ios7下uisearchbar会消失
在ios下的一个tableview下我添加了下面代码:
//创建搜索栏和搜索显示控制器
_searchBar = [[UISearchBar alloc] initWithFrame:CGRectMake(0, 0, BOUNDSSIZE.width, 44)];
_searchBar.autocorrectionType = UITextAutocorrectionTypeNo;
_searchBar.autocapitalizationType = UITextAutocapitalizationTypeNone;
_searchBar.keyboardType = UIKeyboardTypeAlphabet;
_searchBar.placeholder = [NSString stringWithCString:"搜索(请输入项目关键字) " encoding: NSUTF8StringEncoding];
self.tableView.tableHeaderView = _searchBar;
_searchDc=[[UISearchDisplayController alloc] initWithSearchBar:_searchBar contentsController:self];
_searchDc.searchResultsDataSource=self;
_searchDc.searchResultsDelegate=self;
就添加了一个searchBar在tableview上面,可是我对着tableview或者那个searchBar点了几次之后它会突然消失,怎么回事
我是老司机
