Question

I’ m creating a custom UITableViewCell view. I have a method for UITableViewCell and I have created UILabel memberLabel programmatically:

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath  {

static NSString * const cellIdentifier = @"cellMemberId";

CPNMemberCell *cell = (CPNMemberCell *) [tableView dequeueReusableCellWithIdentifier:cellIdentifier];

if (!cell) {

    [[NSBundle mainBundle] loadNibNamed:@"TeamCell" owner:self options:nil];
    cell = baseCell;
}

memberLabel = [[UILabel alloc] initWithFrame:CGRectMake(32, 19, 183, 27)];
[cell addSubview:memberLabel];

NSString * const test = @"test input";
memberLabel.text = test;

  return cell;
}

So this code works quite well. But when I change test string value to string containing JSON response in MutableDictionary, all fails. I specially output that string to console log in order to be sure it is not empty or whatever. And I have an except during assigning
that string to UILabel:

NSString * const test = [members valueForKey:@"modelId"];
NSLog(@"Output: %@", test);
memberLabel.text = test;

I don’t understand what’s wrong: response correctly prints to the console, UILabel correctly displays text strings as in the first code block, but when I try to display string with that response I have a SIGABRT exception in the main.

Check what is the data type of test variable. Use:

NSLog(@"data type = %@", [[test class] description]);

Is it printing data type = NSString? If not, that is the issue.

Also try this,

NSString* test = [ _members valueForKey:@"modelId"];
NSLog(@"Testing response in the console: %@", test);
if ([test isKindOfClass:[NSString class]]) {
  memberLabel.text = test;
} else {
  NSLog(@"test is not a string"); 
}
