问题描述
我正在尝试自定义搜索栏。我已经想出如何更改搜索栏中的背景和文本框,但我找不到更改栏中默认图标的方法(放大玻璃图标)。
I'm trying to customize a search bar. I've figured out how to change the background and the text box within the search bar, but I can't find a way to change the icon that is default in the bar (the magnify glass icon).
有没有办法做到这一点?
Is there a way to do this?
推荐答案
Open-source 是你的朋友(就像可可一样,呵呵):
Open-source is your friend (just like cocoa is, huh):
- (void)setSearchIconToFavicon {
// Really a UISearchBarTextField, but the header is private.
UITextField *searchField = nil;
for (UIView *subview in searchBar.subviews) {
if ([subview isKindOfClass:[UITextField class]]) {
searchField = (UITextField *)subview;
break;
}
}
if (searchField) {
UIImage *image = [UIImage imageNamed: @"favicon.png"];
UIImageView *iView = [[UIImageView alloc] initWithImage:image];
searchField.leftView = iView;
[iView release];
}
}
自iOS 5.0起:
[self.testSearchBar setImage:[UIImage imageNamed: @"favicon.png"]
forSearchBarIcon:UISearchBarIconSearch
state:UIControlStateNormal];
