我有这样的问题:如何隐藏UISearchBar的取消按钮?
我已经对UISearchController
和UISearchBar
进行了子类化,并在UISearchBar
中覆盖了layoutSubviews
方法。
如何使用自定义的UISearchBar
重写我的自定义UISearchController
中的searchBar
属性?
更新1
为了实现具有自定义UISearchBar
的属性,我在MyUISearchController
中进行了以下操作:
@property(nonatomic, strong, readonly) UISearchBar *searchBar;
和
@synthesize searchBar=_searchBar;
- (UISearchBar *)searchBar {
return [MySearchBar new];
}
但是UISearchController
无论如何都使用默认的searchBar
。
更新
在h
文件中:
@interface MySearchController : UISearchController <UITableViewDelegate, UITableViewDataSource>
在m
文件中:
@interface MySearchController () <UISearchDisplayDelegate, UISearchControllerDelegate,
UISearchBarDelegate, UISearchResultsUpdating, SearchAutocompleteLoader>
@property UISearchController *searchController;
@property (strong, nonatomic) UITableView *searchResultTable;
@property UIView *viewForSearchBar;
@property (nonatomic) NSInteger filterSettings;
@property (strong, nonatomic) UILabel *matchesLabel;
@property (strong, nonatomic) UIView *loading;
@property (strong, nonatomic) UIView *foggView;
@end
- (instancetype)initWith:(UIView *)viewForSearch foggView:(UIView *)view delegate:(id)delegate andResultTableView:(UITableView *)tableView
{
self.viewForSearchBar = viewForSearch;
self.searchResultTable = tableView;
self.foggView = view;
self.searchDelegate = delegate;
[self configureSearchController];
return self;
}
- (void)configureSearchController {
self.searchController = [[UISearchController alloc] initWithSearchResultsController:nil];
self.searchController.searchResultsUpdater = self;
self.searchController.delegate = self;
self.searchController.hidesNavigationBarDuringPresentation = NO;
self.searchController.dimsBackgroundDuringPresentation = NO;
[self loadFilterSettings];
self.searchController.searchBar.delegate = self;
[self.searchController.searchBar setShowsCancelButton:NO];
//self.searchController.searchBar.searchBarStyle = UISearchBarStyleDefault;
[self.searchController.searchBar setBackgroundImage:[UIImage imageWithCGImage:(__bridge CGImageRef)([UIColor clearColor])]];
[self.searchController.searchBar setImage:[UIImage imageNamed:@"iconSearchSettings"] forSearchBarIcon:UISearchBarIconBookmark state:UIControlStateNormal];
self.searchController.searchBar.frame = CGRectMake(0, 0, self.view.frame.size.width, self.viewForSearchBar.frame.size.height);
self.viewForSearchBar.tintColor = [UIColor yellowColor];
// [self.viewForSearchBar addSubview:self.searchController.searchBar];
self.searchController.searchBar.barTintColor = [UIColor whiteColor];
self.searchController.searchBar.tintColor = [UIColor blackColor];
//self.searchController.searchBar.backgroundColor = [UIColor whiteColor];
[self.viewForSearchBar addSubview:self.searchController.searchBar];
for (UIView *subView in self.searchController.searchBar.subviews) {
if ([subView isKindOfClass:[UITextField class]]) {
[subView setTintColor:[UIColor blueColor]];
[[(UITextField *) subView valueForKey:@"textInputTraits"] setValue:[UIColor blueColor] forKey:@"insertionPointColor"];
}
}
[self.searchController setActive:YES];
[self.searchController setActive:NO];
}
searchBar
的唯一原因吗? - Warif Akhand Rishi
