代码实现引导页遮罩（2）

作者: jing091111 | 来源:发表于2017-04-12 09:46 被阅读13次

新建HJHoledView类，代码如下：

/*

绘制遮罩可以画(圆形,矩形,圆角矩形,自定义视图)

添加箭头和提示文字

案例：

//添加遮罩指示

self.holedView = [[HJHoledView alloc]initWithFrame:self.view.frame];

[self.holedView setDimingColor: [[UIColor redColor] colorWithAlphaComponent:0.75f]];

//self.holedView.holeViewDelegate = self;

[self.view addSubview:_holedView];

//按钮-圆角矩形

[self.holedView addHoleRoundedRectOnRect:_myButton.frame withCornerRadius:_myButton.frame.size.width/2];

[self.holedView addFocusView:_myButton];

//圆形

[self.holedView addHoleCircleCenteredOnPosition:CGPointMake(190, 110) andDiameter:130];

[self.holedView addHoleCircleCenteredOnPosition:CGPointMake(190, 310) andDiameter:130];

//文字说明

//[self.holedView addHCustomView:[self viewForDemo] onRect:CGRectMake(20.0f, 250.0f, 200.0f, 50.0f)];

[self.holedView addPromptLabelText:@"哈哈哈哈哈哈哈哈" onRect:CGRectMake(20.0f, 150.0f, 200.0f, 50.0f)];

[self.holedView addPromptLabelText:@"嘻嘻嘻嘻嘻嘻嘻" onRect:CGRectMake(20.0f, 200.0f, 200.0f, 50.0f)];

//添加箭头

[self.holedView addArrowView:CGPointMake(100, 150) endPoint:CGPointMake(150, 100)];

[self.holedView addArrowView:CGPointMake(100, 250) endPoint:CGPointMake(150, 300)];
