Getting NSRange from Subclassed UIPasteboard Selection - iphone

I am wondering if there is some way to subclass UIPasteboard in order to get the selection behavior, but not get the "Cut, Copy, and Paste" options. In addition to this, is there some notification I can subscribe to that returns the NSRange of the selected body of text once it is selected?
Thanks for any help!
EDIT: I would like to use this subclass to allow the user to indicate the area that they would like to run a function on.

There are two notifications supported by UIPasteboard:
UIPasteboardChangedNotification
UIPasteboardRemovedNotification
I've looked through the relevant docs and not seen any way to get a range of the selection.
It's possible that future OS versions might give a little more support in this area.

Is there an existing iOS component to type in a UITextView? [duplicate]

In my app I want the user to type names into a UITextField (or equivalent) and then when they press return, it will put that word(s) in a blue bubble that's usually associated with tags. The cursor then moves to the end where they can add more "tags".
This can be seen when adding contacts in the To, CC & BCC fields in the Mail app, and also when selecting contacts in the Messages app.
How is this done? Is it something that's provided in the UIKit or available somewhere else?
Many thanks,
Michael
Venmo just open sourced their token field.

The equivalent control in desktop Cocoa is an NSTokenField, but there doesn't seem to be an equivalent for Cocoa Touch.
Since iOS 13 there exists UISearchTextField.

You can see that component in action in the Photos App.
That should fit for many use cases. By removing the leftView you can also get rid of the search icon.
But be aware: You can‘t mix text and tokens at various positions.
From the docs:
Tokens always occur contiguously before any text in the search field.
Adding this here for reference:
Feel free to check out TaggerKit (a library I made), it's more or less what OP was talking about. You can basically add tags functionality to your app by just adding a view and a couple of properties.
I dont think you can do it with any built in functionality in the SDK, never seen such a feature. What you could do however is implement it yourself, have some custom blue button with some text over it, and when the user hits return you can have some code that takes the text and returns you the button that you need, shouldnt be too bad to implement

Conditionally color portion of the text of the UITextField

I've a UITextField, I need to color some specific word in a gray
Is there a direct solution?
If not, I think If I got the Source code for setTextColor method, try to conditinoally change its implementation (may be through a Category or even subclassing).
It's not possible as is. To implement that kind of feature you have to use CoreText.
For more info read this great tutorial: http://www.cocoanetics.com/2011/01/befriending-core-text/

Iphone SDK, switch keyboard in app

I have one question, may be it is very simple, but I do not know about this nothing...
For example, I have an application, application with textfield, I want to know two things.
First: Is possible to switch keyboard when application in runtime?
Second: how I can switch type of keyboard(Russian, English, Swedish, etc.) in my application*?
*-without going to Settings->General->Keyboard->add new keyboard.
Not sure about changing languages (I did find this other post about it: change input source language programmatically OSx), but changing the keyboard is pretty easy. Here is a one line example:
textField.keyboardType = UIKeyboardTypeURL;
Take a look at the UITextInputTraits protocol reference for more info. Then the question comes in where to implement this. I am assuming that you want to check conditions right before the keyboard comes up, you may have to implement UITextFieldDelegate protocol (and maybe using the field's tag to see which field the cursor is in).
Hope this helps.

How to Create the Highlight/Note Popup Buttons from the iPhone Kindle

I am wondering how Amazon did the highlight/note popup buttons in the Kindle app. After reading about UIPasteboard, UIMenuController, UIResponder, and UIResponderStandardEditActions, I am able to turn on or off standard edit actions (i.e. copy, cut, paste, select, and selectAll). However I haven't found a way to add a custom action yet. I would really appreciate it if I could get a pointer.
Thanks in advance!

It looks like Amazon implemented their own custom view that mimicked the appearance of UIMenuController. I believe they did this rather than use SPI because if you click and hold on the Highlight cell, the arrow does not highlight, when it does in the real UIMenuController.
I don’t think there is a public interface to these controls, you’d probably have to code them yourself. (Or maybe figure out the private API, but that’s a slippery slope.) I am not sure about that, though, maybe somebody will prove me wrong.
That's a good point about the arrow part of the Notes/Highlight popup menu not highlighting, so they must be implementing their own.
However they are also obviously using a UIWebView, because it's recognizing tap and hold and they can highlight the text, and you can't get touch events from a UIWebView, much less get the information about what's selected. So how are they doing that?
This would be very useful for us to be able to do as well.
Use DTMenuController http://www.drobnik.com/touch/2010/01/dr-touchs-parts-store/
Costs 100 EUR ^_^
Custom menu items can be added via the UIMenuController's menuItems property. See Apple's UIMenuController docs.
the javascript part can be managed with jQuery, that's a fair simple and powerful library. i'm using it for resizing and rearranging things in a webview and it works great :)

Is there an iPhone equivalent to the NSTokenField control?
