代碼實(shí)現(xiàn)引導(dǎo)頁遮罩（2）

新建HJHoledView類犹芹，代碼如下：

繪制遮罩可以畫(圓形,矩形,圓角矩形,自定義視圖)

添加箭頭和提示文字

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];

//按鈕-圓角矩形

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

[self.holedView addFocusView:_myButton];

//圓形

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

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

//文字說明

//[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)];

//添加箭頭

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

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