iOS UISearchBar 获取 cancelButton，UItextField

获取CancelButton，代码以下：

for (UIView *view in [[_searchBar.subviews lastObject] subviews]) {

        if ([view isKindOfClass:[UIButton class]]) {

            UIButton *cancelBtn = (UIButton *)view；            

            NSAttributedString *str2 = [[NSAttributedString alloc] initWithString:@"取消" attributes:@{NSFontAttributeName:[UIFont systemFontOfSize:15],NSForegroundColorAttributeName:COLORWITH_RGB(82, 158, 204)}];            

            [cancelBtn setAttributedTitle:str2 forState:UIControlStateNormal];

        }

    }

 

获取UItextfiled，代码以下：

for (UIView *view in [[_searchBar.subviews lastObject] subviews]){

        if ([view isKindOfClass:[UITextField class]]) {

            UITextField *textFiled = (UITextField*)view;

        }

    }

虽然获取到了试图，但有一些属性无法设置，只能对一些进行处理
