如何从iPhone sdk中的标签获取文本字段值？

Question

如果我有一个文本字段的标签,那么我如何在iPhone sdk中选择textfield的值

Answer 1

你应该没问题(假设TextField是一个self.view的子视图):

NSString *text = [(UITextField *)[self.view viewWithTag:THE_TAG] text];

Answer 2

试试下面一个

UITextField *textField = (UITextField*)[self.view viewWithTag:tag_Number];
NSString* textString=[textField text];
//Use textString  further

Answer 3

NSString*text = [(UITextField*)[self.view viewWithTag:tag] text];
