我们如何在objecitve-c中传递参数和块方法

Question

我想通过＆＃39; NSString＆＃39;作为下面方法中作为URLString的参数，我们该怎么做呢

-(void)makeServiceCallSuccess:(void (^)(NSDictionary *response))success
       failure:(void (^)(NSError *error))failure {

AFHTTPRequestOperationManager *manager = [AFHTTPRequestOperationManager manager];
[manager GET:URLString parameters:nil success:^(AFHTTPRequestOperation *operation, id responseObject) {

    response = (NSDictionary *)responseObject;
    success(response);
    NSLog(@"JSON: %@", response);

} failure:^(AFHTTPRequestOperation *operation, NSError *error) {

    failure(error);
    NSLog(@"Error: %@", error);
}];
}

Answer 1

只需在方法中添加参数，通常我们就像

一样

-(void)makeServiceCallSuccessWithURLString:(NSString*)urlString withResponseHandler:(void (^)(NSDictionary *response))success
   failure:(void (^)(NSError *error))failure

Answer 2

没有wat可以在该方法中传递参数，您可以编辑它并添加参数或从aproperty中读取值

-(void)makeServiceCallSuccess:(void (^)(NSDictionary *response))success
   failure:(void (^)(NSError *error))failure {

   NSString* myString = self.myProperty;

   AFHTTPRequestOperationManager *manager = [AFHTTPRequestOperationManager manager];
   [manager GET:myString parameters:nil success:^(AFHTTPRequestOperation *operation, id responseObject) {

    response = (NSDictionary *)responseObject;
    success(response);
    NSLog(@"JSON: %@", response);

 } failure:^(AFHTTPRequestOperation *operation, NSError *error) {

     failure(error);
     NSLog(@"Error: %@", error);
}];
}
