    <p>I'm trying to create a custom "blinking cursor" in UIKit, I've tried as shown below, having 2 functions that basically keep calling each other until the cursor is hidden. But this leads to a nice infinite recursion... for some reason the functions call each other right away, not each half-second as expected.</p> <p>I tried returning if the 'finished' parameter is not YES (by uncommenting the 'if (!ok)' line), but that leads to no animation at all...</p> <p>Any better idea? Did I miss something, is there a much-easier way to make a "blinking cursor"?</p> <pre><code>- (void)onBlinkIn:(NSString *)animationID finished:(BOOL)ok context:(void *)ctx { if (cursorView.hidden) return; //if (!ok) return; [UIView beginAnimations:nil context:UIGraphicsGetCurrentContext()]; [UIView setAnimationCurve:UIViewAnimationCurveEaseInOut]; [UIView setAnimationDuration:0.5f]; [UIView setAnimationDelegate:self]; [UIView setAnimationDidStopSelector:@selector(onBlinkOut:finished:context:)]; cursorView.textColor = [UIColor grayColor]; [UIView commitAnimations]; } - (void)onBlinkOut:(NSString *)animationID finished:(BOOL)ok context:(void *)ctx { if (cursorView.hidden) return; [UIView beginAnimations:nil context:UIGraphicsGetCurrentContext()]; [UIView setAnimationCurve:UIViewAnimationCurveEaseInOut]; [UIView setAnimationDuration:0.5f]; [UIView setAnimationDelegate:self]; [UIView setAnimationDidStopSelector:@selector(onBlinkIn:finished:context:)]; cursorView.textColor = [UIColor clearColor]; [UIView commitAnimations]; } </code></pre>

    1. COThe context parameter is a void pointer, not a CGContextRef (although passing a CGContextRef is valid, it certainly won't be useful)

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.
