Question

Is it possible to send extra parameters when I instantiate this button class, like so:?

BttClass *myButton = [[BttClass alloc] init];

If so, what is the correct syntax? I have been trying all sorts!
I would like to send a BOOL and a string.
Thanks.

Extend UIButton by subclassing it.

//MyButton.h
@interface MyButton : UIButton {

}

@property (nonatomic, strong) NSString* aString;
@property (nonatomic, weak) BOOL aBool;

You need to define an initialiser method

-(id)initWithStringValue:(NSString *)stringValue andWithBoolValue:(bool)boolValue;

Then implement the initialiser method

//MyButton.m
-(id)initWithStringValue:(NSString *)stringValue andWithBoolValue:(bool)boolValue {
    self = [super init];
    if (self) {
        self.aString = stringValue;
        self.aBool = boolValue;
    }
    return self;
}

In a calling class your code would look like

MyButton* myButton = [[MyButton alloc] initWithStringValue:@"tralala" andWithBoolValue:YES];
