方法一：自動布局

1.將項目中界面的四種手持方式都點上；

2.取消Use Autolayout;

3.選擇界面中某個控件然后到屬性工具欄中去找到AutoSizing功能，勾選對應(yīng)的絕對定位的線條

4.重寫可以旋轉(zhuǎn)的方法

-(BOOL)shouldAutorotate {     return YES; } -(NSUInteger)supportedInterfaceOrientations {     return UIInterfaceOrientationMaskAll; } 

方法二：手動布局一（通過代碼改view種控件的坐標）

1.重寫可以旋轉(zhuǎn)的方法

-(BOOL)shouldAutorotate {     return YES; } -(NSUInteger)supportedInterfaceOrientations {     return UIInterfaceOrientationMaskAll; } 

2.勾選上項目中支持的四種手持類型

3.取消Use Autolayout

4.代碼實現(xiàn)：

//每當屏幕旋轉(zhuǎn)的時候都會觸發(fā)一個 -(void)willAnimateRotationToInterfaceOrientation:(UIInterfaceOrientation)toInterfaceOrientation duration:(NSTimeInterval)duration {     //如果是是橫屏狀態(tài)     if(toInterfaceOrientation == UIInterfaceOrientationLandscapeLeft )     {         self.l1.frame = CGRectMake(20, 25, 110, 110);         self.l2.frame = CGRectMake(162, 25, 110, 110);         self.l3.frame = CGRectMake(304, 25, 110, 110);         self.r1.frame = CGRectMake(20, 178, 110, 110);         self.r2.frame = CGRectMake(162, 178, 110, 110);         self.r3.frame = CGRectMake(304, 178, 110, 110);} }

方法三：手動布局二（在xib中新建一個支持橫屏的view通過雙view切換實現(xiàn)）

1.在xib文件中拖一個view控件，選擇Orientation屬性為橫屏

2.布局好界面

3.將橫縱view分別在controller.h文件中創(chuàng)建對應(yīng)的屬性，命名為

@property (retain, nonatomic)IBOutletUIView *landspaceView;

@property (retain, nonatomic)IBOutletUIView *portatiorView;

4.代碼實現(xiàn)

宏定義實現(xiàn)角度轉(zhuǎn)弧度

#define degreesToRadia(x) (M_PI * (x) / 180)//參數(shù)要加括號 ，尤其是參數(shù)附近特別要加括號

-(BOOL)shouldAutorotate {     return YES; } -(NSUInteger)supportedInterfaceOrientations {     return UIInterfaceOrientationMaskAll; } //每當屏幕旋轉(zhuǎn)的時候都會觸發(fā)一個 -(void)willAnimateRotationToInterfaceOrientation:(UIInterfaceOrientation)toInterfaceOrientation duration:(NSTimeInterval)duration {     //如果是是橫屏狀態(tài)     if(toInterfaceOrientation == UIInterfaceOrientationLandscapeLeft )     { //        self.l1.frame = CGRectMake(20, 25, 110, 110); //        self.l2.frame = CGRectMake(162, 25, 110, 110); //        self.l3.frame = CGRectMake(304, 25, 110, 110); //        self.r1.frame = CGRectMake(20, 178, 110, 110); //        self.r2.frame = CGRectMake(162, 178, 110, 110); //        self.r3.frame = CGRectMake(304, 178, 110, 110);         self.view = self.landspaceView;         //self.view.transform = CGAffineTransformIdentity;         self.view.transform = CGAffineTransformMakeRotation(degreesToRadia(270));         self.view.bounds = CGRectMake(0, 0, 480, 300);     }     else if(toInterfaceOrientation == UIInterfaceOrientationLandscapeRight)     { //        self.l1.frame = CGRectMake(37, 20, 110, 110); //        self.l2.frame = CGRectMake(37, 162, 110, 110); //        self.l3.frame = CGRectMake(37, 304, 110, 110); //        self.r1.frame = CGRectMake(190, 20, 110, 110); //        self.r2.frame = CGRectMake(190, 162, 110, 110); //        self.r3.frame = CGRectMake(190, 304, 110, 110);         self.view = self.landspaceView;         //self.view.transform = CGAffineTransformIdentity;         self.view.transform = CGAffineTransformMakeRotation(degreesToRadia(90));         self.view.bounds = CGRectMake(0, 0, 480, 300);     }     else if (toInterfaceOrientation == UIInterfaceOrientationPortrait)     {         self.view = self.portatiorView;         self.view.transform = CGAffineTransformIdentity;         self.view.bounds = CGRectMake(0, 0, 320, 460);     }     else if(toInterfaceOrientation == UIInterfaceOrientationPortraitUpsideDown)     {         self.view = self.portatiorView;         //self.view = self.landspaceView;         //self.view.transform = CGAffineTransformIdentity;         self.view.transform = CGAffineTransformMakeRotation(degreesToRadia(180));         self.view.bounds = CGRectMake(0, 0, 320, 460);     } }
