I really want to make a keyboard that is the UIKeyboardTypeNumberPad but instead of it showing a 4 in a textfield when pressing the 4 button, i want it to highlight the G for about 5 seconds and while its highlighted, if i press again it goes to h then to i, and for all letters, so 2 would start A then b then c if clicked multiple times? i found out on IOS they have a built in one that does this, but its not exactly the UIKeyboardTypeNumberPad and its for japanese, it will show, and type in US but still some japanese around and is hard to use because its not a true full UIKeyboardTypeNumberPad. like 0 is space or go to next letter, not on the japanese one though. so how could i code this for my application?
I don't think this is a good approach, but technically you can. Work not with keyboards, but with input fields. I mean that, for example, UITextViewDelegate defines –textView:shouldChangeTextInRange:replacementText: method. When user tries to change text in UITextView, this method will be called. Then you can change text manually and return NO to ignore user input.
ReplyDeleteIn example below when user types '0', 'G' will be added instead (to illustrate my idea).
- (BOOL)textView:(UITextView *)textView shouldChangeTextInRange:(NSRange)range replacementText:(NSString *)text
{
NSString *correctReplacement = [text stringByReplacingOccurrencesOfString:@"0" withString:@"G"];
textView.text = [textView.text stringByAppendingString:correctReplacement];
return NO;
}
The correct way to do this is to create your own “keyboard” view with the buttons and actions you want, and assign it to the text field's inputView property. Then the system will display your keyboard instead of the normal system keyboard. The keyboard view (or view controller) will need a reference back to the text field, so it can use the UITextInput methods to respond to the user's touches.
