ios怎样修改导航栏标题字体样式和颜色

Posted 2023-03-09

iOS 5 以后 UINavigationController 可以 改变UINavigationBar导航条标题颜色和字体
[self.navigationController.navigationBar setTitleTextAttributes:[NSDictionary dictionaryWithObjectsAndKeys:
[UIColor colorWithRed:0 green:0.7 blue:0.8 alpha:1], UITextAttributeTextColor,
[UIColor colorWithRed:0 green:0.7 blue:0.8 alpha:1], UITextAttributeTextShadowColor,
[NSValue valueWithUIOffset:UIOffsetMake(0, 0)], UITextAttributeTextShadowOffset,
[UIFont fontWithName:@"Arial-Bold" size:0.0], UITextAttributeFont,
nil]];
其中 UITextAttributeTextColor和UITextAttributeFont 属性是文字颜色和字体 参考技术A 这个要用自定义的view 才能设置：方法如下
//设置标题

// self.title = @"title1";//修改title 会改变navigationItem。title ，但反之不会，一般设置title用此方法就好了

// self.navigationController.title = @"title2";

//

//自定义标题

// UIView *view = [[UIView alloc] initWithFrame:CGRectMake(0, 0, 100, 44)];

// view.backgroundColor = [UIColor redColor];

UILabel *title = [[UILabel alloc] initWithFrame:CGRectMake(0, 0, 100, 44)];

title.text = @"title3";

title.textAlignment = NSTextAlignmentCenter;

title.textColor = [UIColor redColor];

self.navigationItem.titleView = title; 参考技术B yue yu 越狱
