    <p>I have a subclass of <code>UITableView</code> and in it I want to generate number of labels that share the same properties (font, textColor, backgroundColor, etc.).</p> <p>I decided the easiest way to achieve this would be to create a helper method which creates the label with some common properties set:</p> <pre><code>- (UILabel *)defaultLabelWithFrame:(CGRect)frame { UILabel *label = [[UILabel alloc] initWithFrame:frame]; label.font = [UIFont fontWithName:@"Helvetica" size:14]; label.textColor = [UIColor colorWithWhite:128.0/255.0 alpha:1.0]; label.backgroundColor = [UIColor clearColor]; return label; } </code></pre> <p>I use the method like this:</p> <pre><code>UILabel *someLabel = [self defaultLabelWithFrame:CGRectMake(0,0,100,100)]; [self addSubview:someLabel]; [someLabel release]; </code></pre> <p>My concern here is that <strong>when creating the label in the method it is retained, but when I then assign it to someLabel, it is retained again and I have no way of releasing the memory when created in the method</strong>.</p> <p><strong>What would be best the best approach here?</strong></p> <p>I fee like I have two options:</p> <ol> <li> Create a subclass of UILabel for the default label type. </li> <li> Create an NSMutableArray called <b>defaultLabels</b> and store the labels in this: </li></ol> <pre><code>- (UILabel *)defaultLabelWithFrame:(CGRect)frame { UILabel *label = [[UILabel alloc] initWithFrame:frame]; label.font = [UIFont fontWithName:@"Helvetica" size:14]; label.textColor = [UIColor colorWithWhite:128.0/255.0 alpha:1.0]; label.backgroundColor = [UIColor clearColor]; [defaultLabels addObject:label]; [labels release]; //I can release here return [defaultLabels lastObject]; //I can release defaultLabels when done } </code></pre> <p>I appreciate your thoughts. Cheers.</p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
