    copied!<p>This should be easy, but I'm having a hard time finding the easiest solution.</p> <p>I need an <code>NSString</code> that is equal to another string concatenated with itself a given number of times.</p> <p>For a better explanation, consider the following python example:</p> <pre><code>&gt;&gt; original = "abc" "abc" &gt;&gt; times = 2 2 &gt;&gt; result = original * times "abcabc" </code></pre> <p>Any hints?</p> <hr> <p>EDIT:</p> <p>I was going to post a solution similar to the one by <a href="https://stackoverflow.com/questions/260945/create-nsstring-by-repeating-another-string-a-given-number-of-times#260969">Mike McMaster's answer</a>, after looking at this implementation from the OmniFrameworks:</p> <pre><code>// returns a string consisting of 'aLenght' spaces + (NSString *)spacesOfLength:(unsigned int)aLength; { static NSMutableString *spaces = nil; static NSLock *spacesLock; static unsigned int spacesLength; if (!spaces) { spaces = [@" " mutableCopy]; spacesLength = [spaces length]; spacesLock = [[NSLock alloc] init]; } if (spacesLength &lt; aLength) { [spacesLock lock]; while (spacesLength &lt; aLength) { [spaces appendString:spaces]; spacesLength += spacesLength; } [spacesLock unlock]; } return [spaces substringToIndex:aLength]; } </code></pre> <p>Code reproduced from the file:</p> <pre><code>Frameworks/OmniFoundation/OpenStepExtensions.subproj/NSString-OFExtensions.m </code></pre> <p>on the OpenExtensions framework from the <a href="http://www.omnigroup.com/developer/" rel="noreferrer">Omni Frameworks</a> by <a href="http://www.omnigroup.com/" rel="noreferrer">The Omni Group</a>.</p>
