Mr. Samesh Swongamikha and Mr. Neetin Sharma gave

1. iOS App Development
Presented By:
Samesh Swongamikha & Neetin Sharma

2. Design Patterns
• Loosely based on mvc
• Massive view controller

3. MVVM Pattern
• Model – View –ViewModel

4. The communication pattern
• Direct

• NSObjectContext
• Class Interface

6. Database optimization
• Normalization
• No images
• Extensions

7. Schema-less DB
• Why go schema-less ?
• Parse

8. Networking
• Why do we need web server’s data in iOS?
• What kind of data we can get from server?
• JSON or XML or something else?
• What kind of server API we need?
• RESTful API , any other?

9. Networking continued
• Do we need our own server?
• use BAAS, for e.g. Parse

10. Networking continued
• API for server request
• NSURLConnection
• NSURLSession (iOS 7 on wards)
• AFNetworking (third party)
• Alamofire (written in swift)

11. Networking continued
• Use asynchronous server request (do not block main thread).
• Use background thread for downloads and uploads.
• Don’t store large size image in disk/database but curl when needed in the background using
background thread.
• Do not initiate heavy downloads on mobile data, check if device is using wifi.

12. Memory Management
• Retain/Release
• ARC
• Be careful (Outlets/ Popovers/ Timers)

13. Swift
• What is swift?
• What is new in swift?
• It is designed for type safety
• Tuples
• Generics
• Memory is managed automatically.
• Functional programming pattern. e.g. Filters.
• Functions are first class objects.

14. Useful tools/ links
• Cocoapods (http://cocoapods.org/)
