Code blocks is a powerful way to run custom logic for different variations. For tests which are not based on the existing variables of your app, code block offers a developer-friendly approach to test different variations.
The VWO SDK identifies a test by its campaign key. The campaign key should match the key you created while setting up the A/B test on the VWO web portal.
The variationName
function returns the name of the variation you created on the VWO web portal.
NSString *variationName = [VWO variationNameForTestKey:@"campaign_key"];
if ([variationName isEqualToString:@"Control"]) {
// Code for Control
} else if ([variationName isEqualToString:@"Variation 1"]) {
// Code for Variation 1
} else {
}
if let variation = VWO.variationNameFor(testKey: "campaign_key") {
switch variation {
case "Control":
// Code for Control
break
case "Variation 1":
// Code for Variation 1
break
default: break
}
}
The variation name should match the name you used on the VWO web portal.
Use the last else or default section to code the behavior of your app if this A/B test is not running.
If your control and default behaviors are the same, you can remove the control condition.
