Recupero dati da plist

Question

Ho un plist e al suo interno un array e quindi un set di elementi del dizionario? Come posso recuperare i dati dal plist al mio array?

Come posso ottenere nomi delle categorie in un array?

Answer 1

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 Codice

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) 

    } 

Swift 3,0

// Read plist from bundle and get Root Dictionary out of it 
var dictRoot: NSDictionary? 
if let path = Bundle.main.path(forResource: "data", ofType: "plist") { 
    dictRoot = NSDictionary(contentsOfFile: path) 
} 

if let dict = dictRoot 
{ 
    // Your dictionary contains an array of dictionary 
    // Now pull an Array out of it. 
    var arrayList:[NSDictionary] = dictRoot?["catlist"] as! Array 
    // Now a loop through Array to fetch single Item from catList which is Dictionary 
    arrayList.forEach({ (dict) in 
     print("Category Name \(dict["category_name"]!)") 
     print("Category Id \(dict["cid"])") 
    }) 
}

1. Ottenere il vostro percorso del file da pacco o da qualsiasi directory
2. Prendi l'array dal dizionario recuperato da plist dizionario

3. vengono memorizzati in ordine di

   NSString *plistFilePath = [[NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES) objectAtIndex:0] stringByAppendingPathComponent:@"test.plist"]; 
   
   NSDictionary *list = [NSDictionary dictionaryWithContentsOfFile:plistFilePath]; 
   NSLog(@"%@",list); 
   NSArray  *data = [list objectForKey:@"catlist"]; 
   for(int i=0; i< [data count]; i++) 
   { 
       NSMutableDictionary *details=[data objectAtIndex:i]; 
       NSLog(@"%@",[details objectForKey:@"category_name"]); 
       NSLog(@"%@",[details objectForKey:@"cid"]); 
   
   }
