Bucket 購読の有無は次のように確認できます。

Swift:

// Instantiate the target bucket.
let bucket = Kii.bucket(withName: "_target_bucket_")

do{
  // Check if the current user is subscribed to the bucket.
  try KiiUser.current()!.pushSubscription().checkIsSubscribedSynchronous(bucket)
}catch(let error as NSError){
  print("The current user is not subscribed to the bucket.");
}
print("The current user is subscribed to the bucket.");

// Instantiate the target bucket.
let bucket = Kii.bucket(withName: "_target_bucket_")

// Check if the current user is subscribed to the bucket.
KiiUser.current()!.pushSubscription().checkIsSubscribed(bucket) { (retBucket : KiiSubscribable , subscribed : Bool, error : Error?) -> Void in
  if error != nil {
    // Handle the error.
    return
  }

  if (subscribed) {
    print("The current user is subscribed to the bucket.");
  } else {
    print("The current user is not subscribed to the bucket.");
  }
}

Objective-C:

NSError *error = nil;

// Instantiate the target bucket.
KiiBucket *bucket = [Kii bucketWithName:@"_target_bucket_"];

// Check if the current user is subscribed to the bucket.
BOOL subscribed = [[KiiUser currentUser].pushSubscription checkIsSubscribedSynchronous:bucket
                                                                                 error:&error];
if (subscribed) {
  NSLog(@"The current user is subscribed to the bucket.");
} else {
  if (error.kiiHttpStatus == 404) {
    NSLog(@"The current user is not subscribed to the bucket.");
  } else {
    // Handle the error.
    return;
  }
}

// Instantiate the target bucket.
KiiBucket *bucket = [Kii bucketWithName:@"_target_bucket_"];

// Check if the current user is subscribed to the bucket.
[[KiiUser currentUser].pushSubscription checkIsSubscribed:bucket
                                                    block:^(id<KiiSubscribable> subscribable, BOOL subscribed, NSError *error) {
  if (subscribed) {
    NSLog(@"The current user is subscribed to the bucket.");
  } else {
    if (error.kiiHttpStatus == 404) {
      NSLog(@"The current user is not subscribed to the bucket.");
    } else {
      // Handle the error.
      return;
    }
  }
}];
