Fixed by this pull request - #19 Reproduce bug you can by demo project:

• Assign SKView on root View in VC.

• Embed VC with another root VC for navigation

• Try to push/pop. You will see that VC not deallocating

Hi,

Thanks for great validation text field, it would be nice if you tell how to use with UITableviewCell with uitextfield, i tried to use the way it has been shown in demo, but when hit on error icon it's not displaying the error dialog

When i use this textfield inside a table view cell app gets crash(@TextFieldValidator.m line 291) with following info

*** Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: 'Unable to parse constraint format:
Unable to interpret '|' character, because the related view doesn't have a superview
H:|-0-[popUp]-0-|

libc++abi.dylib: terminating with uncaught exception of type NSException

I tried to implement TextFieldValidator in a swift project. It was added and working smooth for validation portion, but when I clicked on the error, it crashed. The error was related to superview. I added a screenshot with it, have a look.

Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: 'Unable to parse constraint format: Unable to interpret '|' character, because the related view doesn't have a superview
H:|-0-[popUp]-0-|

how to set this class on alertview textfield.

If you would like lots of people to use this neat project, then a license like MIT would be a really good idea - it will stop people worrying about ownership or potential usage claims later!

I've a form page, with more than 6 cells. each cell have a textfield with a single reusable identifier.

i've successfully implemented the validation on a submit button click when i've less than 6 cells. in this case all the cells are visible on view.
problem arises when there are some cells out of the view, so calling [tableView cellForRowAtIndexPath:] returns a nil cell.
since i can not get a cell which is out of the view, it can't be checked for validation.

any advice on this problem?

Is possible create pod spec file to include this tool in cocoapods
