A simple approach to the iOS view border

When we draw the UI interface, we usually make the border with a layer and then add a shadow to it, I prefer to use the following method,

UI to get a few frames of picture, with code to stretch the picture

-(UIImage *) Changeborderimage: (UIImage *) borderimage {UIImage*image =Borderimage; CGFloat Top=2;//Top Cover HeightCGFloat bottom =2;//Bottom Cover HeightCGFloat left =2;//Left cover widthCGFloat right =2;//right End cover widthUiedgeinsets insets =Uiedgeinsetsmake (top, left, bottom, right); //specified as stretch mode, re-assigned after scalingImage =[Image Resizableimagewithcapinsets:insets Resizingmode:uiimageresizingmodestretch]; returnimage;}

Customize a border View or add a uiimageview with stretched uiimage underneath your view.

All code:

BorderView.h

Viewcontroller.m

- (void) viewdidload {[Super viewdidload]; Self.view.backgroundColor=[Uicolor Whitecolor]; Borderview*borderview = [[Borderview alloc]initwithframe:cgrectmake ( -, -, -, -) Borderimage:[uiimage imagenamed:@"tool_biankuang2"]];            [Self.view Addsubview:borderview]; Borderview*borderview1 = [[Borderview alloc]initwithframe:cgrectmake ( -, $, Max, -) Borderimage:[uiimage imagenamed:@"tool_biankuang2"]];        [Self.view Addsubview:borderview1]; Borderview*borderview2 = [[Borderview alloc]initwithframe:cgrectmake ( -, -, -, -) Borderimage:[uiimage imagenamed:@"Tool_biankuang"]];    [Self.view Addsubview:borderview2]; }
