Find value in Array in objective C

Question

I have a NSArray structure likes this {w123,123,234,345,w124,234,235,w125,234,453,435,....}

What I am trying to do is to specify which one begins with "w" then do something But I don't know how to do that in objective C, anyone can help? Thanks in advance.

Answer 1

for (NSString *text in myArray) {
    if ([text hasPrefix:@"w"]) {
       // Do something.
    }
}
