Instance Method

waitForDataInBackgroundAndNotifyForModes:

Asynchronously checks to see if data is available.

Declaration

- (void)waitForDataInBackgroundAndNotifyForModes:(NSArray<NSRunLoopMode> *)modes;

Parameters

modes: The runloop modes in which the data available notification can be posted.

Discussion

When the data becomes available, this method posts a NSFileHandleDataAvailableNotification notification on the current thread. This method differs from waitForDataInBackgroundAndNotify in that modes specifies the run-loop mode (or modes) in which NSFileHandleDataAvailableNotification can be posted.

You must call this method from a thread that has an active run loop.
