ios - iOS 7 UISearchDisplayController 搜索栏在搜索时与状态栏重叠

Question

我正在为 iOS 7 更新我的应用程序，并且我正在调整我的所有视图以考虑新的透明状态栏（我的应用程序仍将使用不透明的导航栏）。

在每个视图中调整状态栏相对容易，除了我在一个视图控制器中将 UISearchBar 连接到 UISearchDisplayController 时遇到的一个主要问题。

搜索栏似乎正常显示，如下图：

问题是，一旦我开始搜索，导航栏就会消失（应该如此），但其他所有内容也会向上移动以与状态栏重叠：

这似乎没有按预期工作，因为屏幕变暗发生在搜索栏下方 20 像素处，搜索栏应在此处结束。

iOS 7 中是否有内置解决方案？我宁愿不必在每次用户开始和结束搜索时手动调整每个视图的框架。

谢谢！

将以下行放入 viewDidLoad 为我修复它：

self.edgesForExtendedLayout = UIRectEdgeNone;

感谢 hodade 带领我走上正轨！您的解决方案有效，只是它只移动了搜索栏的框架，将我的其他子视图留在了错误的位置。我唯一改变的是移动视图中的所有子视图，并为其设置动画。

谢谢！

-(void)searchDisplayControllerWillBeginSearch:(UISearchDisplayController *)controller {
    if ([[[UIDevice currentDevice] systemVersion] floatValue] >= 7.0) {
        CGRect statusBarFrame =  [[UIApplication sharedApplication] statusBarFrame];
        [UIView animateWithDuration:0.25 animations:^{
            for (UIView *subview in self.view.subviews)
                subview.transform = CGAffineTransformMakeTranslation(0, statusBarFrame.size.height);
        }];
    }
}

-(void)searchDisplayControllerWillEndSearch:(UISearchDisplayController *)controller {
    if ([[[UIDevice currentDevice] systemVersion] floatValue] >= 7.0) {
        [UIView animateWithDuration:0.25 animations:^{
            for (UIView *subview in self.view.subviews)
                subview.transform = CGAffineTransformIdentity;
        }];
    }
}

你可能没有使用半透明的导航栏？如果是这样，这将解决它。

- (void)searchDisplayControllerWillBeginSearch:(UISearchDisplayController *)controller {
    self.navigationController.navigationBar.translucent = YES;
}

- (void)searchDisplayControllerDidEndSearch:(UISearchDisplayController *)controller {
    self.navigationController.navigationBar.translucent = NO;
}

只需将以下代码放在-(void) ViewDidLoad中。它适用于 iOS 7 及更高版本

if (floor(NSFoundationVersionNumber) > NSFoundationVersionNumber_iOS_6_1) {
    self.edgesForExtendedLayout = UIRectEdgeNone;
}

更新：

if(SYSTEM_VERSION_GREATER_THAN(@"6.1")) {
    self.edgesForExtendedLayout = UIRectEdgeNone;
}

我做了下面的代码来解决这个问题。

    - (void) viewDidLayoutSubviews
{
         if(floor(NSFoundationVersionNumber) > NSFoundationVersionNumber_iOS_6_1)
        {
            CGRect viewBounds = self.view.bounds;
            CGFloat topBarOffset = self.topLayoutGuide.length;
            viewBounds.origin.y = topBarOffset * -1;
            self.view.bounds = viewBounds;
        }
}

这似乎描述了我遇到的问题；希望它会帮助我以前的职位。

将已添加到 UIViewController/UITablewViewController 的 SearchDisplayController 子类化，

在其实现中添加类似这样的内容：

 - (void)setActive:(BOOL)visible animated:(BOOL)animated
{
    [super setActive:visible animated:animated];

    [self.searchContentsController.navigationController setNavigationBarHidden: NO animated: NO];

    CGRect frame = self.searchResultsTableView.frame;
    frame.origin.y = CGRectGetHeight(self.searchContentsController.navigationController.navigationBar.frame);

    frame.size.height = CGRectGetHeight(frame) - CGRectGetMinY(frame);

    self.searchResultsTableView.frame = frame;

    frame = self.searchBar.frame;
    self.searchBar.frame = frame;

    [self.searchContentsController.view insertSubview:self.searchBar aboveSubview:self.searchResultsTableView];

}

我认为也许将其添加到 viewDidLoad 会有所帮助：

if([self respondsToSelector:@selector(setEdgesForExtendedLayout:)])
{
    self.edgesForExtendedLayout = UIRectEdgeNone;

}

只需添加

self.definesPresentationContext = YES;

您可以从这里阅读更多内容：UISearchController 和定义PresentationContext

并来自 Apple 文档：UISearchController 文档

注意： UISearchDispalyController 在 iOS7 中已弃用，在 iOS8 中使用 UISearchController 代替，上面的方法使用 UISearchController

就我而言，搜索栏下方的视图位于正确的位置，只有搜索栏与状态栏重叠。在这种情况下，这种代码的和平工作正常：

- (void)searchDisplayControllerWillBeginSearch:(UISearchDisplayController *)controller {        
    if (SYSTEM_VERSION_GREATER_THAN_OR_EQUAL_TO(@"7.0")) {
        CGRect statusBarFrame =  [[UIApplication sharedApplication] statusBarFrame];
        CGRect frame = self.searchBar.frame;
        frame.origin.y += statusBarFrame.size.height;
        self.searchBar.frame = frame;
    }
}

- (void)searchDisplayControllerWillEndSearch:(UISearchDisplayController *)controller {
    if (SYSTEM_VERSION_GREATER_THAN_OR_EQUAL_TO(@"7.0")) {
        CGRect statusBarFrame =  [[UIApplication sharedApplication] statusBarFrame];
        CGRect frame = self.searchBar.frame;
        frame.origin.y -= statusBarFrame.size.height;
        self.searchBar.frame = frame;
    }
}

希望对其他人有用

上述答案仅在您未隐藏导航栏时才有效。如果您隐藏了导航栏，请尝试以下操作：

-(void)viewDidAppear:(BOOL)animated{
if ([[[UIDevice currentDevice] systemVersion] floatValue] >= 7.0) {
    CGRect statusBarFrame =  [[UIApplication sharedApplication] statusBarFrame];
    [self.tableView setFrame:CGRectMake(self.tableView.frame.origin.x, self.tableView.frame.origin.y+statusBarFrame.size.height, self.tableView.frame.size.width, self.tableView.frame.size.height)];

    }
}

SearchDisplayController将已添加到您的您的子类化UIViewController/UITablewViewController并将其添加到其实现中-

- (void)setActive:(BOOL)visible animated:(BOOL)animated
{
    if(self.active == visible) return;
    [self.searchContentsController.navigationController setNavigationBarHidden:YES animated:NO];
    [super setActive:visible animated:animated];
    [self.searchContentsController.navigationController setNavigationBarHidden:NO animated:NO];
    if (visible) {
        [self.searchBar becomeFirstResponder];
    } else {
        [self.searchBar resignFirstResponder];
    }
}
