02 買粉絲買粉絲獲取位置失敗ios(為什么iOS 10 下無法自動獲取精確定位)

//用于切換的兩個View

IBOutlet UIView *landscape;

IBOutlet UIView *portrait;

//Foo兩個View中的Foo按鈕

IBOutlet UIButton *landscapeFooButton;

IBOutlet UIButton *portraitFooButton;

//Bar兩個View中的Bar按鈕

IBOutlet UIButton *landscapeBarButton;

IBOutlet UIButton *portraitBarButton;

還需要File's Owner和兩個View想關聯。按住Ctrl將File's Owner拖到Portrait上面，在彈出灰色菜單上選擇Portrait同理選擇Landscape。然后在按住Ctrl將File's Owner拖到Landscape上面，在彈出的灰色菜單上選擇View，讓Landscape為自啟動View。

然后是方法的實現：

-(void)willAnimateFirstHalfOfRotationToInterfaceOrientation:(UIInterfaceOrientation)to ration:(NSTimeInterval)ration

{

if(to == UIInterfaceOrientationPortrait)

{

self.view = self.portrait;

self.view.transform = CGAffineTransformIdentity;

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

self.view.bounds = CGRectMake(0.0, 0.0, 320.0, 460.0);

}

else if (to == UIInterfaceOrientationLandscapeLeft)

{

self.view = self.landscape;

self.view.transform = CGAffineTransformIdentity;

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

self.view.bounds = CGRectMake(0.0, 0.0, 460.0, 320.0);

}

else if (to == UIInterfaceOrientationPortraitUpsideDown)

{

self.view = self.portrait;

self.view.transform = CGAffineTransformIdentity;

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

self.view.bounds = CGRectMake(0.0, 0.0, 320.0, 460.0);

}

else if (to == UIInterfaceOrientationLandscapeRight)

{

self.view = self.landscape;

self.view.transform = CGAffineTransformIdentity;

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

self.view.bounds = CGRectMake(0.0, 0.0, 460.0, 320.0);

}

}

- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation

{

return YES;

}

不要忘了在dealloc中釋放資源哦。

因為在上面的代碼中使用到了Core Graphics框架，因此要把該框架連接到該項目中，具體的方法是：在Resources上面點右鍵Add->Existing Frameworks。然后就是查找路徑了。我第一次就看錯了沒有找到，哎，做事情不下心呀！具體路徑為：/Developer/Platforms /iPhoneSimulator.platform/Developer/SDKs/iPhoneSimulator2.2.1.sdk/System /Library/Frameworks/CoreGraphics.framework 呵呵，這個路徑是有點長不好找，記住不是在：/Developer/SDKs里面了，我剛開始就是找到呢里面了。呵呵！還有就是導入后會處理一個提示框， 不要Copy，Reference Type要選擇Relative to Current SDK然后add就OK了。

例子中還有一個方法是對View中的按鈕實現隱藏的，這個就比較簡單了！

具體方法為：

-(IBAction)buttonPressed:(id)sender

{

if(sender == portraitFooButton||sender == landscapeFooButton)

{

portraitFooButton.hidden=YES;

landscapeFooButton.hidden=YES;

}

else

{

portraitBarButton.hidden=YES;

landscapeBarButton.hidden=YES;

}

}

呵呵，上圖兩張看看：

剛開始運行時的圖片

旋轉后并且按了Foo按鈕后的圖片

很赞哦!（95581）
