- [__ NSCFArray objectForKey：]：无法识别的选择器发送到实例0x11c824e0

Question

I face this error, Please help me for this and here is my code:

if(![[tmparr objectForKey:@"error"] isEqualToString:@"No data found"]){
resultArray = [NSArray arrayWithArray:[NSJSONSerialization JSONObjectWithData:data options:kNilOptions error:nil]];}

Answer 1

问题是tmparr是NSArray类型的变量，但我猜你在这行中将它视为NSDictionary ：

[tmparr objectForKey:@"error"];

Answer 2

I solve this issue thanks to all

if( [tmparr isKindOfClass:[NSDictionary class]] && ![[tmparr objectForKey:@"error"] isEqualToString:@"No data found"]){

                 resultArray = [NSArray arrayWithArray:[NSJSONSerialization JSONObjectWithData:data options:kNilOptions error:nil]];
         }
