ios – 从plist中检索数据

如何在一个数组中获取类别名称？

解决方法 Objective-C的

// Read pList from bundle and get Root Dictionary out of itNSDictionary *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"]);}];

迅速

// Read pList from bundle and get Root Dictionary out of itvar 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 DictionaryarrayList.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代码

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 itvar 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"])")    })}
