尝试此代码

NSURL *url = [NSURL URLWithString:@"Your Json URL"]; 

    NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:url 
                    cachePolicy:NSURLRequestUseProtocolCachePolicy 
                   timeoutInterval:60.0]; 
      [request setValue:@"application/json" forHTTPHeaderField:@"Accept"]; 
      [request setValue:@"application/json" forHTTPHeaderField:@"Content-Type"]; 

      [request setHTTPMethod:@"POST"]; 

      NSURLResponse *response; 
      NSError *err; 
      NSData *responseData = [NSURLConnection sendSynchronousRequest:request returningResponse:&response error:&err]; 
      NSString *str = [[NSString alloc] initWithData:responseData encoding:NSUTF8StringEncoding]; 
      NSLog(@"responseData in string : %@",str); 

      NSMutableDictionary *dictTemp = [NSJSONSerialization JSONObjectWithData:responseData options:0 error:nil]; 

NSLog(@"responseData in Dictionary : %@",dictTemp);

    -(void)answerCode 
{ 
    NSError * error ; 
    NSURLResponse * urlResponse; 

    NSURL * postUrl =[NSURL URLWithString:YourUrl];//enter your url 

//your body here 
NSString * body =[NSString stringWithFormat:@"email=dharasis"]; 



    NSMutableURLRequest * request =[[NSMutableURLRequest alloc]initWithURL:postUrl cachePolicy:NSURLRequestReloadIgnoringCacheData timeoutInterval:50]; 
    [request setHTTPMethod:@"POST"]; 
    [request setHTTPBody:[body dataUsingEncoding:NSUTF8StringEncoding allowLossyConversion:YES]]; 

    NSData * data =[NSURLConnection sendSynchronousRequest:request returningResponse:&urlResponse error:&error]; 
    if (!data) { 

     return; 
    } 

    id json =[NSJSONSerialization JSONObjectWithData:data options:NSJSONReadingAllowFragments error:&error]; 

    NSLog(@"Json result is:%@",josn); 

}
