Question

我想让UIView坐在状态栏的顶部，但目前没有成功。我尝试过以下方法：

view.window?.windowLevel = UIWindowLevelStatusBar + 1 // view being a UIView() object

我也尝试过：

let win: UIWindow = UIWindow( )
win.frame = CGRect( x: 0, y: 0, width: 100, height: Display.height )
win.windowLevel = UIWindowLevelStatusBar + 1
win.hidden = false
win.backgroundColor = UIColor.blueColor()
win.makeKeyAndVisible()

在所有情况下，状态栏仍位于顶部。有人有这个在Swift工作吗？

这是我的简单解决方案（你也可以使用MTStatusBarOverlay - 检查git hub）。

首先初始化窗口。在主窗口上设置makeKeyAndVisible后执行此操作。

  self.syncMessageWindow = [[UIWindow alloc] initWithFrame:messageRect];
  self.syncMessageWindow.clipsToBounds = YES;
  self.syncMessageWindow.frame = messageRect;
  self.syncMessageWindow.windowLevel = UIWindowLevelStatusBar+1.f;
  self.syncMessageWindow.alpha = 1.f;

  self.syncMessageView = [[UIView alloc] initWithFrame:messageRect];
  UILabel *label = [[UILabel alloc] initWithFrame:CGRectMake(10, 2, messageRect.size.width-20, 16)];
  [label setTag:100];
  [label setTextAlignment:NSTextAlignmentCenter];
  [label setFont:[UIFont fontWithName:@"HelveticaNeue" size:12.0]];
  [label setTextColor:[UIColor whiteColor]];
  [self.syncMessageView addSubview:label];
  [self.syncMessageWindow addSubview:self.syncMessageView];
  [self.syncMessageWindow setRootViewController:[UIApplication sharedApplication].delegate.window.rootViewController];
  [self.syncMessageWindow makeKeyAndVisible];
  self.syncMessageWindow.hidden = YES;

显示消息

if(self.syncMessageWindow.hidden == YES) {
self.syncMessageWindow.hidden = NO;
[self.syncMessageView setBackgroundColor:color];
[self.syncMessageView setAlpha:1.0];
[self.syncMessageView setFrame:CGRectMake(0, -20, self.syncMessageView.frame.size.width, self.syncMessageView.frame.size.height)];
[self.syncMessageWindow setWindowLevel:UIWindowLevelStatusBar+1];
[((UILabel*)[self.syncMessageView viewWithTag:100]) setText:message];
[UIView animateWithDuration:.3 delay:0.0 options:UIViewAnimationOptionCurveEaseIn animations:^{
  self.syncMessageView.frame = CGRectMake(0, 0, self.syncMessageView.frame.size.width, self.syncMessageView.frame.size.height);
} completion:^(BOOL finished) {
  [UIView animateWithDuration:.3 delay:2.0 options:UIViewAnimationOptionCurveEaseIn animations:^{
    self.syncMessageView.frame = CGRectMake(0, -20, self.syncMessageView.frame.size.width, self.syncMessageView.frame.size.height);
  } completion:^(BOOL finished) {
    [self.syncMessageWindow setWindowLevel:UIWindowLevelNormal];
    self.syncMessageWindow.hidden = YES;
  }];

}];

}

为什么不隐藏状态栏？然后你可以把视图放在顶部。请参阅How to hide iOS status bar。

我认为可以用另一个视图覆盖状态栏，因为默认情况下所有内容都位于状态栏后面。

将UIView置于状态栏上方
