更改UISearchBar button属性

标签：io   ar   for   sp   on   bs   as   tt   ui   

//点击搜索框时触发

- (BOOL)searchBarShouldBeginEditing:(UISearchBar *)searchBar

{

    self.theSearchUserSearchBar.showsCancelButton = YES; //很关键

    UIView *topView = self.theSearchUserSearchBar.subviews[0];

    for (UIView *searchbuttons in topView.subviews)

    {

        if ([searchbuttons isKindOfClass:NSClassFromString(@"UINavigationButton")])//NSClassFromString(@"UINavigationButton")

        {

            UIButton *cancelButton = (UIButton*)searchbuttons;

            cancelButton.enabled = YES;

            [cancelButton setTitle:@"确定" forState:UIControlStateNormal];

            break;

        }

    }

    return YES;

}

所以，同理可以更改 UISearchBar上面的任意view。
