我有一個帶有切換開關輔助視圖的桌面視圖。我指定了該部分和行,並且難以確定哪一行被切換。我使用toggleSwitch.tag來抓取indexRow,但是因爲我的indexRow是indexPath.section的一部分,所以我不知道如何判斷我切換了哪一行。如何判斷哪些行切換開關已更改

下面是代碼:

- (UITableViewCell *)tableAlert:(SBTableAlert *)tableAlert cellForRowAtIndexPath:(NSIndexPath *)indexPath { 
UITableViewCell *cell; 

Category *cat = [allCategories objectAtIndex:indexPath.section]; 
Subject *sub = [cat.subjects objectAtIndex:indexPath.row]; 

cell = [[[SBTableAlertCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:nil] autorelease]; 
UISwitch *toggleSwitch = [[UISwitch alloc] init]; 
cell.accessoryView = [[UIView alloc] initWithFrame:toggleSwitch.frame]; 
[cell.accessoryView addSubview:toggleSwitch]; 

cell.textLabel.text =sub.title; 
cell.detailTextLabel.text = sub.category_title; 

if (sub.active==1){ 
    [toggleSwitch setOn:YES]; 
} else { 
    [toggleSwitch setOn:NO]; 
} 

toggleSwitch.tag = indexPath.row; 

[toggleSwitch addTarget:self action:@selector(viewButtonPushed:) forControlEvents:UIControlEventValueChanged]; 
[toggleSwitch release]; 

return cell; 

} 


- (void)viewButtonPushed:(id)sender { 
UIButton *button = (UIButton *)sender;  
UITableViewCell *cell = button.superview; // adjust according to your UITableViewCell-subclass' view hierarchy 
NSIndexPath *indexPath = [self.tableView indexPathForCell:cell]; 

Category *cat = [allCategories objectAtIndex:indexPath.section]; 
Subject *sub = [cat.subjects objectAtIndex:indexPath.row]; 

selectedSubject = sub; 

UISwitch* switchControl = sender; 
NSLog(@"The switch is %@", switchControl.on ? @"ON" : @"OFF"); 

if(switchControl.on){ 
    [sub setActive:1]; 
    NSLog(@"%@ is being set to ACTIVE", selectedSubject.title); 
}else{ 
    [sub setActive:0]; 
    NSLog(@"%@ is being set to INACTIVE", selectedSubject.title); 
} 

[sub setIsDirty:YES]; 

[cat.subjects replaceObjectAtIndex:indexPath.row withObject:sub]; 

[sub autorelease]; 
[cat autorelease]; 

} 

這裏是我的didSelectRowAtIndexPath方法。我需要在此處提及toggleSwitch嗎?

- (void)tableAlert:(SBTableAlert *)tableAlert didSelectRowAtIndexPath:(NSIndexPath *)indexPath { 

Category *cat = [allCategories objectAtIndex:indexPath.section]; 
Subject *sub = [cat.subjects objectAtIndex:indexPath.row]; 

selectedSubject = sub; 
NSLog(@"selectedSubject = %@", selectedSubject.title); 


if (tableAlert.type == SBTableAlertTypeMultipleSelct) { 
    UITableViewCell *cell = [tableAlert.tableView cellForRowAtIndexPath:indexPath]; 
    if (cell.accessoryType == UITableViewCellAccessoryNone) 
     [cell setAccessoryType:UITableViewCellAccessoryCheckmark]; 
    else 
     [cell setAccessoryType:UITableViewCellAccessoryNone]; 

    [tableAlert.tableView deselectRowAtIndexPath:indexPath animated:YES]; 
} 

}

你知道你確實有,如果你在一個plist中或類似保存它寫入到磁盤的變化。僅僅因爲你改變了數組並不會改變文件本身。 – 2012-02-24 21:06:44

是的,我稍後再做。在進一步的調試中,我發現我的問題不在保存到數組中,而是在確定哪一行切換切換。 – jroyce 2012-02-24 21:37:23

我發現,你需要去該項目的單元格中的上海華盈的上海華盈(假設按鈕或控制權落細胞的根),以得到的指針細胞。

試試這個:

UITableViewCell *cell = button.superview.superview; 

,看看效果更好。看看我的博客文章在此瞭解更多信息:

Two superviews are better than one

這很奇怪......以前從未見過。 – 2012-02-24 21:12:28
