一般会用来判断是否有新版本、是否需要强制更新

iOS的版本号，一个叫做Version，一个叫做Build，这两个值都可以在Xcode 中选中target，点击“Summary”后看到。 Version在plist文件中的key是“CFBundleShortVersionString”，和AppStore上的版本号保持一致，Build在plist中的key是“CFBundleVersion”，代表build的版本号，该值每次build之后都应该增加1。这两个值都可以在程序中通过下面的代码获得：

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

［2］具体实现
代码实现获得应用的Verison号：
[[[NSBundle mainBundle] infoDictionary] objectForKey:@"CFBundleShortVersionString"]或[[NSBundle mainBundle] objectForInfoDictionaryKey:@"CFBundleShortVersionString"];
获得build号：
[[[NSBundle mainBundle] infoDictionary] objectForKey:@"CFBundleVersion"]

打印出来infoDictionary的内容
    NSLog(@"%@",[[NSBundle mainBundle]infoDictionary]);
{
    BuildMachineOSBuild = 15B42;
    CFBundleDevelopmentRegion = en;
    CFBundleExecutable = "UIApplication\U7684\U4f7f\U7528";

iOS获取AppStore内应用程序信息

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

具体步骤如下：

1，用 POST 方式发送请求：

http://itunes.apple.com/search?term=你的应用程序名称&entity=software

更加精准的做法是根据 app 的 id 来查找：

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

/*
AFHTTPRequestOperationManager *mgr = [AFHTTPRequestOperationManager manager];

mgr.responseSerializer = [AFJSONResponseSerializer serializer];

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

NSLog(@"xxx");

//发送POST请求
[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");
//发送POST请求
[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);
}];
}
