Shortcuts in Objective-C to concatenate NSStrings

Is it possible to add on to the text of a label without changing existing text? I'm new to mac development in Xcode so any help is appreciated.
Yes and no. Basically, you replace the text with a new string that includes the old text
self.myLabel.text = [self.myLabel.text stringByAppendingString:#"more stuff"];

ios programming - Data argument not used by format string
(2 answers)
Closed 6 years ago.
Hi there I'm trying to do an NSLog but what I want to see is what it's inside of my dictionary like this.
NSLog(#"diccionario", diccionario);
And this warning appears:
Data argument not used by format string
The diccionario object contains data from a server so like I said I want to print in the console the info that diccionario contains, because is not printing anything.
Thanks.
NSLog(#"diccionario : %#", diccionario);
Should be the solution.

what does dollar sign mean in objective-c?
(2 answers)
Closed 9 years ago.
I'm still new to objective-c I went through a code example from git hub and saw '$' notation before parameters for example:
titleLabel.$height = TITLE_HEIGHT;
can some one explain the difference between titleLabel.$height and titleLabel.height
The property happens to include a dollar sign in its name, it has no significance.
For Example:
#property int $height;

Objective C - Why do constants start with k
(6 answers)
Closed 9 years ago.
I have always wondered, when you define something such as a string (or anything for that matter), why do people put a 'k' ahead of the defined name?
e.g. #define kHello = #"Hello"
What's that 'k' all about?
I'm pretty sure the 'k' is short for constant. (Don't ask me why it's a k.)
