UITableView 单元格在滚动时重复并相互重叠。我该如何解决这个问题
这是我的代码
- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section
{
return 11;
}
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
UIButton *buyBtn = [UIButton buttonWithType:UIButtonTypeCustom];
UIImageView *img;
UILabel *lbl;
UIImageView *backImage;
UILabel *textLabel;
UILabel *detailTextLabel;
NSInteger val = [indexPath row] * 3;
if (UI_USER_INTERFACE_IDIOM() == UIUserInterfaceIdiomPad)
{
backImage = [[UIImageView alloc] initWithFrame:CGRectMake(2, 4, 316, 62)];
[buyBtn setFrame:CGRectMake(257, 35, 57, 24)];
img = [[UIImageView alloc] initWithFrame:CGRectMake(257, 10, 57, 24)];
lbl = [[UILabel alloc] initWithFrame:CGRectMake(0, 0, 57, 24)];
textLabel = [[UILabel alloc] initWithFrame:CGRectMake(4, 4, 230, 25)];
detailTextLabel = [[UILabel alloc] initWithFrame:CGRectMake(4, 25, 230, 30)];
backImage.image = [UIImage imageNamed:@"shop-bg.png"];
[buyBtn setImage:[UIImage imageNamed:@"buy_button"] forState:UIControlStateNormal];
[img setImage:[UIImage imageNamed:@"price_button.png"]];
}
else
{
backImage = [[UIImageView alloc] initWithFrame:CGRectMake(2, 4, 316, 62)];
[buyBtn setFrame:CGRectMake(257, 35, 57, 24)];
img = [[UIImageView alloc] initWithFrame:CGRectMake(257, 10, 57, 24)];
lbl = [[UILabel alloc] initWithFrame:CGRectMake(0, 0, 57, 24)];
textLabel = [[UILabel alloc] initWithFrame:CGRectMake(4, 4, 230, 25)];
detailTextLabel = [[UILabel alloc] initWithFrame:CGRectMake(4, 25, 230, 30)];
backImage.image = [UIImage imageNamed:@"shop-bg.png"];
[buyBtn setImage:[UIImage imageNamed:@"buy_button"] forState:UIControlStateNormal];
[img setImage:[UIImage imageNamed:@"price_button.png"]];
}
lbl.center = img.center;
lbl.textAlignment = UITextAlignmentCenter;
lbl.text = [self.original_List objectAtIndex:val+2];
lbl.backgroundColor = [UIColor clearColor];
textLabel.font = [UIFont fontWithName:@"Arial Rounded MT Bold" size:14];
textLabel.backgroundColor = [UIColor clearColor];
textLabel.text = [self.original_List objectAtIndex:val];
detailTextLabel.text = [self.original_List objectAtIndex:val+1];
detailTextLabel.backgroundColor = [UIColor clearColor];
detailTextLabel.font = [UIFont fontWithName:@"Arial Rounded MT Bold" size:10];
textLabel.textColor = [UIColor blackColor];
detailTextLabel.textColor = [UIColor whiteColor];
detailTextLabel.numberOfLines = 2;
[buyBtn setTag:[indexPath row]];
[buyBtn addTarget:self action:@selector(buyBtnPressed:) forControlEvents:UIControlEventTouchDown];
static NSString *myIdentifier = @"myIdentifier";
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:myIdentifier];
NSLog(@"%d" , [[cell subviews] count]);
if (cell == nil)
{
cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:myIdentifier];
}
cell.accessoryType = UITableViewCellAccessoryNone;
[cell setSelectionStyle:UITableViewCellEditingStyleNone];
cell.backgroundColor = [UIColor clearColor];
[cell.contentView addSubview:backImage];
[cell.contentView addSubview:detailTextLabel];
[cell.contentView addSubview:textLabel];
[cell.contentView addSubview:buyBtn];
[cell.contentView addSubview:img];
[cell.contentView addSubview:lbl];
return cell;
