iOS assumes that writing a hint-driven view of the picture can guide user behavior

First:

This uiview can write:

-(ID) initWithFrame: (CGRect) frame backimage: (uiimage*) Image msgStr: (nsstring*) txt txtcolor: (uicolor*) color{sel    f = [Super Initwithframe:frame];        if (self) {self.backgroundcolor = [uicolor Clearcolor];        _paopaoimage = image;        _txt = txt;            _color = color; } return self;} Only override Drawrect:if-perform custom drawing.//an empty implementation adversely affects performance during a    nimation.-(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];} 

And then pops up:

-(void) showtipview{    cgrect rect = [[Homepageuimanager sharedinstance] categorytipviewframewhenlaunch];    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;//animation repeat times    jumpanimation.autoreverses = yes;//whether to take the initiative repeatedly    [Menu.layer addanimation:jumpanimation forkey:@ "Animatelayer"];}
