推荐答案

您可以检查 Default 是否等于 1 并将这些值添加到数组中.

You can check if Default equals 1 and add those values to an array.

var defaultArray = [NSDictionary]() if let addressArray = jsonObj!.value(forKey: "address") as? NSArray{ for array in addressArray { if let addressDict = array as? NSDictionary{ if let Default = addressDict.value(forKey: "default"){ if Default == 1 { defaultArray.append(addressDict) } } } } }
