.m

@implementation AFHTTPRequestOperationManager(MyServicesAPIAddition)
+ (void)resourceWithURL:(NSURL*)URL clientID:(NSString *)clientID completionHandler:(void (^)(AFHTTPRequestOperation *operation, id responseObject))handler
{
    NSString *imageID = [URL.path substringFromIndex:1];
    NSString *APILink = [NSString stringWithFormat:@"https://api.imgur.com/3/image/%@", imageID];

AFHTTPRequestOperationManager *operationManager = [AFHTTPRequestOperationManager manager];
[operationManager.requestSerializer setValue:[NSString stringWithFormat:@"Client-ID %@", clientID] forHTTPHeaderField:@"Authorization"];

[operationManager GET:APILink
           parameters:nil
              success:handler];
}
@end

然后：

[AFHTTPRequestOperationManager resourceWithURL:postURL clientID:… completionHandler:
^(AFHTTPRequestOperation *operation, id responseObject) 
{
…
}

人们希望在方法名称中添加后缀，以防止选择器冲突。我没有
