Iphone development-Implementation of the User Guide interface similar to WeChat

For user experience, most applications display a simple introduction page, that is, the user guide page, when the application is started for the first time. The following results are displayed: I tried it myself, scrollview is used to switch views. When you switch to the last view, a start button is displayed. Click the start button to close the guide. Start button click processing: [cpp]-(IBAction) startButtonDidPressed :( id) sender {[self. startButton setHidden: YES]; NSArray * array = [UIImage splitimage1_twoparts: 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 = CGAffineTran SformIdentity; [UIView beginAnimations: @ "split" context: nil]; [UIView Duration: self]; [UIView setAnimationDuration: 1.2]; [UIView Duration: @ 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 splitimage1_twoparts: 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 = CGAffineTran SformIdentity; [UIView beginAnimations: @ "split" context: nil]; [UIView Duration: self]; [UIView setAnimationDuration: 1.2]; [UIView Duration: @ 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];} cut the last image into two parts, add an "open door Animation", and remove the image at the end of the animation: [cpp]-(void) usage :( NSString *) animationID finished :( NSNumber *) finished context :( void *) context {[[UIApplication sharedApplication] setStatusBarHidden: NO withAnimation: role]; if ([animationID isinclutostring: @ "split"] & finished) {[self. left removeFromSuperview]; [self. right removeFromSuperview];} [Self removeFromSuperview];}-(void) Updated :( 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];} Description: splitIma Gew.twoparts (Terry Lin implementation) implements the classification of the UIImage and splits the image into two parts.
