Tableview - NSMutableDictionary - currow 获取整数值？ iPhone

Question

如何将 ID 的值转换为整数。见下文：

- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath {

    NSMutableDictionary *curRow = [myData objectAtIndex:indexPath.row];

    NSLog(@"Cell Click  %@ %@  -  %@",[curRow objectForKey:@"Name"], [curRow objectForKey:@"ID"], [curRow objectForKey:@"DOB"]);

    UserID= [curRow [objectForKey:@"ID" intValue]  ;  <<<< This doesnt work?

Answer 1

如果 ID 在字典中，您可以使用字符串

UserID = [[curRow objectForKey:@"ID"] intValue];

Answer 2

你的语法有错误。

UserID= [curRow [objectForKey:@"ID" intValue]  ;  <<<< This doesnt work?

使用下面

UserID= [[curRow objectForKey:@"ID"] intValue]  ;  <<<< This will work?
