iphone - LandScape/Portrait 尺寸不同 iOS

Question

我有五个 UIButton，我需要设置 UIButton 的框架，使其适合 Landscape 和肖像 不同的大小。 但是从下面的代码 viewDidLoad 加载正常但问题是加载堆栈后当我移动到 Landscape 到 portrait 或 portrait 到 Landscape 它应该根据我设置的 viewdidload 大小进行更改..但这并没有发生...它重叠为previous 按钮已经创建....我需要做哪些更改以便在更改 View 时..按钮应该正确显示..不应重叠。

-(void)viewDidLoad{
 int Height = 200;
    int Yposition = 20;
    for (int k=0; k<5; k++)
    {
 if ([UIApplication sharedApplication].statusBarOrientation== UIInterfaceOrientationLandscapeLeft || [UIApplication sharedApplication].statusBarOrientation  == UIInterfaceOrientationLandscapeRight) {

        UIButton *loPlayButton=[UIButton buttonWithType:UIButtonTypeCustom];
        [loPlayButton addTarget:self action:@selector(PlayButtonAction:) forControlEvents:UIControlEventTouchUpInside];
            //   loPlayButton.tag  = 100+k;
        NSLog(@"tag is %i",loPlayButton.tag);
        loPlayButton.alpha = 1.0;

        UIImage *image=[UIImage imageNamed:@"vid.png"];
        [loPlayButton setBackgroundImage:image forState:UIControlStateNormal];
        loPlayButton.frame=CGRectMake(520, Yposition +(k*Height +170), image.size.width, 30);
        // loPlayButton.tag=3;


        [mScrollView_por addSubview:loPlayButton];
        [mPlayButtonsArray addObject:loPlayButton];
             }



        if ([UIDevice currentDevice].orientation==UIInterfaceOrientationPortrait || [UIDevice currentDevice].orientation == UIInterfaceOrientationPortraitUpsideDown) {


            UIButton *loPlayButton=[UIButton buttonWithType:UIButtonTypeCustom];
            [loPlayButton addTarget:self action:@selector(PlayButtonAction:) forControlEvents:UIControlEventTouchUpInside];
                //   loPlayButton.tag  = 100+k;
            NSLog(@"tag is %i",loPlayButton.tag);
            loPlayButton.alpha = 1.0;

            UIImage *image=[UIImage imageNamed:@"vid.png"];
            [loPlayButton setBackgroundImage:image forState:UIControlStateNormal];
            loPlayButton.frame=CGRectMake(440, Yposition +(k*Height +170), image.size.width, 30);
                // loPlayButton.tag=3;


            [mScrollView_por addSubview:loPlayButton];
            [mPlayButtonsArray addObject:loPlayButton];

        }}}
