    <p>I'm trying to structure some view-code out of the controller (obviously without using a nib). Therefore, I tried a simple example, but for some reason, I can't add the target to the button in the controller, rest is fine. Here's what I'm trying:</p> <p>Controller.h:</p> <pre><code>#import &lt;UIKit/UIKit.h&gt; #import "IndexView.h" @interface IndexController : UIViewController { } @property (nonatomic) IndexView *contentView; @end </code></pre> <p>Controller.m</p> <pre><code>#import "IndexController.h" #import "IndexView.h" @interface IndexController () @end @implementation IndexController - (id)initWithNibName:(NSString *)nibNameOrNil bundle:(NSBundle *)nibBundleOrNil { self = [super initWithNibName:nibNameOrNil bundle:nibBundleOrNil]; if (self) { self.contentView = [[IndexView alloc]init]; [self.view addSubview:self.contentView]; [self connectUIElements]; } return self; } - (void) connectUIElements { [self.contentView.testButton addTarget:self action:@selector(testButtonClicked) forControlEvents:UIControlEventTouchUpInside]; } #pragma mark -- #pragma mark UIHandler - (void) testButtonClicked { NSLog(@"testbutton clicked"); } @end </code></pre> <p>View.h</p> <pre><code>#import &lt;UIKit/UIKit.h&gt; @interface IndexView : UIView @property (nonatomic, strong) UIButton *testButton; @end </code></pre> <p>View.m</p> <pre><code>#import "IndexView.h" @implementation IndexView - (id)initWithFrame:(CGRect)frame { self = [super initWithFrame:frame]; if (self) { [self setUpView]; } return self; } - (id) init { self = [super init]; if (self) { [self setUpView]; } return self; } - (void) setUpView { [self setBackgroundColor:[UIColor whiteColor]]; self.testButton = [[UIButton alloc]initWithFrame:CGRectMake(10, 50, 100, 50)]; self.testButton.backgroundColor = [UIColor greenColor]; [self.testButton setTitle:@"hello, world" forState:UIControlStateNormal]; [self addSubview:self.testButton]; } @end </code></pre> <p>I'm just exploring possibilities to get closer to a classical MVC pattern and a little farther away from Apples mediator-interpretation. Any idea what's wrong?</p>

    1. COHave you tried making your `IndexView` outlet `strong`?

    3. COYou init the view with `[[IndexView alloc]init]`, so I wonder if `initWithFrame` and `setUpView` of `IndexView` is called at all ...

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.

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