I am currently working on tvOS app and I am stuck at subclassing textfields. I normally subclass textfields on iOS without problem, somehow tvOS is different.
Here are the bugs that are happening:
textColor is white, after pressing and typing textColor is black
attributed placeholder is white, after typing text, text is black and after clearing text, placeholder appears black and centered horizontally
secure text entry enlarges font
and another random bugs appear and overall textfield is buggy
(It happens even if subclass is very basic - like changed text color after init or in setup method etc.)
Do you have any idea how to fix it or working solution of textfield subclass on tvOS? Thanks

Editing UITextField in tvOS shows a new view where the user can enter in text, and when text entry is done, the user is returned to the previous view. However, I have found that when I return from the text editor, the text I edit does not show up in my text fields. What's going on?
tvOS version 9.1
The reason why it isn't working is because the UITextField is using a non-default background color. Apparently in tvOS, the background color is rendered to the layer after the text has been rendered (Interestingly enough, this does not affect placeholder text). This also happens in interface builder. A bug report has been sent to Apple.
I had a similar issue with shared iOS/tvOS code where the next textfield placeholder text disappeared and became unresponsive.
Make sure that you are NOT setting textField.endEditing(true)
i'm facing a really strange problem: i have some UILabel in my view, which has a black background, so i set their text color to white in Interface Builder in order to see them, the problem is, when i run the app on the simulator or on my iphone with ios7 or iOS 6.1.3 i can update them without problems (for update i mean: myLabel.text = #"Something")
but when i run the app on my sister's iphone 3gs with iOS 6.0 at the moment i update them the font color turns black. It seems that on her phone the label can't remember the color set on IB.
Does anyone of you know why this happens?
Thanks
It sounds like you have set the label "type" to "Attributed" in Interface Builder.
If this is the case then it is not the label that holds the text colour. It is the text itself.
If you replace the text with something else then the default text color of black will be used.
If you want to continue using Attributed text then you need to add a "foregroundColor" attribute to the text before setting it to the label.
The easier way round this is to change the label type to "Plain" in Interface Builder.
Of course, this depends on you having set it to Attributed.
I think you shouldn't use default label color in the interface builder, just provide something else (black color or etc.).
I ran into a similar problem. Was stumping me completely, until I quit and relaunched the simulator. It wasn't enough to just close the window or rebuild. I had to cmd-q, then build and launch again. Magically fixed the issue. Annoying.. but worked for me
I created a custom UIToolbar with UIBarButtonItems as numbers and added it as an inputAccessoryView to the keyboard.
I need to make the UIToolbar match the keyboard color scheme and buttons exactly like standard iPhone keyboard numbers but I can't find anywhere what colors, size or style are used.
Outside of creating images that look like iPhone numbers, is there a way to create them programmatically with system colors, style and size so they match default keyboard buttons? Any guides/resources/examples on this?
I have a few UITextFields and I would like the user to be able to change the font's appearance within those fields.
Right now I have a UIToolbar with 5 buttons used for font controls. One for font name, one for size, one for color and one for alignment.
To change font, I display a picker with the fonts family names, letting the user pick default font for that family.
For the font color, I display another toolbar with a font size slider
For font color, I display an open source color picker
For font alignment, I display a button that cycles through the left/center/right alignment.
Finally there's a close button that hides the toolbar.
Currently all of my code is in one controller, but I would like to have it refactored into a separate, reusable class.
Since I'll be rewriting code, are there any open source font controls like I'm describing above? Maybe I can just plug in something that's already made into my project?
Thank you!
It wouldn't be very hard at all. Instead of pickers use a scroll view with buttons and labels above them using the font. As for size you could do the same!
This would be easy in Xcode 4, not so sure in 3.X.X
I found that the attributed string example by apple does have a table view-like font controller that includes a preview of what fonts look like. I think extending that controller may be the easiest thing to do:
http://developer.apple.com/library/ios/#samplecode/CoreTextPageViewer/Introduction/Intro.html
In my app, I have modified the UILabel and made it underline the text if the phone number or email appears.
but I want to highlight the text when the phone number or email is touched as shown below (I want something like what has been shown below by the dark gray highlight in background of the text "http://www.foodreporter.net".
I want to do this without use of CoreText as my app targets from iOS 3.1.2 onwards. So I don't want to use the CoreText and Attributed strings.
I want to subclass the UILabel and do it somehow. How can it be done?
I don't have the option to use OHAttributedLabel and TTTAttributedLabel.
I suggest for a workaround. What you can do is, use custom UIButton instead of label. Set the default and highlighted image of the button according to your need.(Simple text for default, and highlighted text for highlighted).
Happy Programming
