    <p>i am using <a href="https://github.com/Zedenem/UICircularProgressView" rel="nofollow">UICircularProgressView</a> and have changed it to my liking. the initialization is clear but i'll post it anyways:</p> <pre><code>UICircularProgressView *wheelProgress = [[UICircularProgressView alloc]initWithFrame:CGRectMake(someFrame)]; </code></pre> <p>then i am setting the right progress <code>CGFloat between 0-1</code></p> <pre><code>CGFloat progress = .3; // example [self.wheelProgress setProgress:progress]; </code></pre> <p>This works just fine, and looks good, but i would really like to somehow animate it. I havent worked with animations so far, so my first approach was something like</p> <pre><code>for(tempProgress =! progress){ incrementing tempProgress setting tempProgres to progressView } </code></pre> <p>this of course is massively ugly and blocks everything else going on.</p> <p>what i would like to achieve is a linear animation of the progress from 0 to its final value.</p> <p>i have looked at: <a href="http://www.friendlydeveloper.com/2011/02/basic-ui-animation/" rel="nofollow">Animation tutorial</a></p> <p>and came up with something like this:</p> <pre><code>CGContextRef context = UIGraphicsGetCurrentContext(); [UIView beginAnimations:nil context:context]; [UIView setAnimationCurve:UIViewAnimationCurveLinear]; [UIView setAnimationDuration: 1]; wheelProgress.progress = (progress) ? progress : 0.0; [UIView commitAnimations]; </code></pre> <p>but somehow this does not work..</p> <p>any ideas what i need to fix here?</p> <p>thanks in advance sebastian</p>

    1. COjust use your increment value be very small in order of 0.01f or less so you get what you want

    2. COif i do that the whole application gets blocked for the duration of the animation because i'd have to do it in the main thread that blocks the interface when busy.. im looking for a more elegant solution..

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.
