I’m logging a bunch of data with NSLog(). Is there a way to capture the log data when my iPhone is not connected to my development machine and running under a debugger?
For example, can I redirect it to a file and then read the log file back through Xcode at a later point in time? I need to do this in order to test my app when the WiFi is poor, which necessitates that I go far away from my desk.
I’m pretty sure that NSLog() calls will be written to the system console log, so if you connect your iPhone to your computer after being offline, you should be able to look at the console log in XCode Organizer. The only caveat is that the console log is limited in size so older entries may be bumped off if you do a lot of logging.
