What is OHOH?
• iOS social networking app• Like Meetup.com• But for smaller groups
Functionality
• Private chats• Group chats• Likes• Comments• Push notifications
Technology Stack
• Objective-C• Cocoapods• AFNetworking• Parse for Push Notification• Firebase/Layer
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
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
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!!!
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
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
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
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
AFNetworking
• Most popular iOS networking library we have seen so far• Widely used• Widely supported• But still have issues
AFNetworking
• Issue due to Apple’s NSURL implementation• Causes operation time outs even if
network is ok• https://github.com/AFNetworking/
AFNetworking/issues/2314
AFNetworking
• Also sometimes we have multiple alertviews about network errors• Anyone encountered such errors
before?
Backend
• Typical LAMP stack• PHP as fast to get going• MySQL as it is the standard• Running on Linode• Ubuntu 14.04
