Is there a way to pass parameters via the addTarget call as it calls another function?
I've also tried the sender method - but that seems to break as well. What's the correct way to pass the parameters without creating global variables?
@my_button = UIButton.buttonWithType(UIButtonTypeRoundedRect)
@my_button.frame = [[110,180],[100,37]]
@my_button.setTitle("Press Me", forState:UIControlStateNormal)
@my_button.setTitle("Impressive!", forState:UIControlStateHighlighted)
# events
newtext = "hello world"
@my_button.addTarget(self, action:'buttonIsPressed(newtext)', forControlEvents:UIControlEventTouchDown)
view.addSubview(@my_button)
def buttonIsPressed (passText)
message = "Button was pressed down - " + passText.to_s
NSLog(message)
end
Update:
OK, here's a method with an instance variable that worked.
@my_button = UIButton.buttonWithType(UIButtonTypeRoundedRect)
@my_button.frame = [[110,180],[100,37]]
@my_button.setTitle("Press Me", forState:UIControlStateNormal)
@my_button.setTitle("Impressive!", forState:UIControlStateHighlighted)
# events
@newtext = "hello world"
@my_button.addTarget(self, action:'buttonIsPressed', forControlEvents:UIControlEventTouchDown)
view.addSubview(@my_button)
def buttonIsPressed
message = "Button was pressed down - " + @newtext
NSLog(message)
end
