MBGuideHUD主要是为了解决新手引导

快速创建一个MBGuideHUD

//visibleView 为需要镂空的view
 MBGuideHUD *hud = [MBGuideHUD showHUDAddedTo:self.tabBarController.view visibleView:self.middle2 animated:NO];
//现在不能设置毛玻璃效果了
hud.style = MBGuideHUDBackgroundStyleSolidColor;

左边原图，右边效果图.png

自定义效果自定义了一个分类代码见demo

[MBGuideHUD showText:@"只因和我的心和你一起碎" visible:_btn];

下面是MBGuideHUD.h文件

.h文件的设计主要是模仿MBProgressHUD来写的

#import <UIKit/UIKit.h>

typedef NS_ENUM(NSInteger, MBGuideHUDBackgroundStyle) {
    /// 纯色背景
    MBGuideHUDBackgroundStyleSolidColor,
    /// 毛玻璃背景
    MBGuideHUDBackgroundStyleBlur
};
typedef NS_ENUM(NSInteger, MBGuideHUDBlurStyle) {
    /// 白色
    MBGuideHUDBlurStyleLight,
    /// 黑色
    MBGuideHUDBlurStyleDark
};

typedef void (^MBGuideHUDClickBlock)();

@protocol MBGuideHUDDeledate <NSObject>

@optional
- (void)guideHUDTouchesBegan:(NSSet<UITouch *> *)touches withEvent:(UIEvent *)event;
