Question

ok i’ve been going round in circles for 1.5 hours, now i need some help. below is the code i’m using to create a list of files in my Documents Directory, all works fine unless the directory is empty.

fileList = [[NSFileManager defaultManager] contentsOfDirectoryAtPath:documentsDirectory error:&error];

what can i do directly before this to check if the directory has contents?

ive tried

if ([[[NSFileManager defaultManager] contentsOfDirectoryAtPath:documentsDirectory error:&error] objectAtIndex:0]){
fileList = [[NSFileManager defaultManager] contentsOfDirectoryAtPath:documentsDirectory error:&error];
}

but that also crashes the app

/////////////////////NOOB MISTAKE ALERT////////////////////

ok my problem was my next line of code

NSLog(@"fileList: %@",[fileList objectAtIndex:fileList.count-1]);

that’s what was crashing my app, my own fault i admit lol. [fileList objectAtIndex:fileList.count-1] is out of bounds, i’m confused as to why the debugger didn’t tell me that much.

Thanks for your help guys

Answer 1

The method should not crash even if there is no files. According to the doc,

... Returns an empty array if the directory exists but has no contents.

I would check

• If the documentsDirectory variable is properly set as a NSString instance
• If the documentsDirectory variable is not deallocated already

NSLogging documentsDirectory just before the call would be the right first step.
