  • ios应用, 设置不自己主动备份到iCloud

    原创文章,转载请注明出处

    ios项目,假设有内置下载或者程序动态生成文件的话,就要注意所下载或生成的文件,要不要自己主动备份到iCloud

    假设没有合适的理由就自己主动上传大文件的话,可能在不能通过应用审核. 收到一下类似这种答复

    We also found that your app does not follow the iOS Data Storage Guidelines, which is required per the App Store Review Guidelines.

    比如有人遇到相同问题 http://stackoverflow.com/questions/16239147/ios-do-not-back-up-attribute

    苹果给出的设置方法:官方文档 https://developer.apple.com/Library/ios/qa/qa1719/_index.html

    应用到项目中, 详细代码例如以下

    #define DownLoad_Directory "Download_Dir"
    
    #pragma mark Download_Dir
    void DeviceClass::initDownloadDir(){
        string l_strDocumentDir = cocos2d::CCFileUtils::sharedFileUtils()->getWritablePath();
        l_strDocumentDir.append(DownLoad_Directory);
        
        NSString* l_strDownloadDir = [NSString stringWithUTF8String:l_strDocumentDir.c_str()];
        NSError* l_error;
        if (![[NSFileManager defaultManager] fileExistsAtPath:l_strDownloadDir]){
            [[NSFileManager defaultManager] createDirectoryAtPath:l_strDownloadDir withIntermediateDirectories:NO attributes:nil error:&l_error]; //Create folder
            
            // exclude downloads from iCloud backup
            NSURL *url = [NSURL fileURLWithPath:l_strDownloadDir];
            if(strcmp(g_systemVersion.c_str(), "5.1") >=0 ){
                if ([url setResourceValue:[NSNumber numberWithBool:YES] forKey:NSURLIsExcludedFromBackupKey error:&l_error] == NO) {
                    NSLog(@"Error: Unable to exclude l_strDownloadDir from backup: %@", l_error);
                }
            }
        }
        
        //this->setDonotBackupInICloud();
    }
    就是在可写文件夹下建立一个新文件夹, 存放下载文件(须要的话,自己主动生成的文件也放到这), 并标记这个文件夹不会被上传到iCloud

    感谢梅俊同事的提醒


    測试方法:

    设置->iCloud->管理储存空间->备份(假设有多设备的话,选择设备)

    应用多的话,点击"显示全部应用" 查到你的应用,在iCloud上备份内容的总容量.

    打开和关闭这个接口, 会发现, 你的应用在iCloud上的备份mwjg容量是不是一样.
