How to set the decimal point can only input the last two digits

[jiangyongjian]

-(BOOL)textField:(UITextField *)textField shouldChangeCharactersInRange:(NSRange)range replacementString:(NSString *)string； Can we expose a method similar to this

[matmartinez]

Hey @jiangyongjian! You can implement that functionality by adopting the MMNumberKeyboardDelegate protocol. You should take a look at this method:

- (BOOL)numberKeyboard:(MMNumberKeyboard *)numberKeyboard shouldInsertText:(NSString *)text;

You’ll notice the method is very similar to the one you are mentioning from UITextFieldDelegate, although it doesn’t include a range. This is because input views (like this keyboard) are generic and don’t know about the implementation nature of the receiver (it may or not be a editing view that supports ranges).

So, if you’re using an UITextField, you can just grab the current range from the text field directly, and implement your logic accordingly.

Hope it helps!
