BigBrother
BIG BROTHER IS WATCHING YOU.
BigBrother is a Swift library made for iOS that automatically watches for any performed request and sets the network activity indicator.
This is mostly a proof of concept, having several limitations because of how NSURLProtocol
works. Some of them are:
NSURLProtocol
doesn't inheritNSURLSession
's configured headers (see https://github.com/Alamofire/Alamofire/issues/473)NSURLProtocol
isn't compatible with authentication APIs (see https://github.com/marcelofabri/BigBrother/issues/2)
It was inspired by this comment by Mattt Thompson.
It also was based on this tutorial for creating an NSURLProtocol
and on AFNetworkActivityIndicatorManager
from AFNetworking.
Usage
Adding
NSURLConnection
and NSURLSession.sharedSession()
Adding to BigBrother.addToSharedSession()
NSURLSessionConfiguration
Adding to a custom var configuration = NSURLSessionConfiguration.defaultSessionConfiguration()
BigBrother.addToSessionConfiguration(configuration)
let session = NSURLSession(configuration: configuration)
Removing
NSURLConnection
and NSURLSession.sharedSession()
Removing from BigBrother.removeFromSharedSession()
NSURLSessionConfiguration
Removing from a custom var configuration = NSURLSessionConfiguration.defaultSessionConfiguration()
BigBrother.removeFromSessionConfiguration(configuration)
let newSession = NSURLSession(configuration: configuration)
It is important to configure your NSURLSessionConfiguration object appropriately before using it to initialize a session object. Session objects make a copy of the configuration settings you provide and use those settings to configure the session. Once configured, the session object ignores any changes you make to the NSURLSessionConfiguration object. If you need to modify your transfer policies, you must update the session configuration object and use it to create a new NSURLSession object.
Advanced usage
BigBrother.URLProtocol
is an NSURLProtocol
subclass that manages the network activity indicator and it's public if you want to add it yourself to an NSURLSessionConfiguration
or to the default NSURLProtocol
(used by NSURLConnection
and NSURLSession.sharedSession()
).
BigBrother.Manager
is also public, so you can manage the network activity indicator directly:
BigBrother.Manager.sharedInstance.incrementActivityCount()
// do something...
BigBrother.Manager.sharedInstance.decrementActivityCount()
Installation
BigBrother is available through CocoaPods. To install it, simply add the following line to your Podfile:
pod 'BigBrother'
Then run pod install
with CocoaPods 0.36 or newer.
Unit Tests
Unit testing is done with XCTest
and the tests are available under the BigBrotherTests folder.
