heightForRowAtIndexPath无法识别方向

Question

我有一个tableView，我必须根据设备是纵向还是横向来定义不同的单元高度，但这种方法似乎无法识别设备的方向。此方法不起作用：

  -(CGFloat) tableView:(UITableView *)tableView heightForRowAtIndexPath:(NSIndexPath *)indexPath{


  UIDeviceOrientation deviceOrientation = [[UIDevice currentDevice]orientation];//here doesn't recognize the orientation


 if(UI_USER_INTERFACE_IDIOM()== UIUserInterfaceIdiomPhone){
     if(deviceOrientation == UIInterfaceOrientationPortrait || deviceOrientation== UIInterfaceOrientationPortraitUpsideDown) {
         self.tableView.rowHeight =33.33333;

     }
     else if (deviceOrientation== UIInterfaceOrientationLandscapeRight || deviceOrientation==UIInterfaceOrientationLandscapeLeft){

         self.tableView.rowHeight = 16.333333;
     }
 }

 else {
     if(deviceOrientation == UIInterfaceOrientationPortrait || deviceOrientation== UIInterfaceOrientationPortraitUpsideDown){
         self.tableView.rowHeight = 66.66666;

     }else if (deviceOrientation== UIInterfaceOrientationLandscapeRight || deviceOrientation==UIInterfaceOrientationLandscapeLeft){
         self.tableView.rowHeight = 33.333333;

     }

 }
 return self.tableView.rowHeight;

}

Answer 1

使用：

UIDeviceOrientation deviceOrientation = [UIApplication sharedApplication].statusBarOrientation;

要识别statusBar方向，请执行以下操作：

UIDeviceOrientation deviceOrientation = [[UIDevice currentDevice]orientation];

Answer 2

使用单例类方法UIDeviceOrientation deviceOrientation = UIApplication sharedApplication.statusBarOrientation]；
