iOS7 中的表视图

Question

我想知道在ios7中，它是否使用prepareForSegue方法而不是didSelectAtIndexPath方法？

如果是，如何更改可以在 iOS7 中运行的以下代码？

-(void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath{
NSString *tempSqlStatement = @"";
NSString *tempString = @"%";
databaseName = @"TCMdb8.sql";
NSArray *documentPaths = NSSearchPathForDirectoriesInDomains
(NSDocumentDirectory, NSUserDomainMask, YES);
NSString *documentsDir = [documentPaths objectAtIndex:0];
databasePath = [documentsDir stringByAppendingPathComponent:
                databaseName];
if (buttonNum == 0) {
    Function1DetailViewController *function1DetailViewController =
   [[Function1DetailViewController alloc] initWithKey:[listOfItems objectAtIndex:indexPath.row] type:@"1"];
 [self.navigationController pushViewController:function1DetailViewController animated:YES];
}else if (buttonNum != 0){
    if (buttonNum == 1) {
        tableTitle = @"xxxx";
        tempSqlStatement = [NSString stringWithFormat:@"select name from Medicine where stroke ='%@' ORDER BY length(name) ASC", [listOfItems objectAtIndex:indexPath.row]];
         function1SQLStatement = [tempSqlStatement UTF8String];
  }
    [self checkAndCreateDatabase];
    [self readFromDatabase];
    [tableList reloadData];
    buttonNum = 0;
}

这从 iOS2 开始就可用了。您将需要进行一些更改：

if (buttonNum == 0) {
    [self performSegueWithIdentifier:@"Function1Segue" sender:sender];
}

然后实现委托方法：

- (void)prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender
{
    // Make sure your segue name in storyboard is the same as this line
    if ([[segue identifier] isEqualToString:@"Function1Segue"])
    {
        // Get reference to Function1DetailViewController
        //Create new Instance here, and set its properties values
    }
}
