    <p>The question was asked long ago, but here goes.</p> <p>As said above, textColor for <code>UILabel</code> is not animate-able. A useful trick is to dynamically create in code another <code>UILabel</code>, with the same attributes and position, but with a destination color. You animate the alpha of the new <code>UILabel</code> from 0.0 to 1.0, so it appears like the textColor of the original UILabel is animated. You can remove one of the labels when the animation is completed.</p> <p>Here is an example of a class level method that changes to a different textColor for a short while and changes it back.</p> <pre><code>+(void)colorizeLabelForAWhile:(UILabel *)label withUIColor:(UIColor *)tempColor animated:(BOOL)animated { // We will: // 1) Duplicate the given label as a temporary UILabel with a new color. // 2) Add the temp label to the super view with alpha 0.0 // 3) Animate the alpha to 1.0 // 4) Wait for awhile. // 5) Animate back and remove the temporary label when we are done. // Duplicate the label and add it to the superview UILabel *tempLabel = [[UILabel alloc] init]; tempLabel.textColor = tempColor; tempLabel.font = label.font; tempLabel.alpha = 0; tempLabel.textAlignment = label.textAlignment; tempLabel.text = label.text; [label.superview addSubview:tempLabel]; tempLabel.frame = label.frame; // Reveal the temp label and hide the current label. if (animated) [UIView beginAnimations:nil context:nil]; tempLabel.alpha = 1; label.alpha = 0; if (animated) [UIView commitAnimations]; // Wait for while and change it back. dispatch_after(dispatch_time(DISPATCH_TIME_NOW, FOR_AWHILE_TIME*NSEC_PER_SEC), dispatch_get_main_queue(), ^{ if (animated) { // Change it back animated [UIView animateWithDuration:0.5 animations:^{ // Animate it back. label.alpha = 1; tempLabel.alpha = 0; } completion:^(BOOL finished){ // Remove the tempLabel view when we are done. [tempLabel removeFromSuperview]; }]; } else { // Change it back at once and remove the tempLabel view. label.alpha = 1.0; [tempLabel removeFromSuperview]; } }); } </code></pre>

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.
