【代碼筆記】iOS-MBProgressHUDDemo，mbprogresshuddemo

一，工程圖。

二，代碼。

RootViewController.h

#import <UIKit/UIKit.h>//加入標頭檔#import "MBProgressHUD.h"@interface RootViewController : UIViewController<MBProgressHUDDelegate> {    MBProgressHUD *HUD;}@end

 

RootViewController.m

#import "RootViewController.h"//加入標頭檔#import <unistd.h>@interface RootViewController ()@end@implementation RootViewController- (id)initWithNibName:(NSString *)nibNameOrNil bundle:(NSBundle *)nibBundleOrNil{    self = [super initWithNibName:nibNameOrNil bundle:nibBundleOrNil];    if (self) {        // Custom initialization    }    return self;}- (void)viewDidLoad{    [super viewDidLoad];    // Do any additional setup after loading the view.    //轉動3s後停止    HUD = [[MBProgressHUD alloc] initWithView:self.navigationController.view];    HUD.delegate = self;    [HUD showWhileExecuting:@selector(myTask) onTarget:self withObject:nil animated:YES];    [self.navigationController.view addSubview:HUD];}//等待3s- (void)myTask {    sleep(3);}
