UIBezierPath简单实现带箭头view

自定义一个view，在里面划线添加ui

#import "BeazView.h"

@implementation BeazView

-(instancetype)initWithFrame:(CGRect)frame{

self = [super initWithFrame:frame];

if (self) {

[self dosomething];

}

return self;

}

-(void)dosomething{

_bezierPath4 = [UIBezierPath bezierPathWithRoundedRect:CGRectMake(10, 20, self.frame.size.width-20, 100) byRoundingCorners:UIRectCornerAllCorners

cornerRadii:CGSizeMake(10, 10)];

[_bezierPath4 moveToPoint:CGPointMake(100, 0)];

[_bezierPath4 addLineToPoint:CGPointMake(80, 20)];

[_bezierPath4 addLineToPoint:CGPointMake(120, 20)];

_shaperLayer4 = [CAShapeLayer new];

_shaperLayer4.fillColor = [UIColor orangeColor].CGColor;

[self.layer addSublayer:_shaperLayer4];

_shaperLayer4.path = _bezierPath4.CGPath;

_title = [[UILabel alloc]initWithFrame:CGRectMake(10, 20, self.frame.size.width-20, 100)];

_title.text = @"我在上面";

_title.textColor = [UIColor redColor];

[self addSubview:_title];

}

定义一个按钮，实现移除

[UIView animateWithDuration:0.02 animations:^{

[view removeFromSuperview];

} completion:^(BOOL finished) {

}];
