通常會用來判斷是否有新版本、是否須要強制更新

iOS的版本號，一個叫作Version，一個叫作Build，這兩個值均可以在Xcode 中選中target，點擊「Summary」後看到。 Version在plist文件中的key是「CFBundleShortVersionString」，和AppStore上的版本號保持一致，Build在plist中的key是「CFBundleVersion」，表明build的版本號，該值每次build以後都應該增長1。這兩個值均可以在程序中經過下面的代碼得到：

[[[NSBundle mainBundle] infoDictionary] valueForKey:@"key"]


［2］具體實現
代碼實現得到應用的Verison號：
[[[NSBundle mainBundle] infoDictionary] objectForKey:@"CFBundleShortVersionString"]或[[NSBundle mainBundle] objectForInfoDictionaryKey:@"CFBundleShortVersionString"];
得到build號：
[[[NSBundle mainBundle] infoDictionary] objectForKey:@"CFBundleVersion"]



打印出來infoDictionary的內容
    NSLog(@"%@",[[NSBundle mainBundle]infoDictionary]);

    BuildMachineOSBuild = 15B42;

iOS獲取AppStore內應用程序信息

參考 apple的文檔：www.apple.com/itunes/affiliates/resources/documentation/itunes-store-web-service-search-api.html

具體步驟以下：

1，用 POST 方式發送請求：

http://itunes.apple.com/search?term=你的應用程序名稱&entity=software

更加精準的作法是根據 app 的 id 來查找：

http://itunes.apple.com/lookup?id=你的應用程序的ID

/*
AFHTTPRequestOperationManager *mgr = [AFHTTPRequestOperationManager manager];

mgr.responseSerializer = [AFJSONResponseSerializer serializer];

mgr.responseSerializer.acceptableContentTypes = [NSSet setWithObject:@"text/javascript"];

NSLog(@"xxx");

//發送POST請求
[mgr POST:@"http://itunes.apple.com/search?term=QQ&entity=software" parameters:nil  success:^(AFHTTPRequestOperation *operation, id responseObject) {
    NSLog(@"%@",responseObject);
} failure:^(AFHTTPRequestOperation *operation, NSError *error) {
    NSLog(@"%@",error);
}];

AFHTTPRequestOperationManager *mgr1 = [AFHTTPRequestOperationManager manager];
mgr1.responseSerializer = [AFJSONResponseSerializer serializer];
mgr1.responseSerializer.acceptableContentTypes = [NSSet setWithObject:@"text/javascript"];
NSLog(@"xxx");
//發送POST請求
[mgr1 POST:@"http://itunes.apple.com/lookup?id=com.tenpay.mobile.iphone" parameters:nil  success:^(AFHTTPRequestOperation *operation, id responseObject) {
    NSLog(@"%@",responseObject);
} failure:^(AFHTTPRequestOperation *operation, NSError *error) {
    
    NSLog(@"%@",error);
}];
}
