This tutorial will give an example of how to add a custom font to your iOS app that you can use in UIFont, UILabel, UITextView, etc.

1. Open Info.plist
2. Right click and choose “Add Row”.
3. Start typing and select “Fonts provided by application”.
4. Expand the row and next to Item 0 in the Value field enter the name of the font.
5. Don’t forget to add the font file to your project and set its target.  You can place it in a new folder called “Resources”.

When designing a database schema you often have to make decisions on a fields length. Rather then just guess at a number, use the maximum possible value that could conceivably be used for the field. Below is a chart of common database fields such as email address, city, zip code and country name and the maximum possible length value that can be used.

If you are using Amazon Simple Email Service via AWS you can make your emails appear more professional by setting the from name to either a person or company name instead of just the from email address.

To accomplish this via the command line, SDK, or API simply replace the source email address “[email protected]” with “Company Name [email protected]”.
