在我的 Xcode 项目中,我有一个带有元素的 TableView,我添加了一个带有 Apple 的“令人惊叹的新”UISearchController 的搜索栏。它运行良好了一点,但现在没有在 UISearchController 上调用“cellForRowAtIndexPath”。结果通过,我 NSLogg'ed 计数,但单元格未配置。知道为什么会这样吗?
TableViewController.m:
- (void)viewDidLoad {
[super viewDidLoad];
self.listTableView.tableFooterView = [[UIView alloc] init];
// Create new HomeModel object and assign it to _homeModel variable
_displayModel = [[DisplayModel alloc]init];
_displayModel.delegate = self;
[_displayModel downloadItems];
_listTableView.delegate = self;
// Set this view controller object as the delegate for the home model object
self.filteredArray = [NSMutableArray arrayWithCapacity:[self.athletes count]];
#define ENABLE_SCOPE_BUTTONS 0
// The table view controller is in a nav controller, and so the containing nav controller is the 'search results controller'
UINavigationController *searchResultsController = [[self storyboard] instantiateViewControllerWithIdentifier:@"TableSearchResultsNavController"];
self.searchController = [[UISearchController alloc] initWithSearchResultsController:searchResultsController];
self.searchController.searchResultsUpdater = self;
self.searchController.searchBar.frame = CGRectMake(self.searchController.searchBar.frame.origin.x, self.searchController.searchBar.frame.origin.y, self.searchController.searchBar.frame.size.width, 44.0);
self.listTableView.tableHeaderView = self.searchController.searchBar;
#if ENABLE_SCOPE_BUTTONS
NSMutableArray *scopeButtonTitles = [[NSMutableArray alloc] init];
[scopeButtonTitles addObject:NSLocalizedString(@"All", @"Search display controller All button.")];
for (NSString *sport in [Athlete sportTypeNames]) {
NSString *displayName = [Product displayNameForType:deviceType];
[scopeButtonTitles addObject:displayName];
}
self.searchController.searchBar.scopeButtonTitles = scopeButtonTitles;
self.searchController.searchBar.delegate = self;
#endif
//self.searchController.searchBar.scopeButtonTitles = scopeButtonTitles;
self.searchController.searchBar.delegate = self;
self.definesPresentationContext = YES;
;
// Do any additional setup after loading the view, typically from a nib.

DetailViewController *vc = [[self storyboard] instantiateViewControllerWithIdentifier:@"DetailViewController"];
self.presentingViewController.navigationItem.title = @"Search";
vc.athlete = athlete;
[self.presentingViewController.navigationController pushViewController:vc animated:YES];
}
-(void)viewDidLoad{
Athlete *athlete = [self.searchResults objectAtIndex:0];
self.tableView = self.tableView;
self.tableView.frame = CGRectMake(0, 0, 320, 480);
NSLog(@"Name: %@", athlete.name);
}
@end
最佳答案
假设委托(delegate)和数据源已设置 - 有或没有搜索栏 - 像 CellforRowAtIndexPath 这样的 UITableview 方法在被这个语句触发时按顺序一个接一个地执行
[self.myTable reloadData];
只是想知道如果您有 Searchbar/SearchCONtroller - 搜索逻辑在哪里
- (void)searchBarSearchButtonClicked:(UISearchBar *)searchBar {
// ....
[self.myTable reloadData];
}
关于ios - iOS 上的 UISearchController 不调用 cellForRowAtIndexPath,我们在Stack Overflow上找到一个类似的问题: https://stackoverflow.com/questions/27894307/
