关于表视图单元格indexpath.row

Question

I am getting error when i am assigning value to the cell like

profileJson = dicData[@"profile"][0];

cell.userName.text = [[profileJson objectForKey:@"First_Name"] objectAtIndex:indexPath.row];

Error: [__NSCFString objectAtIndex:]: unrecognized selector sent to instance 0x7fe5915d7180

If i write this statement

cell.userName.text = [profileJson objectForKey:@"First_Name"];

The last value is getting assigned. If the count is 3 then output looks like this:

Teja

Teja

Teja

For every cell.

Answer 1

You seem to be mismatching your code to interrogate the data structure unpacked from the JSON, you haven't included it, but it would seem like you need:

profileJson = dicData[@"profile"][indexPath.row];

cell.userName.text = [profileJson objectForKey:@"First_Name"];

so you're indexing into the profiles array based on your table index, rather than always taking the first one, and then extracting the first name variable (where you were previously confused about arrays and strings).

Answer 2

This in your "cellForRowAtIndexPath:" method

NSDictionary *profileJson = dicData[@"profile"][indexPath.row];

NSString *userNameString = [profileJson objectForKey:@"First_Name"];

cell.userName.text = userNameString;
