这是我的错误:
由于未捕获的异常"NSInternalConsistencyException"而终止应用程序,原因:"无效更新:节0中的行数无效。"。更新后的现有节中包含的行数(2(必须等于更新前该节中所包含的行数来(2(,加上或减去从该节插入或删除的行数,(0插入,1删除(加上或减移入或移出该节的行数。">
我知道这意味着什么,但我在代码中找不到我的错误。我知道我只能使用NSMutableArry。不是一个正常的NSArray。这就是我认为的要点。。。
在我的h.文件中:NSMutableArray*notifArray,IBOutlet UITableView*myTable;
代码:
- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section {
// Return the number of rows in the section.
return [[[UIApplication sharedApplication] scheduledLocalNotifications] count];
}
代码:
// 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:UITableViewCellStyleSubtitle reuseIdentifier:CellIdentifier] autorelease];
}
// Configure the cell...
NSArray *_notifArray = [[UIApplication sharedApplication] scheduledLocalNotifications];
UILocalNotification *notif = [_notifArray objectAtIndex:indexPath.row];
<...>
代码:
- (void)tableView:(UITableView *)tableView commitEditingStyle:(UITableViewCellEditingStyle)editingStyle forRowAtIndexPath:(NSIndexPath *)indexPath {
// If row is deleted, remove it from the list.
if (editingStyle == UITableViewCellEditingStyleDelete) {
[notifArray removeObjectAtIndex:indexPath.row];
[self.myTable deleteRowsAtIndexPaths:[NSArray arrayWithObject:indexPath] withRowAnimation:UITableViewRowAnimationFade];
[myTable reloadData];
}
}
代码:
- (IBAction) scheduleAlarm:(id) sender {
[eventText 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];
localNotification = [[UILocalNotification alloc] init];
if (localNotification == nil)
return;
localNotification.fireDate = itemDate;
localNotification.timeZone = [NSTimeZone defaultTimeZone];
// Notification details
localNotification.alertBody = [eventText text];
// Set the action button
localNotification.alertAction = @"View";
localNotification.soundName = UILocalNotificationDefaultSoundName;
localNotification.applicationIconBadgeNumber = 1;
// Specify custom data for the notification
NSDictionary *infoDict = [NSDictionary dictionaryWithObject:@"someValue" forKey:@"someKey"];
localNotification.userInfo = infoDict;
// Schedule the notification
[[UIApplication sharedApplication] scheduleLocalNotification:localNotification];
[localNotification release];
[self.myTable reloadData];
}
如果我将这一行更改为NSMutabelArray,我也会出现错误。使用类型为"NSArray*"的表达式初始化"NSMUtableArray"的指针类型不兼容
---> NSArray *_notifArray = [[UIApplication sharedApplication] scheduledLocalNotifications];
那么,我该怎么做,才能删除包含localNotification的行呢?
非常感谢
我认为我的问题最初是一个错误的代码;-(第二次我忘记了连续显示的通知是两件事!因此,我必须先删除Notification,然后再删除表中的Row View;-(
这是我的代码-请放心;-(
- (void)tableView:(UITableView *)tableView commitEditingStyle:(UITableViewCellEditingStyle)editingStyle forRowAtIndexPath:(NSIndexPath *)indexPath {
// If row is deleted, remove it from the list.
if (editingStyle == UITableViewCellEditingStyleDelete)
{
// DELETE theNotification defined in (UITableViewCell *)tableView:{}
[[UIApplication sharedApplication] cancelLocalNotification:notifcation];
// DELETE theRow
[notificationsArray removeObjectAtIndex:indexPath.row];
[tableView deleteRowsAtIndexPaths:[NSMutableArray arrayWithObject:indexPath] withRowAnimation:UITableViewRowAnimationLeft];
[tableView reloadData];
}
}
是的,我很高兴;-(无论如何,我真的是个新手因此,如果有人有更好的方法,请随时纠正我:-(
关于初始化,您可以创建这样的可变数组:
NSMutableArray *_notifArray = [NSMutableArray arrayWithArray:[[UIApplication sharedApplication] scheduledLocalNotifications]];
你可能也需要保留它。
关于行删除,我想知道调用reloadData的情况。我认为没有必要,因为前一行DeleteRows。。。导致表视图的更新,我甚至想知道这是否可能是您的消息的原因。当然,它是在DeleteRows之后调用的,但我们无法真正知道这是如何排序的,如果在DeleteRow完成之前重载查询numberOfRows,那么它可能会导致您的消息。
希望这能有所帮助。
