    <p>I have tried many methods to implement a regular <code>UISlider</code> and control the device volume, but it's all Native-C functions which results in many untraceable bugs. </p> <p>I tried the <code>MPVolumeView</code> it works like charm, it even controls the device volume even after you close the app, just like the iPod app.</p> <p>My question is, is there anyway to customize the <code>MPVolumeView</code> with specific colors and images, just like <code>UISlider</code>?</p> <p>NOTE: I want a legal method without using private undocumented APIs.</p> <p><strong>UPDATE</strong><br> As per @Alexsander Akers answer, since the sub views are hidden in <code>MPVolumeView</code> I had to cycle through subviews, get the <code>UISlider</code> and customize it, here is the code.</p> <pre><code>IBOutlet UISlider *volumeSlider; //defined in &lt;class.h&gt; and connected to a UISlider in Interface Builder -(void) viewDidLoad { .... [self setCustomSlider]; .... } -(void) setCustomSlider{ MPVolumeView *volumeView = [[[MPVolumeView alloc] initWithFrame:[volumeSlider frame]] autorelease]; NSArray *tempArray = volumeView.subviews; for (id current in tempArray){ if ([current isKindOfClass:[UISlider class]]){ UISlider *tempSlider = (UISlider *) current; UIImage *img = [UIImage imageNamed:@"trackImage.png"]; img = [img stretchableImageWithLeftCapWidth:5.0 topCapHeight:0]; [tempSlider setMinimumTrackImage:img forState:UIControlStateNormal]; [tempSlider setThumbImage:[UIImage imageNamed:@"thumbImage.png"] forState:UIControlStateNormal]; } } [volumeSlider removeFromSuperview]; [self.view addSubview:volumeView]; } </code></pre>

    3. CO@sooper very late reply, sorry. Unfortunately, I didn't continue this app and never submitted it to App Store. But from personal experience, I have seen many tutorials of modifying the original components and they were accepted.

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.

SQuiL has stopped working due to an internal error.

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