自定義頂部搜尋欄的清除按鈕圖示

一個方法即可解決:searchbar調用對象方法

[_searchBar setImage:[UIImage imageNamed:@"home_search_delete"] forSearchBarIcon:UISearchBarIconClear state:UIControlStateNormal];

為了確定clearbutton顯示,還可以先取出searchbar的textfield,然後設定其clearbutton樣式:

UITextField * searchField = [_searchBar valueForKey:@"_searchField"];

searchField.rightViewMode = UITextFieldViewModeWhileEditing;
