本文详细介绍了MBProgressHUD在iOS开发中的使用方法，包括直接在视图上显示、使用block执行任务时显示、显示圆形进度条以及自定义view等场景，并提供了完整的代码示例。

和gitHub上的Demo其实差不多，就是小整理了下，当备忘，想做复杂的效果可以参考MBProgressHUD在gitHub上的DEMO，写得也很清楚明了。

先下载MBProgressHUD.h和.m文件，拖入工程。地址：MBProgressHUD

以下是代码：（先在.h文件里定义 MBProgressHUD *HUD;）

  1 //方式1.直接在View上show  
  2 
  3 HUD = [[MBProgressHUD showHUDAddedTo:self.view animated:YES] retain];  
  4 
  5 
  6 HUD.delegate = self;  
  7 
  8 //常用的设置  
  9 
 10 //小矩形的背景色  
 11 
 12 HUD.color = [UIColor clearColor];//这儿表示无背景  
 13 
 14 //显示的文字  
 15 
 16 HUD.labelText = @"Test";  
 17 
 18 //细节文字  
 19 
 20 HUD.detailsLabelText = @"Test detail";  
 21 
 22 //是否有庶罩  
 23 
 24 HUD.dimBackground = YES;  
 25 
 26 [HUD hide:YES afterDelay:2];  
 27 
 28 //只显示文字  
 29 
 30 MBProgressHUD *hud = [MBProgressHUD showHUDAddedTo:self.view animated:YES];  
 31 
 32 hud.mode = MBProgressHUDModeText;  
 33 
 34 hud.labelText = @"Some message...";  
 35 
 36 hud.margin = 10.f;  
 37 
 38 hud.yOffset = 150.f;  
 39 
 40 hud.removeFromSuperViewOnHide = YES;  
 41 
 42 [hud hide:YES afterDelay:3];  
 43 


 44 //方式2.initWithView  
 45 
 46 //use block  
 47 
 48 HUD = [[MBProgressHUD alloc] initWithView:self.view];  
 49 
 50 [self.view addSubview:HUD];  
 51 
 52 HUD.labelText = @"Test";  
 53 
 54 [HUD showAnimated:YES whileExecutingBlock:^{  
 55 
 56     NSLog(@"%@",@"do somethings....");  
 57 
 58     [self doTask];  
 59 
 60 } completionBlock:^{  
 61 
 62     [HUD removeFromSuperview];  
 63 
 64     [HUD release];          
 65 
 66 }];  
 67 
 68 //圆形进度条  
 69 
 70 HUD = [[MBProgressHUD alloc] initWithView:self.view];  
 71 
 72 [self.view addSubview:HUD];  
 73 
 74 HUD.mode = MBProgressHUDModeAnnularDeterminate;  
 75 
 76 HUD.delegate = self;  
 77 
 78 HUD.labelText = @"Loading";  
 79 
 80 [HUD showWhileExecuting:@selector(myProgressTask) onTarget:self withObject:nil animated:YES];  
 81 
 82 //自定义view  
 83 
 84 HUD = [[MBProgressHUD alloc] initWithView:self.view];  
 85 
 86 HUD.customView = [[[UIImageView alloc] initWithImage:[UIImage imageNamed:@"37x-Checkmark.png"]] autorelease];  
 87 
 88 // Set custom view mode  
 89 
 90 HUD.mode = MBProgressHUDModeCustomView;  
 91 
 92 HUD.delegate = self;  
 93 
 94 HUD.labelText = @"Completed";  
 95 
 96 [HUD show:YES];  
 97 
 98 [HUD hide:YES afterDelay:3];  
 99 
100 //代理方法：
101 
102 #pragma mark -  
103 
104 #pragma mark HUD的代理方法,关闭HUD时执行  
105 
106 -(void)hudWasHidden:(MBProgressHUD *)hud  
107 
108 {  
109 
110     [hud removeFromSuperview];  
111 
112     [hud release];  
113 
114     hud = nil;  
115 
116 }  
117 
118 二个task
119 
120  
121 
122 
123 
124 
125   -(void) doTask{  
126 
127 //你要进行的一些逻辑操作  
128 
129     sleep(2);  
130 
131   }  
132 
133   -(void) myProgressTask{  
134 
135 float progress = 0.0f;  
136 
137 while (progress < 1.0f) {  
138 
139     progress += 0.01f;  
140 
141     HUD.progress = progress;  
142 
143     usleep(50000);
