下面是内存溢出 jb51.cc 通过网络收集整理的代码片段。

内存溢出小编现在分享给大家，也给大家做个参考。

//画四个边角    CGContextSetlinewidth(ctx,2);    CGContextSetRGBstrokecolor(ctx,83 /255.0,239/255.0,111/255.0,1);//绿色        //左上角    CGPoint poinstopleftA[] = {        CGPointMake(rect.origin.x+0.7,rect.origin.y),CGPointMake(rect.origin.x+0.7,rect.origin.y + 15)    };        CGPoint poinstopleftB[] = {CGPointMake(rect.origin.x,rect.origin.y +0.7),CGPointMake(rect.origin.x + 15,rect.origin.y+0.7)};    [self addline:poinstopleftA pointB:poinstopleftB ctx:ctx];        //左下角    CGPoint poinsBottomleftA[] = {CGPointMake(rect.origin.x+ 0.7,rect.origin.y + rect.size.height - 15),CGPointMake(rect.origin.x +0.7,rect.origin.y + rect.size.height)};    CGPoint poinsBottomleftB[] = {CGPointMake(rect.origin.x,rect.origin.y + rect.size.height - 0.7),CGPointMake(rect.origin.x+0.7 +15,rect.origin.y + rect.size.height - 0.7)};    [self addline:poinsBottomleftA pointB:poinsBottomleftB ctx:ctx];        //右上角    CGPoint poinstopRightA[] = {CGPointMake(rect.origin.x+ rect.size.wIDth - 15,rect.origin.y+0.7),CGPointMake(rect.origin.x + rect.size.wIDth,rect.origin.y +0.7 )};    CGPoint poinstopRightB[] = {CGPointMake(rect.origin.x+ rect.size.wIDth-0.7,CGPointMake(rect.origin.x + rect.size.wIDth-0.7,rect.origin.y + 15 +0.7 )};    [self addline:poinstopRightA pointB:poinstopRightB ctx:ctx];        CGPoint poinsBottomrightA[] = {CGPointMake(rect.origin.x+ rect.size.wIDth -0.7,rect.origin.y+rect.size.height+ -15),CGPointMake(rect.origin.x-0.7 + rect.size.wIDth,rect.origin.y +rect.size.height )};    CGPoint poinsBottomrightB[] = {CGPointMake(rect.origin.x+ rect.size.wIDth - 15,rect.origin.y + rect.size.height-0.7),rect.origin.y + rect.size.height - 0.7 )};    [self addline:poinsBottomrightA pointB:poinsBottomrightB ctx:ctx];    CGContextstrokePath(ctx);
