Extracting string based object from array

Question

I have any NSarray of NSString objects.

I want to extract those string which only contains character or character&numeric from it.

For example: "D6,Bombay.Hello”" is valid whereas “123456.123,56” is invalid.

Please help if anyone have idea.

@AntonyRaphel-here is an array ( 1.1, Detais of members, holder, more than 5% of total, d up capital, Name of the Share Holders, Mr John, ABC Limited, No. of Share, 2,34,105 74.50, 14,440 04.60, 28.940, 09.21, 2013-14, 234,105 74.50, 14,440 04.60, 28940 09.21, ) — nik, Feb 03 '17 at 09:05

You can filter array using predicate to get only

NSPredicate *pred = [NSPredicate predicateWithBlock:^BOOL(id str, NSDictionary *unused) {
    return ([str rangeOfCharacterFromSet:[NSCharacterSet letterCharacterSet]].location != NSNotFound);
}];

NSArray *filtered = [yourArray filteredArrayUsingPredicate:pred];
