DMProgressHUD是一款用于显示异步操作任务进度状态的视图工具。 该工具包含了目前较为主流的加载状态视图类型,后续会根据具体情况或需求进行迭代。 DMProgressHUD从设计层次的角度来看,其包含了5种展示模式:
- Loading(加载中相关);
- Progress(进度具体值相关);
- Status(状态相关,例如成功、失败等提示);
- Text(文字提示相关);
- Custom(自定义视图相关)。
- 在Podfile文件加入
pod 'DMProgressHUD'
; - 在终端输入
pod install
; - 在需要使用的地方导入头文件
#import <DMProgressHUD.h>
。
- 把DMProgressHUD.h、DMProgressHUD.m和DMProgressImgs.bundle(图片资源bundle)导入到工程目录下;
- 在需要使用的地方导入头文件
#import "DMProgressHUD.h"
。
注意:快捷调用使用默认的样式(Style-Dark)、动画(Animation-gradient)、遮盖(Mask-None)。

- 关于调用:DMProgressHUD为调用者提供了快捷调用的方法,另外还提供了一些与额外功能相关的初始化方法供调用者使用;
- 关于外观:DMProgressHUD提供两种外观样式,对应分别是Dark/Light;
- 关于动画:DMProgressHUD默认使用颜色渐变(alpha)动画进行显示/隐藏,另外还有增量式动画和弹性动画供使用者选择;
- 关于遮盖:DMProgressHUD默认不使用遮盖,另外提供透明遮盖和灰色遮盖供使用者选择;
以上所列举关于DMProgressHUD的功能介绍,用户可以通过 运行Demo 查看到相应的效果。除此之外,用户还可以对HUD的 图文间距、颜色等 进行自定义,可以在 DMProgressHUD.h 文件查看更多的API详细介绍。
