本文介绍了一种通过重新布局按钮和切换视图来适应不同屏幕方向的方法。提供了两种方式：一种是在旋转过程中调整按钮位置；另一种是预先设计好两种视图（竖屏和横屏），在旋转时进行切换。

Two Ways

One, reconstruction of the view when rotation

//this function will Running after the start of rotation, the final automatically invoked before the occurrence of rotating animation - (void)willAnimateSecondHalfOfRotationFromInterfaceOrientation:(UIInterfaceOrientation)fromInterfaceOrientation duration:(NSTimeInterval)duration { UIInterfaceOrientation toInterfaceOrientation = self.interfaceOrientation; [UIView beginAnimations:@"move buttons" context:nil]; if (toInterfaceOrientation == UIInterfaceOrientationPortrait || toInterfaceOrientation == UIInterfaceOrientationPortraitUpsideDown) { button1.frame = CGRectMake(20, 20, 125, 125); button2.frame = CGRectMake(175, 20, 125, 125); button3.frame = CGRectMake(20, 168, 125, 125); button4.frame = CGRectMake(175, 168, 125, 125); button5.frame = CGRectMake(20, 315, 125, 125); button6.frame = CGRectMake(175, 315, 125, 125); } else { button1.frame = CGRectMake(20, 20, 125, 125); button2.frame = CGRectMake(20, 155, 125, 125); button3.frame = CGRectMake(177, 20, 125, 125); button4.frame = CGRectMake(177, 155, 125, 125); button5.frame = CGRectMake(328, 20, 125, 125); button6.frame = CGRectMake(328, 155, 125, 125); } [UIView commitAnimations]; }

The Other, design two view to show

#define degreesToRadian(x) (M_PI * (x) / 180.0) //all changes will completed before the occurrence of rotating animation //this function any designed for which changes would complete before the rotating animation all complete - (void)willAnimateFirstHalfOfRotationToInterfaceOrientation:(UIInterfaceOrientation)toInterfaceOrientation duration:(NSTimeInterval)duration { if (toInterfaceOrientation == UIInterfaceOrientationPortrait) { self.view = self.portrait; self.view.transform = CGAffineTransformIdentity; self.view.transform = CGAffineTransformMakeRotation(degreesToRadian(0)); //to build a rotation transformation(need framework CodeGraphicsframework) self.view.bounds = CGRectMake(0.0, 0.0, 300.0, 480.0); } else if (toInterfaceOrientation == UIInterfaceOrientationLandscapeLeft) { self.view = self.landscape; self.view.transform = CGAffineTransformIdentity; self.view.transform = CGAffineTransformMakeRotation(degreesToRadian(-90)); self.view.bounds = CGRectMake(0.0, 0.0, 460.0, 320.0); } else if (toInterfaceOrientation == UIInterfaceOrientationPortraitUpsideDown) { self.view = self.portrait; self.view.transform = CGAffineTransformIdentity; self.view.transform = CGAffineTransformMakeRotation(degreesToRadian(180)); self.view.bounds = CGRectMake(0.0, 0.0, 300.0, 480.0); } else if (toInterfaceOrientation == UIInterfaceOrientationLandscapeRight) { self.view = self.landscape; self.view.transform = CGAffineTransformIdentity; self.view.transform = CGAffineTransformMakeRotation(degreesToRadian(90)); self.view.bounds = CGRectMake(0.0, 0.0, 460.0, 320.0); } }
