- 1. OHOH
- 2. About Me • iOS developer • Runs Azukisoft Pte Ltd • Author of http://www.amazon.com/Objecti ve-C-Memory-Management- Essentials-Gibson- ebook/dp/B00V8BMX7I/
- 3. What is OHOH? • iOS social networking app • Like Meetup.com • But for smaller groups
- 5. Functionality • Private chats • Group chats • Likes • Comments • Push notifications
- 6. Technology Stack • Objective-C • Cocoapods • AFNetworking • Parse for Push Notification • Firebase/Layer
- 7. Objective-C • Why use Objective-C? • Last year Swift was not yet mature • Legacy code was still in Obj-C • No point switching to Swift
- 9. CocoaPods • Has a huge library of supported components • But tends to break when new version of Xcode is released • Am looking into alternatives e.g Carthage
- 11. Parse • Only for push notifications • Easy to set up and test • Tried Urban Airship, but had problem with missing push notifications • Parse has not failed us. YET!!!
- 12. Private Chat/Group Chat • Firebase for Chat • Firebase good for real time use cases • Chat is 1 of them • But Firebase is not dedicated for chat
- 13. Private Chat/Group Chat • So additional chat functionalities such as image upload is not supported • It was a hassle managing data from between our DB and Firebase
- 15. Private Chat/Group Chat • Switched to Layer • But as with all cutting edge tech • Code examples do not work out of the box • 50% of their sample code have to be modified
- 16. Private Chat/Group Chat • Layer is developed purely to create chat apps • So image upload, video upload is all supported • But can be a bit slow at time
- 18. AFNetworking • Most popular iOS networking library we have seen so far • Widely used • Widely supported • But still have issues
- 19. AFNetworking • Issue due to Apple’s NSURL implementation • Causes operation time outs even if network is ok • https://github.com/AFNetworking/ AFNetworking/issues/2314
- 20. AFNetworking • Also sometimes we have multiple alertviews about network errors • Anyone encountered such errors before?
- 21. Backend • Typical LAMP stack • PHP as fast to get going • MySQL as it is the standard • Running on Linode • Ubuntu 14.04
