Question

我正在尝试在多个视图控制器上使用Nstimer视图转换，但如果我复制并粘贴它，我会收到错误说明方法的重复声明。我该如何解决？请在你的回答中解释如何做到这一点。我从这个链接中找到了如何做到这一点。

- (void)viewDidAppear:(BOOL)animated {
    [self startTimerMethod];
}

- (void) startTimerMethod {
    transitionTimer = [NSTimer scheduledTimerWithTimeInterval:5.0 target:self selector:@selector(transitionView) userInfo:nil repeats:NO];
}

- (void) transitionView {
    [self performSegueWithIdentifier:@"viewTransition" sender:self];
}

- (void)viewDidAppear:(BOOL)animated {
    [self startTimerMethod];
}
- (void) startTimerMethod {
    transitionTimer = [NSTimer scheduledTimerWithTimeInterval:5.0 target:self selector:@selector(transitionView) userInfo:nil repeats:NO];
}

- (void) transitionView {
    [self performSegueWithIdentifier:@"viewTransition" sender:self];
}

您可以将以下三种方法复制并粘贴两次，让它定义或声明单次： -

  -(void)viewDidAppear:(BOOL)animated

    -(void) startTimerMethod

   -(void) transitionView
