Objective-C (iOS) : 레이블의 텍스트를 수정할 수 없습니다.

현재 처음으로 iOS 앱을 작성 중이며 직접 또는 이전 질문에서 확인할 수없는 문제가 발생했습니다. 현재 두 개의 뷰가 있고 하나의 ViewController.m 파일에서 제어되는 앱이 있습니다. 첫 번째보기에서 백분율 버튼을 클릭 할 때 두 번째보기에있는 레이블의 텍스트를 변경하고 싶습니다.

나는 그들을 속성으로 아울렛을 생성하여 레이블을 수정하려고했습니다. 어떤 이유로 코드는 화면에 표시되지 않고 실행됩니다. 이 문제가 현재 설정 한 관계와 관련이 있는지 궁금하거나 레이블을 잘못 부르고 있는지 확실하지 않습니다. 누구든지 나를 도울 수 있다면 대단히 감사하겠습니다. (특히 printResults 메서드에서. 관심있는 사람이있는 경우 워크 플로가 어떻게 보이는지 볼 수있는 링크를 주석에 추가했습니다.)

요약 된 질문 버전 :

// Label I would like to change the text of (in a second view in the same controller)
@property (strong, nonatomic) IBOutlet UILabel *resultTitle;

- (void) printResults:(int) percent :(int) weightOnBar :(Weights*) weightObject{
   // How I am trying to modify the text in a method within the viewcontroller.m file
   [self.fortyFivePlateLabel setText: [NSString stringWithFormat:@"Test"]];
}
