    <p>In my project i'm using a UITextField which is embedded into a plain white UIButton with rounded corners in order to create a "beautiful" text field. This code is used several times in different views so I decided to create a custom UIView for this purpose. The code for this custom UIView:</p> <p>BSCustomTextField.h</p> <pre><code>#import &lt;Foundation/Foundation.h&gt; @interface BSCustomTextField : UIView { UIButton* btnTextFieldContainer; UITextField* textField; NSString* text; } @property (retain, nonatomic) UIButton* btnTextFieldContainer; @property (retain, nonatomic) UITextField* textField; @property (retain, nonatomic) NSString* text; -(id)initWithPosition:(CGPoint)position; @end </code></pre> <p>BSCustomTextField.m</p> <pre><code>#import "BSCustomTextField.h" #import &lt;QuartzCore/QuartzCore.h&gt; @implementation BSCustomTextField @synthesize btnTextFieldContainer, textField, text; -(id)initWithPosition:(CGPoint)position{ if (self == [super init]) { btnTextFieldContainer = [[UIButton alloc] initWithFrame:CGRectMake(position.x, position.y, 260, 50)]; btnTextFieldContainer.backgroundColor = [UIColor whiteColor]; [[btnTextFieldContainer layer] setCornerRadius:3.]; [[btnTextFieldContainer layer] setMasksToBounds:YES]; [[btnTextFieldContainer layer] setBorderWidth:0.]; textField = [[UITextField alloc] initWithFrame:CGRectMake(10, 10, 240, 30)]; textField.backgroundColor = [UIColor whiteColor]; textField.clearButtonMode = UITextFieldViewModeAlways; textField.returnKeyType = UIReturnKeySend; textField.keyboardType = UIKeyboardTypeEmailAddress; textField.font = [UIFont fontWithName:@"Helvetica-Bold" size:20.]; [btnTextFieldContainer addSubview:textField]; [self addSubview:btnTextFieldContainer]; } return self; } -(void)dealloc{ [btnTextFieldContainer release]; [textField release]; [super dealloc]; } @end </code></pre> <p>So, when using this view in the <em>viewDidLoad</em> of the container view (see code below) the view is properly rendered on the desired position and looks exactly as specified but it does not react on touch events and thus does not become first responder when touched.</p> <p>Code:</p> <pre><code>searchTextField = [[BSCustomTextField alloc] initWithPosition:CGPointMake(30, 150)]; searchTextField.textField.placeholder = NSLocalizedString(@"lsUserName", @""); [[(BSPlainHeaderWithBackButtonView*)self.view contentView] addSubview:searchTextField]; </code></pre> <p>Calling <em>[searchTextField.textField becomeFirstResponder]</em> programmatically works properly and makes the keyboard to appear.</p> <p>But, the interesting part is, if I embed the code of <em>BSCustomTextField</em> inline in my container just like this:</p> <pre><code>UIButton* btnTextFieldContainer = [[UIButton alloc] initWithFrame:CGRectMake(30, 150, 260, 50)]; btnTextFieldContainer.backgroundColor = [UIColor whiteColor]; [[btnTextFieldContainer layer] setCornerRadius:3.]; [[btnTextFieldContainer layer] setMasksToBounds:YES]; [[btnTextFieldContainer layer] setBorderWidth:0.]; searchTextField = [[UITextField alloc] initWithFrame:CGRectMake(10, 10, 240, 30)]; searchTextField.backgroundColor = [UIColor whiteColor]; searchTextField.clearButtonMode = UITextFieldViewModeAlways; searchTextField.returnKeyType = UIReturnKeySend; searchTextField.keyboardType = UIKeyboardTypeEmailAddress; searchTextField.font = [UIFont fontWithName:@"Helvetica-Bold" size:20.]; searchTextField.placeholder = NSLocalizedString(@"lsUserName", @""); [btnTextFieldContainer addSubview:searchTextField]; [[(BSPlainHeaderWithBackButtonView*)self.view contentView] addSubview:btnTextFieldContainer]; [btnTextFieldContainer release]; </code></pre> <p>everything works as expected and the textfield reacts on touches. The type of the searchTextField is properly set in the header file for each case. The only difference is that in the first case I have an additional wrapping UIView on the UIButton and the UITextFiled. I have no idea what to do to make the text field to become first responder on touch.</p> <p>Thanks a lot in advance, Roman</p>

    2. COSorry, I don't clearly understand what exactly do you mean. "0." is a float value and has exactly the effect which I expect - it sets the border of the UIButton layer to zero.

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).
