UIReturnKeyDone return or other feedback? - objective-c

So I'm using textfield.returnKeyTYpe = UIReturnKeyDone in my code with my UIKeyboard. The problem that I am running into is that the done button and the hide keyboard button are both performing the same function in that, once they are clicked the keyboard hides but the program continues on to the next field and the keyboard pops up right away.
I want to know if there is something that the UIReturnKeyDone returns when clicked that I can grab to differentiate between clicking the Done key and the hide keyboard key.
Sorry if that does't make sense, I am new to all this.

It now make sense, You need to create UIButton and press it to hide keyboard.
When you want to hide keyboard.
[textView resignFirstResponder];

UITextField: when "Done" is shown in the keyboard?

I have working on implementing sign up screen, and there are three input fields and custom gender selection buttons below them. Now when first field becomes first responder then "Next" button is shown in the right bottom keyboard. Pressing "Next" moves to the second field, and the pressing it again moves to the third field and shows "Done".
I need to override and show "Next" instead "Done", so that a user could press it, I would close keyboard and scroll the screen a little bit so he would see he needs to select gender. Just trying to figure out what causes to show "Done" on last textField.
Try this one :
[textField setReturnKeyType:UIReturnKeyDone];

Issue with UIAlertView buttons

In my app, I've allocated a new UIAlertView...A keyboard pops up in conjunction with its appearance and I can enter whatever I like into the UIAlertView's textfield.
I'm having a problem where, when I type on the keyboard, the color of the button located at index one on the UIAlertView changes every time I strike a key.
I've tried looking at all the right, obvious places...But cannot solve this.
I know a callback is triggered when I hit a key...But yeah.
Please help.
thanks

Block ui when keyboard is up

I've seen a couple of apps that show a transparent view on top of the current ui while the keyboard is present and if clicked it hides the keyboard. I looked around the web and couldnt find a solution for this problem.
Simply add a UIButton, custom type, the size of your screen and add it to your view when your text field (or other entry) takes focus. Make sure your edit view is brought to the front of its superview at the point you add the button (to ensure the edit view still responds to touch).
Add a target to the button which dismisses the keyboard ([myTextfield resignFirstResponder]) and removes the button.
Also make sure to remove the button when the textField dismisses normally.

Is there a way to control the NSMenuItem item that is initially highlighted when opening a menu?

I'm working on the details of a symbols pop up button, similar to what Xcode 3 at the top of its editor window.
My controller object is the delegate of the NSMenu that is shown when the NSPopUpButton is shown. I implement the two methods numberOfItemsInMenu: and menu:updateItem:atIndex:shouldCancel: to populate the menu right before it's about to be displayed.
However, the title and image of the selected NSMenuItem have to change each time the user changes the selection in the editor NSTextView, or makes changes to the text; just as is the case with Xcode.
The problem I'm having is when the user goes to click on the NSPopUpButton to display the NSMenu, the selected NSMenuItem and the item that should be selected do not match up, since the menu doesn't have the proper number of items yet.
I'm wondering if there is a way to control which NSMenuItem is initially highlighted and tracked when the user clicks to open the menu. As it stands, the first item it always highlighted and tracked or, if the user had previously selected a item, that item is highlighted and tracked.
I tried explaining as best I could, but here is a image illustrating my problem:
I want the highlighted item to be the same as the selected item when the user opens the menu. Any ideas?
I would use a NSPopupbutton - it can do what you want. maybe you even hide it?
I am not very sure that I understood your problem but If we can add tags to these menu Items.
e.g.
[mMenuItemOne setTag : 1];
[mMenuItemTwo setTag : 2];
[mMenuItemThree setTag : 3];
[mMenuItemFour setTag : 4];}
we can select any Menu item using
[_popUp selectItemWithTag: _selectedItem];
Just a hint not a full solution.
Try to post an NSMouseMoved event to your app right after the menu shown.
Main problem is here to detect the position of the item you want to be highlighted.
Just a starting point.
Have you tried this NSMenuDelegate method:Handling Highlighting
– menu:willHighlightItem:
NSMenuDelegate Protocol Reference
Also you can store the NSMenuItem index in some var to keep track of the selected item for later use.
I'm not sure, do you want to move the mouse selection highlight (the blue stuff) or the checkmark?
In general, the checkmark is the thing you want to change. You can do so from your validateMenuItem: method (or at any other time if your item is set not to take part in validation) using the -setState: method.
The blue highlight is an indicator of the user's keyboard input or mouse location, and you should not mess with it. Changing it does not make any sense, as it would be changed back the moment the user moves the mouse even a single pixel.
That said, you can set the selectedItem of the NSPopUpButton, which will cause the entire menu to be moved so the selectedItem is under the mouse (assuming the mouse just clicked the popup button).
If your menu delegate method is called after the pop up button has decided what item to select, you can't use it. Instead, you could probably set the selectedItem and menu of the popup button from a NSPopUpButtonWillPopUpNotification handler.
If that is also called too late, you'll probably have to subclass NSPopupButtonCell and do it in an override of -attachPopUpWithFrame:inView: (I think that's the spot that should also work when you don't click and just hit the space key while the popup button is selected).

textfield enable clear button but dont allow the keyboard to come up

Is there a way to have a UITextField with the text read only but still let the clear button work? I have a set of buttons on my view that interact with the text field so i dont need the keyboard to pop but if i disable the text field. the clear button shows up but i cant press it anymore. Is there a way to do this or should i make my own clear button?
Set clearButtonMode to UITextFieldViewModeAlways, and have the delegate return NO for textFieldShouldBeginEditing:.
