I'm getting an intermittent infinite loop in the simulator that I
can't seem to reproduce.
Both on the simulator and the device, the problem unfolds like this:
The app goes into its loop and begins filling up all available memory
with something or other. I press the Home button to terminate. Then
afterwards the application refuses to restart: I have to recompile and
put it back on the simulator or device.
I did a sample with Activity Monitor while the app was doing its
infinite loop in the simulator. If I understand the output, it happens
in a method that's parsing a string. So of course I'm looking at that
part of the code closely. But the infinite loop occurs only
infrequently, and I can't reproduce it, even with exactly the same
string input.
Any idea why the app is refusing to restart? This is what I get in the
Apple report:
Exception Type: EXC_BREAKPOINT (SIGTRAP)
Exception Codes: 0x0000000000000002, 0x0000000000000000
Crashed Thread: 0
Application Specific Information:
iPhone Simulator 3.0 (138), iPhone OS 2.2.1 (5H11)
*** Terminating app due to uncaught exception
'NSInvalidArgumentException',
reason: '*** -[UITableViewCell initWithStyle:reuseIdentifier:]:
unrecognized selector sent to instance 0x530f10'
Does this mean that the message listed is being sent to something that
isn't a UITableViewCell? Is there away I can use that instance number
to track down that something?
There are two small XML files that store data in the Documents
directory. I've had a look at them, and they've not been corrupted. In
any case, I've coded the app to reset itself if it can't load those
data files. (My understanding is that arrayWithContentsOfFile: won't
load the data if the XML can't be parsed properly.)
As always, any help is much appreciated.
