Use uibezierpath to implement a view with rounded corners

-(Void) drawrect :( cgrect) rect {// draw a box with rounded corners to fill the view-uibezierpath * roundedrect = [uibezierpath bezierpathwithroundedrect: Self. bounds cornerradius: 5.0f]; [[uicolor colorwithwhite: 0.8 ALPHA: 0.5] setfill]; [roundedrect fillwithblendmode: kcgblendmodenormal ALPHA: 1];}

The uibezierpath object is an encapsulation of the cgpathref data type. If the path is vector-based, it is created using straight lines and curve segments. We use line segments to create Rectangles and polygon, and use curve segments to create arcs, circles, or other complex curve shapes.

 

Uibezierpath

Uibezierpath is described in detail. I will not talk about it here!
