POHow do you load custom UITableViewCells from Xib files?
text
Body
copied!<p>The question is simple: How do you load custom <code>UITableViewCell</code> from Xib files? Doing so allows you to use Interface Builder to design your cells. The answer apparently is not simple due to memory managment issues. <a href="https://stackoverflow.com/questions/134575/using-interface-builder-for-uitableviews">This thread</a> mentions the issue and suggests a solution, but is pre NDA-release and lacks code. Here's a <a href="http://discussions.apple.com/thread.jspa?messageID=8040526&tstart=0" rel="nofollow noreferrer">long thread</a> that discusses the issue without providing a definitive answer. </p> <p>Here's some code I've used:</p> <pre><code>static NSString *CellIdentifier = @"MyCellIdentifier"; MyCell *cell = (MyCell *)[tableView dequeueReusableCellWithIdentifier:CellIdentifier]; if (cell == nil) { NSArray *nib = [[NSBundle mainBundle] loadNibNamed:CellIdentifier owner:self options:nil]; cell = (MyCell *)[nib objectAtIndex:0]; } </code></pre> <p>To use this code, create MyCell.m/.h, a new subclass of <code>UITableViewCell</code> and add <code>IBOutlets</code> for the components you want. Then create a new "Empty XIB" file. Open the Xib file in IB, add a <code>UITableViewCell</code> object, set its identifier to "MyCellIdentifier", and set its class to MyCell and add your components. Finally, connect the <code>IBOutlets</code> to the components. Note that we did not set the File's Owner in IB.</p> <p>Other methods advocate setting the File's Owner and warn of memory leaks if the Xib is not loaded via an additional factory class. I tested the above under Instruments/Leaks and saw no memory leaks. </p> <p>So what's the canonical way to load cells from Xibs? Do we set File's Owner? Do we need a factory? If so, what's the code for the factory look like? If there are multiple solutions, let's clarify the pros and cons of each of them...</p>
