MBProgressHUD是一个开源类库，实现了各种样式的提示框，下载地址：https://github.com/jdg/MBProgressHUD，然后把两个MBProgressHUD.h和MBProgressHUD.m放到自己的项目就可以了。这里有一个小Demo可以参考一下。

头文件部分：

#import <UIKit/UIKit.h>

#import "MBProgressHUD.h"

@interface ViewController : UIViewController

{

    MBProgressHUD *HUD;

}

- (IBAction)showTextDialog:(id)sender;      //文本提示框，默认情况下

- (IBAction)showProgressOne:(id)sender;     //第一种加载提示框

- (IBAction)showProgressTwo:(id)sender;     //第二种加载提示框

- (IBAction)showProgressThree:(id)sender;   //第三种加载提示框

- (IBAction)showCustomDialog:(id)sender;    //自定义提示框，显示打钩效果

- (IBAction)showAllTextDialog:(id)sender;   //显示纯文本提示框

@end

实现文件部分

#import "ViewController.h"

@interface ViewController ()

@end

@implementation ViewController

- (void)viewDidLoad

{

    [super viewDidLoad];

    // Do any additional setup after loading the view, typically from a nib.

}

- (void)didReceiveMemoryWarning

{

    [super didReceiveMemoryWarning];

    // Dispose of any resources that can be recreated.

}

- (IBAction)showTextDialog:(id)sender {

    HUD = [[MBProgressHUD alloc] initWithView:self.view];

    [self.view addSubview:HUD];

    HUD.dimBackground = YES;  //把当前的view置于后台

    HUD.labelText = @"请稍等";

    //显示对话框

    [HUD showAnimated:YES whileExecutingBlock:^{

        sleep();

    } completionBlock:^{

    }];

}

- (IBAction)showProgressOne:(id)sender {

    HUD = [[MBProgressHUD alloc] initWithView:self.view];

    [self.view addSubview:HUD];

    HUD.labelText = @"正在加载";

    HUD.mode = MBProgressHUDModeDeterminate;

    //HUD.mode = MBProgressHUDModeAnnularDeterminate;

    [HUD showAnimated:YES whileExecutingBlock:^{

        float progress = 0.0f;

        while (progress < 1.0f) {

            progress += 0.01f;

            HUD.progress = progress;

            usleep();

        }

    } completionBlock:^{

        [HUD removeFromSuperview];

        [HUD release];

        HUD = nil;

    }];

}

- (IBAction)showProgressTwo:(id)sender {

    HUD = [[MBProgressHUD alloc] initWithView:self.view];

    [self.view addSubview:HUD];

    HUD.labelText = @"正在加载";

    HUD.mode = HUD.mode = MBProgressHUDModeAnnularDeterminate;

    [HUD showAnimated:YES whileExecutingBlock:^{

        float progress = 0.0f;

        while (progress < 1.0f) {

            progress += 0.01f;

            HUD.progress = progress;

            usleep();

        }

    } completionBlock:^{

        [HUD removeFromSuperview];

        [HUD release];

        HUD = nil;

    }];
