返回按钮部分默认是蓝色,如有两个controller,A和B,其中A跳往B。在A中有
ViewControllerB *BVc = [[WeChatSearchViewController alloc]init];
[self.navigationController pushViewController:BVc animated:YES];
那么有两种方式可以修改
①可以在B中(不是A)的viewDidLoad或viewWillAppear写
self.navigationController.navigationBar.tintColor = [UIColor whiteColor];
这样只修改B界面的颜色
②在A中的viewWillAppear或viewDidLoad写
[[UINavigationBar appearance] setTintColor:[UIColor whiteColor]];
这种写法是全局的,会将所有由A跳往的界面的导航栏返回按钮和箭头颜色改变

如conA跳往conB,那么在conB的viewDidLoad中可以添加
-(void)createNav{ UIButton *navLeft = [UIButton buttonWithType:UIButtonTypeCustom]; navLeft.size = CGSizeMake(40, 40); [navLeft setImage:[UIImage imageNamed:@"top_icon_back"] forState:UIControlStateNormal]; [navLeft addTarget:self action:@selector(clickTheBackBtn) forControlEvents:UIControlEventTouchUpInside]; self.navigationItem.leftBarButtonItem = [[UIBarButtonItem alloc] initWithCustomView:navLeft]; }
-(void)clickTheBackBtn{ [self.navigationController popViewControllerAnimated:YES]; }
如若conB为webview的控制器,那么点击返回按钮事件可以这样写
-(void)clickTheBackBtn{ if ([self.webView canGoBack]) { [self.webView goBack]; } else { [self.navigationController popViewControllerAnimated:YES]; } }
效果为
比系统自带的返回按钮看着简约
