MBProgressHUD 第三方库使用

关键操作：

效果如下：

ViewController.h

1 #import <UIKit/UIKit.h>
2 #import "MBProgressHUD.h"
3 
4 @interface ViewController : UITableViewController<MBProgressHUDDelegate>
5 @property (strong, nonatomic) MBProgressHUD *hud;
6 @property (copy, nonatomic) NSArray *arrMode;
7 @property (copy, nonatomic) NSArray *arrModeName;
8 
9 @end

ViewController.m

  1 #import "ViewController.h"
