我有一个UITableView
称为症状表...当UISwitch
处于开启状态时可以采取补救措施我在症状表单元素上显示UIImage
以突出显示UISwitch
是打开那个单元格。当我在第一个症状的可补救措施中打开时,我正在显示UISwitch
但是细胞正在重复使用,并且图像也显示在其他症状可见的细胞中。任何人都可以帮我解决这个问题吗?
-(UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
if (tableView==symptomsTableView)
{
PPsymptomTableCell *cell;
static NSString *cellIdentifier=@"cellIdentifier";
cell=[tableView dequeueReusableCellWithIdentifier:cellIdentifier];
if (cell==nil)
{
cell=[[PPsymptomTableCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:cellIdentifier];
cell.selectionStyle=UITableViewCellSelectionStyleNone;
}
int symptomIDSelected;
symptomIDSelected = [[[mainsymptArray objectAtIndex:indexPath.row]objectForKey:@"SymptID"]intValue];
NSLog(@"%d",[[activeNotificationDictionary objectForKey:[NSNumber numberWithInt:symptomIDSelected]]intValue]);
for (int i = 0; i<activeNotificationDictionary.count; i++)
{
if([[activeNotificationDictionary objectForKey:[NSNumber numberWithInt:symptomIDSelected]]intValue] == symptomIDSelected)
{
cell.selectedCellImageDisplay.hidden=NO;
}
else
{
cell.selectedCellImageDisplay.hidden=YES;
}
}
NSLog(@"end of symptoms cell for row");
if (searching==YES)
{
cell.symptomCellLabel.text=[[searchSymptomsArray objectAtIndex:indexPath.row] objectForKey:@"SymptName"];
cell.backgroundColor=[UIColor clearColor];
return cell;
}
else
{
cell.backgroundColor=[UIColor clearColor];
NSArray *sectionArray=[mainIndexDictionary objectForKey:[allKeysArray objectAtIndex:indexPath.section]];
cell.symptomCellLabel.text=[[sectionArray objectAtIndex:indexPath.row] objectForKey:@"SymptIndexName"];
return cell;
}
}
此处,activenotification字典是NSMutableDictionary
,其中包含该特定症状ID的remedyID值。
这是症状
UITableViewCell
- (id)initWithStyle:(UITableViewCellStyle)style reuseIdentifier:(NSString *)reuseIdentifier
{
self = [super initWithStyle:style reuseIdentifier:reuseIdentifier];
if (self)
{
self.backgroundColor = [UIColor clearColor];
self.contentView.backgroundColor = [UIColor clearColor];
self.symptomCellImageView.contentMode=UIViewContentModeScaleToFill;
selectedCellImageDisplay = [[UIImageView alloc]initWithImage:[UIImage imageNamed:@"selectedSymptomImage.png"]];
selectedCellImageDisplay.frame = CGRectMake(230.0, 8.0, 30.0, 30.0);
selectedCellImageDisplay.hidden=YES;
symptomCellLabel=[[UILabel alloc]initWithFrame:CGRectMake(15.0,0.0 ,280.0,40.0)];
symptomCellLabel.font=[UIFont fontWithName:@"Rockwell" size:17];
symptomCellLabel.textColor=[UIColor blackColor];
symptomCellLabel.backgroundColor=[UIColor clearColor];
[self.contentView addSubview:symptomCellLabel];
[self.contentView addSubview:selectedCellImageDisplay];
// Initialization code
}
return self;
}
答案 0 :(得分:7)
正在重复使用该单元格,因为您要求重用该单元格(dequeueReusableCellWithIdentifier:
)。由于可以重复使用该单元,因此必须明确设置所有 每个单元的功能,包括交换机的存在与否及其状态。
答案 1 :(得分:0)
您将UISwitch
放入单元格的哪个位置?每次出列或初始化单元格后,都需要确保设置开关的状态。
