我想让所有用户'存储在cloudkit
中的位置,然后由每个设备下载。我在storeLocation
中的代码上标记了我收到错误:
"无法转换类型'(NSError?,[CKRecord]?)' (又名'(可选,可选>)')预期参数类型'(错误:NSError ?,记录:[CKRecord]?) - >空隙'"
//saves location in cloud kit //currently works well:
var locArray = [CKRecord]()
func storeLocation(location:CLLocation) {
let locationRecord = CKRecord(recordType: "location")
locationRecord.setObject(location, forKey: "location")
let publicData = CKContainer.defaultContainer().publicCloudDatabase
publicData.saveRecord(locationRecord) { (records, error) in
if error != nil {
print("error saving locations: \(error)")
} else {
print("Locations saved: \(records)")
loadLocation((error, self.locArray)) //where I get error******
}
}
}
//fetches location from cloud kit:
func loadLocation(completion: (error:NSError?, records:[CKRecord]?) -> Void)
{
let query = CKQuery(recordType: "Location", predicate: NSPredicate(value: true))
CKContainer.defaultContainer().publicCloudDatabase.performQuery(query, inZoneWithID: nil){
(records, error) in
if error != nil {
print("error fetching locations")
completion(error: error, records: nil)
} else {
print("found locations: \(records)")
completion(error: nil, records: records)
}
}
}
答案 0 :(得分:2)
我相信而不是:
loadLocation((error, self.locArray))
你需要这样称呼:
loadLocation() { (error, records) in
// do something here with the returned data.
}
