iPhone app. Creating a custom UIView that contains UITextField and UIButton.
- by Dmitry Burchik
Hi all. I am new to iPhone programming. And I have an issue. I need to create a custom user control that I will add to my UIScrollView dinamically. The control has an UITextField and an UIButton. See the code below:
#import <UIKit/UIKit.h>
@interface FieldWithValueControl : UIView {
UITextField *txtTagName;
UIButton *addButton;
}
@property (nonatomic, readonly) UITextField *txtTagName;
@property (nonatomic, readonly) UIButton *addButton;
@end
#import "FieldWithValueControl.h"
#define ITEM_SPACING 10
#define ITEM_HEIGHT 20
#define SWITCHBOX_WIDTH 100
#define SCREEN_WIDTH 320
#define ITEM_FONT_SIZE 14
#define TEXTBOX_WIDTH 150
@implementation FieldWithValueControl
@synthesize txtTagName;
@synthesize addButton;
- (id)initWithFrame:(CGRect)frame {
if (self = [super initWithFrame:frame]) {
// Initialization code
txtTagName = [[UITextField alloc] initWithFrame:CGRectMake(0, 0, TEXTBOX_WIDTH, ITEM_HEIGHT)];
txtTagName.borderStyle = UITextBorderStyleRoundedRect;
addButton = [UIButton buttonWithType:UIButtonTypeContactAdd];
[addButton setFrame:CGRectMake(ITEM_SPACING + TEXTBOX_WIDTH, 0, ITEM_HEIGHT, ITEM_HEIGHT)];
[addButton addTarget:self action:@selector(addButtonTouched:)
forControlEvents:UIControlEventTouchUpInside];
[self addSubview:txtTagName];
[self addSubview:addButton];
}
return self;
}
- (void)addButtonTouched:sender
{
UIButton *button = (UIButton*)sender;
NSString *title = [button titleLabel].text;
}
- (void)drawRect:(CGRect)rect {
// Drawing code
}
- (void)dealloc {
[txtTagName release];
[addButton release];
[super dealloc];
}
@end
In my code I create an object of that class and add it to scrollView on form.
FieldWithValueControl *newTagControl = (FieldWithValueControl*)[[FieldWithValueControl alloc] initWithFrame:CGRectMake(ITEM_SPACING, currentOffset + ITEM_SPACING, 0, 0)];
[scrollView addSubview:newTagControl];
The control looks fine, but if I click to the textbox or to the button nothing happens. Keyboard doesn't appear, the button is not clickable etc.
