我想使自己的Navigationbar
变色。所以我在ViewDidLoad
中尝试了这样
self.navigationController.navigationBar.hidden=NO;
[self.navigationController.navigationBar setBackgroundImage:[UIImage new] forBarMetrics:UIBarMetricsDefault];
self.navigationController.navigationBar.shadowImage=[UIImage new];
self.navigationController.navigationBar.translucent=YES;
self.navigationController.navigationBar.topItem.titleView.tintColor=[UIColor blackColor];
self.navigationController.navigationBar.topItem.title=[lan GetConvertedLanguageString:@"My Profile"];
self.navigationController.navigationBar.titleTextAttributes = [NSDictionary dictionaryWithObject:[UIColor whiteColor] forKey:NSForegroundColorAttributeName];
self.navigationItem.leftBarButtonItem = [[UIBarButtonItem alloc] initWithImage:[UIImage imageNamed:@"backarrow"] style:UIBarButtonItemStylePlain target:self action:@selector(revealToggle :)];
[self.navigationController navigationBar].tintColor = [UIColor whiteColor];
但是在我的视图控制器中什么都看不到。此代码有什么问题?请帮我。
谢谢
最佳答案
屏幕截图
码
[self.navigationController.navigationBar setBackgroundImage:[UIImage new] forBarMetrics:UIBarMetricsDefault];
self.navigationController.navigationBar.shadowImage=[UIImage new];
self.navigationItem.title = @"1234";
self.navigationItem.leftBarButtonItem = [[UIBarButtonItem alloc] initWithTitle:@"Left" style:UIBarButtonItemStylePlain target:nil action:nil];
self.navigationController.navigationBar.titleTextAttributes = [NSDictionary dictionaryWithObject:[UIColor whiteColor] forKey:NSForegroundColorAttributeName];
[self.navigationController navigationBar].tintColor = [UIColor whiteColor];
因此,我想您的“视图”背景为白色,因此您看不到白色文本。
注意
navigationBar.titleTextAttributes
显示栏标题文本的属性。
navigationBar.tintColor
应用于导航项目和条形按钮项目的颜色。
