您好我在UISerchbar
中使用tableview
,但有没有简单的方法可以在searchbar
中创建自定义tableview headerview
?
我已经查看下面的链接,但我不明白。
Custom UISearchBar with UISearchController
How do I use the UISearchBar and UISearchDisplayController
我添加了searchDisplayController ::
这是我的searchController代码,
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;
我也为UISearchBarDelegate,UISearchResultsUpdating
设置了委托,
并实施了他们的方法,
- (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];
}
取消按钮事件
- (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];
}
仍然无法正常工作
提前致谢:)
答案 0 :(得分:0)
有些事情已经完成,但我有两个小错误。
1)从Storyboard中删除搜索栏。
2)添加[self.searchController.searchBar sizeToFit];
在viewDidLoad
谢谢:))
