出於用戶體驗大多數應用在應用首次啟動時，顯示一個簡單的介紹頁面也就是用戶引導頁面,如下效果：

自己也試著嘗試了一下，主要是使用scrollview實現視圖的切換，當切換到最後一張時會出現一個開始按鈕，點擊開始按鈕關閉引導。 開始按鈕點擊處理： [cpp] - (IBAction)startButtonDidPressed:(id)sender{     [self.startButton setHidden:YES];     NSArray *array = [UIImage splitImageIntoTwoParts:self.imageView.image];     self.left = [[UIImageView alloc] initWithImage:[array objectAtIndex:0]];     float height = DEVICE_IS_IPHONE5 ? 568 : 480;     [self.left setFrame:CGRectMake(0, 0, 320, height)];     self.right = [[UIImageView alloc] initWithImage:[array objectAtIndex:1]];     [self.right setFrame:CGRectMake(0, 0, 320, height)];     [self addSubview:self.left];     [self addSubview:self.right];     [self.pageScroll setHidden:YES];     [self.pageControl setHidden:YES];     self.left.transform = CGAffineTransformIdentity;     self.right.transform = CGAffineTransformIdentity;     [UIView beginAnimations:@"split" context:nil];     [UIView setAnimationDelegate:self];     [UIView setAnimationDuration:1.2];     [UIView setAnimationDidStopSelector:@selector(animationDidStop:finished:context:)];     [self.left setAlpha:0.15];     [self.right setAlpha:0.15];     self.left.transform = CGAffineTransformMakeTranslation(-180 ,0);     self.right.transform = CGAffineTransformMakeTranslation(180 ,0);     [UIView commitAnimations]; } - (IBAction)startButtonDidPressed:(id)sender{     [self.startButton setHidden:YES];     NSArray *array = [UIImage splitImageIntoTwoParts:self.imageView.image];     self.left = [[UIImageView alloc] initWithImage:[array objectAtIndex:0]];     float height = DEVICE_IS_IPHONE5 ? 568 : 480;     [self.left setFrame:CGRectMake(0, 0, 320, height)];     self.right = [[UIImageView alloc] initWithImage:[array objectAtIndex:1]];     [self.right setFrame:CGRectMake(0, 0, 320, height)];     [self addSubview:self.left];     [self addSubview:self.right];     [self.pageScroll setHidden:YES];     [self.pageControl setHidden:YES];     self.left.transform = CGAffineTransformIdentity;     self.right.transform = CGAffineTransformIdentity;     [UIView beginAnimations:@"split" context:nil];     [UIView setAnimationDelegate:self];     [UIView setAnimationDuration:1.2];     [UIView setAnimationDidStopSelector:@selector(animationDidStop:finished:context:)];     [self.left setAlpha:0.15];     [self.right setAlpha:0.15];     self.left.transform = CGAffineTransformMakeTranslation(-180 ,0);     self.right.transform = CGAffineTransformMakeTranslation(180 ,0);     [UIView commitAnimations]; } 將最後一張圖片切割成兩部分，添加一個“開門的動畫”，動畫結束時移除圖片： [cpp] -(void)animationDidStop:(NSString *)animationID finished:(NSNumber *)finished context:(void *)context {     [[UIApplication sharedApplication] setStatusBarHidden:NO withAnimation:UIStatusBarAnimationNone];     if ([animationID isEqualToString:@"split"] && finished) {         [self.left removeFromSuperview];         [self.right removeFromSuperview];     }     [self removeFromSuperview]; } -(void)animationDidStop:(NSString *)animationID finished:(NSNumber *)finished context:(void *)context {     [[UIApplication sharedApplication] setStatusBarHidden:NO withAnimation:UIStatusBarAnimationNone];     if ([animationID isEqualToString:@"split"] && finished) {         [self.left removeFromSuperview];         [self.right removeFromSuperview];     }     [self removeFromSuperview]; } 說明：splitImageIntoTwoParts （Terry Lin 實現）是實現了UIImage的分類，將圖片分割成兩部分。
