iOS How Do I Get the NSString from a UITextField

[kaydell.leavitt]

Hi,

Will somebody help me to get an NSString from a UIText field?

This is what I'm guessing at, but I don't know where to look to see how to do this right.

#import <UIKit/UIKit.h>

@interface MarginCalcViewController : UIViewController {
	IBOutlet UITextField *costDisplay;
	IBOutlet UITextField *priceDisplay;
	IBOutlet UITextField *marginPercentDisplay;
}
- (IBAction) calculateCost;
- (IBAction) calculatePrice;
- (IBAction) calculateMarginPercent;
@end

... then, in the implementation, I have the following which doesn't work:

NSString string = [costDisplay textValue]; <<< warning, may not respond to -textValue


Thanks for taking the time to read my post.

NSString *string = costDisplay.text;

Have you looked at the xcode help documentation, it has all the functions and parameters you can call on all the defined objects.

Thanks for your help.

This is what is working for me now.

NSString *string = [costDisplay text];

if you @synthesize your iboutlets in your implementation you can use the dot notations

@synthesize costDisplay;
@synthesize priceDisplay;
@synthesize marginPercentDisplay;

and that would allow you to access them via

NSString *string = costDisplay.text;
