Question

我想让用户填写数字到文本字段，然后我需要将用户值传递给表视图cell.detailTextLabel？任何人都知道如何做到这一点？..

我的代码在这里。

at .h我有

IBOutlet UITextField *numText;
NSString *string;

然后在.m

当按钮单击时，我可以看到字符串处的值。

- (IBAction) scheduleAlarm:(id) sender {
    [eventText resignFirstResponder];
    [numText resignFirstResponder];
    NSCalendar *calendar = [NSCalendar autoupdatingCurrentCalendar];

    // Get the current date
    NSDate *pickerDate = [self.datePicker date];

    // Break the date up into components
    NSDateComponents *dateComponents = [calendar components:( NSYearCalendarUnit | NSMonthCalendarUnit |  NSDayCalendarUnit ) 
                                                   fromDate:pickerDate];
    NSDateComponents *timeComponents = [calendar components:( NSHourCalendarUnit | NSMinuteCalendarUnit | NSSecondCalendarUnit ) 
                                                   fromDate:pickerDate];

    // Set up the fire time
    NSDateComponents *dateComps = [[NSDateComponents alloc] init];
    [dateComps setDay:[dateComponents day]];
    [dateComps setMonth:[dateComponents month]];
    [dateComps setYear:[dateComponents year]];
    [dateComps setHour:[timeComponents hour]];
    // Notification will fire in one minute
    [dateComps setMinute:[timeComponents minute]];
    //[dateComps setSecond:[timeComponents second]];
    NSDate *itemDate = [calendar dateFromComponents:dateComps];
    [dateComps release];

    UILocalNotification *localNotif = [[UILocalNotification alloc] init];
    if (localNotif == nil)
        return;
    localNotif.fireDate = itemDate;
    localNotif.timeZone = [NSTimeZone defaultTimeZone];

    //string =  [numText.text retain];
    // string = [[NSString alloc] initWithString:numText.text];
    string = numText.text;

    test = [[NSMutableArray alloc] init];
    [test addObject:string];

//  self.num = array;
    //[num release];




    NSLog(@"%@",string);
    // Notification details
    localNotif.alertBody = [eventText text];

    // Set the action button
    localNotif.alertAction = @"Send SMS";

    localNotif.soundName = UILocalNotificationDefaultSoundName;
    localNotif.applicationIconBadgeNumber = 1;

    // Specify custom data for the notification
    NSDictionary *infoDict = [NSDictionary dictionaryWithObject:@"someValue" forKey:@"someKey"];
    localNotif.userInfo = infoDict;

    // Schedule the notification
    [[UIApplication sharedApplication] scheduleLocalNotification:localNotif];
    [localNotif release];
    //[numText release];
    //[test release];
    [self.tableview reloadData];

}

当我去UITableView时，我将任何值传递给here.all为null并且我使用UITabBarController第一个选项卡给用户填写数字和event.then在第二个选项卡我需要显示用户填写tableview的值。< / p>

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {

    static NSString *CellIdentifier = @"Cell";

    UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
    if (cell == nil) {
        cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleSubtitle reuseIdentifier:CellIdentifier] autorelease];
    }
   // if (cell == nil) {
    //  cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleValue1 reuseIdentifier:CellIdentifier] autorelease];
    //} 
    // Configure the cell...

    notificationArray = [[UIApplication sharedApplication] scheduledLocalNotifications];
    UILocalNotification *notif = [notificationArray objectAtIndex:indexPath.row];
   //  NSString *enNote = [[NSString alloc] initWithString:string];
   NSString *nomber = [test objectAtIndex:indexPath.row];
    NSLog(@"nomber in get test %@",nomber);


    [cell.textLabel setText:notif.alertBody];

    NSString *abc = [NSString stringWithFormat:@"%@ \n %@",[notif.fireDate description], numText.text];
    NSLog(@"%@",nomber);
    [cell.detailTextLabel  setText:abc];
    cell.detailTextLabel.numberOfLines = 2;

    //cell.detailTextLabel.lineBreakMode = UILineBreakModeWordWrap;




    return cell;
}

创建一个nsmutablearray，并将从textfield获得的值添加到该数组和方法中

(UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath 
{
cell.textlabel.text = [yourarray objectatindex:index];
}

点击你的按键

[yourtable reloaddata];
