I have two NSMutableArray objects, and I would like to have one NSMutableArray instance that is ordered by closest match to a NSString.
Thanks
Define an NSComparator and use something like the Levenshtein distance from string1 as the function for your comparison. If you need a code example. leave a comment and I'll edit this response to include one.

I have saved data to fields in CloudKit and I have queried for the posts by date in decending order and by getting the one at index(0) I have the last post. My question is how do I separate out the various fields and use them to populate the text in various labels in my view. Here is what I have for the latest post query.
<CKRecord: 0x104e5b600; recordID=157F08E2-FF00-42DD-8B89-7CB10FAC81B6:(_defaultZone:__defaultOwner__), recordChangeTag=kk6d3s69, values={ temperature=54, trip=50, level=53, battery=64, date=1-20-2021 20:57:09 }, recordType=MyPoolInfo>
If someone could help me out I would appreciate it. Thanks
I figured this out. This is a dictionary. So I just called the following:
NSLog(#"temperature:%#",[dictionary objectForKey:#"temperature"]) ;
NSLog(#"date:%#",[dictionary objectForKey:#"date"]) ;
NSLog(#"trip:%#",[dictionary objectForKey:#"trip"]) ;
NSLog(#"battery:%#",[dictionary objectForKey:#"battery"]) ;
NSLog(#"level:%#",[dictionary objectForKey:#"level"]) ;
I could then fill in the label.text like this:
self.DateLabel.text =[dictionary objectForKey:#"date"];
in case anyone needs to know.

What are some situations where NSDictionary is preferred over NSMutableDictionary? I feel like it is always nice to have the option to change values in the dictionary.
You might like the option to manipulate the dictionary, but you would not like it if other code manipulated it behind your back. An instance variable typed as an NSMutableDictionary would allow that very thing to happen.
The same is true of all the other immutable/mutable pairs.
NSdictionary working like constant but in nsmutalbledictionary we can add or remove object at any where after declaration.Another point is in NSdictionary we only assign that means we only get new dictionary that you assign.......

I'm trying to run a for loop and every time a loop runs through a UIButton is allocated and initialized. The issue is that all of these buttons need different names. Is there a way to name the button based on the value of the integer in the for loop?
Is sounds like you want to put the buttons in an NSArray. Items in the array can be referenced by an index into the array.

I have an array ['f_1', 'f_10', 'f_3', 'f_2']
I want to sort this array in ascending order using ruby one line code.

['f_1', 'f_10', 'f_3', 'f_2'].sort_by { |s| s[/\d+/].to_i }
# => ["f_1", "f_2", "f_3", "f_10"]

arrayName = #"Blah";
NSArray (array(arrayName))= [something or other];
After defining a variable name called "arrayName", which I wish to the name of an array to be it's condition. Is the code defining the NSArray possible?
P.S. The code is pseudo code.
sounds like you want to use an NSMutableDictionary then you can have your variable names as the keys, and assign them their specific values.
but what you are asking isnt possible
