Fadout飛濺屏幕上的多個圖像在IOS

Question

我想動畫多個圖像的啓動screen.i顯示3圖像作爲啓動屏幕第一個是啓動屏幕的默認圖像比使用Ui-imageview我顯示第二和第三我的Imageview。

我想在更改啓動畫面時淡出圖像。我試過NSTimmer的解決方案，但它顯示我直接第三個圖像和緬因州屏幕比我嘗試後，這個解決方案，但它顯示我我的第二和第三個圖像2次接連不斷。 任何幫助表示讚賞

編輯/ - Nikki建議我一些解決方案，但我有混亂，哪個地方我取消隱藏我的第二個圖像視圖？ 這裏是我的代碼

backgroundImageView = [[UIImageView alloc] initWithFrame:self.view.bounds]; 
backgroundImageView.autoresizingMask = UIViewAutoresizingFlexibleHeight | UIViewAutoresizingFlexibleWidth; 
backgroundImageView.image=[UIImage imageNamed:@"SPLASHSCREEN-2.png"]; 
backgroundImageView2 = [[UIImageView alloc] initWithFrame:self.view.bounds]; 
backgroundImageView2.autoresizingMask = UIViewAutoresizingFlexibleHeight | UIViewAutoresizingFlexibleWidth; 
backgroundImageView2.image=[UIImage imageNamed:@"SPLASHSCREEN-3.png"]; 
[self.view addSubview:backgroundImageView]; 
[self.view addSubview:backgroundImageView2]; 
[backgroundImageView2 setHidden:YES]; 
[self performSelector:@selector(performTransition) withObject:nil afterDelay:1.0]; 

-(void)performTransition 
    { 
CATransition *animation3 = [CATransition animation]; 
[animation3 setDuration:3.0f]; 
[animation3 setType:kCATransitionReveal]; 
[animation3 setTimingFunction:[CAMediaTimingFunction functionWithName:kCAMediaTimingFunctionEaseInEaseOut]]; 
[[backgroundImageView layer] addAnimation:animation3 forKey:@"SwitchToView"]; 
[backgroundImageView setHidden:YES]; 
[backgroundImageView2 setHidden:NO];//No animation happen while changing the image view 
}

U可以創建要顯示在啓動兩種ImageView並將它們隱藏在第一。只需編寫動畫代碼：

-(void)performTransition 
{ 
    CATransition *animation3 = [CATransition animation]; 
    [animation3 setDuration:3.0f]; 
    [animation3 setType:kCATransitionReveal]; 
    [animation3 setTimingFunction:[CAMediaTimingFunction functionWithName:kCAMediaTimingFunctionEaseInEaseOut]]; 
    [[backgroundImageView2 layer] addAnimation:animation3 forKey:@"SwitchToView"]; 
    [backgroundImageView setHidden:YES]; 
    [backgroundImageView2 setHidden:NO];//No animation happen while changing the image view 
} 

並設置ImageView將在取消隱藏時設置動畫。動畫類型可通過更改[animation3 setType:kCATransitionReveal];的值進行更改。 記得導入：#import<QuartzCore/QuartzCore.h>

隱藏以前ImageView動畫和動畫顯示未來ImageView你可以寫一個函數內部的代碼，並可以調用使用performSelector該功能，並可以添加所需的時間間隔。
