iOS development-Automatic carousel diagram creation

Here is the OC version, which is simply recorded below:

The specific code is as follows:

1, prepare

#define FRAME [[UIScreen mainscreen] bounds]#define WIDTH  FRAME.size.width#define HEIGHT FRAME.size.height

2, the concrete realization

 //ScrollView Add-on_bigscrollview = [[Uiscrollview alloc]initwithframe:cgrectmake (0, -, WIDTH, HEIGHT)]; _bigscrollview.showshorizontalscrollindicator=NO; _bigscrollview.contentsize= Cgsizemake (WIDTH *6,0); _bigscrollview.pagingenabled=YES; _bigscrollview.bounces=NO; _bigscrollview.Delegate=Self ;        [Self.view Addsubview:_bigscrollview]; //Add a picture content     for(inti =0; i<6; i++) {Uiimageview*imageview = [[Uiimageview alloc]initwithframe:cgrectmake (i *width,0, WIDTH, HEIGHT)]; Imageview.image= [UIImage imagenamed:[nsstring stringWithFormat:@"%d.jpg", I]];    [_bigscrollview Addsubview:imageview]; }        //creation of Pagecontrol_pagecontrol = [[Uipagecontrol alloc] Initwithframe:cgrectmake (0,0, WIDTH, +)] ; _pagecontrol.center=Cgpointmake (_bigscrollview.center.x, _BIGSCROLLVIEW.CENTER.Y); _pagecontrol.numberofpages=6; _pagecontrol.currentpage=0; _pagecontrol.pageindicatortintcolor=[Uicolor Bluecolor]; _pagecontrol.currentpageindicatortintcolor=[Uicolor Redcolor];    [Self.view Addsubview:_pagecontrol];        [_pagecontrol addtarget:self Action: @selector (Pagecontrollerclick) forcontrolevents:uicontroleventvaluechanged]; //Creation of Timers_timer = [Nstimer scheduledtimerwithtimeinterval:2Target:self selector: @selector (OnTimer) Userinfo:nil Repeats:yes];

3, the implementation of the response method

-(void) pagecontrollerclick{[_bigscrollview setcontentoffset:cgpointmake (_pagecontrol.currentpage* the,0) Animated:yes];}//when the ScrollView starts to slide manually- (void) Scrollviewwillbegindragging: (Uiscrollview *) scrollview{[_timer setfiredate:[nsdate distantfuture];}//add a delay method to ScrollView- (void) Scrollviewdidenddecelerating: (Uiscrollview *) scrollview{_pagecontrol.currentpage= _bigscrollview.contentoffset.x/WIDTH; [Self performselector: @selector (dispast) withobject:nil Afterdelay:2];//Delay Method    }//Start Timer-(void) dispast{[_timer setfiredate:[nsdate distantpast];}Static intCount=1;//the specific response method of the timer-(void) ontimer{_pagecontrol.currentpage+=count; if(_pagecontrol.currentpage==_pagecontrol.numberofpages-1|| _pagecontrol.currentpage==0) {Count=-count;    }; [_bigscrollview setcontentoffset:cgpointmake (_pagecontrol.currentpage*width,0) Animated:yes]; }

No, it's just a record!
