readToEndOfFileInBackgroundAndNotify()
Reads to the end of file from the file or communications channel in the background and posts a notification when finished.
Declaration
func readToEndOfFileInBackgroundAndNotify()Discussion
This method performs an asynchronous readToEndOfFile operation on a file or communications channel and posts an NSFileHandleReadToEndOfFileCompletion. You must call this method from a thread that has an active run loop.
The notification includes a userInfo dictionary that contains the data read; access this object using the NSFileHandleNotificationDataItem key.
Any object interested in receiving this data asynchronously must add itself as an observer of NSFileHandleReadToEndOfFileCompletion. In communication via stream-type sockets, the receiver is often the object returned in the userInfo dictionary of NSFileHandleConnectionAccepted.
