我正在使用其中的TextField来完成与UISearchBar相同的外观,如我的iOS 6应用程序.我试图用几种方式编码,还没有成功.问题是,自从iOS 7以来,我无法以任何方式更改TextField的框架.结果是,我的TextField占用了NavigationBar中的所有空间,并覆盖了右边的UIBarButtonItem(菜单按钮).见下图：

iOS 6代码：这是我如何在iOS 6中编码,在那里我可以将TextFields框架设置为任何我喜欢的！
UITextField *sbTextField = (UITextField *)[searchBar.subviews lastObject]; [sbTextField removeFromSuperview]; CGRect rect = searchBar.frame; rect.size.height = 32; rect.size.width = 210; sbTextField.frame = rect; [sbTextField setAutoresizingMask:UIViewAutoresizingFlexibleBottomMargin]; UIBarButtonItem *searchBarNavigationItem = [[UIBarButtonItem alloc] initWithCustomView:sbTextField]; [[self navigationItem] setLeftBarButtonItem:searchBarNavigationItem];
iOS 7中的代码上面的结果：！[iOS 7 look]
iOS 7代码：iOS 7中的区别是,您需要使用subViews才能将UITextField添加到UISearchBar / UINavigationBar.通过这样做,我还没有改变它的框架.它目前正在与右边的menuButton重叠,该代码可以在下面的图片中看到…
UITextField* sbTextField;
CGRect rect = subView.frame;
rect.size.height = 32;
rect.size.width = 115;
for (UIView *subView in self.searchBar.subviews){
for (UIView *ndLeveSubView in subView.subviews){
if ([ndLeveSubView isKindOfClass:[UITextField class]])
{
sbTextField = (UITextField *)ndLeveSubView;
sbTextField.backgroundColor =[UIColor whiteColor];
UIBarButtonItem *searchBarNavigationItem = [[UIBarButtonItem alloc] initWithCustomView:sbTextField];
sbTextField.frame = rect;
self.navigationItem.leftBarButtonItem = searchBarNavigationItem;
self.navigationItem.rightBarButtonItem = menuButton;
[sbTextField removeFromSuperview];
break;
}
}
}
[self.searchBar reloadInputViews];
SO …是否可以以任何方式更改子视图的框架(TextField)？ 原文链接：https://www.f2er.com/iOS/336722.html
