If you are deploying files with your Delphi XE8 Firemonkey apps to IOS in the Startup\Documents directory and you do not want or need them backed up to Icloud there is a code snippet you can use to turn off the backup flag. I found this code over on the German Delphi forum. The flag under IOS is called NSURLIsExcludedFromBackupKey and the Apple docs are here. You can find out more about when and how you should use this no backup flag over on StackOverflow. One example of usage is if you have a large SQLite file that you are deploying with the app and you have no need for it to backup to Icloud then you can apply this flag to the file when your app is run for the first time. This code snippet should also work with Appmethod. Here is the code snippet:
function SetBackupFlag(AFileName: string; ABackup: boolean): boolean;
URL : NSUrl;
Err : PPointer;
URL := TNSURL.Wrap(TNSURL.OCClass.fileURLWithPath(NSStr(AFileName)));
result := URL.setResourceValue(TNSNumber.OCClass.numberWithBool(not ABackup), NSStr('NSURLIsExcludedFromBackupKey'), err) and (err = nil);
