Iphone 如何理解web服务应答中的字符串或数组

我从web服务获取数组值。此数组是1个或多个1元素数组。如果tempArra是一维数组，然后如果我想将数组中的数据传输到另一个数组（garbageDatesFor01），则会得到错误

EDIT: returning to the web service responses in 2 ways

RESPONSE 1

(
    (
    "2011-08-03",
    "2011-08-17"
    )
)

OR

RESPONSE 2
2011-08-04

NSArray *garbageDatesFor01=[[NSArray alloc] initWithArray:tempArr];

重要的一点是：

2011-08-26 18:43:35.689 TwenteMilieu[1846:207] -[NSCFString count]: unrecognized selector sent to instance 0x990d8f0

这意味着您正在对字符串调用

count

。您认为是数组的对象实际上是字符串

通过查看代码，

tempArr

可以是数组或字符串。试试这个：

if ([tempArr isKindOfClass:[NSArray class]])
{
    // Handle array case
}
else if ([tempArr isKindOfClass:[NSString class]])
{
    // Handle string case
}

---

将

tempArr

的名称改为其他名称可能是个好主意，例如

tempResponse

或类似名称。

我更新为问题。我并没有为这个问题的解决帮梅更新到问题。我不知道这个问题的解决方法对我有什么帮助
