How to check the stability of these applications during development?

Question

My question is related to the following three questions.

• iPhone What happens to previous data when an application is updated to a new version

• How iPhone app updates work

• Prevent user data from being erased when updating an iOS application via iTunes

Here are my 2 questions.

• Should I create the Documents directory manually in the file system or only create a “group” in xcode, so that when the application is updated, will the data remain persistent?

• How can I check the stability of an application during application development on a simulator or on an iPhone?

Thank.

Answer 1

• None. A document catalog is created for you when your application is installed. You can get the path to it using:

  NSString *docuDir = nil;
  NSArray *list = NSSearchPathForDirectoriesInDomains(
          NSDocumentsDirectory, NSUserDomainMask, YES/*expand tilde*/);
  if ([list count]) docuDir = [list objectAtIndex:0U];
  

• As @Ben said, the directory is only deleted when the application is uninstalled explicitly (remove it from Springboard). When you create and run, Xcode effectively updates your application in place. If everything is intact (and there is no reason not to be), you should be fine.
