如何使用objective-C验证由UITableViewCell在自定义文件中创建的多个自定义UItextfield值

Question

I have created an outlet for UItextfield in a custom.h file and created 3 UITextfields using tableviewcell and also assigned tag to each of the textfields. But I don't know how to get those textfield values and also validate them. When all the Textfield values are correct, it should show successful alert message when clicked on a button. I don't want to use 3rd party libraries.

Add a listener to the textfield field change in the cell and create a delegate that is held by the controller. When creating a cell, you need to add a flag to the cell. When the proxy method is implemented, the correctness of the field of the textfiled is determined. The created flag is used to distinguish the cell from the textfield and recorded in the nsarray.
