How to produce the character ŵ on iPad using external keyboard? I could type other special characters like ö, ü and ä but not ŵ. I typed a lot in a language, where the character ŵ frequently occurs.
I tried the Text Replacement (Settings > Keyboard > Text Replacement), however the iPad replaces the whole word instead of a single character.

I am new to Swift and this is my first application. I essentially want a user to enter two numbers, that I can use for some calculations. For the text fields I used the option "Decimal Pad" as keyboard type. With the simulator it works well - on my phone, however, the dot is shown as a comma, which causes the app to crash. Is there an easy fix for this problem? I don't want any global changes for the location or the keyboards used, but just a fixed decimal pad with dot instead of comma.
Thank you!
My app uses unicode characters. These characters (not the actual codes) are pasted directly into a PLIST file and then imported.
Some of them are not appearing correctly in UILabel and UIButton
When I print them to the log in Xcode they appear normal, but when displayed on the iPhone/Simulator some of the characters turn into an "alien in a box".
See image for example of problem (screenshot from UIButton titles)
My guess is that the font you are using does not define these characters. Select a font (or build one into your app) that includes the characters you need.
When I write arabic text containing the letter kasra (unicode character 0x650, phonetic equivalent i) to a button, the kasra is not displayed. Thus, the word mumkin appears as mumkn. If I inspect the NSString in Xcode, the kasra is present, but the kasra is not displayed in the iPhone simulator or on a real iPad. The other two short vowels (fatha and damma) are displayed correctly.
The arabic letter kasra (unicode character 0x650) is missing from all of the built-in IOS7 fonts that i have tried.
The solution was to build a different font into my app- I used AGA-Rasheeq-Bold.
This may be a bug. I just tried it in the storyboard editor and it does not seem to work. I created a string in the MAC Notes application, copied and pasted. It displays correctly in the left hand properties panel, but not in the button itself. Could you provide the exact Unicode string? You may need to open a bug report with Apple.
I can confirm that it works correctly in a Label field, but not a Button (IOS 6.1 and Xcode 4.6.3)
Try attributed text. This seems to work around the issue.
I've always thought it was great that I could use simple iconic unicode characters in a string when I needed an arrow or a bullet or whatever. The glyphs would render in the same color as the rest of the string with a nice simple and clean icons. I could preview how they'd look by using the Mac's "Special Characters" dialog on the Edit menu in XCode.
In iOS5, these glyphs render in full color and aren't simple and clean. I believe these are Emoji icons?
I'm looking for an explanation of this change, and ideally how to force iOS5 to revert to the iOS2 - iOS4 behavior.
Here's an example: #"← left arrow, right arrow → airplane ✈";
Edit:
Apparently the NSString UIKit extensions for rendering text (drawAtPoint: / drawInRect:) don't exhibit this behavior. So perhaps it is a UILabel thing? Specifically I've noticed it inside a UISegmentControl segment button, and in a UILabel.
This isn't a bug, it's down to the font used. When you use a character in a string that isn't available in the chosen font, iOS automatically substitutes a glyph from another font.
The system font (Helvetica) doesn't have those characters in it, so I'm guessing that Apple have have changed the list of fallback fonts so that Emoji ranks above whatever it was using previously for the fallback for those characters.
To fix it, find a font that a) has the version of the characters you want in it, and b) is available on iPhone, and set your label to use that instead of the default system font.
Alternatively, you could just make a UILabel subclass and override the drawRect method so it uses the drawAtPoint/drawInRect methods to draw the string.
On the iOS platform, I have a UITextField where I am using the ASCII keyboard layout. I notice (like the keyboard works in other apps) that when I type space + space, a period '.' is inserted into the text field. This is all normal iOS stuff...
But can I configure the text field or the keyboard somehow so that this "two spaces == period" behavior is turned off?
