- (IBAction)buttonPressed:(id)sender {
if([textbox1 isFirstResponder]){
//Cursor on textbox1
texbox1.text=#"User";
}
else if([textbox2 isFirstResponder]){
//Cursor on textbox2
textbox2.text =#"Admin";

NSLog(#"None of them have cursor");
}

Answer 2

Set Tag to your textfields
Implement UITextFieldDelegate in your class
Use this methods
- (void)textFieldDidBeginEditing:(UITextField *)textField {
if (textField.tag == your tag) {
selectedTextField = textField; //selectedTextField is an UITextfield variable
}
}
Use it in your IBAction
- (IBAction)buttonPressed:(UIButton *)sender {
selectedTextField.text = #"abc";
}
//Edit: something wrong with StackOverFlow's code function, doesn't display properly

Answer 3

If I understand your question correctly, I think the below code is what you want:-
- (IBAction)buttonPressed:(UIButton *)sender {
if(self.texbox1.isFirstResponder){
self.texbox1.text=#"User";
[self.texbox1 resignFirstResponder];
}
if(self.texbox2.isFirstResponder){
self.texbox2.text=#"Admin";
[self.texbox2 resignFirstResponder];
}
}
I am not sure why you want to implement as above though as it is a bit funny.

Answer 4

UITextField is a subclass of UIResponder which allows you to perform checks including isFirstResponder which may be what you are looking for. However you will need to understand how the responder chain works and if this is really the behavior you are trying to detect.

Answer 5

Use isFirstResponder to check which textbox is active.
- (IBAction)buttonPressed:(id)sender {
if([textbox1 isFirstResponder]){
texbox1.text=#"User";
}
else if([textbox2 isFirstResponder]) {
textbox2.text =#"Admin";
} else {
// What should happen when neither textbox1 nor textbox2 is active?
}
}
