[英]Unable to change UISearchBar cancel button title color after changing it's text.
I'm using this code to change UISearchBar cancel button title: 我正在使用此代码更改UISearchBar取消按钮标题:
-(void)searchDisplayControllerWillBeginSearch:(UISearchDisplayController *)controller{
self.searchDisplayController.searchBar.showsCancelButton = YES;
UIView* view=_otsinguRiba.subviews[0];
for (UIView *subView in view.subviews) {
if ([subView isKindOfClass:[UIButton class]]) {
UIButton *cancelButton = (UIButton*)subView;
if (cancelButton) {
[cancelButton setTitle:@"Test") forState:UIControlStateNormal];
[cancelButton setTitleColor:[UIColor redColor] forState:UIControlStateNormal];
}
}
}
}
While changing the text works fine, changing the color doesn't. 虽然更改文本工作正常,但更改颜色不会。 It stays black.
它保持黑色。
I found the answer to this on SO a while back, but I don't recall where. 我在一段时间后找到了答案,但我不记得在哪里。 Here's the code that I'm using to set the color of the text.
这是我用来设置文本颜色的代码。
[[UIBarButtonItem appearanceWhenContainedIn:[UISearchBar class], nil] setTitleTextAttributes:[NSDictionary dictionaryWithObjectsAndKeys:
[UIColor redColor],NSForegroundColorAttributeName,
//[UIColor whiteColor],UITextAttributeTextShadowColor,
//[NSValue valueWithUIOffset:UIOffsetMake(0, 1)],UITextAttributeTextShadowOffset,
nil]
forState:UIControlStateNormal];
You can take advantage of the iOS Runtime Property _cancelButton
to achieve this. 您可以利用iOS运行时属性
_cancelButton
来实现此目的。
UIButton *cancelButton = [self.searchDisplayController.searchBar valueForKey:@"_cancelButton"];
[cancelButton setTitleColor:[UIColor yourColor] forState:UIControlStateNormal];
