关于iOS6.0 屏幕旋转的问题

来源：未知责任编辑：智问网络发表时间:2013-11-12 17:14　点击:次

1、首先在appDelegate中，把view添加到window中有两种方式、

[cpp]
self.window.rootViewController = self.view;
[self.window addSubview:self.view.view];

self.window.rootViewController = self.view;
[self.window addSubview:self.view.view];
但是如果用第二种的话，在ios6.0中再去设置屏幕旋转是没有任何效果的，必须使用第一种。在ios6.0以前的版本是没有这种分别的。

2、开启全部方向屏幕旋转的方式

iOS6.0之前：只需这个方法返回yes即可

[cpp] www.2cto.com
- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)toInterfaceOrientation
{
return YES;
}

    - (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)toInterfaceOrientation
    {
    return YES;
    }   iOS6.0中需要这三个方法一起使用才可以

[cpp]
- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)toInterfaceOrientation
{
    return (toInterfaceOrientation != UIInterfaceOrientationMaskPortraitUpsideDown);
}
- (BOOL)shouldAutorotate
{
    return YES;
}
- (NSUInteger)supportedInterfaceOrientations
{
    return UIInterfaceOrientationMaskAllButUpsideDown;
}

    - (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)toInterfaceOrientation
    {
    return (toInterfaceOrientation != UIInterfaceOrientationMaskPortraitUpsideDown);
    }
    - (BOOL)shouldAutorotate
    {
    return YES;
    }
    - (NSUInteger)supportedInterfaceOrientations
    {
    return UIInterfaceOrientationMaskAllButUpsideDown;
    }当然了关闭全部方向屏幕旋转的方式则把上面的返回值改为no即可

iOS6.0之前：

[cpp]
- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)toInterfaceOrientation
{
return NO;
}

    - (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)toInterfaceOrientation
    {
    return NO;
    }   iOS6.0中

[cpp]
- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)toInterfaceOrientation
{
return (toInterfaceOrientation == UIInterfaceOrientationPortrait);
}
- (BOOL)shouldAutorotate
{
return NO;
}
- (NSUInteger)supportedInterfaceOrientations
{
return UIInterfaceOrientationMaskPortrait;//只支持这一个方向(正常的方向)
}

    - (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)toInterfaceOrientation
    {
   return (toInterfaceOrientation == UIInterfaceOrientationPortrait);
    }
    - (BOOL)shouldAutorotate
    {
   return NO;
    }
    - (NSUInteger)supportedInterfaceOrientations
    {
        return UIInterfaceOrientationMaskPortrait;//只支持这一个方向(正常的方向)
    }

使用屏幕旋转常用的方法

[cpp]
//视图旋转之前自动调用
-(void)willRotateToInterfaceOrientation:(UIInterfaceOrientation)toInterfaceOrientation duration:(NSTimeInterval)duration {
    NSLog(@"视图旋转之前自动调用");
}
//视图旋转方向发生改变时会自动调用
-(void)willAnimateRotationToInterfaceOrientation:(UIInterfaceOrientation)toInterfaceOrientation duration:(NSTimeInterval)duration
{
    NSLog(@"视图旋转方向发生改变时会自动调用");
}
//视图旋转完成之后会自动调用

-(void)didRotateFromInterfaceOrientation:(UIInterfaceOrientation)fromInterfaceOrientation {
    NSLog(@"视图旋转完成之后自动调用");
}

//视图旋转之前自动调用
-(void)willRotateToInterfaceOrientation:(UIInterfaceOrientation)toInterfaceOrientation duration:(NSTimeInterval)duration {
NSLog(@"视图旋转之前自动调用");
}
//视图旋转方向发生改变时会自动调用
-(void)willAnimateRotationToInterfaceOrientation:(UIInterfaceOrientation)toInterfaceOrientation duration:(NSTimeInterval)duration
{
NSLog(@"视图旋转方向发生改变时会自动调用");
}
//视图旋转完成之后会自动调用

-(void)didRotateFromInterfaceOrientation:(UIInterfaceOrientation)fromInterfaceOrientation {
NSLog(@"视图旋转完成之后自动调用");
}
