在表格视图中重新排列对象以适应iPad的不同方向

Question

我有一个由行填充的表，每行都包含图像、标题和按钮
当用户改变iPad的方向时，按钮应根据iPad的方向重新排列。请告诉我如何在uitableview单元格中重新排列对象
提前谢谢。

Answer 1

这将起作用：

-(void)viewWillAppear:(BOOL)animated
{
[[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(receivedRotate:) name:UIDeviceOrientationDidChangeNotification object:nil];
[[UIDevice currentDevice] beginGeneratingDeviceOrientationNotifications];
}
-(void)viewWillDisappear:(BOOL)animated
{
[[NSNotificationCenter defaultCenter] removeObserver:self name:UIDeviceOrientationDidChangeNotification object:nil];
}  

现在实现以下方法：

-(void)checkOrientation
{
UIDeviceOrientation orientation = [[UIDevice currentDevice] orientation];
    if (orientation == UIDeviceOrientationLandscapeLeft||orientation==UIDeviceOrientationLandscapeRight)
    {
        [tblView reloadData];
        // Set x coorinate of views you want to change
    }
    else
    {
        [tblView reloadData];
        // Set x coordinates of views to initial x xoordinates.
    }
}  

创建接收日期：

- (void)receivedRotate:(NSNotification *)notification
{    
[self checkOrientation];
}  

在viewDidLoad中：

-(void)viewDidLoad
{  
[self checkOrientation];
}
