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

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;
}

只需将以下代码放入 -(void) ViewDidLoad。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，在其实现中添加如下内容： - (void)setActive:(BOOL)visible animated:(BOOL)animated { [super setActive:visible animated:animated]; [self.searchContentsController.navigationController setNavigationBarHidden：NO动画：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 = 框架；框架 = self.searchBar.frame; self.searchBar.frame = 框架； [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;

您可以从这里了解更多信息：UISearchController and definesPresentationContext

并来自 Apple 文档：UISearchController documentation

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

-(void)searchDisplayControllerWillBeginSearch:(UISearchDisplayController *)controller {
    if ([[[UIDevice currentDevice] systemVersion] floatValue] >= 7.0) {
        CGRect statusBarFrame =  [[UIApplication sharedApplication] statusBarFrame];
        CGRect frame = controller.searchBar.frame;
        frame.origin.y += statusBarFrame.size.height;
        controller.searchBar.frame = frame;
    }
}

-(void)searchDisplayControllerWillEndSearch:(UISearchDisplayController *)controller {
    if ([[[UIDevice currentDevice] systemVersion] floatValue] >= 7.0) {
        CGRect statusBarFrame =  [[UIApplication sharedApplication] statusBarFrame];
        CGRect frame = controller.searchBar.frame;
        frame.origin.y -= statusBarFrame.size.height;
        controller.searchBar.frame = frame;
    }
}

仅当您的导航栏未隐藏时，上述答案才有效。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)];

    }
}

基于这篇文章：UISearchBar overlaps status bar in iOS

将已添加到 UIViewController/UITablewViewController 的 SearchDisplayController 子类化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];
    }
}
