I have been using unfuddle which provided me with free 512 MB to use for my private projects, and (of course) GitHub for any opensource projects.

But what is better than setting up Git on your own server?

I have a $5/mth Digital Ocean VPS that is overloaded to run node apps, wordpress and mail server.. So, I might as well run GitLab too.

I had encountered TWICE, of Apple reviewers rejecting 2 of my apps because while testing, they encountered an error with Facebook login.

The errors they might have seen are:

com.facebook.sdk:SystemLoginCancelled

or

The user is not allowed to see this application per the developer set configuration.

or

Login failed with error code 800 error 800.

NSError is a very common and easy to use object in iOS.

But Parse has shown us how not to use it.

I faced the same problem as Jonathan with using the NSError emitted from Parse library.

Once again, Parse disappointed me with their developer support.

Their Anonymous User feature is a great feature, but it lacks the last 10% to be awesome.

When I was using the feature and did a query, it crashed.

One of the common errors when using CoreData is

*** Terminating app due to uncaught exception 'NSObjectInaccessibleException', reason: 'CoreData could not fulfill a fault for '0x10123456 <x-coredata://3E1F9B1C-46BE-49F8-A3ED-1234567BF0/Event/p42>

This is what happened:

Why would someone setup an email server when there is Gmail?

The reasons are plenty: Gmail (or Google Apps) for Business is no longer free. Outlook support for custom domains is no longer free. And why store your most important data on someone else server?

As described in Apple Autolayout Guide, your UIView animation block should look like this:

You can access a user calendar to insert new event, or to edit or delete.

Some code snippets:

I previously wrote about how to implement NSFetchedResultsController with Magical Record (UITableView version).

For UICollectionView, it is largely the same.

Except for the change that Apple did – there is NO [collectionView beginUpdates/endUpdates] methods.

Core Data is able to store binary data (NSData or UIImage) for an attribute.

And you can enable “Allows External Storage” to let Core Data manage the binary data eg. move it to external file if it hits a certain threshold.

However, a good rule of thumb as follows:
