    Declaration

    func alertError(message: String?, title: String?, optInActions: [UIAlertAction]? = nil, completion: (() -> Void)? = nil)

  • Undocumented

    Declaration

    Swift

    func setupErrorAlert(
	title: String? = nil,
	message: String,
	okTitle: String? = nil,
	secondaryActionTitle: String? = nil,
	completion: (() -> Void)? = nil,
	secondaryActionCompletion: (() -> Void)? = nil
) -> UIAlertController

  • This method checks whether the below conditions in regards to background fetching have been met and creates the corresponding alert. Note that store is needed in the alert closure in order to track that the alert has already been shown once. The error alert should only be shown:

    • once
    • if the background refresh is disabled
    • if the user is not in power saving mode, because in this case the background refresh is disabled automatically. Therefore we have to explicitly check this.

    Declaration

    Swift

    func createBackgroundFetchAlert(
	status: UIBackgroundRefreshStatus,
	inLowPowerMode: Bool,
	hasSeenAlertBefore: Bool,
	store: Store) -> UIAlertController?
