zftokenfield's Issues

If reduce height than 40 then its corner radius is effected.

If TokenView height is 40 then it works fine but if i change it to 30 then it becomes edgy. I am unable to find it corner radius code. Can you please guide me what should i do?

Token textfield frame is shifted inward with empty placeholder

Hi,

Thanks for the wonderful work you have done.

If the token's textfield placeholder text is empty , the textfiled x origin is shifted inwards. ie if i set the placeholder text empty , and i start editing the text field, the initial text are not visible not . But however if i set 11 spaces or any anything in the range of 11 as the placeholder , the initial text is visible (frame is not shifted) .

iOS 7.1 support ?

Hi there,

just a small question, why are you only supporting iOS 7.1, and not 7.0 ?

Regards,

Can you give an option to disable editing?

Sometimes, you need to show a list of items, without adding and removing features.

Possible solution:

In ZFTokenField.h file

- (BOOL)tokenFieldShouldBeginEditing:(ZFTokenField *)textField;

In ZFTokenField.m file

- (BOOL)textFieldShouldBeginEditing:(ZFTokenTextField *)textField {
    if ([self.delegate respondsToSelector:@selector(tokenFieldShouldBeginEditing:)]) {
        return [self.delegate tokenFieldShouldBeginEditing:self];
    }

    return YES;
}

Crashing Inside TableViewCell

I have added ZFTokenView inside a UITableViewCell. At run time clicked inside the textfield and popped back to my previous view controller. Then again I came back to the view controller that has the token filed. It crashes the app with the following backtrace. Please help me to resolve.
