Autoresizingmask立即覆盖最初设置的框架（创build一个不同的和错误的布局）

我正在尝试configuration我的一个视图。 我可以正确设置尺寸，但是当我添加自动调整掩码时，它会立即改变尺寸。

- (void)viewDidLoad { [super viewDidLoad]; // Do any additional setup after loading the view. UIScrollView* scrollView = [[UIScrollView alloc] initWithFrame: CGRectMake(0, 0, self.view.frame.size.width, self.view.frame.size.height - self.tabBarController.tabBar.frame.size.height - self.navigationController.navigationBar.frame.size.height - 10)]; // -10 so I know it's not being hidden under the tabbar scrollView.backgroundColor = [UIColor greenColor]; // easy recognition scrollView.autoresizingMask = UIViewAutoresizingFlexibleHeight | UIViewAutoresizingFlexibleWidth; [self.view addSubview: scrollView]; self.scroll = scrollView; UITapGestureRecognizer* tap = [[UITapGestureRecognizer alloc] initWithTarget: self action:@selector(hmm)]; [self.navigationController.navigationBar addGestureRecognizer: tap]; } - (void) hmm { NSLog(@"Frame: %@", [NSValue valueWithCGRect: self.scroll.frame]); } 

我得到357没有面具和264面具。 在scrollview和tabbar之间有一个很大的白色区域。 为什么这样？ 我该如何解决？

您不需要考虑导航和标签栏。

尝试这个。 当你启动scrollview的时候，你需要在重新resize之前使它成为视图的大小，一旦它加载了你的视图，就会自动重新调整视图的大小。

 - (void)viewDidLoad { [super viewDidLoad]; // Do any additional setup after loading the view. UIScrollView* scrollView = [[UIScrollView alloc] initWithFrame: CGRectMake(0, 0, self.view.frame.size.width, self.view.frame.size.height- 10)]; // -10 so I know it's not being hidden under the tabbar scrollView.backgroundColor = [UIColor greenColor]; // easy recognition scrollView.autoresizingMask = UIViewAutoresizingFlexibleHeight | UIViewAutoresizingFlexibleWidth; [self.view addSubview: scrollView]; self.scroll = scrollView; UITapGestureRecognizer* tap = [[UITapGestureRecognizer alloc] initWithTarget: self action:@selector(hmm)]; [self.navigationController.navigationBar addGestureRecognizer: tap]; }
