Using User Interest

User Interest Listener

When receiving GFPNativeAd, Delegate could be linked to learning when the user expressed interest (1-second exposure of 100% of advertising section by SDK definition) and when the interest disappeared (exposure of 0% of advertising section by SDK definition).

The usage method is as follows:

Swift

nativeAd.userInterestDelegate = self

Objective-C

nativeAd.userInterestDelegate = self;

Swift

func ad(_ ad: NSObject!, didChangeUserInterest userInterest: Bool) {
    if userInterest == true {
        // 1-second exposure of 100% of advertising section by SDK definition            
    } else {
        // exposure of 0% of advertising section by SDK definition 
    }
}

Objective-C

- (void)ad:(NSObject *)ad didChangeUserInterest:(BOOL)userInterest {
    if (userInterest) {
        // 1-second exposure of 100% of advertising section by SDK definition
    } else {
        // exposure of 0% of advertising section by SDK definition
    }
}
