CATransition類實現層的轉場動畫。你可以從一組預定義的轉換或者通過提供定製的CIFilter執行個體來指定轉場效果。
[plain] view plaincopy
- //定義個轉場動畫
- CATransition *animation = [CATransition animation];
- //轉場動畫期間
- animation.duration = 0.2f;
- //計時函數,從頭到尾的流暢度???
- animation.timingFunction=UIViewAnimationCurveEaseInOut;
- //轉場動畫類型
- animation.type = kCATransitionReveal;
- //轉場動畫將去的方向
- animation.subtype = kCATransitionFromBottom;
- //動畫時你需要的實現
- self.tabBarController.tabBar.hidden = YES;
- //添加動畫 (轉場動畫是添加在層上的動畫)
- self.tabBarController.tabBar.layer addAnimation:animation forKey:@"animation"];
說明:
duration:動畫持續的時間長度。
timingFunction:沒明白(誰明白的說明一下吧)
type:轉場動畫的類型。如果在一個自訂的轉場動畫中指定的過濾器屬性,此屬性將被忽略。
type共有四種類型:
NSString * const kCATransitionFade;//逐漸消失NSString * const kCATransitionMoveIn;//移入NSString * const kCATransitionPush;//平移(暫且這麼稱呼吧)NSString * const kCATransitionReveal;//顯露
預設類型為kCATransitionFade。
subtype:轉場動畫將要去往的方向。
subtpye有四種類型:
NSString * const kCATransitionFromRight;NSString * const kCATransitionFromLeft;NSString * const kCATransitionFromTop;NSString * const kCATransitionFromBottom;
預設方向是nil。
[self.tabBarController.tabBar.layer addAnimation:animation forKey:@"animation"];
轉場動畫是添加給layer的!
以下幾種轉場動畫調用的蘋果的私人API,注意咯,小心用了之後被蘋果打回來。

- switch (btn.tag) {
- case 0:
- animation.type = @"cube";//---立方體
- break;
- case 1:
- animation.type = @"suckEffect";//103 吸走的效果
- break;
- case 2://前後翻轉效果
- animation.type = @"oglFlip";//When subType is "fromLeft" or "fromRight", it‘s the official one.
- break;
- case 3:
- animation.type = @"rippleEffect";//110波紋效果
- break;
- case 4:
- animation.type = @"pageCurl";//101翻頁起來
- break;
- case 5:
- animation.type = @"pageUnCurl";//102翻頁下來
- break;
- case 6:
- animation.type = @"cameraIrisHollowOpen ";//107//鏡頭開
- break;
- case 7:
- animation.type = @"cameraIrisHollowClose ";//106鏡頭關
- break;
- default:
