Question

I have a txt file with some URLs like this

http://url1.com

http://url1.com

http://url1.com

Separated by a line break. How could I add those as different entries separated by line breaks to an NSMutableArray? Thanks 🙂

Answer 1

NSString *myListString = /* load / download file */
NSMutableArray *myList = [myListString componentsSeparatedByString:@"\n"];

You may have to use <br/> if it’s HTML.

@octy’s solution is only available in iOS 4.0 or later. This solution is iOS 2.0 or later. You can check the iOS version and choose which one to use:

BOOL useEnumeratedLineParsing = FALSE;
NSString *reqSysVer = @"4.0";
NSString *currSysVer = [[UIDevice currentDevice] systemVersion];
if ([currSysVer compare:reqSysVer options:NSNumericSearch] != NSOrderedAscending)
    useEnumeratedLineParsing = TRUE;

Then check the value of useEnumeratedLineParsing.
