我有一个充满引号的“factsArray”。 randomFact()函数从“factsArray”中随机选择一个引号，返回值显示在我的视图控制器上的标签中。
我将视图控制器上显示的引号保存到NSUserDefaults。在quoteIndexArray()函数内部，我试图将此字符串保存在NSUserDefaults中，并使用for in循环将其与我的“factsArray”中的字符串匹配...然后返回索引那个价值。
对于那么容易的事情有严重的麻烦。有人请引导我进入光明。提前谢谢！

简单到（直接比较）：
for (index, value) in enumerate(factsArray) {
if(i == value) {
println("Item \(index): \(value)")
}
}
答案 1 :(得分：1)
我同意上述评论，即更容易存储<em>索引 用户默认值中的字符串。
如果不可能：
NSArray有一个indexOfObject()方法，它返回对象的第一个索引
在数组中：
let index = factsArray.indexOfObject(i)
if index != NSNotFound {
println(index)
} else {
println("not found")
}
或者，您可以将NSArray桥接到Swift [String]数组
并使用find()函数：
if let index = find(factsArray as [String], i) {
println(index)
} else {
println("not found")
}
答案 2 :(得分：0)
您的条件似乎没有意义。当您将字符串与NSArray类型的对象进行比较时，if i as NSString == factsArray as NSArray应始终评估为false。如果您改为检查if i as NSString == value，那么您将检查存储在数组中的值是否相等。
此外，我不知道你在NSUserDefaults上写下你的报价的地方（获得批准，或许你在其他地方做过这样的工作）。
