iOS 跳转到Appstore的链接及二维码

1、应用内部跳转到Appstore

1、跳转到应用详情

[[UIApplication sharedApplication]openURL:[NSURL URLWithString:@"itms-apps://itunes.apple.com/app/id1061880281"]];

其中 @"itms-apps://itunes.apple.com/app/id1061880281"为拼接地址，1061880281为应用在Appstore注册上线时产生的唯一ID

2、跳转到评论

[[UIApplication sharedApplication]openURL:[NSURL URLWithString:@"itms-apps://itunes.apple.com/WebObjects/MZStore.woa/wa/viewContentsUserReviews?id=1232138855&pageNumber=0&sortOrdering=2&type=Purple+Software&mt=8"]];

注：由于iOS11对应用商店进行了重新设计，使用该链接在iOS11系统上会发现找不到应用。解决办法：判断系统版本，如果系统版本大于iOS11，跳转上1链接即可

2、扫描二维码跳转到appstore

https://itunes.apple.com/app/id1061880281 ,用这个地址生成二维码即可

但是有可能会碰到多国语言问题，你会发现在其他语言下用安卓设备扫描二维码会进入itunes,而默认展示出来的界面确是英文环境，这是你只需要在 https://itunes.apple.com/app/id1061880281 修改为如下：

例如中文：https://itunes.apple.com/cn/app/id1061880281

例如日文：https://itunes.apple.com/jp/app/id1061880281

等等...也就是在https://itunes.apple.com/后面加上国家的简写国际字符即可

3、检测新版本升级跳转到AppStore

注：这个功能只有写在应用每次启动时检测，如果在设置界面留有检测更新入口，上架时审核会被苹果拒绝，苹果是不允许在AppStore之外的方式升级的

-(void)checkVersion {

NSString *path = [[NSString alloc] initWithFormat:@"http://itunes.apple.com/lookup?id=%@",@"1061880281"];

NSURL *url = [NSURL URLWithString:path];

NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:url cachePolicy:NSURLRequestReloadIgnoringCacheData timeoutInterval:10];

　 [request setHTTPMethod:@"POST"];

NSOperationQueue *queue = [NSOperationQueue new];

[NSURLConnection sendAsynchronousRequest:request queue:queue completionHandler:^(NSURLResponse *response,NSData *data,NSError *error){

NSMutableDictionary *receiveStatusDic=[[NSMutableDictionary alloc]init];

if (data) {

NSDictionary *receiveDic = [NSJSONSerialization JSONObjectWithData:data options:NSJSONReadingMutableLeaves error:nil];

if ([[receiveDic valueForKey:@"resultCount"] intValue]>0) {

[receiveStatusDic setValue:@"1" forKey:@"status"];

[receiveStatusDic setValue:[[[receiveDic valueForKey:@"results"] objectAtIndex:0] valueForKey:@"version"]   forKey:@"version"];

}else{

[receiveStatusDic setValue:@"-1" forKey:@"status"];

}

}else{

[receiveStatusDic setValue:@"-1" forKey:@"status"];

}

[self performSelectorOnMainThread:@selector(receiveData:) withObject:receiveStatusDic waitUntilDone:NO];

}];

}

- (void)receiveData:(id)sender {

NSString *serverVersion = [sender objectForKey:@"version"]; //获取版本号

//获取应用当前版本

NSString *currentVersion = [[[NSBundle mainBundle] infoDictionary] objectForKey:@"CFBundleShortVersionString"];

// 服务器版本号大于当前版本号

if ([serverVersion compare:currentVersion options:NSNumericSearch] == NSOrderedDescending) {

// 有新版本，执行升级操作

} else {

　　// 没有检测到新版本

}

}
