解析SDK 1.7.1在Xcode 6.3中不起作用

问题描述

我的代码在Xcode 6.2中运行良好.在更新到Xcode 6.3之后，我遇到了一些Nullabilty错误.

My code worked fine in Xcode 6.2. After the update to Xcode 6.3 I had some Nullabilty Errors.

下载Parse SDK 1.7.1之后，我可以解决这些错误.因此，我在项目中删除了旧的Parse框架文件，然后将新文件粘贴到该文件中.另外，我将代码转换为最新的Swift语法编辑/转换/最新的Swift语法".现在，我对Nullabilty错误没有任何疑问，但还有其他几个问题.在我的项目中，我有一个简单的Tableviewcontroller，其中包含以下代码:

I could solve these errors after I downloaded the Parse SDK 1.7.1. So I deleted the old Parse framework files in my project and pasted the new ones into it. Additional I convert my code to the latest swift syntax "Edit/Convert/latest swift syntax". Now I haven't problems with Nullabilty Errors but several others.In my project I have a simple Tableviewcontroller with the following code:

import UIKit

class HaendlerTableViewController: PFQueryTableViewController {
// Initialise the PFQueryTable tableview
override init!(style: UITableViewStyle, className: String!) {  //1. Falialbe initialize init/style:className:)' cannot override a non-failable initializer
    super.init(style: style, className: className)
}

required init(coder aDecoder: NSCoder) {
    super.init(coder: aDecoder)

    // Configure the PFQueryTableView
    self.parseClassName = "Haendler"
    self.textKey = "name"
    self.pullToRefreshEnabled = true
    self.paginationEnabled = false
}

// Define the query that will provide the data for the table view
override func queryForTable() -> PFQuery! {  //2. Ovverriding method with selector queryForTable has incompatitble typ () -> PFQuery
    var query = PFQuery(className: "Haendler")
    query.orderByAscending("name")
    return query
}

override func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath, object: PFObject) -> PFTableViewCell { //3. Ovverriding method with selector 'tableView:cellForRowAtindexPath:object:' has incompatible type '(UITableView, NSIndexPath, PFObject) -> PFTableViewCell

    var cell = tableView.dequeueReusableCellWithIdentifier("HaendlerCell") as! HaendlerCell!
    if cell == nil {
        cell = HaendlerCell(style: UITableViewCellStyle.Default, reuseIdentifier: "Cell")
    }

    // Extract values from the PFObject to display in the table cell
    cell.haendlerName.text = object["name"] as! String!

    var thumbnail = object["logo"] as! PFFile
    var initialThumbnail = UIImage(named: "haendler")
    cell.haendlerBild.image = initialThumbnail
    cell.haendlerBild.file = thumbnail
    cell.haendlerBild.loadInBackground()

    return cell
}


override func prepareForSegue(segue: UIStoryboardSegue, sender: AnyObject?) {


    var detailScene = segue.destinationViewController as! HaendlerDetailViewController

    // Pass the selected object to the destination view controller.
    if let indexPath = self.tableView.indexPathForSelectedRow() {
        let row = Int(indexPath.row)
        detailScene.currentObject = objects[row] as? PFObject //4. Could not find an overload for 'subscript' that accepts the supplied agruments
    }
}

}

我在代码右侧的注释中写了错误， 以下.

I wrote the errors in a comment on the right side of the code and below.

1. Falialbe初始化init/style:className :)'无法覆盖非失败的初始化器
2. 带有选择器queryForTable的遍历方法的类型()-> PFQuery不兼容
3. 具有选择器'tableView:cellForRowAtindexPath:object:'的遍历方法具有不兼容的类型'(UITableView，NSIndexPath，PFObject)-> PFTableViewCell
4. 找不到接受提供的agruments的'subscript'超载

当我从Parse Quickstart中创建一个新的Swift项目并添加一个Tableviewcontroller时，我遇到了相同的错误.在我的旧项目中，我删除了一个Objective-C桥接标头，因为我有机会直接在我的Swift项目中添加Parse SDK 1.7.1，所以我删除了它.

I have the same errors when I make a new Swift project from the Parse Quickstart and add one Tableviewcontroller. In my old project was an objective-C bridging header which one I deleted because I had the oppurtunity to add the Parse SDK 1.7.1 directly in my Swift project.

现在我需要帮助，因为我看不到要更改的内容.

Now I need help because I don't see what I have to change..

PS:对不起，德语和英语代码的混合，一旦项目再次运行，我会对其进行调整

PS: Sorry for the mix of German and English code I'll adjust it once the project is running again

推荐答案

存在相同的问题.

要解决第一个初始化问题，请删除！"在'override init'之后.应该看起来像这样:

To solve the first initialise issue remove the '!' after 'override init'. Should look like this:

// Initialise the PFQueryTable tableview
override init(style: UITableViewStyle, className: String!) {  //1. Falialbe initialize init/style:className:)' cannot override a non-failable initializer
    super.init(style: style, className: className)
}

对"PFQuery"之后的第二个错误执行相同的操作

Do the same for the 2nd error after 'PFQuery'

override func queryForTable() -> PFQuery {

希望它会有所帮助.由于通常需要对最新更新的拆包元素进行修订以解决可能的错误.

Hope its helpful. Since the latest update unwrapping elements usually needs to be revised for possible errors.
