iOS 如何实现实时版本更新

虽然苹果禁止应用内更新，但是有时候仍需要弹出更新提示。但是iOS审核需要时间，如何实时获取信息判断是否更新呢。我们可以获取App Store中app的信息来判断。代码如下：

- (void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event{//1.直接请求苹果商店信息[self getAppStoreAppInfoWithAppID:APPID];

}- (void)getAppStoreAppInfoWithAppID:(NSString *)appId {

AFHTTPSessionManager*manager =[AFHTTPSessionManager manager];//可不写[manager.responseSerializer setAcceptableContentTypes: [NSSet setWithObjects:@"application/json",@"text/json",@"text/javascript",@"text/html", nil]];//必传信息NSDictionary*dict = @{@"id":appId};//此处的Apple ID[manager POST:@"https://itunes.apple.com/lookup"parameters:dict progress:^(NSProgress *_Nonnull uploadProgress) {

} success:^(NSURLSessionDataTask * _Nonnull task,id_Nullable responseObject) {

NSArray*array = responseObject[@"results"];if(array.count !=0) {//先判断返回的数据是否为空NSDictionary*dict = array[0];

NSDictionary*infoDic =[[NSBundle mainBundle] infoDictionary];

NSString*currentAppVersion = infoDic[@"CFBundleShortVersionString"];

NSString*newVersion =[NSString stringWithFormat:@"%@版本更新",dict[@"version"]];//也可以判断不一样就行。那样简单if([dict[@"version"] compare:currentAppVersion options:NSNumericSearch] ==NSOrderedDescending) {

NSLog(@"需要更新");

}else{

NSLog(@"不需要更新");

}

}

} failure:^(NSURLSessionDataTask * _Nullable task, NSError *_Nonnull error) {

}];

}

返回结果图如下：
