XCode Object-C 绘制边框

   Object-C在storyboard中绘制边框：

1、新建Cocoa Class文件Draw类，在Draw.m中重载方法-(void)drawRect:(CGRect)rect:-(void)drawRect:(CGRect)rect {
UIBzierPath *path=[[UIBezierPath alloc] init];
[path moveToPoint:CGPointMake(180,200)];
[path addLineToPoint:CFPointMake(240,350)];
[path addLineToPoint:CGPoingMake(120,350)];

[path closePath];
[[UIColor redColor] setFill];
[[UIColor blueColor] setFill];
[path fill];
[path stroke];
}2、在故事板storyboard总关联Draw类即可。
