    <p>I am using the MHRotaryKnob Class and having trouble configuring it so that multiple outlets have the same default settings. It is no problem to get it working with one instance using IBOutlet, but now it is looking for the properties of the MHRotaryKnob class in NSArray.</p> <p>How exactly do I define rotaryKnob in the implementation so that the settings are relayed to all controls hooked up to IBOutletCollection? The properties in the implementation are defined in MHRotaryKnob.m but now the compiler is looking for it in NSArray. </p> <h2>ViewController.h</h2> <pre><code>#import &lt;UIKit/UIKit.h&gt; #import "MHRotaryKnob.h" @interface CBViewController : UIViewController @property (nonatomic, retain) IBOutletCollection (MHRotaryKnob) NSArray *rotaryKnob; </code></pre> <h2>ViewController.m</h2> <pre><code>#import "ViewController.h" #import "MHRotaryKnob.h" @implementation CBViewController; @synthesize rotaryKnob; - (void)viewDidLoad { [super viewDidLoad]; rotaryKnob.interactionStyle = MHRotaryKnobInteractionStyleSliderVertical; rotaryKnob.scalingFactor = 1.5f; rotaryKnob.defaultValue = rotaryKnob.value; rotaryKnob.resetsToDefault = YES; rotaryKnob.backgroundColor = [UIColor whiteColor]; rotaryKnob.backgroundImage = [UIImage imageNamed:@"knob_passive.png"]; [rotaryKnob setKnobImage:[UIImage imageNamed:@"knob_passive.png"] forState:UIControlStateNormal]; [rotaryKnob setKnobImage:[UIImage imageNamed:@"knob_highlighted.png"] forState:UIControlStateHighlighted]; [rotaryKnob setKnobImage:[UIImage imageNamed:@"Knob Disabled.png"] forState:UIControlStateDisabled]; rotaryKnob.knobImageCenter = CGPointMake(35.0f, 32.0f); [rotaryKnob addTarget:self action:@selector(rotaryKnobDidChange) forControlEvents:UIControlEventValueChanged]; </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.
