Is there any code for highlighting the button in backgroungview? If I Press the button it should be highlighted and also popupview should appear in the same screen.Like this image
While clicking , you just add the another button to UIWindow.... So u get the popup like appearance of button..
I'm trying to get special behavior of UISearchBar. I want never to show "Cancel" button (this part i'm already implement) and show Bookmarks button always.
But if i hide cancel button, bookmarks button is hide too in editing mode (only if searchBar.text.length > 0)
How i hide cancel button:
UITextField *textField = [searchBar valueForKey:#"_searchField"];
textField.clearButtonMode = UITextFieldViewModeNever;
Picks:
My question is how can i always show only bookmarks button?
You also need to set this:
textField.rightViewMode = UITextFieldViewModeAlways;
I want to have a function that by pressing the 1st button, then the 2nd button will be appear. When the 2nd button appear, after pressing it, then the 3rd button will appear and so on until the 10th button.
Making IBAction for each button can do the job. But it will be very time consuming. And I have multiple of these sequence needed to be done.
Is there any other way is faster and simpler to get this job done?
Thanks
For this purpose, you have to use the tag property of UIButton. while creating the UIButton set the tag value. For example for button1 it should be 1, for button2 it should be 2, and so on...
After that set the same IBAction for all UIButtons. And inside that IBAction get the button based on tag value and unhide next UIButton.
-(IBAction)buttonClicked:(id)sender
{
UIButton *button = (UIButton *)[self.view viewWithTag:(sender.tag + 1)];
button.hidden = NO;
}
You should be use loop for these process . . .
(if second button not appear only on first button click)
i want to write the text to UILabel which is inputed from iphone's keypad. when i tapped button as in screen shot. how i can do that ? i don't want to use Textfield.
-(IBAction) buttonTapped {
[self.yourlabel setText:[textField text]];
}
Add a UITextField (you can name it hiddenTextField) some where, and set it hidden in view, so it'll become invisible to everyone, in viewDidLoad method of that UIViewController write,
[hiddenTextField becomeFirstResponder]; //it will make UIKeyBoard show on screen
On your UIButton action write,
- (IBAction)myAction {
myLabel.text = hiddenTextField.text;
//Don't forget to set `hiddenTextField` delegate to self.
[hiddenTextField resignFirstResponder];
}
How can I bring up the iphone keyboard by clicking a button - I haven't created any text fields. My intention is to have labels that hold a single character.
Other people have asked this and it has been answered but it was from years ago and I didn't understand what people meant in there responses.
Thank you for any help in advance.
Only way you could do this is via hidden UITextField, and set that textField to becomeFirstResponder
you could hide the text field in your code liket his textfield.hidden=YES;
or you could hide the textfield from nib file also by going into the attribute inspector and tick the Hidden property
You could have a look at this UIKeyInput- Displaying keyboard in iPhone without UITextField or UITextView, I have not tried myself this
Attach the button to a touchUpInside event and call becomeFirstResponder on the textView or textfield:
Here is an example (to bring it up when a text view is clicked):
-(IBAction)buttonClicked:(id)sender{
[textView becomeFirstResponder];
}
-(void)ButtonClicked
{
[textFld becomeFirstResponder];
[textView becomeFirstResponder];
}
use this method
You can add a hidden UITextFeild as tempTF and when the button clicked. call becomeFirstResponder of this textFeild:
[self.tempTF becomeFirstResponder];
To Hide textField:
UITextField *tempTF = [[UITextField alloc] init];
tempTF.hidden = YES
or mark Hidden ir your Interface Builder
