先上图:

这个UIView能够这样写:

-(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];
}

-(void)showTipView{
    CGRect rect = [[HomePageUIManager sharedInstance] categoryTipViewFrameWhenLaunch];
    PopUpMenu* menu = [[PopUpMenu alloc] initWithFrame:rect backImage:[UIImage imageNamed:@"change_search_tip.png"] msgStr:@"打开/关闭面板" txtColor:[CCommon RGBColorFromHexString:@"#ffffff" alpha:1.0f]];
    
    [self.view addSubview:menu];
    
    CABasicAnimation *jumpAnimation = [CABasicAnimation animationWithKeyPath:@"transform.translation.y"];
    jumpAnimation.fromValue = http://www.mamicode.com/[NSNumber numberWithFloat:0.0f];"animateLayer"];
}
