SWIFT 2:遍历JSON数组
我从网址获取此json,返回的JSON为:
[{"id":1,"name":"Mary"},{"id":2,"name":"John"}]
我想在IOS的TableView中显示名称。
我的Swift2代码是:
class ViewController: UIViewController, UITableViewDelegate { var NumberOfPersons = 0
var NameOfPerson = [String]()
override func viewDidLoad() {
super.viewDidLoad()
parseJSON()
}
func parseJSON(){
do {
let data = NSData(contentsOfURL: NSURL(string: "http://zzzzzz.com/API/name.php")!)
let jsonResult = try NSJSONSerialization.JSONObjectWithData(data!, options: NSJSONReadingOptions.MutableContainers)
let NumberOfPersons = jsonResult.count
**LOOP THROUGH THE JSON ARRAY**
} catch let error as NSError {
print(error)
}
}
}
如何遍历JSON数组以在表视图的单元格中放置哪个名称?
回答:
该变量jsonResult
是一个字典数组,因此您可以使用
for anItem in jsonResult as! [Dictionary<String, AnyObject>] { // or [[String:AnyObject]] let personName = anItem["name"] as! String
let personID = anItem["id"] as! Int
// do something with personName and personID
}
在 ,未指定的JSON类型已更改为Any
for anItem in jsonResult as! [Dictionary<String, Any>] { ... // or [[String:Any]]
