objective-c - 如何在没有 IB 的情况下将自定义导航栏保留在屏幕底部

Question

我有一个自定义导航栏，当它针对 iphone 5 展开时，我想将其固定到屏幕底部。我只知道如何在 IB 中正确执行此操作，并从开发人员那里继承了代码，

我尝试过:

ICNavbarView *navBarView = [[ICNavbarView alloc] init];
navBarView.delegate = self;
CGRect navBarFrame = navBarView.frame;
navBarFrame.origin.y = self.view.frame.size.height - navBarFrame.size.height;
navBarView.frame = navBarFrame;
[self.view addSubview:navBarView];

////////resize/metrics of Navbar////////
[navBarView setAutoresizingMask:(UIViewAutoresizingFlexibleBottomMargin |     UIViewAutoresizingFlexibleWidth)];

导航栏不动!我是否缺少一种将导航栏随屏幕向下移动而不调整其大小的方法？

Answer 1

改变这个:

[navBarView setAutoresizingMask:(UIViewAutoresizingFlexibleBottomMargin |     UIViewAutoresizingFlexibleWidth)];

到:

[navBarView setAutoresizingMask:(UIViewAutoresizingFlexibleTopMargin |     UIViewAutoresizingFlexibleWidth)];
