传入APPID 到此 https://itunes.apple.com/lookup?id=794869798 苹果会返回关于APP的json数据，如下所示

做了一个iOS下的App，普通情况下，AppStore会提示更新的，但是用户如果没开推送，或者不打开AppStore，是不知道有新版本的，所以要做版本更新提醒，当AppStore上有新的版本时，提示用户进行更新。如何关键是如何获得AppStore上的版本信息，可以通过苹果提供的REST接口进行查询。REST接口如下

http://itunes.apple.com/lookup?id=appid;

用自己的appid替换id的内容，就可以得到一个json的内容，内容很明了，一看就知道了，其中有一个版本信息，还有相应的更新信息，app地址等等。

顺便说一下如何获得本产品的版本信息。

NSString* thisVersion = [[NSBundle mainBundle] objectForInfoDictionaryKey: (NSString*)kCFBundleVersionKey];

可以参照下面的代码

https://github.com/jacobsologub/appdate

跳转到AppStore产品页，直接得到json中的trackViewUrl，通过下面的方式跳转过去。

NSURL * url = [NSURL URLWithString:itunesURL];//itunesURL = trackViewUrl的内容

[[UIApplication sharedApplication] openURL:url];

／／／／／／／／／／／／／／／／／／／／／／／／／／／／／／／／／／／／／／／／／／／／／／／／／／／／／

-(void)checkVersion

{

NSURL *url = [NSURL URLWithString:MY_APP_URL];

NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:url];

[request setHTTPMethod:@"GET"];

[request setTimeoutInterval:10.0];

NSOperationQueue *queue = [[NSOperationQueue alloc]init];

[NSURLConnection sendAsynchronousRequest:request

queue:queue

completionHandler:^(NSURLResponse *response, NSData *data, NSError *connectionError) {

if (connectionError) {

}

else {

NSError* jasonErr = nil;

// jason 解析

NSDictionary* responseDict = [NSJSONSerialization JSONObjectWithData:data options:NSJSONReadingAllowFragments error:&jasonErr];

if (responseDict && [responseDict objectForKey:@"results"]) {

NSDictionary* results = [[responseDict objectForKey:@"results"] objectAtIndex:0];;

if (results) {

CGFloat fVeFromNet = [[results objectForKey:@"version"] floatValue];

strVerUrl = [results objectForKey:@"trackViewUrl"];

if (0 < fVeFromNet && strVerUrl) {

CGFloat fCurVer = [[[[NSBundle mainBundle] infoDictionary] objectForKey:@"CFBundleVersion"] floatValue];

if (fCurVer < fVeFromNet) {

dispatch_async(dispatch_get_main_queue(), ^{

UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"版本更新"

message:@"发现一个新版本，立即去更新吧！"

delegate:self

cancelButtonTitle:@"不了，谢谢"

otherButtonTitles:@"立即更新", nil];

[alert show];

});

}

}];

}

#define MY_APP_URL @"http://itunes.apple.com/lookup?id=794869798"
