I want to keep the place holder text shown while it is focused (that is, while it is the first responder). It should stay that way only until something is typed and the field no longer blank.
Address Book app's Search bar behaves like this, as do the new contact entry fields.
Is there any way to do that?
I don't think this comes "built in" for you to activate it, but you can build it rather easily on your own: Create a UILabel you want to display and when the focus is set onto the TextField place the UILabel at the right spot (slightly after the cursor).
As soon as the user enters a character you hide the UILabel. You can see when the user starts the edit and starts to type by adding your class as delegate to the UISearchBar (see callbacks "searchBar:textDidChange:" and "searchBarTextDidBeginEditing:"): http://bit.ly/eQlvRz

The Text Fields that Say 100 are the ones i'm referring to.
I have Text Fields that I don't want to be editable until a later point so I turned off User Interaction. However, I still want them to function as a button to go to another view. Is there anyway to turn off text input but still keep it as a button?
I am working on an app that uses voice commands to maneuver through text fields. What I need to do is translate the voice command into a touch event on the keyboard. Specifically I need to access the tab key and the return key. The user will not be using the keyboard in this app. I am having a difficult time finding a way to get this done. I know how to convert the voice commands into something that I can use, but I still need to apply that to the keyboard commands. I have researched this extensively and I get what I think are bits and pieces of what I really need, but nothing is connecting the dots for me.
You don't need the keyboard to navigate text fields. You just need to modify the first responder. There unfortunately isn't an easy way to get the current first responder, but you can search for it.
Once you have the first responder, you can move to the next field like this:
[[field nextResponder] becomeFirstResponder];
If you are trying to do this in a very general way, you should first call canBecomeFirstResponder and handle situations where there there are no available first responders and other corner cases, but this generally isn't needed for very simple interfaces.
If you want to manage "enter" in order to end editing and dismiss the keyboard, you can call endEditing: on the superview.
You can modify text without the keyboard by replacing the text property.
I want to create a 4 character custom password entry like the iPhone lock screen page. It's going to have a custom designed keyboard pinpad, but thats not the question. I have 4 boxes for the entry of the pin, and each box is separated and has its own custom design. I currently have a clear UITextView on top of each box. However, I'm not really sure how to link all these together so that when I enter a number in the first box, it automatically advances to the next box so I can type the next number. After the last number has been entered, it should automatically check to see if the password is correct and if so do some action. What is the best way to do this?
When implementing UITextFieldDelegate you should check on textField:shouldChangeCharactersInRange:replacementString:
and you can move keyboard focus to next UITextField via BecomeFirstResponder documentation
So on last UITextField you will hide keyboard and disable all UITextboxes automatically, but If I were you, I would prefer to provide button to start checking pin (to let user correct pin if mistyped)
I have a part on my app that I show the users, the files they have created and have stored inside the app's directory. I want to allow the users to rename the files.
I am wondering of doing this:
The user selects a file
The user taps on the RENAME button.
An alertview pops showing the old name and having a textview where the user can type the new name.
My question is: is this blessed by Apple? This sounds like a hack to the alertview.
Will the app be approved?
I googled around and I saw mixed opinions about that.
thanks
Generally I think the correct HIG-happy UI would be a UITableView with the list of of files. The user taps and Edit button and the page rows become editable, allowing you to delete a row/file (with a verification alert) and a disclosure arrow that pushes a detail view where you can change the name.
An alternative, though not HIG-friendly, is displaying the file name in a UITextField where the borderStyle set to UITextBorderStyleNone and the enabled set to NO. When the user taps the Rename button you change the borderStyle to UITextBorderStyleRoundedRect and enabled set to YES, setting the firstResponder to the text field so the cursor is flashing inside the textField. You'd need OK and Cancel buttons.
Or you could add a text field to the UIAlertView, also against the HIG but perhaps better.
I don't know if the property alertViewStyle was available when you make this question but searching to resolve this problem for me, I found that setting this property with UIAlertViewStylePlainTextInput resolve your problem.
Yes it is in iPhone sdk alertBox, alertBox can have the textField in which you rename the file.
check this link
for making such kind of stuff. No problem in accepting your app
You could either subclass UIAletView and add your own initWithTitle:message:...etc. method, as outlined in this tutorial, or use the undocumented [alert addTextFieldWithValue:#"" label:nil]; method, which is easier but may cause Apple to reject your app.
I am having very annoying issue. I have one form page with 5 custom cells. Each of them has one text field. On the bottom I have one button. In an onclick button function I am gathering values from each of the 5 described text fields.
My problem is that if my keyboard is up, I will get the values of not all but just visible text fields, the ones I don't see are null.
How to override this?
Thx,
Mladen
Separate data you have from your interface, that is store your textfield values in some other place right after you finish input. And access your data there.
UI elements are not intended to store data, but just to display it and allow input - as you can see in your case if you do not see a particular element you cannot be sure that it actually exists.
This might solve your problem..
1. Register your viewcontroller for KeboardNotifications
2.When keyboard will appear resize the view so that all fields will be visible.
3. When keboard will disappear just resize it back and continue..
