Flagstaff is a simple feature flagging framework built in Objective-C.

Installation

Flagstaff is available through CocoaPods. To install it, simply add the following line to your Podfile:

pod 'Flagstaff', '~> 0.1'

Using Flagstaff

First, you need remote flags to use. Flags must follow the flagstaff v1 schema. For development purposes, the simplest way to do this is to upload json files to a server and use a url format similar to the following:

FSFlagManager *flagManager = [[FSFlagManager alloc] initWithURLFormat:@"https://example.com/flags/{flag}.json"];

// Check if a flag is enabled
if ([flagManager enableFeatureForKey:@"flag_name"]) {
    // The flag is enabled
} else {
    // The flag is disabled
}

// Get custom parameters for key
NSDictionary *parameters = [flagManager parametersForKey:@"flag_name"];
NSInteger parameterValue = [[parameters objectForKey:@"param_name"] integerValue];
