Using the textfield delegate, there’s a method – (BOOL)textField:(UITextField *)textField shouldChangeCharactersInRange:(NSRange)range replacementString:(NSString *)string Return NO from this, and any attempt by the user to edit the text will be rejected. That way you can leave the field enabled but still prevent people pasting text into it.
You could also mask the component. With a bit fiddeling you can get the size of the component and cut it out with following code: CALayer* mask = [[CALayer alloc] init]; [mask setBackgroundColor: [UIColor blackColor].CGColor]; [mask setFrame: CGRectMake(10.0f, 10.0f, 260.0f, 196.0f)]; [mask setCornerRadius: 5.0f]; [picker.layer setMask: mask]; [mask release]; Don’t forget #import <QuartzCore/QuartzCore.h>
Create your picker, create a label with a shadow, and push it to a picker’s subview below the selectionIndicator view. It would look something like this UILabel *label = [[[UILabel alloc] initWithFrame:CGRectMake(135, 93, 80, 30)] autorelease]; label.text = @”Label”; label.font = [UIFont boldSystemFontOfSize:20]; label.backgroundColor = [UIColor clearColor]; label.shadowColor = [UIColor whiteColor]; label.shadowOffset = CGSizeMake (0,1); … Read more
Here is a solution to get the same effect. For using this snippet of code you should replace UIPickerView to CDatePickerViewEx in nib file in “Custom class” of “Indentity inspector”. .h file #import <UIKit/UIKit.h> @interface CDatePickerViewEx : UIPickerView <UIPickerViewDelegate, UIPickerViewDataSource> @property (nonatomic, strong, readonly) NSDate *date; -(void)selectToday; @end .m file #import “CDatePickerViewEx.h” // Identifiers of … Read more
It’s just as easy to set the number of rows to a large number, and make it start at a high value, there’s little chance that the user will ever scroll the wheel for a very long time — And even then, the worse that will happen is that they’ll hit the bottom. – (NSInteger)pickerView:(UIPickerView … Read more
It seems obvious that Apple doesn’t particularly invite mucking with the default height of the UIPickerView, but I have found that you can achieve a change in the height of the view by taking complete control and passing a desired frame size at creation time, e.g: smallerPicker = [[UIPickerView alloc] initWithFrame:CGRectMake(0.0, 0.0, 320.0, 120.0)]; You … Read more
One more solution: no toolbar but a segmented control (eyecandy) UIActionSheet *actionSheet = [[UIActionSheet alloc] initWithTitle:nil delegate:nil cancelButtonTitle:nil destructiveButtonTitle:nil otherButtonTitles:nil]; [actionSheet setActionSheetStyle:UIActionSheetStyleBlackTranslucent]; CGRect pickerFrame = CGRectMake(0, 40, 0, 0); UIPickerView *pickerView = [[UIPickerView alloc] initWithFrame:pickerFrame]; pickerView.showsSelectionIndicator = YES; pickerView.dataSource = self; pickerView.delegate = self; [actionSheet addSubview:pickerView]; [pickerView release]; UISegmentedControl *closeButton = [[UISegmentedControl alloc] initWithItems:[NSArray arrayWithObject:@”Close”]]; … Read more
You get the fonts using this loop: NSMutableArray *fontNames = [NSMutableArray array]; for(NSString *familyName in [UIFont familyNames]) { for(NSString *fontName in [UIFont fontNamesForFamilyName:familyName]) { [fontNames addObject:fontName]; } } How you present the picker depends on your UI layout. You might use an UITableView in an UIPopoverController (just google it, you’ll find TONS of quite good … Read more
You can set a pickerView as the textField.inputView. The example below is for two text fields sharing a single picker view, but you can extend it easily by checking the identity of the activeTextField in the picker view delegate methods. import UIKit class ViewController: UIViewController, UIPickerViewDelegate, UIPickerViewDataSource { @IBOutlet weak var myTextFieldOne: UITextField! @IBOutlet weak … Read more
