按字母顺序对数组排序并在表视图中显示数组值 [英] Sorting array in alphabetic order and displaying array values in table view

问题描述

我必须打印 NSMutableArray * lstAirports;

我的对象数组将在表视图单元格中打印所有记录

my array of object it print all record in table view cell

我想按字母顺序对单元格值进行排序.

I want to sort my cell value in alphabetical order.

该怎么做，请帮助一些未按字母顺序显示的代码

how to do that please some help this code not given me display in alphabetical order

这是我的控制器类代码

- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section {
    // Return the number of rows in the section.
    return app.lstAirports.count;
}


// Customize the appearance of table view cells.
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {

    static NSString *CellIdentifier = @"Cell";

    UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
    if (cell == nil) {
        cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleValue1 reuseIdentifier:CellIdentifier] autorelease];
    }
    airport *a=(airport*)[app.lstAirports objectAtIndex:indexPath.row];
    NSLog(@"str:%@",a);
    cell.textLabel.text =a.Name;
    cell.detailTextLabel.text=a.Code;
    // Configure the cell...

    return cell;
}

推荐答案

您可以轻松地对 NSMutableArray 进行排序:

You can easily sort a NSMutableArray:

NSSortDescriptor *nameSort = [NSSortDescriptor sortDescriptorWithKey:@"Name" ascending:YES];
[lstAirports sortUsingDescriptors:[NSArray arrayWithObject:nameSort]];
