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.

How do I stop iteration and return an error when Iterator::map returns a Result::Err?
(4 answers)
Closed 6 years ago.
I have an Iterator<Item=io::Result<u8>> that I'd like to convert to io::Result<Vec<u8>>.
iter.map(|x| x.unwrap()).collect::<Vec<u8>>()
will give me the Vec<u8> but how can I keep the Err part in case of an error?
#aspex thanks for you help, it's
let fold: io::Result<Vec<_>> = iter.collect();

How to convert 'struct' to '&[u8]'?
(2 answers)
Closed 6 years ago.
I'd like to serialize my struct to binary and de-serialize it on the other end of the pipe. Is there a way to achieve this with the serialize crate? It seems to only support JSON, hex and base64.
I would suggest bincode.
It provides encode() and decode() functions which operate on anything with RustcEncodable & RustcDecodable traits, which can generally be #[derive]d, and return Vec<u8>.
It has a few quirks (isize and usize become i64 and u64, for example), but they are mostly there to improve portability and it tends to work as you would expect.

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.)
