    <p>It's hard for me to describe the problem, and I'll use screenshots. They are all from my simulator, when I test in my <code>iPodTouch4</code>, its the same. I have several <code>UILabel</code> s, which are rects in the picture.</p> <p><img src="https://i.stack.imgur.com/kxKjt.jpg" alt="1.Retina display, UILabels"></p> <p>Notice there are black lines on the right of some rects, which is unexpected, because I didn't code any extra behavior except for backgoundColor and frame.</p> <p>When I change <code>UILabel</code> to <code>UIView</code> (nothing else changed), every thing becomes normal! <img src="https://i.stack.imgur.com/bsi7U.jpg" alt="Retina display, UIViews"></p> <p>And when use <code>UILabel</code> not in retina display, we can see clearly than some rects have different width, but according to my code and the log, they have same width! Realllllly Weird! <img src="https://i.stack.imgur.com/FVwA9.jpg" alt="no retina display UILabel"> </p> <p>I can't figure out why. It might be something special about <code>UILabel</code>, but I can't find anywhere int the documentation.</p> <p>[this is how I create labels]</p> <pre><code>NSMutableArray *labels = [NSMutableArray array]; for (NSString *day in [self getDaysOfTheWeek]) { UILabel *dayOfWeekLabel = [[UILabel alloc] initWithFrame:CGRectZero]; [labels addObject:dayOfWeekLabel]; } self.dayOfWeekLabels = labels; </code></pre> <p>[this is where I set their frames]</p> <pre><code>int count = 0; for (UILabel *dayLabel in self.dayOfWeekLabels) { dayLabel.frame = CGRectMake(CELL_BORDER_WIDTH + count*(self.cellWidth+CELL_BORDER_WIDTH), CELL_BORDER_WIDTH, self.cellWidth, self.daysHeader.frame.size.height); dayLabel.backgroundColor = self.dateBackgroundColor; count++; } </code></pre> <p>Just as I mentioned above, simply change these UILabel to UIView in these code make them looks differently.</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.
