AFNetworking使用範例

直接使用

NSURLRequest *request = [NSURLRequest requestWithURL:[NSURL URLWithString:urlstr]];

AFJSONRequestOperation *operation = [AFJSONRequestOperation JSONRequestOperationWithRequest:request success:^(NSURLRequest *request, NSHTTPURLResponse *response, id JSON) {

      

    } failure:^(NSURLRequest *request, NSHTTPURLResponse *response,NSError *error, id JSON) {

        NSLog(@"error:%@,response:%@",error,response);

        

    }];

[operation start];

使用block

Film.m

+ (void)getFilmsTypeWithBlock2:(void (^)(NSArray *films))block{

    MyManager *sharedManager = [MyManager sharedManager];

    

    [[AFVL2APIClient sharedClient] getPath:@"Vl2api.do?opt=getFilmTypeUnderFilmType" parameters:nil success:^(AFHTTPRequestOperation *operation, id JSON) {

       

        NSMutableArray *mutableArray = [NSMutableArray arrayWithCapacity:[JSON count]];

        for (NSDictionary *attributes in JSON) {

            Film *film = [[Film alloc] initWithAttributes:attributes];

            [mutableArray addObject:film];

        }

        

        if (block) {

            block([NSArray arrayWithArray:mutableArray]);

        }

        

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

#if __IPHONE_OS_VERSION_MIN_REQUIRED

        [[[UIAlertView alloc] initWithTitle:NSLocalizedString(@"Error", nil) message:[error localizedDescription] delegate:nil cancelButtonTitle:nil otherButtonTitles:NSLocalizedString(@"OK", nil), nil] show];

#else

        [[NSAlert alertWithMessageText:NSLocalizedString(@"Error", nil) defaultButton:NSLocalizedString(@"OK", nil) alternateButton:nil otherButton:nil informativeTextWithFormat:[error localizedDescription]] runModal];

#endif

        if (block) {

            block(nil);

        }

    }];

    

}

viewController.m

[FilmType getFilmsTypeWithBlock:^(NSArray *films) {

        if(films){

        }

    }];
