先看效果

基於SV的好處

例如網路載入需要用SV顯示載入資訊，但是載入成功如果是其他toast還需要呼叫SV的dismiss然後才能顯示toast 這裡直接顯示toast即可方便，SV底層是用的單例實現的，這裡隨意彈toast 隨意彈SVProgress都不會有什麼問題。還可以增加toast結束回撥，詳情請看程式碼。

程式碼

這裡封裝四個方法，自由控制顯示時間 YHToastHUD.h

@implementation YHToastHUD

+(void)showToast:(NSString*)msg andDuration:(CGFloat)duration{
    [self showToast:msg andDuration:duration completion:nil];
}

+(void)showToast:(NSString*)msg{
    [self showToast:msg andDuration:1.2];
}

+(void)showToast:(NSString*)msg completion:(nullable ToastHUDDismissCompletion)completion{
    [self showToast:msg andDuration:1.2 completion:^{
        completion();
    }];
}

+(void)showToast:(NSString*)msg andDuration:(CGFloat)duration completion:(nullable ToastHUDDismissCompletion)completion{
    [SVProgressHUD dismiss];
    [SVProgressHUD setDefaultMaskType:SVProgressHUDMaskTypeClear];
    [SVProgressHUD setDefaultStyle:SVProgressHUDStyleDark];
    [SVProgressHUD setImageViewSize:CGSizeMake(0, -1)];
    [SVProgressHUD showImage:[UIImage new] status:msg];
    [SVProgressHUD dismissWithDelay:duration completion:^{
        [SVProgressHUD setDefaultStyle:SVProgressHUDStyleLight];
        [SVProgressHUD setImageViewSize:CGSizeMake(28, 28)];
        [SVProgressHUD setDefaultMaskType:SVProgressHUDMaskTypeBlack];
        if (completion) {
            completion();
        }
    }];
}

@end

 

注意，需要修改一下SV預設配置 在AppDelegate裡面

都修改什麼一看即明白

 [SVProgressHUD setFont:[UIFont systemFontOfSize:RATIO(16)]];
 //這個必須要加保證跳轉頁面前SV要dimiss，
 [SVProgressHUD setDefaultMaskType:SVProgressHUDMaskTypeBlack];
