我在this post中遇到了同样的问题,我遵循了所有建议的答案,但注意到工作,在我的情况下区别在于我有一个表视图控制器。
我已经尝试过很多方法来防止这种情况发生。
示例:
-(void)viewDidLayoutSubviews {
//the next 2 lines was tested with self.tableView and self.view
[self.view.topAnchor constraintEqualToAnchor:self.topLayoutGuide.bottomAnchor constant:8.0].active = YES;
[self.view constraintEqualToAnchor:[self.topLayoutGuide bottomAnchor]].active = YES;
[self.tableView setContentInset:UIEdgeInsetsMake(self.topLayoutGuide.length, 0, 0, 0)];
self.automaticallyAdjustsScrollViewInsets = YES;
}
内部viewDidLoad
:
self.navigationController.navigationBar.translucent = NO;
if ([self respondsToSelector:@selector(edgesForExtendedLayout)])
self.edgesForExtendedLayout = UIRectEdgeNone;
这是我的UITableViewController
配置:
这正是我的问题:
感谢您的帮助。

您是否尝试过在视图控制器中导航栏外观下禁用? 在你的init中添加以下内容:
self.edgesForExtendedLayout = UIRectEdgeNone;
self.extendedLayoutIncludesOpaqueBars = NO;
self.automaticallyAdjustsScrollViewInsets = NO;
我使用了Masonry AutoLayout库来设置约束并使用了以下代码段:
[_collectionView mas_makeConstraints:^(MASConstraintMaker *make) {
make.left.equalTo(self.view.mas_left);
make.top.equalTo(self.view.mas_top);
make.right.equalTo(self.view.mas_right);
}];
[_collectionView.bottomAnchor constraintEqualToAnchor:[self.bottomLayoutGuide bottomAnchor]].active = YES;

您可以对视图使用约束。
为紧凑视图设置顶部视图约束,如:
@property (weak, nonatomic) IBOutlet NSLayoutConstraint *searchViewTopConstraints;
在presentRecentsViewControllerFor:
中更新紧凑和扩展视图的约束-(void)presentRecentsViewControllerFor:(MSConversation*)conversation withPresentStyle:(MSMessagesAppPresentationStyle)presentationStyle
{
tableViewC = [[UIStoryboard storyboardWithName:@"MainInterface" bundle:nil] instantiateViewControllerWithIdentifier:@"ShareRecents"];
if (presentationStyle == MSMessagesAppPresentationStyleCompact) {
NSLog(@"Compact view");
tableViewC.searchViewTopConstraints.constant = 0;
} else
{
NSLog(@"Expanded view");
[self.view.topAnchor constraintEqualToAnchor:[self.topLayoutGuide bottomAnchor]].active = YES;
}
}
