判断引导页首次出现方式：
//选择根控制器 +(void)chooseRootViewController{ //初始化Window窗口 [AppDelegate Delegate].window = [[UIWindow alloc]initWithFrame:[UIScreen mainScreen].bounds]; [AppDelegate Delegate].window.backgroundColor = [UIColor whiteColor]; [[AppDelegate Delegate].window makeKeyAndVisible]; //取出沙盒中存储的上次使用软件的版本号
NSString *key = @"CFBundleVersion";
NSString *lastVersion = [defaluts stringForKey:key]; //获取当前软件的版本号 NSString *currentVersion = [NSBundle mainBundle].infoDictionary[key]; if ([currentVersion isEqualToString:lastVersion]) { if ([ToolManager maitchWithAccountNumAndPassword] && [ToolManager IsOrNoAutoLogin]== YES) { //登录成功,进入主控制器 [AppDelegate Delegate].window.rootViewController = [[KJTabViewController alloc]init]; }else{ //用户已经注册过,进入登陆控制器 [self setLoginVC]; } }else{ //用户初次使用,进入引导页控制器 [AppDelegate Delegate].window.rootViewController = [[KJGuidePageController alloc]init]; //存储新的版本号 [defaluts setObject:currentVersion forKey:key]; [defaluts synchronize]; } }
版本更新方式：http://www.cnblogs.com/jys509/p/5390505.html
1.获取当前项目APP版本号
2.拿到AppStore项目版本号
3.对比版本号,实现更新功能
第一种方式：
/** * 检测app更新 */ -(void)hsUpdateApp { //1.先获取当前工程项目版本号 NSDictionary *infoDic=[[NSBundle mainBundle] infoDictionary]; NSString *currentVersion=infoDic[@"CFBundleShortVersionString"]; //2.从网络获取appStore版本号 NSError *error; NSData *response = [NSURLConnection sendSynchronousRequest:[NSURLRequest requestWithURL:[NSURL URLWithString:[NSString stringWithFormat:@"http://itunes.apple.com/cn/lookup?id=%@",STOREAPPID]]] returningResponse:nil error:nil]; if (response == nil) { NSLog(@"你没有连接网络哦"); return; } NSDictionary *appInfoDic = [NSJSONSerialization JSONObjectWithData:response options:NSJSONReadingMutableLeaves error:&error]; if (error) { NSLog(@"hsUpdateAppError:%@",error); return; } NSArray *array = appInfoDic[@"results"]; NSDictionary *dic = array[0]; NSString *appStoreVersion = dic[@"version"]; //3.打印版本号 NSLog(@"当前版本号:%@\n商店版本号:%@",currentVersion,appStoreVersion); //4当前版本号小于商店版本号,就更新 if([currentVersion floatValue] < [appStoreVersion floatValue]) { UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"版本有更新" message:[NSString stringWithFormat:@"检测到新版本(%@),是否更新?",appStoreVersion] delegate:self cancelButtonTitle:@"取消"otherButtonTitles:@"更新",nil]; [alert show]; }else{ NSLog(@"版本号好像比商店大噢!检测到不需要更新"); } } - (void)alertView:(UIAlertView*)alertView clickedButtonAtIndex:(NSInteger)buttonIndex { //5.实现跳转到应用商店进行更新 if(buttonIndex==1) { //6.此处加入应用在app store的地址，方便用户去更新，一种实现方式如下： NSURL *url = [NSURL URLWithString:[NSString stringWithFormat:@"https://itunes.apple.com/us/app/id%@?ls=1&mt=8", STOREAPPID]]; [[UIApplication sharedApplication] openURL:url]; } }
第二种方式：
#pragma mark - 版本判断 /** * 专用检测app更新 */ -(void)judgeVersionUpdate { NSString *urlStr = [NSString stringWithFormat:@"http://itunes.apple.com/cn/lookup?id=%@",STOREAPPID]; NSURL *url = [NSURL URLWithString:urlStr]; NSURLRequest *req = [NSURLRequest requestWithURL:url]; [NSURLConnection connectionWithRequest:req delegate:self]; } -(void)connection:(NSURLConnection *)connection didReceiveData:(NSData *)data{ NSError *error; id jsonObject = [NSJSONSerialization JSONObjectWithData:data options:NSJSONReadingAllowFragments error:&error]; NSDictionary *appInfo = (NSDictionary *)jsonObject; NSArray *infoContent = [appInfo objectForKey:@"results"]; NSString *appStoreVersion = [[infoContent objectAtIndex:0] objectForKey:@"version"]; KJLog(@"商店的版本是:%@",appStoreVersion); NSDictionary *infoDic = [[NSBundle mainBundle] infoDictionary]; NSString *currentVersion = [infoDic objectForKey:@"CFBundleShortVersionString"]; KJLog(@"当前的版本是:%@",currentVersion); if (![appStoreVersion isEqualToString:currentVersion]) { UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"版本有更新" message:[NSString stringWithFormat:@"检测到新版本(%@),是否更新?",appStoreVersion] delegate:self cancelButtonTitle:@"取消"otherButtonTitles:@"更新",nil]; [alert show]; } } - (void)alertView:(UIAlertView*)alertView clickedButtonAtIndex:(NSInteger)buttonIndex { if(buttonIndex==1) { //此处加入应用在app store的地址，方便用户去更新 NSString *iTunesLink = [NSString stringWithFormat:@"itms-apps://phobos.apple.com/WebObjects/MZStore.woa/wa/viewSoftwareUpdate?id=%@&mt=8",STOREAPPID]; [[UIApplication sharedApplication] openURL:[NSURL URLWithString:iTunesLink]]; } }
