Usually, you learned the “hello world” from textbooks and started to explore the “real world”. While you were having fun, you also ran into many challenges that were not covered by the textbooks. Examples could be detecting network connectivity, using custom fonts, dealing with input fields and showing/hiding keyboard, source controlling, making decision on choosing backend, etc.
This book is here to help you take on those challenges. Hope you find it helpful.
All examples are compatible with iOS6 and run well on iPhone 5.
