[英]how to change the UISearchBar to replace the search icon inside the text field with text
我有UISearchBar,我想删除搜索标记(放大镜图标)并放置文本而不是它
You Can Change the magnify Icon in the following way , adapt it to your needs :- 您可以通过以下方式更改放大图标,使其适应您的需求: -
#import <UIKit/UIKit.h>
@interface SearchBoxExperimentsViewController : UIViewController {
IBOutlet UISearchBar *searchBar;
}
@end
#import "SearchBoxExperimentsViewController.h"
@interface SearchBoxExperimentsViewController (Private)
- (void)setSearchIconToFavicon;
@end
@implementation SearchBoxExperimentsViewController
- (void)viewDidLoad
{
[self setSearchIconToFavicon];
[super viewDidLoad];
}
#pragma mark Private
- (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];
}
}
@end
It worked for me :) 它对我有用:)
You can use UIAppearance method 您可以使用UIAppearance方法
Swift 3.0 Swift 3.0
UISearchBar.appearance().setImage(UIImage(named: "image_name"), for: .search, state: .normal)
Objective-c Objective-C的
[[UISearchBar appearance] setImage:[UIImage imageNamed:@"image_name"] forSearchBarIcon:UISearchBarIconSearch state:UIControlStateNormal];
Something a little more approved-API friendly is to use a normal UITextField instead, with the following code to add a label within the UITextField (if you want to remove the magnifying glass, what's your attraction to the search box anyway?): 更友好的API-API更友好的是使用普通的UITextField,使用以下代码在UITextField中添加标签(如果你想删除放大镜,那么你对搜索框的吸引力是什么?):
UILabel *searchFieldLeftLabel = [[UILabel alloc] initWithFrame:CGRectMake(5, 0, 32, 15)];
searchFieldLeftLabel.text = @"find:";
searchFieldLeftLabel.placeholder = @"e.g. wings, Boathouse";
searchFieldLeftLabel.font = [UIFont systemFontOfSize:14];
searchFieldLeftLabel.textColor = [UIColor grayColor];
self.searchFieldLeftLabel.leftView = locationSearchFieldLeftLabel;
[searchFieldLeftLabel release];
The result is a nice looking text box that looks like: 结果是一个漂亮的文本框,看起来像:
And when you start typing text, it replaces the placeholder, but the label remains: 当您开始键入文本时,它会替换占位符,但标签仍然是:
See this post Removing the image on the left of an UISearchbar . 请参阅此文章删除UISearchbar左侧的图像 。 There is no public API to change or remove the magnifier and you should just use a UITextField.
没有公共API可以更改或删除放大镜,您应该只使用UITextField。
