ios - 在横向模式下添加 UIView

Question

我需要在我的 iOS 中添加广告功能应用程序。广告屏幕会在一段时间后出现。我的整体仅处于横向模式。当我尝试在当前 View 上添加 View 时，它会以纵向模式而不是横向模式显示 View 。我已经设置了 View 框架，即 CGSizeMake(0,0, 568, 320)

  time = [NSTimer scheduledTimerWithTimeInterval:2.0f 
                                          target:self 
                                        selector:@selector(showfirstad) 
                                        userInfo:nil 
                                         repeats:YES];
-(void)showfirstad {
   [[[[UIApplication sharedApplication] windows] lastObject] addSubview:firstad];
}

看起来像这样 .

Answer 1

_window = [UIApplication sharedApplication].keyWindow;
if (!_window) _window = [[UIApplication sharedApplication].windows objectAtIndex:0];

UIInterfaceOrientation orientation = self.window.rootViewController.interfaceOrientation;
// Set appropriate view frame (it won't be autosized by addSubview:)
CGRect appFrame = [[UIScreen mainScreen] applicationFrame];

if (UIInterfaceOrientationIsLandscape(orientation))
{
    // Need to flip the X-Y coordinates for landscape
    self.view_login.frame = CGRectMake(appFrame.origin.y, appFrame.origin.x, appFrame.size.height, appFrame.size.width+20);
else
{
    self.view_login.frame = appFrame;
}


[[[_window subviews] objectAtIndex:0] addSubview:self.view_login];
