MBProgressHUD简单封装

项目中需要导入MBProgressHUD和SDWebImage,实现效果如下:

MBProgressHUD简单封装

.h

#import <Foundation/Foundation.h>
#import <UIKit/UIKit.h>
@class MBProgressHUD;

NS_ASSUME_NONNULL_BEGIN

typedef NS_ENUM(NSInteger,GLProgressModel) {

GLProgressModelOnlyText,           //文字
GLProgressModelLoading,            //加载菊花
GLProgressModelCustomImage,   //自定义图片
GLProgressModelCustomGif        //自定义gif图片
};

@interface GLProgressHUD : NSObject

@property (nonatomic,strong) MBProgressHUD  * __nullable hud;

+(instancetype)shareInstance;

//显示菊花和文字
+ (void)showMessage:(NSString *)msg inView:(UIView *)view;

//显示图片、文字
+ (void)showMessage:(NSString *)msg imageName:(NSString *)imageName  inView:(UIView *)view;

//只显示文字
+(void)showOnlyText:(NSString *)msg inView:(UIView *)view afterDelay:(NSTimeInterval)delay;

//显示gif图片
+ (void)showMessage:(NSString *)msg gifName:(NSString *)gifName  inView:(UIView *)view;

//移除hud
+ (void)hide;

@end
