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 (strong, nonatomic) NSArray *arrMode; 7 @property (strong, nonatomic) NSArray *arrModeName; 8  9 @end
