UISearchBar取消按钮颜色? [英] UISearchBar cancel button color?
问题描述
当我在Interface Builder中将UISearchBar放入我的视图,并将其样式更改为黑色不透明时,取消按钮保持不适合的蓝色/灰色,不会变黑。
When I drop a UISearchBar into my view inside Interface Builder, and change its style to Black Opaque, the cancel button stays unfittingly blue / gray and doesn't become black.
如何使取消按钮变为黑色?
How can I make the cancel button black?
编辑:它的工作方式如下:
It does work like this:
// Assume a UISearchBar searchBar.
NSArray *subviews = [searchBar subviews];
// The index depends on how you configure the searchBar.
UIButton *cancelButton = [subviews objectAtIndex:3];
// Set the style to "normal" style.
[cancelButton setStyle:0];
但是 setStyle:
私人框架,所以这可能是一个问题,当提交应用程序到苹果。
But the setStyle:
method is from a private framework, so this might be an issue when submitting the app to Apple.
推荐答案
我使用了一些这样的工作,我:
I used some thing like this and worked with me:
[[UIBarButtonItem appearanceWhenContainedIn: [UISearchBar class], nil] setTintColor:[UIColor blackColor]];
它将取消按钮的颜色更改为黑色。
it changed the cancel button color to black.
更新(对于iOS 9.0),不推荐使用 appearanceWhenContainedIn
的方法,而改用 appearanceWhenContainedInInstancesOfClasses
:
Update for iOS 9.0, the method appearanceWhenContainedIn
is deprecated, use appearanceWhenContainedInInstancesOfClasses
instead:
[[UIBarButtonItem appearanceWhenContainedInInstancesOfClasses:@[[UISearchBar class]]] setTintColor:[UIColor blackColor]];
在Swift中:
(UIBarButtonItem.appearanceWhenContainedInInstancesOfClasses([UISearchBar.self])).tintColor = UIColor.blackColor()
