Google Analytics for Mobile Apps iOS SDK v3事件跟踪

Question

I'm using Google Analytics for Mobile Apps iOS SDK v3 . Screen tracking is working fine, but I cant get event tracking to work. Xcode shows error:

No known class method for selector 'createEventWithCategory:withAction:withLabel:withValue:'

My code is:

- (IBAction)callButton:(id)sender {
[[UIApplication sharedApplication] openURL:[NSURL URLWithString:@"tel:12345"]];
id<GAITracker> tracker = [[GAI sharedInstance] defaultTracker];    
[tracker send:[[GAIDictionaryBuilder createEventWithCategory:@"ui_action"
                                                  withAction:@"button_press"
                                                   withLabel:@"play_button"
                                                   withValue:nil] build]];
}

Answer 1

Try:

[tracker send:[[GAIDictionaryBuilder createEventWithCategory:@"ui_action"
                                                      action:@"button_press"
                                                       label:@"play_button"
                                                       value:nil] build]];
