iOS 中设置程序应用横竖屏设置

在***.plist中supported interface orientation选项中添加或者减少横竖屏属性，xml的话如下

<?xml version="1.0" encoding="UTF-8"?>

<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">
<plist version="1.0">
<array>
<string>UIInterfaceOrientationLandscapeLeft</string>
<string>UIInterfaceOrientationLandscapeRight</string>
</array>

</plist>

这里添加的代码是应用刚启动的时候的设置

在代码中添加

- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation
{
    // Return YES for supported orientations cgpvdbds
    //return YES; //YES 支持所有方向上的变动
    return (interfaceOrientation == UIInterfaceOrientationLandscapeLeft || interfaceOrientation == UIInterfaceOrientationLandscapeRight ); //设置为横屏，有两个方向，互相对称
}

以上的代码是竖屏的，如果要哥哥方向都行的话就添加四个方向

- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation
{
    // Return YES for supported orientations cgpvdbds
    //return YES; //YES 支持所有方向上的变动
    return  YES;
}

以上便是今日所学之心得，如果有什么不对的，望前辈指点

补充：

#pragma mark - 控制旋转

// after ios6

-(NSUInteger)supportedInterfaceOrientations{

    return UIInterfaceOrientationMaskLandscape;

}

- (BOOL)shouldAutorotate

{

    return  YES;

}

// before ios6 

- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation

{

    return UIInterfaceOrientationIsLandscape(interfaceOrientation);    

}

- (void)willRotateToInterfaceOrientation:(UIInterfaceOrientation)toInterfaceOrientation duration:(NSTimeInterval)duration {

    [NSObject cancelPreviousPerformRequestsWithTarget:self selector:@selector(hiddenControls) object:nil];

    [self hiddenControls];

}

-(void)didRotateFromInterfaceOrientation:(UIInterfaceOrientation)fromInterfaceOrientation {

    NSLog(@"rotate");

}
