您好,我在tableview
中使用UISerchbar
,但有沒有簡單的方法可以在tableview headerview
中創建自定義searchbar
?iOS中的自定義搜索欄
我已經檢查下面的鏈接,但我不明白。
Custom UISearchBar with UISearchController
How do I use the UISearchBar and UISearchDisplayController
,這是我的searchController代碼,
self.searchController = [[UISearchController alloc] initWithSearchResultsController:nil];
self.searchController.searchResultsUpdater = self;
self.searchController.dimsBackgroundDuringPresentation = NO;
self.searchController.searchBar.delegate = self;
self.definesPresentationContext = YES;
[self.searchController.searchBar setBarTintColor:[UIColor darkGrayColor]];
self.tableView.tableHeaderView = self.searchController.searchBar;
我爲UISearchBarDelegate,UISearchResultsUpdating
設置委託爲好,
並實現他們的方法,
- (void)filterContentForSearchText:(NSString*)searchText scope:(NSString*)scope
{
if (_searchController.isActive && _searchController.searchBar.text.length >0){
NSPredicate *resultPredicate = [NSPredicate
predicateWithFormat:@"SELF.name contains[cd] %@",
searchText];
abcd = [sortedEventArray filteredArrayUsingPredicate:resultPredicate];
NSLog(@"%@",searchResults);
}
}
- (void)updateSearchResultsForSearchController:(UISearchController *)searchController1
{
NSString *searchString = searchController1.searchBar.text;
[self filterContentForSearchText:searchString scope:@"abc"];
//[self filterContentForSearchText:searchString :@"abc"];
[self.tableView reloadData];
}
取消按鈕事件
- (void)searchBarCancelButtonClicked:(UISearchBar *)searchBar
{
abcd=[sortedEventArray mutableCopy];
[_tableView reloadData];
}
-(void)delete{
NSManagedObjectContext *context = [self managedObjectContext];
NSFetchRequest * allMovies = [[NSFetchRequest alloc] init];
[allMovies setEntity:[NSEntityDescription entityForName:@"Data" inManagedObjectContext:context]];
[allMovies setIncludesPropertyValues:NO]; //only fetch the managedObjectID
NSError * error = nil;
NSArray * movies = [context executeFetchRequest:allMovies error:&error];
//error handling goes here
for (NSManagedObject * movie in movies) {
[context deleteObject:movie];
}
NSError *saveError = nil;
[context save:&saveError];
}
提前:)不過它不工作
感謝
我曾在這個很長一段時間,最後決定這將是容易只是放置在一個視圖中的搜索欄右邊的表上方。通過自動佈局,很容易控制定位並使標題始終處於同一位置,IIRC是問題所在。 我放棄了它。祝你好運找到解決方法(我想我當時在ios7上)。 – RegularExpression
