How to move from one textFields to next textField on tabBar button's Action

In my iphone app I have 6 textFields, and a tabBar (having 3 buttons Next,Previous,Done).

All I need to do is w开发者_JS百科hen I click on next button, the focus should move from first textField to next textField.

On Next button's IBAction I write the following code :

if ([txt1 isFirstResponder]==YES) {

    NSLog(@"TXT1");

    [txt1 resignFirstResponder];

    [txt2 becomeFirstResponder];

}
else if ([txt2 isFirstResponder]==YES) {

    [txt2 resignFirstResponder];

    [txt3 becomeFirstResponder];

}
else  if ([txt3 isFirstResponder]==YES) {

    [txt3 resignFirstResponder];

    [txt4 becomeFirstResponder];

}
else  if ([txt4 isFirstResponder]==YES) {

    [txt4 resignFirstResponder];

    [txt5 becomeFirstResponder];

}
else  if ([txt5 isFirstResponder]==YES) {

    [txt5 resignFirstResponder];

    [txt6 becomeFirstResponder];

}
else  if ([txt6 isFirstResponder]==YES) {

    [txt6 resignFirstResponder];

}

when I use this code NSLog prints infinite times.

What can be done??

Might be because if txt1 isFirstResponder, you're setting txt2 as firstResponder, then checking if txt2 is first responder. You should put a break; at the end of each if statement.

Oops, its my mistake. I Forgot to connect textField's delegate to Files Owner.. Thank you guys.

Actually, in each if statement, you do not need the resignFirstResponder, since you do not want to dismiss the keyboard each time you move to another field.

Instead, leave the only resignFirstResponder in txt6
