根据bundle ID获取App Store的APP信息(可用来检测新版本,可以不考虑APP ID了)

首先,自问自答:

问:为什么不使用APP ID呢?

答:APP ID没有保存在 -info.plist 文件,不方便嘛。Bundle ID 保存在 -info.plist文件。

我要做通用性的功能,所以,查找时,以Bundle ID做搜索条件。


下面,搜索APP信息:

(1 ) 这是很重要的:

(千万要注意:下面的bundleId必须写成bundleId,不能写成 bundleid或者bundleID)

http://itunes.apple.com/lookup?bundleId=你APP的Bundle ID



(2) 如果找到了,返回json格式的数据:

比如:


{
 "resultCount":1,
 "results": [
{"kind":"software", "features":[], 
"supportedDevices":["iPhone5s", "iPhone4", "iPadFourthGen", "iPadWifi", "iPadFourthGen4G", "iPodTouchourthGen", "iPad2Wifi", "iPhone4S", "iPadMini4G", "iPhone-3GS", "iPhone5", "iPodTouchFifthGen", "iPhone5c", "iPad3G", "iPadThirdGen4G", "iPadMini", "iPodTouchThirdGen", "iPadThirdGen", "iPad23G"], "isGameCenterEnabled":false, "screenshotUrls":["http://a2.mzstatic.com/us/r30/Purple6/v4/65/d9/f4/65d9f4c8-83aa-aedc-7d33-17bfcd95f329/screen1136x1136.jpeg"], "ipadScreenshotUrls":[], "artworkUrl60":"http://a637.phobos.apple.com/us/r30/Purple/v4/f9/c6/d2/f9c6d227-bab9-3008-88b6-ea74e48510a7/57.png", "artworkUrl512":"http://a157.phobos.apple.com/us/r30/Purple4/v4/c7/77/dd/c777dd5f-a1c2-e0fa-6a6f-1c4e3db98c12/mzl.tqbteywq.png", "artistViewUrl":"https://itunes.apple.com/us/artist/shenzhen-reecam-tech.-ltd./id479468962?uo=4", "artistId":479468962, "artistName":"Shenzhen Reecam Tech.

}

版本号:找到那个"version",它的值就是版本号

URL:找到那个“trackViewUrl", 它的值就是介绍这个APP的链接网址

你可以对比本地APP的版本号和APP Store上发布的版本号,如果有新版本,可以提示用户要更新...


(3)如果没找到:

{
 "resultCount":0,
 "results": []
}


(4)这里顺便告诉大家用 JSONKit 取出版本号,

//注意:这里是示例,用阻塞操作,不考虑异常情况

//下面读取的是本地APP的Bundle ID:

NSString* bundleID = [[NSBundle mainBundle] objectForInfoDictionaryKey: (NSString*) kCFBundleIdentifierKey];

NSString* strURL = [ NSString stringWithFormat:@"http://itunes.apple.com/lookup?bundleId=%@",bundleID ];

NSData* data = [ NSData dataWithContentsOfURL:[ NSURL URLWithString: strURL ]];

NSDictionary* dic = [data objectFromJSONData ];

NSArray* resultArray = [ dic objectForKey:@"results"];

NSDictionary* subDict = [resultArray objectAtIndex: 0 ];
NSString* strVersion = [subDict objectForKey: @"version"];

这个strVersion就是版本号啦
