我正试图在UITableview中显示我的记录。我可以得到json数据。问题出现在UITableViewCell。
-(void)getData {
AFHTTPRequestOperationManager *manager = [AFHTTPRequestOperationManager manager];
manager.responseSerializer = [AFHTTPResponseSerializer serializer];
NSDateFormatter *dateFormatter = [[NSDateFormatter alloc] init];
[dateFormatter setDateFormat:@"yyyy-MM-dd HH:mm:ss"];
NSString *dateString;
dateString = [dateFormatter stringFromDate:[NSDate date]];
NSDictionary *params = @{@"tarih":dateString,@"email":@"email@email.com",@"token":@"token",@"id":@"11"};
NSString *url = [NSString stringWithFormat:@"http://crm.mywebsite.com/api/sync.php"];
[manager POST:url parameters:params success:^(AFHTTPRequestOperation * _Nonnull operation, id _Nonnull responseObject) {
NSDictionary *dataDictionary = [NSJSONSerialization JSONObjectWithData:responseObject options:0 error:&testerror];
NSLog(@"%@",dataDictionary);
_customerList = [NSMutableArray array];
NSArray *customerArray = [dataDictionary valueForKey:@"kart"];
for (NSDictionary *customerDictionary in customerArray) {
NKart *card = [NKart taskWithTitle:[customerDictionary valueForKey:@"adi"]];
card.adres = [customerDictionary valueForKey:@"adres"];
NSLog(@"%@",card.adres);
[self.customerList addObject:card];
[self.tableView reloadData];
}
} failure:^(AFHTTPRequestOperation * _Nonnull operation, NSError * _Nonnull error) {
NSLog(@"Error: %@",error);
}];
cellForRowAtIndexPath方法。
NKart *card = [_customerList objectAtIndex:indexPath.row];
cell.textLabel.text= card.adi;
当我尝试在tableview中显示它时，我收到了这个错误。

好吧，日志说明了一切 - 您认为属于NSString类型的对象实际上是NSArray。由于NSArray没有响应任何名为isEqualToString的方法，因此崩溃了！
以下是可能发生的事情：
查看您的NKart型号设置。虽然您已将adi声明为NSString，但您实际上是将NSArray输入到NSString。显然你得到一个NSArray，当你将这个对象设置为你的标签的文本属性时，幕后会发生一些事情，询问当前的字符串属性是否等于你正在尝试的属性设置。这导致崩溃!!!
答案 1 :(得分：0)
您在这里分配NSArray而不是NSString：
NKart *card = [NKart taskWithTitle:[customerDictionary valueForKey:@"adi"]];
你需要仔细检查传入的JSON，但它肯定是一个数组，而不是一个字符串。
你可能想要：
NSArray *adi = customerDictionary[@"adi"];
if ([adi count] > 0) {
NKart *card = [NKart taskWithTitle:adi[0]];
...
}
虽然我不知道完全需要什么;只有你这样做。
答案 2 :(得分：0)
isEqualToString 方法保留在 NSString 类中。但 NSArray 类不存在此方法。
提供
的价值NSLog(@"%@",dataDictionary);
快速解决您的问题。
第二次尝试：您的代码仍然是一些不必要的代码。
NSDictionary *dataDictionary = [NSJSONSerialization JSONObjectWithData:responseObject options:0 error:&testerror];
NSLog(@"%@",dataDictionary);
_customerList = [NSMutableArray array];
//NSArray *customerArray = [_customerList addObject:[dataDictionary valueForKey:@"kart"]];
//for (NSDictionary *customerDictionary in customerArray) {
NKart *card = [NKart taskWithTitle:[customerDictionary valueForKey:@"adi"]];
card.adres = [customerDictionary valueForKey:@"adres"];
NSLog(@"%@",card.adres);
[self.customerList addObject:card];
[self.tableView reloadData];
//}
