Question

I have a String which consists of multiple lines. ex:

line1 A B C

line2 X Y Z

line3 D E F

How can I search for Y in that string and get the whole line? So I would like to get the output as line2 X Y Z

Answer 1

One way is to break the string up into lines first:

NSArray *lines = [myString componentsSeparatedByString:@"\n"];

And then search through the lines:

for (NSString *line in lines) {
    NSRange *range = [line rangeOfString:@"Y"];
    if (range.length > 0) {
        // do something
    }
}
