Hi all,
I've been programming Cocoa for a couple months now, but getting
really into it the last 2 or 3 weeks. I've got this program which
generates a random number in a specified interval, and writes that
number, and the next 100 or so numbers above it. It needs to write all
these numbers to a file, each on its own line. What I do now is create
an NSMutableArray to hold all the numbers, and then [numArray
writeToFile: numFileLocation atomically:YES]. This works... it creates
the file and the data is in there, but I (and my users!) would rather
have just a plain text file with one number on each line instead of
this XML file.
I did some research and found a lot of stuff about NSFileHandle,
NSFileManager and NSData but I couldn't figure out the best way to do
this. Can someone point me in the right direction? Thanks!
NSString *path; // fill these in however you like.
NSMutableArray *numArray;
size_t someBigNumber = 500; // doesn't *really* matter how big this
is, it will grow if needed.
NSMutableString *results = [NSMutableString
stringWithCapacity:someBigNumber];
NSEnumerator *items = [myArray objectEnumerator];
id thisItem;
while (thisItem = [items nextObject])
{
[results appendString:[thisItem stringValue]];
[results appendString:@"\n"];
}
[results writeToFile:path atomically:YES];
Hope this helps,
