How can i get the textfield value from tag in iPhone sdk?

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

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

Answer 3

Try below one

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

Answer 4

Use:

UITextField *textField = (UITextField*)[self.view viewWithTag:100];

NSLog(@"%@",textField.text);

You need to replace 100 by your own tag.
