If ios writes a View with an animation prompt, it can guide user behavior.

If ios writes a View with an animation prompt, it can guide user behavior.

First:

This UIView can be written as follows:

-(id)initWithFrame:(CGRect)frame backImage:(UIImage*)image msgStr:(NSString*)txt          txtColor:(UIColor*)color{    self = [super initWithFrame:frame];    if (self) {        self.backgroundColor = [UIColor clearColor];        _paopaoImage = image;        _txt = txt;        _color = color;            }    return self;}// Only override drawRect: if you perform custom drawing.// An empty implementation adversely affects performance during animation.- (void)drawRect:(CGRect)rect{    CGContextRef context = UIGraphicsGetCurrentContext();    CGRect textRc = rect;    [_paopaoImage drawInRect:rect];    CGFontRef contextFont = CGFontCreateWithFontName((CFStringRef)[UIFont systemFontOfSize:14].fontName);    CFRelease(contextFont);        CGContextSetFontSize(context, 14.0);    CGContextSetFillColorWithColor(context, _color.CGColor);    textRc.origin.y += 11.0f;    [_txt drawInRect:textRc withFont:[UIFont systemFontOfSize:14] lineBreakMode:NSLineBreakByWordWrapping alignment:NSTextAlignmentCenter];}

Then, in the pop-up window:

-(Void) showTipView {CGRect rect = [[HomePageUIManager sharedInstance] region]; PopUpMenu * menu = [[PopUpMenu alloc] initWithFrame: rect backImage: [UIImage imageNamed: @ "change_search_tip.png"] msgStr: @ "open/close panel" txtColor: [CCommon RGBColorFromHexString: @ "# ffffff" alpha: 1.0f]; [self. view addSubview: menu]; CABasicAnimation * jumpAnimation = [CABasicAnimation animationWithKeyPath: @ "transform. translation. y "]; jumpAnimation. fromValue = [NSNumber numberWithFloat: 0.0f]; jumpAnimation. toValue = [NSNumber numberWithFloat: 8.0f]; jumpAnimation. duration = 0.5f; // animation duration jumpAnimation. repeatCount = 10; // Number of animation repetitions jumpAnimation. autoreverses = YES; // whether to automatically repeat [menu. layer addAnimation: jumpAnimation forKey: @ "animateLayer"];}
