表视图单元格事件用nib和storyboard的两种写法总结

一.代码的写法比较
 
ViewController.m

nib写法
#pragma mark - 实现表视图委托方法
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
    NSInteger row = [indexPath row];
   
    CitiesViewController *citiesViewController = [[CitiesViewController alloc] initWithStyle:UITableViewStylePlain];
    NSString *selectName = [self.listData objectAtIndex:row];
    citiesViewController.listData = [self.dictData objectForKey:selectName];
    citiesViewController.title = selectName;
    [self.navigationController pushViewController:citiesViewController animated:YES];

}

storyboard写法
//选择表视图行时候触发
- (void)prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender
{
   
    if([segue.identifier isEqualToString:@"ShowSelectedProvince"])
    {
        CitiesViewController *citiesViewController = segue.destinationViewController;
        NSInteger selectedIndex = [[self.tableView indexPathForSelectedRow] row];
        NSString *selectName = [self.listData objectAtIndex:selectedIndex];
        citiesViewController.listData = [self.dictData objectForKey:selectName];
        citiesViewController.title = selectName;
    }
}

CitiesViewController.m
nib写法
#pragma mark - 实现表视图委托方法
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
    NSInteger row = [indexPath row];
   
    DetailViewController *detailViewController = [[DetailViewController alloc] initWithNibName:@"DetailViewController" bundle:nil];
   
    NSDictionary *dict = [self.listData objectAtIndex:row];
   
    detailViewController.url = [dict objectForKey:@"url"];
    NSString *name = [dict objectForKey:@"name"];
    detailViewController.title = name;
    [self.navigationController pushViewController:detailViewController animated:YES];
   
}
storyboard写法
//选择表视图行时候触发
- (void)prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender
{
     
    if([segue.identifier isEqualToString:@"ShowSelectedCity"])
    {
        DetailViewController *detailViewController = segue.destinationViewController;
       
        NSInteger selectedIndex = [[self.tableView indexPathForSelectedRow] row];
        NSDictionary *dict = [self.listData objectAtIndex:selectedIndex];
       
        detailViewController.url = [dict objectForKey:@"url"];
       
        NSString *name = [dict objectForKey:@"name"];
        detailViewController.title = name;
    }
}
