ios – 无法将类型'(Bool,NSError！) – > Void’的值转

导读：自从在 Xcode 8(Beta 1)和 Swift 3上升级后,我在此行中出错： account.requestAccessToAccounts(with: accountType,options: nil,completion: {(success: Bool,error: NSError!) - Void in 它说： Cannot convert value of type ‘(Bool,NSError!) - Void’

自从在
Xcode 8(Beta 1)和
Swift 3上升级后,我在此行中出错：
account.requestAccessToAccounts(with: accountType,options: nil,completion: {(success: Bool,error: NSError!) -> Void in
它说：
在那之前,我定义了“account”和“accountType”： let account = ACAccountStore()
let accountType = account.accountType(
withAccountTypeIdentifier: ACAccountTypeIdentifierTwitter)
这是我的(使用Xcode 7和Swift 2)代码： func getTimeline() {
//https://api.twitter.com/1.1/statuses/user_timeline.json?screen_name=twitterapi&count=2
let account = ACAccountStore()
let accountType = account.accountType(
withAccountTypeIdentifier: ACAccountTypeIdentifierTwitter)
account.requestAccessToAccounts(with: accountType,error: NSError!) -> Void in
if success {
let arrayOfAccounts =
account.accounts(with: accountType)
if arrayOfAccounts.count > 0 {
let twitterAccount = arrayOfAccounts.last as! ACAccount
let requestURL = URL(string:
"https://api.twitter.com/1.1/statuses/user_timeline.json")
let parameters = ["screen_name": self.userName!,"count" : "20"]
let postRequest = SLRequest(forServiceType:
SLServiceTypeTwitter,requestMethod: SLRequestMethod.GET,url: requestURL,parameters: parameters)
postRequest.account = twitterAccount
postRequest.perform(
handler: {(responseData: Data!,urlResponse: HTTPURLResponse!,error: NSError!) -> Void in
if error != nil {
Crashlytics.sharedInstance().recordError(error)
}
do {
self.dataSource = try JSONSerialization.jsonObject(with: responseData,options: JSONSerialization.ReadingOptions.mutableLeaves) as! [AnyObject]
if self.dataSource.count != 0 {
DispatchQueue.main.async {
self.tableView.reloadData()
}
}
} catch {
print("catching")
}
})
}
} else {
print("Failed to access account")
}
})
}
解决方法
您应该按如下方式更新代码：
account.requestAccessToAccounts(with: accountType,options: [:]) {
(success: Bool,error: Error?) -> Void in
// blah blah: the rest of the code
}
此版本适用于Xcode 8 GM Swift3(常规版) （编辑：李大同） 【声明】本站内容均来自网络，其相关言论仅代表作者个人观点，不代表本站立场。若无意侵犯到您的权利，请及时与联系站长删除相关内容! |
