How should I pass an int into stringWithFormat

Question

I am try to use stringWithFormat to set a numerical value on the text property of a label but the following code is not working  I cannot cast the int to NSString  I was expecting that the method would know how to automatically convert an int to NSString   What do I need to do here   -  IBAction  increment   id  sender       int count   1      label text    NSString stringWithFormat        count

Is the snippet you posted just a sample to show what you are trying to do   The reason I ask is that you ve named a method increment  but you seem to be using that to set the value of a text label  rather than incrementing a value   If you are trying to do something more complicated - such as setting an integer value and having the label display this value  you could consider using bindings  e g  You declare a property count and your increment action sets this value to whatever  and then in IB  you bind the label s text to the value of count  As long as you follow Key Value Coding  KVC  with count  you don t have to write any code to update the label s display  And from a design perspective you ve got looser coupling
