Get int from textField

Question

I am new to cocoa. I am creating a project where I have one text screen and one button. I make a function for the button, where I run my other function, and everything is fine. But I need to take the value of number from textField as a parameter for my function ... for example:

@implementation AppController

- (IBAction)StartReconstruction:(id)sender {
    int RecLine = //here i need something like textField1.GetIntValue();
    drawGL(RecLine);
}
@end

In IB, I only create a text box with numeric forms. But I do not know what to call it from the code :(

thanks for the help

Answer 1

Have you connected a text box between your code and IB? You will need to define ivar and the property in the @interface declaration, for example:

@interface BlahBlah {
    UITextField *textField1;
}
@property (nonatomic, retain) IBOutlet UITextField *textField1;


...
@end

, ivar IB ( google, , ),

[textField1.text intValue];

(, ).

    NSLog (@"Int value is %i", intVal);
}
