【问题描述】:
我有一个表格视图,其中每个单元格都有一个 UISwitch,当我选择一个单元格时,我将能够切换 UISwitch,当我选择表格视图中的下一个单元格时,我不应该能够切换它甚至如果我想切换它,之前选择的切换应该用 UIAlertView 关闭,所以基本上应该只允许一个 UITableViewCell 切换。
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
static NSString *cellIdentifier=@"cellIdentifier";
PPtableCell *cell=(PPtableCell*)[tableView dequeueReusableCellWithIdentifier:cellIdentifier];
if (cell==nil)
{
cell=[[PPtableCell alloc]initWithStyle:UITableViewCellStyleDefault reuseIdentifier:cellIdentifier];
}
cell.remedyImage.image=[[remedyArray objectAtIndex:indexPath.row]objectForKey:@"RemedyImageDic"];
cell.remedyTextLabel.text=[[remedyArray objectAtIndex:indexPath.row]objectForKey:@"RemedyTxtDic"];
cell.remedyLabel.text=[[remedyArray objectAtIndex:indexPath.row]objectForKey:@"RemedyName"];
cell.remedyID=[[[remedyArray objectAtIndex:indexPath.row]objectForKey:@"RemedyID"]intValue];
cell.frequency = [[[remedyArray objectAtIndex:indexPath.row]objectForKey:@"RemedyFrequency"]intValue];
cell.symptomIDNo =[[[remedyArray objectAtIndex:indexPath.row]objectForKey:@"SymptomID"]intValue];
// cell.textLabel.text = [[notify objectAtIndex:indexPath.row] objectForKey:@"notifyData"];
// Specific Background Image Depending upon the Row
if (indexPath.row==0)
{
cell.backgroundCellImage.image=[UIImage imageNamed:@"top-cell.png"];
}
else if (indexPath.row==remedyArray.count-1)
{
cell.backgroundCellImage.image=[UIImage imageNamed:@"bottom-cell.png"];
}
else
{
cell.backgroundCellImage.image=[UIImage imageNamed:@"middle-cell.png"];
}
if ([indexPath isEqual:remedySelectedIndexPath])
{
cell.isZoomedIn = YES;
}
else
{
cell.isZoomedIn = NO;
}
return cell;
}
}
-(void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
if(tableView==remedyTableView)
{
PPtableCell *cell = nil;
cell=( PPtableCell*)[tableView cellForRowAtIndexPath:indexPath];
cell.selectionStyle=UITableViewCellSelectionStyleNone;
CGSize maximumLabelSize=CGSizeMake(320.0,100.0);
CGSize expectedLabelSize=[cell.remedyTextLabel.text sizeWithFont:cell.remedyTextLabel.font constrainedToSize:maximumLabelSize
lineBreakMode:cell.remedyTextLabel.lineBreakMode];
if (expectedLabelSize.height > 17 || expectedLabelSize.width > 260.0)
{
if ([indexPath isEqual:remedySelectedIndexPath])
{
remedySelectedIndexPath = nil;
[remedyTableView reloadRowsAtIndexPaths:[NSArray arrayWithObject:indexPath] withRowAnimation:UITableViewRowAnimationNone];
}
else
{
oldSelectedIndexPath=remedySelectedIndexPath;
remedySelectedIndexPath=indexPath;
if (oldSelectedIndexPath==nil)
{
[remedyTableView reloadRowsAtIndexPaths:[NSArray arrayWithObject:remedySelectedIndexPath] withRowAnimation:UITableViewRowAnimationNone];
}
else
{
[remedyTableView reloadRowsAtIndexPaths:[NSArray arrayWithObjects:oldSelectedIndexPath,remedySelectedIndexPath,nil] withRowAnimation:UITableViewRowAnimationNone];
}
}
}
}
}
这是处理 UISwitches 的代码:
(IBAction)notification:(id)sender {
if (sender == notifyMe) {
if(notifyMe.isOn == YES) {
toggle = YES;
NSUserDefaults* defaults = [NSUserDefaults standardUserDefaults];
[defaults setBool:notifyMe.on forKey:@"switchValueKey"];
[defaults synchronize];
NSLog(@"Notification is ON");
}
} else {
toggle = NO;
}
}
if ([cellDelegate respondsToSelector:@selector(notificationReqd:)]) {
[cellDelegate notificationReqd:self];
}
}
【问题讨论】:
-
你有什么问题?您包含了一些表格代码,但其中没有包含 UISwitches ——您可能会更幸运地获得特定问题的答案以及您已经在代码中尝试过的东西。

我想弄清楚如何将 uiswitches 添加到 tableviewcell 中
