ios - 如何将整数值解析为 Json iOS？

Question

我通过了 NSstring 它正在将数据正确地传送到 uitableview 但是当我解析整数值时它显示异常 Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: -[__NSCFNumber isEqualToString:]: unrecognized selector sent to实例 0x744e9d0这是我的代码

(void)fetchedData:(NSData *)responseData {  
//parse out the json data  
NSError* error;  
NSDictionary* json = [NSJSONSerialization  
JSONObjectWithData:responseData options:kNilOptions error:&error];  
  NSArray * values=[json objectForKey:@"loans"];  


 NSLog(@"Array: %@",values);

for (NSDictionary *file in values)
        {
            NSNumber *fileTitle=[file objectForKey:@"id"];
            // NSString *fileTitle = [file objectForKey:@"sector"];
            [titles addObject: fileTitle];
        }
[self.mainTableView reloadData];

 }

Answer 1

您正在将字符串值分配给 NSNumber 类型。尝试使用这个

NSString *fileTitle=[file objectForKey:@"id"];

[titles addObject: fileTitle];

并使用字符串值。
