UIActivityViewControllerでのユーザーアクションをトラッキングする

細かくやろうとするといろいろ面倒だった。カテゴリ作って今後も使いまわそう。で、そのカテゴリ貼っておく。どうぞ。

使い方

completionWithItemsHandlerをUIActivityViewControllerにぶち込むときにcompletionWithItemsHandlerAndTrackingに対してぶち込むだけでトラッキング用のコードを追加してくれるよ。

例えばこんな感じに。

UIActivityViewController *activityViewController = [[UIActivityViewController alloc] initWithActivityItems:@[imageView.image] applicationActivities:@[[LKLineActivity new]]];
activityViewController.completionWithItemsHandlerAndTracking = ^(NSString *activityType, BOOL completed, NSArray *returnedItems, NSError *activityError) {
    if (activityError) DDLogError(@"%@", activityError);
    else if (completed) DDLogInfo(@"action completed: %@", activityType);
};
[self presentViewController:activityViewController animated:YES completion:nil];

LINEが追加されているのはお好みで。
Cocoapodsで入手出来るLineKitがこの前のバージョンアップでLINEのためのUIActivityのサブクラスが追加されて便利になってた。

とくにブロックの中でやることがなければ

activityViewController.completionWithItemsHandlerAndTracking = nil;

だけでもおｋ。
