问题描述
从 iOS 5 开始,Apple 提供了一个 API 来自定义 UITabBar
对象中的 UITabBarItems
.我特指以下选择器:
Since iOS 5 Apple provided an API to customise the UITabBarItems
in the UITabBar
object. I am refering specifically to the following selector:
setFinishedSelectedImage:withFinishedUnselectedImage:
这一切都适用于常规按钮,但我似乎无法自定义更多"按钮以匹配其他按钮的样式.这就是我正在做的事情:
It all works great for regular buttons but I can't seem to customise the "More" button to match the style of the other ones. This is what I am doing:
tabBarController.viewControllers = tabBarControllerArray;
tabBarController.moreNavigationController.navigationBar.tintColor = [UIColor blackColor];
UITabBarItem *more = tabBarController.moreNavigationController.tabBarItem;
if ([more respondsToSelector:@selector(setFinishedSelectedImage:withFinishedUnselectedImage:)]){
[more setFinishedSelectedImage:[UIImage imageNamed:@"BarIcon-More.png"]
withFinishedUnselectedImage:[UIImage imageNamed:@"BarIcon-More.png"]
];
} else {
more.image = [UIImage imageNamed:@"BarIcon-More.png"];
}
结果如下,没有拾取我自定义的More图片.
The result is as follows, it doesn't pick-up my custom More image.
我已经看到了许多替换更多按钮的技巧,但是必须有更好的方法来做到这一点吗?
I have seen many hacks to replace the more button but there's got to be a better way of doing this right?
推荐答案
这个解决方案很傻.
我假设 moreNavigationController
中的 UITabBarItems
是只读的,但事实并非如此.所以只需执行以下操作:
I assumed the UITabBarItems
in the moreNavigationController
was readonly and it wasn't. So simply doing the following:
tabBarController.moreNavigationController.tabBarItem = [[UITabBarItem alloc] initWithTitle:@"More" image:[UIImage imageNamed:@"BarIcon-More.png"] tag:0];
和上面一样的自定义代码也可以工作.
And the same customization code as above works.
