Disable Spell Check in iOSTextField

Targets iOS

Can spell check be disabled in an iOSTextField in an iOS app?

If the iOSTextField is used to enter a URL, spell check is constantly in the way.

the answer to the question you asked is… YES, spell check can be disabled in an iOS app…
The question you should ask, is
How do I disable spellcheck in Xojo for iOS?

If you switch to using an iOSLibTextField from @Ulrich Bogun available on Git then you can turn off spell checking with:

me.spellCheckingType = AppleTextField.UITextSpellCheckingType.No

And I also suggest you might want to do this:

me.autoCorrectionType = AppleTextField.UITextAutocorrectionType.No

Declare sub setAutocapitalizationType_ lib "UIKit.framework" selector "setAutocapitalizationType:" (obj_id as ptr, value as boolean) setAutocapitalizationType_(textfield.handle, false)

I would assume the same works for

  • autocapitalizationType
  • spellCheckingType
  • isSecureTextEntry
  • autocorrectiontype

The last two are boolean (although Xcode wants .yes or .no for SpellCheck , but true or false for isSecureTextEntry (ie. Password)
and autoCap has a whole list of enums connected to it…

iOSLib is outdated. Better use GitHub - UBogun/Xojo-AppleLib: A library extending Xojo‘s macOs and iOS features – 64 bit and new framework compatible. if you want to.

Jrmie Leroy’s solution works fine to turn off capitalization when pasted into the iosView Open event.

Declare sub setAutocapitalizationType_ lib “UIKit.framework” selector “setAutocapitalizationType:” (obj_id as ptr, value as boolean)
setAutocapitalizationType_(textfield.handle, false)

Any idea how to create a similar declare to turn of autocorrect. The following code compiles, but doesn’t work.

Declare sub setAutocorrectionType lib “UIKit.framework” selector “setAutocorrectionType:” (obj_id as ptr, value as boolean)
setAutocorrectionType(WorkbookURLEdit.handle, false)

declare sub autocorrectionType_ lib "UIKit.framework" selector "setAutocorrectionType:" (obj_id as ptr, autocorrectionType as Integer) autocorrectionType_(textfield.Handle, 1)

The integer value can be one of the following:
0: default
1: no
2: yes

Hi Jeremie, I’m never great with Declares; how do I implement the declare you have shown into a project? I’d like all textfields to be non capitalizing and non autocorrect.

Hi Boudewijn,

I too struggled for many years with declares, and finally got an enlightenment 3 years ago :slight_smile:

First create a subclass of iOSTextField:

  • Xojo Insert Menu > Class
  • Define the name of your TextField Subclass, ie: MyTextfieldSubclass
  • Set Super to iOSTextField

Then implement the Open event of your Textfield subclass and add the following code:

Declare sub setAutocorrectionType_ lib "UIKit.framework" selector "setAutocorrectionType:" (obj_id as ptr, value as Integer)
Declare Sub setAutocapitalizationType_ Lib "UIKit.framework" selector "setAutocapitalizationType:" (obj_id As ptr, value As Integer)

setAutocorrectionType_(self.Handle, 1)
setAutocapitalizationType_(self.Handle, 0)

RaiseEvent Open

Finally, Add a new Event Definition to the class and name it Open

In your project, whenever you need a textfield with no Autocorrect and no Autocapitalization, use your TextField subclass.
