MBProgressHUD是一个开源项目，实现了很多种样式的提示框，使用上简单、方便，并且可以对显示的内容进行自定义，功能很强大，很多项目中都有使用到。到GitHub上可以下载到项目源码https://github.com/jdg/MBProgressHUD，下载下来后直接把MBProgressHUD.h和MBProgressHUD.m拖入工程中就行，别忘了选择拷贝到工程。完了在需要使用的地方导入头文件就可以开始使用了。首先看下工程截图： 

 

接下来是整个Demo的完整界面，这里我只选择出了几个常用的对话框，其他样式的在源码提供的Demo里可以找到，要用的话直接参考就可以。 

 

接下来直接上代码了，头文件部分：

#import 
    
       #import "MBProgressHUD.h"  @interface ViewController : UIViewController  {      //HUD（Head-Up Display，意思是抬头显示的意思）      MBProgressHUD *HUD;  }  - (IBAction)showTextDialog:(id)sender;  - (IBAction)showProgressDialog:(id)sender;  - (IBAction)showProgressDialog2:(id)sender;  - (IBAction)showCustomDialog:(id)sender;  - (IBAction)showAllTextDialog:(id)sender;  @end
    

实现文件（按钮实现部分）：

- (IBAction)showTextDialog:(id)sender {      //初始化进度框，置于当前的View当中      HUD = [[MBProgressHUD alloc] initWithView:self.view];      [self.view addSubview:HUD];      //如果设置此属性则当前的view置于后台      HUD.dimBackground = YES;      //设置对话框文字      HUD.labelText = @"请稍等";      //显示对话框      [HUD showAnimated:YES whileExecutingBlock:^{          //对话框显示时需要执行的操作          sleep(3);      } completionBlock:^{          //操作执行完后取消对话框          [HUD removeFromSuperview];          [HUD release];          HUD = nil;      }];  }  - (IBAction)showProgressDialog:(id)sender {      HUD = [[MBProgressHUD alloc] initWithView:self.view];      [self.view addSubview:HUD];      HUD.labelText = @"正在加载";      //设置模式为进度框形的      HUD.mode = MBProgressHUDModeDeterminate;      [HUD showAnimated:YES whileExecutingBlock:^{          float progress = 0.0f;          while (progress < 1.0f) {              progress += 0.01f;              HUD.progress = progress;              usleep(50000);          }      } completionBlock:^{          [HUD removeFromSuperview];          [HUD release];          HUD = nil;      }];  }  - (IBAction)showProgressDialog2:(id)sender {      HUD = [[MBProgressHUD alloc] initWithView:self.view];      [self.view addSubview:HUD];      HUD.labelText = @"正在加载";      HUD.mode = MBProgressHUDModeAnnularDeterminate;      [HUD showAnimated:YES whileExecutingBlock:^{          float progress = 0.0f;          while (progress < 1.0f) {              progress += 0.01f;              HUD.progress = progress;              usleep(50000);          }      } completionBlock:^{          [HUD removeFromSuperview];          [HUD release];          HUD = nil;      }];  }  - (IBAction)showCustomDialog:(id)sender {      HUD = [[MBProgressHUD alloc] initWithView:self.view];      [self.view addSubview:HUD];      HUD.labelText = @"操作成功";      HUD.mode = MBProgressHUDModeCustomView;      HUD.customView = [[[UIImageView alloc] initWithImage:[UIImage imageNamed:@"Checkmark"]] autorelease];      [HUD showAnimated:YES whileExecutingBlock:^{          sleep(2);      } completionBlock:^{          [HUD removeFromSuperview];          [HUD release];          HUD = nil;      }];  }  - (IBAction)showAllTextDialog:(id)sender {      HUD = [[MBProgressHUD alloc] initWithView:self.view];      [self.view addSubview:HUD];      HUD.labelText = @"操作成功";      HUD.mode = MBProgressHUDModeText;      //指定距离中心点的X轴和Y轴的偏移量，如果不指定则在屏幕中间显示  //    HUD.yOffset = 150.0f;  //    HUD.xOffset = 100.0f;      [HUD showAnimated:YES whileExecutingBlock:^{          sleep(2);      } completionBlock:^{          [HUD removeFromSuperview];          [HUD release];          HUD = nil;      }];  }

依次实现的效果如下： 

 

下面这个效果就类似中的Toast： 

 

以上就简单介绍了MBProgressHUD的使用，这里都是采用block的形式来操作的，这样写起代码来更直观也更高效。
