重温自动旋转和自动调整大小

问题描述：

原来是这样子写的

    if (interfaceOrientation == UIInterfaceOrientationPortrait ||interfaceOrientation == UIInterfaceOrientationPortraitUpsideDown) {

        NSLog(@"myPortrait before:%@",myPortrait);

        DerictionV = 1;

        //        logonView.view  = logonView.portrait;

        self.view = myPortrait;

        scrollView_P.contentSize = CGSizeMake(scrollView_P.bounds.size.width, scrollView_P.bounds.size.height+200);

        NSLog(@"myPortrait after:%@",myPortrait);

    }

    else{

        NSLog(@"myLandscape before:%@",myLandscape);

        DerictionV = 0;

        //        logonView.view  = logonView.landscape;

        self.view = myLandscape;

        scrollView_L.contentSize = CGSizeMake(scrollView_L.bounds.size.width, scrollView_L.bounds.size.height+200);

        NSLog(@"myLandscape after:%@",myLandscape);

    }

记录了一下日志：

碰到个相关的问题，查阅了相关view的只是，无解，于是乎捡起旧书本，记录于此。

内部正方形，实线，自由改变宽度；虚线，竟可能原值。

四周的四个红色“I”。如果“I”是虚线，那么距离就是灵活可变的；如果“I”是红色实线，则间距的值应尽可能保持不变。

内部和外部是相反的，注意到没。略微有点忘了。平时都是看动画的。（这段跟整个问题无关，看书的时候看到，又有点忘了，顺便记录一下）

抄了书上的代码，就ok了。

    if (toInterfaceOrientation==UIInterfaceOrientationPortrait) {

        DerictionV = 1;

        self.view=self.myPortrait;

        self.view.transform=CGAffineTransformIdentity;

        self.view.transform=CGAffineTransformMakeRotation(degreesToRadians(0));

        self.view.bounds=CGRectMake(0.0, 0.0, 768.0, 1024.0);

        

    }

    if (toInterfaceOrientation==UIInterfaceOrientationLandscapeLeft) {

        DerictionV = 0;

        self.view=self.myLandscape;

        self.view.transform=CGAffineTransformMakeRotation(degreesToRadians(0));

        self.view.transform=CGAffineTransformMakeRotation(degreesToRadians(-90));

        self.view.bounds=CGRectMake(0.0, 0.0, 1024.0, 768.0);

    }

    if (toInterfaceOrientation==UIInterfaceOrientationPortraitUpsideDown) {

        DerictionV = 1;

        self.view=self.myPortrait;

        self.view.transform=CGAffineTransformMakeRotation(degreesToRadians(180));

        self.view.bounds=CGRectMake(0.0, 0.0, 768.0, 1024.0);

    }

    if (toInterfaceOrientation==UIInterfaceOrientationLandscapeRight) {

        DerictionV = 0;

        self.view=self.myLandscape;

        self.view.transform=CGAffineTransformMakeRotation(degreesToRadians(90));

        self.view.bounds=CGRectMake(0.0, 0.0, 1024.0, 768.0);

    }
