【问题标题】:Change color of inactive tab-bar icons更改非活动标签栏图标的颜色
【发布时间】:2014-09-16 05:35:58
【问题描述】:
我尝试更改标签栏项目的颜色,因为它在非活动状态下始终为灰色,在活动状态下始终为蓝色。
因此,经过一番搜索后,我尝试将这段代码编写为 Tab bar 的所有 ViewControllers
self.tabBarItem.selectedImage = [[UIImage imageNamed:@"TabBarItemMenu_tabbed.png"]
imageWithRenderingMode:UIImageRenderingModeAlwaysOriginal];
self.tabBarItem.image = [[UIImage imageNamed:@"TabBarItemMenu.png"]
imageWithRenderingMode:UIImageRenderingModeAlwaysOriginal];
但这对我没有帮助,而且我总是得到

【解决方案1】:
您还可以这样做:
设置标签栏tintColor属性设置选中图标的颜色
self.tabBar.tintColor = [UIColor redColor];
然后你可以使用文本属性给文本重新着色
for (UITabBarItem *item in self.tabBar.items) {
NSDictionary *normalState = @{UITextAttributeTextColor : [UIColor colorWithWhite:1.000 alpha:1.000],
UITextAttributeTextShadowColor: [UIColor clearColor],
UITextAttributeTextShadowOffset: [NSValue valueWithUIOffset:UIOffsetMake(0.0, 1.0)]};
[item setTitleTextAttributes:normalState forState:UIControlStateNormal];
NSDictionary *selectedState = @{UITextAttributeTextColor : [UIColor redColor],
UITextAttributeTextShadowColor: [UIColor clearColor],
UITextAttributeTextShadowOffset: [NSValue valueWithUIOffset:UIOffsetMake(0.0, 1.0)]};
[item setTitleTextAttributes:selectedState forState:UIControlStateHighlighted];
}
// 编辑
由于 iOS7 不推荐使用上层代码,这里更新:
[[UITabBarItem appearance] setTitleTextAttributes:[NSDictionary dictionaryWithObjectsAndKeys:
[UIColor whiteColor], NSForegroundColorAttributeName,
nil] forState:UIControlStateNormal];
[[UITabBarItem appearance] setTitleTextAttributes:[NSDictionary dictionaryWithObjectsAndKeys:
[UIColor redColor], NSForegroundColorAttributeName,
nil] forState:UIControlStateSelected];
