将Appirater添加到我的iOS项目后,当我编译时,我收到错误:

Undefined symbols for architecture i386:
  "_OBJC_CLASS_$_Appirater", referenced from:
      objc-class-ref in AppDelegate.o
ld: symbol(s) not found for architecture i386
clang: error: linker command failed with exit code 1 (use -v to see invocation)

在互联网上搜索和搜索后,找不到任何解决方案.

我的项目和目标都设置为:

我该怎么做？

我在我的项目中使用了几个'.o'文件,在编译时显示以下错误,

error:linker command failed with exit code 1 (use -v to see invocation)

我在下面发布了错误日志

我曾在谷歌日历工作过.现在我从这个链接下载示例代码:

"http://code.google.com/p/iphone-gcal/". 

但是在这段代码中,缺少一些Gdata代码.所以我已经实现了该代码,但我也得到了以下错误.请一些人帮我解决这个错误.

我想逐行阅读文本文件,并使用此处显示的示例在iOS屏幕上显示它.

制作textView.text可选项是我能够readDataFromFile运行的唯一方式.当我单击load该函数运行但总是返回nil.我认为这意味着找不到文件.

出于测试目的,我在Xcode中创建了文本文件.我也尝试将它保存在桌面和项目文件夹中.无论哪种方式,它都可以从项目导航器中读取.我还尝试使用TextEdit创建文件,因为应用程序最终需要读取在Xcode外部创建的文本文件.

如果有人可以解释为什么永远不会找到文本文件,我是否感激不已,为了让项目找到它还是需要做些什么,或者nil由于我的方式而导致读取函数由于其他原因而返回实施了它.谢谢.

编辑(2)

感谢您的反馈.作为回应,我做了四个小的代码更改,允许将文本文件内容写入textView.更改包括:从文件名中删除文件扩展名,添加文件名数组,String而不是String?从代码中返回readDataFromFile和重写UITextView.这解决了我所知道的问题.

这是修改后的代码

import UIKit

class ViewController: UIViewController {

var textView = UITextView()
var arrayOfStrings: [String]?
var fileNameWithExtension               = "textFile.txt"
let arrayOfFileNames                    = ["textFile1.txt", "textFile2.txt", "textFile3.txt", "textFile4.txt", "textFile5.txt"]

var fileName                            = String()

override func viewDidLoad() {
    super.viewDidLoad()

    //    remove comment in the next statement to test files named in ArrayOfFileNames    
    //    fileNameWithExtension               = …
