我已经将
Xcode从7更新为8,将
Swift从2.3更新为3.
我在让名字=候选人[“候选人姓名”]时得到这个错误！：
type nsfastenumerationiterator.element aka any has no subscript members
let url = URL(string: "https://website.com")
let data = try? Data(contentsOf: url!)
var tmpValues = try! JSONSerialization.jsonObject(with: data!,options: JSONSerialization.ReadingOptions.mutableContainers) as! NSArray
tmpValues = tmpValues.reversed() as NSArray
reloadInputViews()
for candidate in tmpValues {
if ((candidate as? NSDictionary) != nil) {
let names = candidate["CandidateName"]!
//self.values.append(candidate["CandidateName"])
self.values.append(name!)
print(name)
}
}
我认为你的循环应该是这样的.这对我有用.但请确保var tmpValues.

if ((candidate as? NSDictionary) != nil) {
let names = candidate["CandidateName"]! as? String
//self.values.append(candidate["CandidateName"])
self.values.append(name!)
print(name)
}
}
