當我嘗試在我的iPhone運行,下面的代碼,我收到以下錯誤曖昧使用標錯誤
rrr.swift:356:72: Ambiguous use of 'subscript'
奇怪的是它只有當我想要運行的應用情況在電話上,在模擬器上,但它工作正常。
有3行導致錯誤的地方。我在下面的代碼中用大寫字母指出了它們。 我嘗試訪問JSON數組內的數組中的屬性,我懷疑我是以錯誤的方式做它,但不知道如何解決它。
如何在沒有下標錯誤的情況下檢索這些屬性?
self.restApi.getSchoolDetails(schoolId) {responseObject, error in
// use responseObject and error here
self.schoolDetailsCollection = NSDictionary(dictionary: responseObject! as! [String : AnyObject])
print(self.schoolDetailsCollection)
if let response = responseObject as? NSDictionary {
//parse the response object
self.schoolDetailsList = (response as? NSDictionary)!
//assigning all values to shareData class
self.shareData.sco_id = response["result"]!["sco_id"] as!NSInteger
self.shareData.address = response["result"]!["address"] as!String
self.shareData.name = response["result"]!["name"] as! String
print("school name")
print(self.shareData.name)
self.shareData.intro = response["result"]!["intro"] as! String
self.shareData.sell_point = response["result"]!["sell_point"] as! String
self.shareData.city = response["result"]!["city"] as! String
self.shareData.cou_id = response["result"]!["cou_id"] as! String
//get images from the nested array in the json array
/THESE THREE LINES CAUSE THE ERROR SUBSRCIPT
self.shareData.image1 = response["result"]!["images"][0]! as! String
self.shareData.image2 = response["result"]!["images"]![1] as! String
self.shareData.image3 = response["result"]!["images"]![2] as! String
print(self.shareData.image1)
print(self.shareData.image2)
print(self.shareData.image3)
//open next controller after all info has been set correctly
//info is being passed by Singleton class Sharedata
