在UITableView的detailedTextLabel中连接两个字符串

Question

嗨，我有这行代码。

cell.detailTextLabel.text = [[self->jsonArray objectAtIndex:indexPath.row] objectForKey:@"city"];

我想使用两个objectForKeys。我有一个“城市”和“状态”键我希望他们在那个详细的TextLabel中放在一起。我该怎么做？

Answer 1

cell.detailTextLabel.text = [NSString stringWithFormat:@"%@, %@",
                             [[self->jsonArray objectAtIndex:indexPath.row] objectForKey:@"city"], 
                             [[self->jsonArray objectAtIndex:indexPath.row] objectForKey:@"state"]];

Answer 2

您可以这样做：

NSString *city = [[self->jsonArray objectAtIndex:indexPath.row] objectForKey:@"city"];
NSString *state = [[self->jsonArray objectAtIndex:indexPath.row] objectForKey:@"state"];
NSString *combined = [NSString stringWithFormat:@"%@ (%@)", city, state];
cell.detailTextLabel.text = combined;

Answer 3

试试这个：

cell.detailTextLabel.text = [NSString stringWithFormat:@"%@ %@",[[self->jsonArray objectAtIndex:indexPath.row] objectForKey:@"city"],[[self->jsonArray objectAtIndex:indexPath.row] objectForKey:@"state"]];

Answer 4

NSString *city = [[self->jsonArray objectAtIndex:indexPath.row] objectForKey:@"city"];
NSString *state =[[self->jsonArray objectAtIndex:indexPath.row] objectForKey:@"state"];
cell.detailTextLabel.text = [NSString stringWithFormat:@"city is : %@  state is: %@", city, state];

Answer 5

你试过这样的事吗？

NSString *city = [[self->jsonArray objectAtIndex:indexPath.row] objectForKey:@"city"];
NSString *state = [[self->jsonArray objectAtIndex:indexPath.row] objectForKey:@"state"];
cell.detailTextLabel.text = [[NSString alloc]initWithFormat:@"%@ %@",city,state];
