iPhone开发之UISearchBar的使用方法

UISearchBar是个很不错的东东，集成了搜索输入框和搜索按钮，使用起来也灰常方便。

/*搜索按钮*/- (void)searchBarCancelButtonClicked:(UISearchBar *)searchBar{[self doSearch:searchBar];}/*键盘搜索按钮*/- (void)searchBarSearchButtonClicked:(UISearchBar *)searchBar{[searchBar resignFirstResponder];[self doSearch:searchBar];}/*搜索*/- (void)doSearch:(UISearchBar *)searchBar{NSString *email = searchBar.text;...}

UISearchBar上按钮的默认文字为Cancel，如果想改为其他文字请调用一下代码：

for(id cc in [searchtext subviews]){   if([cc isKindOfClass:[UIButton class]]){       UIButton *btn = (UIButton *)cc;       [btn setTitle:@"Search"  forState:UIControlStateNormal];   }}
