how to use same field to take data into uitextfield and out the result on label

i am writing an application for t开发者_Go百科emperature converter in iphone i want use the same field for data input and output i.e single field which has properties of both uitextfield and uilabel. plz help. thanks

try :

-(IBAction)clculate
{
NSString *input =yourtetfield.text;  
Made some caculation   
................  
................  
 yourtetfield.text= result;  
}  

Note result is a string .

Just Try this....write this code on your buttonclick...

 -(IBAction)btnGoClicked:(id)sender
 {
     NSString *strTxtFiled = txtField.text;
     int intdata = [strTxtFiled intValue] * 2;
     txtField.text = [NSString stringWithFormat:@"%d",intdata];
 }

Here txtField is your TextField and I had done some calculation..you can do your calculation as explained here...

well,you can use uitextfield. It has an input (with the text property) and an output (with setText: ) Documentation of uitextfield

'myLabelVariable.text = myUITextfield.Text; is that what your on for?
