Retrieve data from plist

I have a plist and inside that an array and then set of dictionary elements? How can I retrieve data from the plist to my array?

plist

How can I get category names in one array?

Answer

Objective-C

// Read plist from bundle and get Root Dictionary out of it
NSDictionary *dictRoot = [NSDictionary dictionaryWithContentsOfFile:[[NSBundle mainBundle] pathForResource:@"data" ofType:@"plist"]];

// Your dictionary contains an array of dictionary
// Now pull an Array out of it.
NSArray *arrayList = [NSArray arrayWithArray:[dictRoot objectForKey:@"catlist"]];

// Now a loop through Array to fetch single Item from catList which is Dictionary
[arrayList enumerateObjectsUsingBlock:^(id obj, NSUInteger index, BOOL *stop) {
    // Fetch Single Item
    // Here obj will return a dictionary
    NSLog(@"Category name : %@",[obj valueForKey:@"category_name"]);
    NSLog(@"Category id   : %@",[obj valueForKey:@"cid"]);
}];

Swift

// Read plist from bundle and get Root Dictionary out of it
var dictRoot: [NSObject : AnyObject] = [NSObject : AnyObject].dictionaryWithContentsOfFile(NSBundle.mainBundle().pathForResource("data", ofType: "plist"))
// Your dictionary contains an array of dictionary
// Now pull an Array out of it.
var arrayList: [AnyObject] = [AnyObject].arrayWithArray((dictRoot["catlist"] as! String))
// Now a loop through Array to fetch single Item from catList which is Dictionary
arrayList.enumerateObjectsUsingBlock({(obj: AnyObject, index: UInt, stop: Bool) -> Void in
    // Fetch Single Item
    // Here obj will return a dictionary
    NSLog("Category name : %@", obj["category_name"])
    NSLog("Category id   : %@", obj["cid"])
})

Swift 2.0 Code

var myDict: NSDictionary?
    if let path = NSBundle.mainBundle().pathForResource("data", ofType: "plist") {
        myDict = NSDictionary(contentsOfFile: path)
    }
    let arrayList:Array = myDict?.valueForKey("catlist") as! Array<NSDictionary>
    print(arrayList)

    // Enumerating through the list
    for item in arrayList  {
        print(item)

    }
