利用 MBProgress 提供的接口方法進(jìn)行了二次封裝拓展.為了更好的使用,特此記錄一下,方便今后開(kāi)發(fā)使用帶來(lái)便捷.
如有更好更優(yōu)的 demo 歡迎大家分享,共同進(jìn)步!

若不想單起一個(gè)類(lèi)也可以在當(dāng)前調(diào)用方法之處手動(dòng)添加 runloop 來(lái)實(shí)現(xiàn),具體 code 實(shí)現(xiàn)如下:
dispatch_after(dispatch_time(DISPATCH_TIME_NOW, 0.001 * NSEC_PER_SEC), dispatch_get_main_queue(), ^{
????????// insert your task code here
????????[MBProgressHUD showError:@"請(qǐng)輸入您的賬號(hào)" toView:self.view];
});
不斷更新中.
