json 파싱을 AFNetworking으로 만드는 방법

Question

안녕하세요, AFNetworking Framework을 구현하려고합니다. AFNetworking 프레임 워크를 사용하여 json 데이터를 검색하려고합니다. 하지만 AFNetworking 프레임 워크를 사용하여 JSON 데이터를 검색하는 방법을 모른다. 제발 어떤 몸이라도 안내 해줘. https://github.com/AFNetworking/AFNetworking 및 코드 아래 사용 :

-(void)ViewDidLoad 

{ 

    userid=[[NSUserDefaults standardUserDefaults]valueForKey:@"user_id"]; 

    encryptpwd=[[NSUserDefaults standardUserDefaults]valueForKey:@"Encrypt_Psw"]; 

    id=[[NSUserDefaults standardUserDefaults]valueForKey:@"comm_id"]; 

    NSString *strJson=[NSString stringWithFormat:@"userId=%@&encryptPassword=%@&commId=%@",userid,encryptpwd,id]; 

    NSString *strlength=[NSString stringWithFormat:@"%d",[strJson length]]; 

    NSURL *url=[NSURL URLWithString:@“My URL”]; 

    NSMutableURLRequest *request=[NSMutableURLRequest requestWithURL:url]; 

    [request addValue:@"text/html" forHTTPHeaderField:@"Content-Type"]; 

    [request addValue:strlength forHTTPHeaderField:@"Content-Length"]; 

    NSData *requestData=[strJson dataUsingEncoding:NSUTF8StringEncoding]; 

    [request setHTTPBody:requestData]; 

    [request setHTTPMethod:@"Post"]; 

    [[NSURLConnection alloc]initWithRequest:request delegate:self]; 

} 


- (void)connection:(NSURLConnection *)connection didReceiveResponse:(NSURLResponse *)response 

{ 

    responseData=[[NSMutableData alloc]init]; 

} 

- (void)connection:(NSURLConnection *)connection didReceiveData:(NSData *)data 

{ 

    [responseData appendData:data]; 

} 

- (void)connectionDidFinishLoading:(NSURLConnection *)connection 

{ 

    [UIApplication sharedApplication].networkActivityIndicatorVisible=YES; 

    NSError *err; 

    NSString *strResponse=[[NSString alloc]initWithData:responseData encoding:NSUTF8StringEncoding]; 

    NSLog(@"response is %@",strResponse); 

    dit=[NSJSONSerialization JSONObjectWithData:responseData options:NSJSONReadingAllowFragments error:&err]; 

    NSArray *arrResults = [dit valueForKey:@"class_mst"]; 

    listOfObjects = [NSMutableArray array]; 

    for(dictRes in arrResults) 

    { 

     Attributes *at = [[Attributes alloc]init]; 

     at.classimage=[dictRes valueForKey:@"image_name"]; 

     at.classname=[dictRes valueForKey:@"class_title"]; 

     [listOfObjects addObject:at]; 

    } 

    [tableView reloadData]; 

} 


- (void)connection:(NSURLConnection *)connection didFailWithError:(NSError *)error 

{ 

    [UIApplication sharedApplication].networkActivityIndicatorVisible=NO; 

    UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"No Internet Connection" message:@"Please ensure you have internet connection" delegate:nil cancelButtonTitle:@"OK" otherButtonTitles:nil]; 

    [alert show]; 

} 

- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section 

{ 

    return [listOfObjects count]; 

} 

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath 

{ 

    static NSString *identifier=@"cell"; 

    UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:identifier]; 

    if (cell == nil) 

    { 

     cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleSubtitle reuseIdentifier:identifier]; 

    } 

    UIImageView *imageView =[[UIImageView alloc]initWithFrame:CGRectMake(0, 0, 300, 80)]; 

    imageView.tag = 100; 

    [cell.contentView addSubview:imageView]; 

    UILabel *classtitle=[[UILabel alloc]initWithFrame:CGRectMake(5, 120, 200, 20)]; 

    classtitle.highlightedTextColor=[UIColor clearColor]; 

    classtitle.font=[UIFont systemFontOfSize:12.0]; 

    [cell.contentView addSubview:classtitle]; 

    Attributes *att = [listOfObjects objectAtIndex:indexPath.row]; 

    NSString *strf=att.classname; 

    classtitle.text=strf; 

    str=att.classimage; 

    url=@“image URL”; 

    UIImageView *cellImageView = [cell.contentView viewWithTag:100]; 

    // cellImageView.image = nil; 

    if(str!=nil) 

    { 

     dispatch_queue_t queue = dispatch_get_global_queue(DISPATCH_QUEUE_PRIORITY_HIGH, 0ul); 

     dispatch_async(queue, ^(void) 

     { 


      NSString *imageStr = [url stringByAppendingString:str]; 
      UIImage *image = [UIImage imageWithData:[NSData dataWithContentsOfURL:[NSURL URLWithString:imageStr]]]; 

      dispatch_async(dispatch_get_main_queue(), ^{ 

      cellImageView.image = image; 

     }); 

     }); 

    } 

    return cell; 

} 

Answer 1

당신은 아래 링크에서 라이브러리를 AFNetworking 가져올 수 있습니다

NSURL *url = [[NSURL alloc] initWithString:@"YOURURL"]; 

NSMutableURLRequest *request = [[NSMutableURLRequest alloc] initWithURL:url]; 
[request setHTTPMethod:@"POST"]; 
[request addValue:@"application/x-www-form-urlencoded" forHTTPHeaderField:@"Content-Type"]; 
NSString *strJson=[NSString stringWithFormat:@"userId=%@&encryptPassword=%@&commId=%@",userid,encryptpwd,id]; 
[request setHTTPBody:[strJson dataUsingEncoding:NSUTF8StringEncoding]]; 
AFJSONRequestOperation *operation = [AFJSONRequestOperation JSONRequestOperationWithRequest:request success:^(NSURLRequest *request, NSHTTPURLResponse *response, id JSON) { 
    NSDictionary *dict = [[NSDictionary alloc] initWithDictionary:JSON]; 

    NSArray *arrResults = [dict valueForKey:@"class_mst"]; 

    listOfObjects = [NSMutableArray array]; 

    for(dictRes in arrResults) 

    { 

    Attributes *at = [[Attributes alloc]init]; 

    at.classimage=[dictRes valueForKey:@"image_name"]; 

    at.classname=[dictRes valueForKey:@"class_title"]; 

    [listOfObjects addObject:at]; 

    } 

    [tableView reloadData]; 

} 실패 :^(NSURLRequest * 요청, NSHTTPURLResponse * 응답, NSError 이 내 코드입니다 * 오류, ID JSON) { }]; 당신이 AFJSONRequestOperation, 그것은 네트워크를 통해 데이터를 가져 와서 pasred JSON 응답을 제공 할 수 있습니다 당신을 AFNetworking에서

[operation start]; 

Answer 2

. 내 code.i에 같은 일부 남아있는 내 코드에 response.According 또는 변경에 대한 감사

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

      //it give parse json data 
      NSDictionary *dict = [[NSDictionary alloc] initWithDictionary:JSON]; 

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

     }]; 

     [operation start];
