我如何比较字符串和整数？

Question

我基本上不了解目标c,但是我如何制作一个if语句来查看SourceTypeString是否等于1或2？

     NSString* sourceTypeString = [arguments objectAtIndex:2];
            UIImagePickerControllerSourceType sourceType = UIImagePickerControllerSourceTypeCamera; // default
            NSLog(@"my ns string = %@",sourceTypeString);
  //NEWBIE PART
        if ((sourceTypeString == 1))
            {
            NSLog(@"equals 1");
                sourceType = (UIImagePickerControllerSourceType)[sourceTypeString intValue];
            } else {
            NSLog(@"equals 2");
            sourceType = UIImagePickerControllerSourceTypePhotoLibrary;
        }
   //NEWBIE PART

我的代码崩溃并给了我

my ns string = 1
(lldb) 
sourceTypeString    __NSCFNumber *  0x0013bf80 (int)1

if ([sourceTypeString intValue] == 1)
