我正在 iPhone 应用程序上实现 searchdisplay 控制器，但是当我尝试单击搜索栏时会遇到以下错误（经过几次尝试）
Thread 1: EXC_BAD_ACCESS (code=1, address=0x30000008)
我的代码片段如下：
- (void)viewDidLoad
{
//Setting up the search bar for search display controller
UISearchBar *tempBar = [[UISearchBar alloc]initWithFrame:CGRectMake(0, 34, 320, 44)];
self.sBar = tempBar;
[tempBar release];
self.sBar.delegate = self;
self.sBar.tintColor = [UIColor colorWithHexString:@"#b6c0c7"];
self.sBar.placeholder = @"Search DM friends";
self.searchDisplayController = [[[UISearchDisplayController alloc] initWithSearchBar:sBar contentsController:self]autorelease];
[self setSearchDisplayController:searchDisplayController];
[searchDisplayController setDelegate:self];
[searchDisplayController setSearchResultsDataSource:self];
self.searchDisplayController.searchResultsTableView.delegate = self;
}
- (UIView *)tableView:(UITableView *)tableView viewForHeaderInSection:(NSInteger)section
{
UIView *headerView = [[[UIView alloc]initWithFrame:CGRectMake(0, 0, 320, 78)]autorelease];
headerView.backgroundColor = [UIColor colorWithHexString:@"#ebe7e6"];
if (tableView != self.searchDisplayController.searchResultsTableView){
//Search
UILabel *tagFriendsTitle = [[UILabel alloc]initWithFrame:CGRectMake(10, 10, 320, 16)];
tagFriendsTitle.font = [UIFont boldSystemFontOfSize:14];
tagFriendsTitle.backgroundColor = [UIColor clearColor];
tagFriendsTitle.text = @"Who should see this? Tag them!";
[headerView addSubview:tagFriendsTitle];
//THIS IS WHERE I GET MY EXC_BAD_ACCESS error
[headerView addSubview:self.sBar];
[tagFriendsTitle release];
}
return headerView;
}
我不确定我的代码的哪一部分导致了错误，但是当我尝试将 sBar 添加到标题子视图时，它似乎从内存中释放了？但我不知道为什么我需要多次点击搜索栏才能发生这种情况。
这是它在 iPhone 上的样子，搜索栏是 headerview 的一部分
