抱歉响应延迟,但我已经提取了我的代码,您可以看到我如何旋转我的设备以仅在横向中全屏显示“地图视图”。
-(void)willAnimateRotationToInterfaceOrientation:(UIInterfaceOrientation)toInterfaceOrientation duration:(NSTimeInterval)duration {
if(toInterfaceOrientation == UIInterfaceOrientationLandscapeRight || toInterfaceOrientation == UIInterfaceOrientationLandscapeLeft) {
[self hideTabBar:self.tabBarController];
[self.view bringSubviewToFront:self.eventsMapView];
self.eventsMapView.bounds = self.view.bounds;
self.eventsMapView.frame = CGRectMake(0, -208, self.view.frame.size.width, 300);
} else if(toInterfaceOrientation == UIInterfaceOrientationPortraitUpsideDown || toInterfaceOrientation == UIInterfaceOrientationPortrait) {
[self showTabBar:self.tabBarController];
[self.view sendSubviewToBack:self.eventsMapView];
}
}
由于我们调用其中的方法来实际隐藏和显示选项卡栏,因此我们还需要在 .m 文件中定义这些方法:
#pragma mark - Tab Bar Methods -
-(void)hideTabBar:(UITabBarController *)tabbarcontroller {
[UIView beginAnimations:nil context:NULL];
[UIView setAnimationDuration:0.3];
for(UIView *view in tabbarcontroller.view.subviews) {
if([view isKindOfClass:[UITabBar class]]) {
[view setFrame:CGRectMake(view.frame.origin.x, 480, view.frame.size.width, view.frame.size.height)];
} else {
[view setFrame:CGRectMake(view.frame.origin.x, view.frame.origin.y, view.frame.size.width, 480)];
}
}
[UIView commitAnimations];
}
-(void)showTabBar:(UITabBarController *)tabbarcontroller {
[UIView beginAnimations:nil context:NULL];
[UIView setAnimationDuration:0.3];
for(UIView *view in tabbarcontroller.view.subviews) {
if([view isKindOfClass:[UITabBar class]]) {
[view setFrame:CGRectMake(view.frame.origin.x, 431, view.frame.size.width, view.frame.size.height)];
} else {
[view setFrame:CGRectMake(view.frame.origin.x, view.frame.origin.y, view.frame.size.width, 431)];
}
}
[UIView commitAnimations];
}
如果您已经在选项卡栏控制器中,那么您需要确保每个子项(或单个选项卡 ViewController)都返回 TRUE,如下所示。
-(BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation {
return TRUE;
}
希望这会有所帮助 - 如果您有任何问题,请发表评论,我会更新我的答案以更好地展示它。
