查看方向更改 [英] View Orientation changes

问题描述

更新：我发现为什么它一直在加载相同的视图。我现在解决了这个问题这是一个错字

Update: I found why it was loading the same view the whole time. I now fixed that. It was a typo

ControllerForSplitViews.m

ControllerForSplitViews.m

- (id)init
{
    self = [super initWithNibName:@"ControllerForSplitViews" bundle:nil];
    if(UIInterfaceOrientationIsLandscape(self.interfaceOrientation)){
        self.view = landscapeView;
    }
    if(UIInterfaceOrientationIsPortrait(self.interfaceOrientation)){
        self.view = portraintView;
    }
    [[UIDevice currentDevice] beginGeneratingDeviceOrientationNotifications];
    [[NSNotificationCenter defaultCenter] addObserver:self     selector:@selector(orientationChanged:) name:@"UIDeviceOrientationDidChangeNotification" object:nil];
    return self;
}

这样做。

现在问题。加载并运行视图时，我更改方向并从同一个nib文件加载不同的视图，修复：但是一旦我这样做，其他UI元素就会消失，只保留我的横向视图的ui元素，当我再次旋转设备它不会再次加载我的纵向视图？有任何建议可能会发生这种情况吗？

Now the problem. When the view is loaded and running I change the orientation and load a different view from the same nib file, Fixed: but as soon as I do this the other UI elements disappears and only the ui elements of my landscape view is kept and when I rotate the device again it doesn't load my portrait view again? Any suggestions why this might happen?

-(void) orientationChanged:(id)object
{   
    if(UIInterfaceOrientationIsPortrait(self.interfaceOrientation))
    {
        self.view = portraintView;
    }
    if(UIInterfaceOrientationIsLandscape(self.interfaceOrientation))
    {
        self.view = landscapeView;
    }
 }

新问题，每次更改加载的方向相反方向的视图

New Problem, each time I change the orientation it loads the opposite orientation's view

谢谢

推荐答案

好的我找到了修复它有效，但我不知道为什么我的原始代码不能正常工作：

Ok so I found a fix that works, but I have no idea why my original code didn't work what I did was:

删除：

[[UIDevice currentDevice] beginGeneratingDeviceOrientationNotifications];
[[NSNotificationCenter defaultCenter] addObserver:self     selector:@selector(orientationChanged:) name:@"UIDeviceOrientationDidChangeNotification" object:nil];

删除：

-(void) orientationChanged:(id)object
{   
    if(UIInterfaceOrientationIsPortrait(self.interfaceOrientation))
    {
        self.view = portraintView;
    }
    if(UIInterfaceOrientationIsLandscape(self.interfaceOrientation))
    {
        self.view = landscapeView;
    }
 }

更改：

- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation 
{
    if(((interfaceOrientation == UIInterfaceOrientationLandscapeLeft) || 
    (interfaceOrientation == UIInterfaceOrientationLandscapeRight))){

        self.view = landscapeView;

    }else if(((interfaceOrientation == UIInterfaceOrientationPortrait) || 
          (interfaceOrientation == UIInterfaceOrientationPortraitUpsideDown))){

        self.view = portraintView;

    }
    return YES;
}

现在它完美运作
