我正在研究REST API管理器.这是一个错误,我无法解决它.我得到的错误在下面突出显示.
import Foundation
import Alamofire
import SwiftyJSON
class RestApiManager {
var resources: JSON = [
"resources": [
"resourceA": []
]
]
let apiUrl: String
let apiUsername: String
let apiPassword: String
init(apiUrl: String,apiUsername: String,apiPassword: String) {
self.apiUrl = apiUrl
self.apiUsername = apiUsername
self.apiPassword = apiPassword
getApiResourceA() { responSEObject,error in
let resourceA = JSON(responSEObject!)
self.resources["resources"]["resourceA"] = resourceA
}
}
func collectDataFromApi(completionHandler: (responSEObject: NSDictionary?,error: NSError?) -> ()) {
prepareHttpRequest(completionHandler)
}
func prepareHttpRequest(completionHandler: (responSEObject: NSDictionary?,error: NSError?) -> ()) {
let alamofireRequest = Alamofire.request(.GET,"\(self.apiUrl)")
alamofireRequest.authenticate(user: self.apiUsername,password: self.apiPassword)
alamofireRequest.responseJSON { request,response,responSEObject,error in
completionHandler(responSEObject: responSEObject as? NSDictionary,error: error)
}
}
func getAllResources() -> JSON {
return self.resources
}
func getApiResourceA(completion: (responSEObject: NSDictionary?,error: NSError?) -> ()) {
collectDataFromApi() { responSEObject,error in
completion(responSEObject: responSEObject,error: error)
}
}
}
当我打电话给这个班级获取资源时：
override func viewDidLoad() {
super.viewDidLoad()
if record != nil {
let url = record?.url
let username = record?.username
let password = record?.password
let restApiManager = RestApiManager(apiUrl: url!,apiUsername: username!,apiPassword: password!) // This line seems buggy
let delay = 10.0 * Double(NSEC_PER_SEC)
let time = dispatch_time(DISPATCH_TIME_NOW,Int64(delay))
dispatch_after(time,dispatch_get_main_queue()) {
let Resources = restApiManager.getAllResources()
let ResourceA = Resources["resources"]["resourceA"]
}
}
}
我评论的线打印：
Thread 1: breakpoint 2.1
我需要修复错误的建议.任何建议都非常感谢
