MBProgressHUD 第三方库使用

关键操作：

 

效果如下：

 

ViewController.h

 #import <UIKit/UIKit.h>
 #import "MBProgressHUD.h"

 @interface ViewController : UITableViewController<MBProgressHUDDelegate>
 @property (strong, nonatomic) MBProgressHUD *hud;
 @property (copy, nonatomic) NSArray *arrMode;
 @property (copy, nonatomic) NSArray *arrModeName;

 @end
