【问题描述】：

我有下面的数组

(
    (
        "id:19",
        "name:Virgin Club House Heathrow",
        "address:Heathrow Airport, 234 Bath Road, Hayes, Middlesex",
        "postcode:UB3 5AP",
        "latitude:51.48127",
        "longitude:-0.448696"
    ),
        (
        "id:20",
        "name:Le Bilboquet",
        "address:20 E 60th St, New York, United States",
        "postcode:NY 10022",
        "latitude:40.764072",
        "longitude:-73.970834"
    )
)

我通过使用

来列举

[venuesArray enumerateObjectsUsingBlock:^(NSDictionary* obj, NSUInteger index, BOOL *stop)
{
     NSString* tmpStr;
     tmpStr = [obj objectForKey:@"id"];
}];

但是我收到此错误 -[__NSCFArray objectForKey:]: unrecognized selector sent to instance 0x7ff26866a690.

【解决方案1】：

就像你说的，你有一个数组。即使您的块正在调用它正在获取NSDictionary 的对象，它也会被赋予一个数组。使用NSLog打印出obj的数据类型和内容来调试。
