XCode UITextField

Question

Inside the .h:

@interface MyController : UIViewController<UITextFieldDelegate> {

   IBOutlet UITextField *phonenum;
   IBOutlet UITextField *email;
}

@property (nonatomic, retain) UITextField *phonenum;
@property (nonatomic, retain) UITextField *email;

-(IBAction) btnClicked: (id) sender;
@end

Inside the .m:

-(IBAction) btnClicked: (id) sender{


NSString *str = [[NSString alloc]init];
NSLog(@"str=%@",str);  //this contains valid value
email.text=str;  /// does not set the value
[[self email] setText: str];  // does not set the value
}

What am i doing wrong where it does not set the UITextField value using the variable str that is NSString? Is this some kind of Inteface Builder setting? I have delegate link to file owner.

Answer 1

Maybe you forgot to connect your outlets with the interface in Interface Builder

If you don't know how to do that, please see :

It seems that str is nil, so nothing happens. And your 2 last lines do the same thing. You should write

NSString *str = email.text;

And then do something with str, like

user.email = str;

or directly

user.email = email.text

if you want to update a user email with the text in your UITextField.
