当我滚动UITableView时,我的tableview单元格会自动取消选中。但是,当我按下完成按钮时,它会给我选择的行,我无法理解为什么会发生这种情况。
我的Tableview代码如下:
- (void)viewDidLoad
{
[super viewDidLoad];
// Do any additional setup after loading the view from its nib.
idArray = [[NSMutableArray alloc]init];
NSLog(@"Cat Array : %@",catArray);
isSelectAllBtnClicked = NO;
serviceArray = [[NSArray alloc]initWithObjects:@"Anal", @"Cuffed", @"Foreplay", @"Masturbation", @"Scat", @"Blindfolded",@"Deep throat", @"French Kissing", @"Missionary", @"Shower for 2", @"Bottom", @"Dinner Date", @"Full Bondage", @"Mutual Masturbation", @"Spanking", @"Boy on Boy", @"Dirty Talk",@"Girl on Girl", @"On top", @"Strap on", @"Choking", @"Doggy", @"Girlfriend Experience", @"Oral", @"Striptease", @"CIM", @"Dominate", @"Golden Shower",@"Oral Mutual", @"Submissive", @"COB", @"Fantasy", @"Kissing", @"Overnight", @"Top", @"COF", @"Fetish", @"Light Bondage", @"Rim me",@"Touching", @"Couples", @"Fisting", @"Lingerie", @"Rim you", @"Toys for me", @"Cuddling", @"Foot fetish", @"Massage", @"Role Play", @"Toys for you", nil];
[myTableView reloadData];
}
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
static NSString *reuseIdentifier = @"reuseIdentifier";
UITableViewCell *cell = [[UITableViewCell alloc]init];
if (cell != NULL)
{
cell = [[UITableViewCell alloc]initWithStyle:UITableViewCellStyleDefault reuseIdentifier:reuseIdentifier];
}
cell.selectionStyle = UITableViewCellEditingStyleNone;
cell.backgroundView = [[[UIImageView alloc] initWithImage:[UIImage imageNamed:@"list_row_bg.png"]] autorelease];
UILabel *catListLbl = [[UILabel alloc] initWithFrame:CGRectMake(20, 10, 310, 20)];
NSString *strValue = [[NSUserDefaults standardUserDefaults]valueForKey:@"service"];
if ([strValue isEqualToString:@"service"])
{
catListLbl.text = [serviceArray objectAtIndex:indexPath.row];
topHaderLabel.text = @"Choose Services";
}
else
{
catListLbl.text = [catArray objectAtIndex:indexPath.row];
topHaderLabel.text = @"Choose Category";
}
catListLbl.textColor = [UIColor colorWithRed:244/255.0 green:29/255.0 blue:94/255.0 alpha:1.0];
catListLbl.backgroundColor = [UIColor clearColor];
[cell addSubview:catListLbl];
if (isSelectAllBtnClicked) {
UIButton *unCheckBtn = [[UIButton alloc]initWithFrame:CGRectMake(270, 10, 20, 20)];
[unCheckBtn setBackgroundImage:[UIImage imageNamed:@"checkbox_check.png"] forState:UIControlStateNormal];
unCheckBtn.tag = indexPath.row + 200;
//NSLog(@"%i",unCheckBtn.tag);
[cell addSubview:unCheckBtn];
[myTableView selectRowAtIndexPath:indexPath animated:YES scrollPosition:UITableViewScrollPositionNone];
[self tableView:myTableView didSelectRowAtIndexPath:indexPath];
}
else {
UIButton *unCheckBtn = [[UIButton alloc]initWithFrame:CGRectMake(270, 10, 20, 20)];
[unCheckBtn setBackgroundImage:[UIImage imageNamed:@"checkbox.png"] forState:UIControlStateNormal];
unCheckBtn.tag = indexPath.row + 200;
//NSLog(@"%i",unCheckBtn.tag);
[cell addSubview:unCheckBtn];
}
return cell;
}
-(void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
int buttonTag = indexPath.row + 200;
//NSLog(@"%i",buttonTag);
UIButton *tempBtn = (UIButton *)[self.view viewWithTag:buttonTag];
[tempBtn setBackgroundImage:[UIImage imageNamed:@"checkbox_check.png"]forState:UIControlStateNormal];
}
-(void)tableView:(UITableView *)tableView didDeselectRowAtIndexPath:(NSIndexPath *)indexPath
{
int buttonTag = indexPath.row + 200;
NSLog(@"%i",buttonTag);
UIButton *tempBtn = (UIButton *)[self.view viewWithTag:buttonTag];
[tempBtn setBackgroundImage:[UIImage imageNamed:@"checkbox.png"]forState:UIControlStateNormal];
}
-(NSInteger)numberOfSectionsInTableView:(UITableView *)tableView
{
return 1;
}
-(NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section
{
int count;
NSString *strValue = [[NSUserDefaults standardUserDefaults]valueForKey:@"service"];
if ([strValue isEqualToString:@"service"])
{
count = [serviceArray count];
}
else
{
count = [catArray count];
}
return count;
}
-(CGFloat)tableView:(UITableView *)tableView heightForRowAtIndexPath:(NSIndexPath *)indexPath
{
return 40;
}
提前感谢。

什么时候滚动表格
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
方法执行,并且您没有提到任何可以判断此行是否先前被选中的条件。你必须与indexPath.row一起插入一个条件,并检查它是否被选中

尝试这样,每当isSelectAllBtnClicked值为0时滚动tableview,这就是每次按钮更改的原因。
每次创建新单元格时滚动表格都会尝试避免使用该单元格
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
NSString *CellIdentifier = [NSString stringWithFormat:@"%d",indexPath.row];
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
if (cell == nil) {
cell.selectionStyle = UITableViewCellEditingStyleNone;
cell.backgroundView = [[[UIImageView alloc] initWithImage:[UIImage imageNamed:@"list_row_bg.png"]] autorelease];
UILabel *catListLbl = [[UILabel alloc] initWithFrame:CGRectMake(20, 10, 310, 20)];
NSString *strValue = [[NSUserDefaults standardUserDefaults]valueForKey:@"service"];
if ([strValue isEqualToString:@"service"])
{
catListLbl.text = [serviceArray objectAtIndex:indexPath.row];
topHaderLabel.text = @"Choose Services";
}
else
{
catListLbl.text = [catArray objectAtIndex:indexPath.row];
topHaderLabel.text = @"Choose Category";
}
catListLbl.textColor = [UIColor colorWithRed:244/255.0 green:29/255.0 blue:94/255.0 alpha:1.0];
catListLbl.backgroundColor = [UIColor clearColor];
[cell addSubview:catListLbl];
if (isSelectAllBtnClicked) {
UIButton *unCheckBtn = [[UIButton alloc]initWithFrame:CGRectMake(270, 10, 20, 20)];
[unCheckBtn setBackgroundImage:[UIImage imageNamed:@"checkbox_check.png"] forState:UIControlStateNormal];
unCheckBtn.tag = indexPath.row + 200;
//NSLog(@"%i",unCheckBtn.tag);
[cell addSubview:unCheckBtn];
[myTableView selectRowAtIndexPath:indexPath animated:YES scrollPosition:UITableViewScrollPositionNone];
[self tableView:myTableView didSelectRowAtIndexPath:indexPath];
}
else {
UIButton *unCheckBtn = [[UIButton alloc]initWithFrame:CGRectMake(270, 10, 20, 20)];
[unCheckBtn setBackgroundImage:[UIImage imageNamed:@"checkbox.png"] forState:UIControlStateNormal];
unCheckBtn.tag = indexPath.row + 200;
//NSLog(@"%i",unCheckBtn.tag);
[cell addSubview:unCheckBtn];
}
}
}
