如何隐藏导航栏的返回按钮

Answer 1

隐藏导航栏或返回按钮
1 - (void)viewWillAppear:(BOOL)animated
2 {
3 [super viewWillAppear:animated];
4 [self.navigationController setNavigationBarHidden:YES animated:YES]; // 隐藏导航栏
5 [self.navigationItemsetHidesBackButton:YES]; // 隐藏返回按钮
5 }

1 左右键则可以用
2 self.navigationItem.leftBarButtonItem.hidden = YES;

Answer 2

[objc] view plaincopy
//set NavigationBar 背景颜色&title 颜色
[self.navigationController.navigationBar setBarTintColor:[UIColor colorWithRed:20/255.0 green:155/255.0 blue:213/255.0 alpha:1.0]];
[self.navigationController.navigationBar setTitleTextAttributes:[NSDictionary dictionaryWithObjectsAndKeys:[UIColor whiteColor],UITextAttributeTextColor,nil]];
效果如下：

我们把背景改成了蓝色，title文字改成了白色，是不是很简单呢？NavigationBar极其push过去的子页面也会是你修改后的背景颜色
