作为一个开发者，有一个学习的氛围跟一个交流圈子特别重要，这是一个我的iOS交流群：812157648，不管你是小白还是大牛欢迎入驻，分享BAT,阿里面试题、面试经验，讨论技术，大家一起交流学习成长！

一、画线

画线效果

-(void)drawRect:(CGRect)rect{
    UIBezierPath *path = [UIBezierPath bezierPath];
    [path moveToPoint:CGPointMake(0, 0)]; //设置起点
    [path addLineToPoint:CGPointMake(50, 100)];
    [path addLineToPoint:CGPointMake(150, 50)];
    [path addLineToPoint:CGPointMake(300, 300)];
    
    path.lineCapStyle = kCGLineCapRound;//终点类型
    path.lineJoinStyle = kCGLineJoinRound;//交叉点类型
    path.lineWidth = 10.0;
    
//    UIColor *fillColor = [UIColor orangeColor];
//    [fillColor set];
//    [path fill]; //颜色填充
    
    UIColor *redColor = [UIColor redColor];
    [redColor set];
   [path stroke];//划线
}

二、矩形

画矩形

-(void)drawRect:(CGRect)rect{
    
    UIBezierPath *path = [UIBezierPath bezierPathWithRect:CGRectMake(50, 50, 200, 200)];
    path.lineWidth =5;
    UIColor *strokeColor = [UIColor orangeColor];
    [strokeColor set];
    [path stroke];
 
}

三、椭圆、圆

椭圆、圆

#pragma mark -绘制圆圈、椭圆
-(void)drawRect:(CGRect)rect{
    UIBezierPath *path = [UIBezierPath bezierPathWithOvalInRect:CGRectMake(100, 50, 200, 100)];
        
        path.lineWidth =3.0;

        UIColor *strokeColor = [UIColor orangeColor];
        [strokeColor set];
        
        [path stroke];
}

四、圆角矩形

圆角矩形

#pragma mark -圆角矩形
-(void)drawRect:(CGRect)rect{

    UIBezierPath *path = [UIBezierPath bezierPathWithRoundedRect:CGRectMake(100, 50, 150, 150) cornerRadius:6];

      path.lineWidth =2;
      
      UIColor *fillcolor = [UIColor orangeColor];
      [fillcolor set];
      
      [path stroke];
}

五、矩形的某个角为圆角

矩形的某个角为圆角

#pragma mark -矩形的某个角为圆角
-(void)drawRect:(CGRect)rect{
    UIBezierPath *path = [UIBezierPath bezierPathWithRoundedRect:CGRectMake(100, 80, 150, 150) byRoundingCorners:UIRectCornerBottomRight cornerRadii:CGSizeMake(20, 20)];
    
    path.lineWidth =2;
    
    UIColor *color = [UIColor orangeColor];
    [color set];
    
    [path stroke];
}
