1. Set the frame

2. Setting up a picture

Add Pagecontrol

Pagecontrol.bounds = CGRectMake (0, 0, 150, 50);

Pagecontrol.numberofpages = Kcount; show how many dots (how many pages)

Set the dot color of a non-selected page

Pagecontrol.pageindicatortintcolor = [Uicolor Redcolor];

Set the dot color of the selected page

Pagecontrol.currentpageindicatortintcolor = [Uicolor Bluecolor];

Disable the default click function

pagecontrol.enabled = NO;

[Self.view Addsubview:pagecontrol];

_pagecontrol = Pagecontrol;

}
