我有一个TabBar.我试图设置它的样式,以便TabBarItems上的标题具有正常状态和选定状态的不同字体.对于正常状态,我想要Helvetica Neue Light,对于选定状态,我想要Helvetica Neue Medium.无论我做什么,我似乎都无法让这两种状态的字体不同.颜色变化很好.这是我目前拥有的：
// Set the tab bar title appearance for normal state.
[[UITabBarItem appearance] setTitleTextAttributes:@{
NSFontAttributeName: [UIFont fontWithName:@"HelveticaNeue-Light"
size:16],NSForegroundColorAttributeName: [CMK8Colors grayColor]
}
forState:UIControlStateNormal];
// Set the tab bar title appearance for selected state.
[[UITabBarItem appearance] setTitleTextAttributes:@{
NSFontAttributeName: [UIFont fontWithName:@"HelveticaNeue-Medium"
size:16],NSForegroundColorAttributeName: [CMK8Colors blueColor]
}
forState:UIControlStateSelected];
请帮忙.
解决方法
@H_403_9@ 好消息和坏消息.坏消息,这比使用外观代理要困难一些.
好消息它并没有那么难！
头
#import <UIKit/UIKit.h> @interface MYTabbyViewController : UITabBarController @end
履行
#import "MYTabbyViewController.h"
@implementation MYTabbyViewController
-(void)setSelectedViewController:(UIViewController *)selectedViewController
{
[super setSelectedViewController:selectedViewController];
for (UIViewController *viewController in self.viewControllers) {
if (viewController == selectedViewController) {
[viewController.tabBarItem setTitleTextAttributes:@{
NSFontAttributeName: [UIFont fontWithName:@"HelveticaNeue-Medium" size:16],NSForegroundColorAttributeName: [UIColor blueColor]
}
forState:UIControlStateNormal];
} else {
[viewController.tabBarItem setTitleTextAttributes:@{
NSFontAttributeName: [UIFont fontWithName:@"HelveticaNeue-Light" size:16],NSForegroundColorAttributeName: [UIColor grayColor]
}
forState:UIControlStateNormal];
}
}
}
您将需要的最后一部分是使用此子类而不是开箱即用的UITabBarController.如果您正在使用Storyboard,只需选择TabBarController,转到Identity Inspector(右侧面板中的第三个子选项卡)并将UITabBarController更改为MYTabBarController或您拥有的内容.
但是啊！底线,只需更新ViewController tabBarItem！
