Question

Swift 2 NSMutableArray() value don't shows in variable
My codes here.
var detail_desc : NSMutableArray! = NSMutableArray()
when i added this code gives me
label.text = self.detail_desc.description
And my array output
{
{
"cat_img" = "http://asdasd.com/asd.jpg";
"cat_name" = Good;
id = 45;
"is_active" = 3;
"last_update" = "2015-11-21 15:32:42";
}
}
I want to use array item to variable ;
label.text = cat_img
label2.text = cat_name
any idea ?

Answer 1

There's a lot wrong with what you have, I'll try to tackle it one by one:
Underscore
Underscore naming isn't common in cocoa and reads very strange. Change detail_desc to detailDesc.
Note: There are situations in which we use the underscore, one of which is extensions on core classes. In these cases, it is prefix - underscore - name. ie: my_specialFunctionOrVariable
NSMutableArray
NSArray and NSDictionary classes shouldn't be used in Swift unless absolutely necessary. They behave slightly differently, and you lose all of the type safety that makes swift so great.
Naming
In general, naming schemes like label, label2, and detailDescription are very confusing. They don't tell me anything about what each represents. Try something like catImageUrlLabel, and catNameLabel to be more specific. Also, detailDescription could be catInformation
Single Object Encapsulated In Array
You really have a dictionary as the single object in an array, I think you should just have the dictionary reference. (unless there could be more in the future). I'll move forward assuming there won't be.
How it might look
Change your variable to something like this:
var detailDescription: [String : AnyObject] = ...
Then, in your UI setting code, do something like this:
label.text = detailDescription["cat_img"] as? String
label2.text = detailDescription["cat_name"] as? String
Modelling Objects
Json is dirty and we prefer not to deal with it as much as possible. Consider modeling your Cat json to a Cat object:
struct Cat {
let imageUrl: String
let name: String
let id: Int
// etc.
}
Then parse the json into this model when you receive it and pass that to your view controller.
Then our code might look like this:
nameLabel.text = cat.name
imageUrlLabel.text = cat.imageUrl
// etc.
This is very clear what everything represents, and will make for a more readable, and more maintainable code base.
Hope this gets you off on the right track.
