出于工作目的,我需要创建一个嵌入 UIView 的 UIScrollView,而 UIView 又通过 Xcode 中的容器功能嵌入 UITableView。
我的 UIScrollView 是启用了分页的整页滚动视图。我的 UIView 充满了 UIImage、一些 UIButton 和一个链接到 UITableView 的容器。
在初始启动时,数据已完美加载,这意味着 UITableView 已填充数据,UIImage 已填充,并且按钮放置正确。
但是由于某些奇怪的原因,当我尝试在容器中的 UITableView 中点击或滚动时,我的 UITableView 中的所有数据都会被清除。
我在这里发布这个问题,因为我没有在 StackOverFlow 或任何其他网站上发现任何其他类似的问题。
UITableView代码:
- (void)viewDidLoad
{
[super viewDidLoad];
[self.productTable setBackgroundView:nil];
self.productTable.backgroundColor = [UIColor clearColor];
self.productTable.delegate = self;
self.productTable.dataSource = self;
}
- (void) viewDidAppear:(BOOL)animated {
/*CGSize tmp = self.productTable.contentSize;
self.productTable.frame = CGRectMake(0, 0, tmp.width, tmp.height * 3);*/
}
- (void)didReceiveMemoryWarning
{
[super didReceiveMemoryWarning];
// Dispose of any resources that can be recreated.
}
#pragma mark - Table view data source
- (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView
{
// Return the number of sections.
NSLog(@"section count : %i", [self.Products count]);
return [self.Products count];
}
- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section
{
xcsSectionInfo *sectionInfo = [self.Products objectAtIndex:section];
if (sectionInfo.isOpen == NO) {
return 1;
} else {
return 3;
}
}
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
xcsSectionInfo *sectionInfo = [self.Products objectAtIndex:indexPath.section];
if (indexPath.row == 0) {
static NSString *CellIdentifier = @"Header";
xcsProductHeaderCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier forIndexPath:indexPath];
cell.articleNumber.text = sectionInfo.product.articleNumber;
cell.articleColor.text = sectionInfo.product.articleColor;
cell.backgroundColor = [UIColor grayColor];
if (sectionInfo.isOpen == YES && sectionInfo == self.currentSectionInfo) {
cell.expandImage.image = [UIImage imageNamed:@"arrow_down.png"];
} else if (sectionInfo.isOpen == NO) {
cell.expandImage.image = [UIImage imageNamed:@"arrow_up.png"];
}
return cell;
} else if (indexPath.row == 1) {
static NSString *CellIdentifier = @"ProductHeader";
xcsProductTitleCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier forIndexPath:indexPath];
cell.colorTempHeader.text = @"Color Temperature";
cell.sourceQualityHeader.text = @"Source Quality";
cell.sourceTypeHeader.text = @"Source Type";
cell.luminaireFluxHeader.text = @"Luminaire Flux";
cell.powerConsumptionHeader.text = @"Power Consumption";
cell.luminaireEfficacyHeader.text = @"Luminaire Efficacy";
cell.backgroundColor = [UIColor grayColor];
return cell;
} else if (indexPath.row == 2) {
static NSString *CellIdentifier = @"Product";
xcsProductCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier forIndexPath:indexPath];
cell.colorTemp.text = sectionInfo.product.colorTemperature;
cell.sourceQuality.text = sectionInfo.product.sourceQuality;
cell.sourceType.text = sectionInfo.product.sourceType;
cell.luminaireFlux.text = sectionInfo.product.luminaireFlux;
cell.powerConsumption.text = sectionInfo.product.powerConsumption;
cell.luminaireEfficacy.text = sectionInfo.product.luminaireEfficacy;
cell.backgroundColor = [UIColor grayColor];
return cell;
}
}
#pragma mark - Table view delegate
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
xcsSectionInfo *sectionInfo = [self.Products objectAtIndex:indexPath.section];
NSIndexPath *path0 = [NSIndexPath indexPathForRow:[indexPath row]+1 inSection:[indexPath section]];
NSIndexPath *path1 = [NSIndexPath indexPathForRow:[indexPath row]+2 inSection:[indexPath section]];
NSArray *indexPathArray = [NSArray arrayWithObjects: path0, path1, nil];
if (sectionInfo.isOpen == NO) {
sectionInfo.isOpen = YES;
[tableView insertRowsAtIndexPaths:indexPathArray withRowAnimation:NO];
} else {
sectionInfo.isOpen = NO;
[tableView deleteRowsAtIndexPaths:indexPathArray withRowAnimation:NO];
}
[self.Products replaceObjectAtIndex:indexPath.section withObject:sectionInfo];
[tableView deselectRowAtIndexPath:indexPath animated:YES];
self.currentSectionInfo = sectionInfo;
[tableView reloadData];
}
顺便说一句:我正在使用故事板
提前致以问候和感谢。
