我对 ios 开发非常陌生，我正在尝试从 to 添加一些值NSMutableDictionary，NSMutableArray当我运行代码时出现此错误
2012-05-29 14:09:34.913 iShop[7464:f803]-[__NSCFArray objectForKey:]: 无法识别的选择器发送到实例 0x6e423d0 2012-05-29 14:09:34.915 iShop[7464:f803] * 由于应用程序终止未捕获的异常'NSInvalidArgumentException'，原因是： ' - [__ NSCFArray objectForKey：]：无法识别的选择发送到实例0x6e423d0' *第一掷调用堆栈：（0x13cb022 0x155ccd6 0x13cccbd 0x1331ed0 0x1331cb2 0x2bb7 0x13cce42 0x93b9df 0x139f94f 0x1302b43 0x1302424 0x1301d84 0x1301c9b 0x12b47d8 0x12b488a 0x15626 0x28bd 0x2825）终止称为抛出异常（lldb）
下面是我的代码：
-(void) getData:(NSData *) response {
NSError *error;
NSMutableDictionary *json = [NSJSONSerialization JSONObjectWithData:response options:kNilOptions error:&error];
//NSLog(@"%@", json);
jsonArray = [[NSMutableArray alloc] init];
jsonArray = [json objectForKey:@"Name"];
NSLog(@"%@", jsonArray);
}
- (void)viewDidLoad {
[super viewDidLoad];
jsonURL = [NSURL URLWithString:@"http://localhost:8888/read_product_list.php"];
dispatch_async(BgQueue, ^{
NSData* data = [NSData dataWithContentsOfURL:jsonURL];
[self performSelectorOnMainThread:@selector(getData:)
withObject:data waitUntilDone:YES];
});
}
