发生了一个奇怪的问题，我在单元格中放置了一些文本（使用cell.textLabel）和一个小“勾号”图形。当我选择单元格时，应该显示标记，如果已经存在，则消失。实际上发生的是滴答滴答然后几乎立即淡出。这都是非常标准的代码，所以如果任何人有任何想法发生了什么，我会很高兴听到！UITableView单元格中的图形消失
-(UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
NSUInteger section = [indexPath section];
NSUInteger row = [indexPath row];
static NSString *CellIdentifier = @"Cell";
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
if (cell == nil) {
cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier] autorelease];
} else {
while ([[cell.contentView subviews] count] > 0) {
UIView *labelToClear = [[cell.contentView subviews] objectAtIndex:0];
[labelToClear removeFromSuperview];
}
}
NSString *theName = [[contacts objectForKey:[contactsKeys objectAtIndex:section]] objectAtIndex:row];
cell.textLabel = theName;
if (section == 0) {
cell.textLabel.textAlignment = UITextAlignmentCenter;
} else {
cell.textLabel.textAlignment = UITextAlignmentLeft;
}
if ([selectedContacts containsObject:theName]) {
CGFloat cellRight = tableView.frame.size.width - 70;
UIImage *theTickImage = [UIImage imageNamed:@"Tick.png"];
UIImageView *theTickImageView = [[[UIImageView alloc] initWithImage:theTickImage] autorelease];
theTickImageView.frame = CGRectMake(cellRight, 10, theTickImage.size.width, theTickImage.size.height);
[cell.contentView addSubview:theTickImageView];
}
return cell;
}
非常感谢您的帮助！
