Question

I have a custom button which I want to assign a string and then pass the button as a parameter in a @selector. For this reason, in the header files CustomButton I put a property “name”. However, when I assign the string to button, I get this error.

'NSInvalidArgumentException', reason: '-[UIButton setName:]: unrecognized selector sent 
to instance 0x8484560'

What does it mean?

The code in CustomButton.h:

 @interface CustomButton : UIButton

 @property (nonatomic, strong)NSString * name;

 @end

The code in CustomButton.m:

 @synthesize name;

In MapViewController.m

CustomButton *rightButton = [CustomButton buttonWithType:UIButtonTypeInfoLight];

NSLog(@"The button is %@", rightButton);
/*The button is <UIButton: 0x8484560; frame = (0 0; 18 19); opaque = NO; layer = 
  <CALayer: 0x8484670>>*/

rightButton.name = self.nameTable; //the error is here

Answer 1

Change the button type to UIButtonTypeCustom.

CustomButton *rightButton = [CustomButton buttonWithType:UIButtonTypeCustom];
