I've been playing around a little with the UNNotificationContentExtension framework to display a custom view inside a notification. So far, so good - got it rendering, and then altering content when a user taps on an action button.
But the one thing I don't seem to be able to do is change the text in the action buttons - not necessarily surprising given that it is defined in a UNNotificationAction I have to declare beforehand, but I'm wondering if anyone has had any luck in finding a way to change the button text?

I am making app like sudoku (9*9 boxes) but it has only binary choices (on/off) and using button gave me horrible results. Can anyone give me demo version of 9*9 (or 3*3) box where depending upon the tap location, that specific box gets toggled (on/off)
You could create a custom subclass of UIView that had an attached tap gesture recognizer and interpreted the tap location to figure out which cell is being tapped, but it would be a lot of work.
It would be better to have custom view that contains a grid of buttons and set up the button actions to do what you want.
You said "...using button gave me horrible results." Can you elaborate? That should be a good way to go, so any "horrible results" are likely the result of something you did wrong, rather than that being the wrong way to go.
I have developed an IOS 8 custom keyboard. I want to give it "undo" and "redo" functionality, like the default system keyboard. I have tried it in different ways but was unable to find a good solution.
We can interact with a Text Input Object textDocumentProxy with the methods
insertText
deleteBackward
documentContextAfterInput
ocumentContextBeforeInput
But I was unable to find any way of implementing "undo" and "redo" functionality.
I think we can NOT implement these function (undo,redo)
According to https://developer.apple.com/library/ios/documentation/General/Conceptual/ExtensibilityPG/Keyboard.html
Because a custom keyboard can draw only within the primary view of its
UIInputViewController object, it cannot select text. Text selection is
under the control of the app that is using the keyboard. If that app
provides an editing menu interface (such as for Cut, Copy, and Paste),
the keyboard has no access to it. A custom keyboard cannot offer
inline autocorrection controls near the insertion point.
I think there are many case that content of textfield changed and you can not know when it changed, how it changed. If we can not know, we can not know to undo to where too. I think so.
I'm developing Custom keyboard extension like you and I have many problems. (eg: how can we know the current cursor to get current text selection...)
My question: Current text selection in CustomKeyBoardExtension (hope somebody know)
Sorry, the question isn't really clear, but basically I want a button or a label or something like that that says "notifications" and a small red square (like Facebook) that displays the number of notifications that user has (if they have any). How would I go about doing that? I'm not too advanced with UI design in iOS yet. I'm coming from an Android background so feel free to use any comparisons if there are any.
What you are referring to is called a badge. Some native controls have them (tab bar buttons come to mind), but most do not.
If you are using a tab bar controller, you can set the badge value from the UIViewController. Something like this:
[[self tabBarItem] setBadgeValue:#"1"];
If you are looking to implement a custom one, it could be easily accomplished with a UIView and a UILabel. Add a badge view to what ever view based control you are creating, then add a label to that badge view and set its text. There are probably lots of third party ones floating around the web already though.
Im trying to create a popup style notification, which is shown at the top of the screen (using a basic animation). The notification is going to be a simple form with a submit button.
Im trying to figure out how to go about this, and what are the best options i have. I've found this popup library: https://www.cocoacontrols.com/controls/cqmfloatingcontroller
What are the best options for 1. creating the popup and 2. animating to popup
If this is something that you will be reusing a lot, it might be worth subclassing UIAlertView, as you can then automatically use all "popup" methods provided by it,and by customizing it's view you can get the appearance you want.
I want to get the keyboard size without using NSNotification. When I press the plus button, it can replace the keyboard with a custom UIView like this:
Then the plus button is pressed and the view loaded:
How can I achieve this?
I already made same rookie mistake like you want to do here. The problem is you will write a lot only to realize you do not want to avoid standard flow provided you by iOS team. For example you will definitely have a bad time dealing with issue like this one (there is additional bar which is part of standard keyboard for Chinese locale):
I solved this by using other people's work from DAKeyboardControl project. You do not need to attach observer (or if you use DAKeyboardControl - block) directly to your bar with buttons, but to your controller and check what user is trying to do and animate this bar accordingly. In the sources you can see how to get keyboard's animation duration and timing function. It may sound more complicated than it indeed is, just give it a try.
