我在UITableView
中有一个相当复杂的表格。此表单在表格视图单元格中有一些UICollectionView
,还有一些选择器显示与日历应用程序相同的方式:
现在,当我在我的应用上执行此操作时,我UICollectionView
中的一个比它开始时更高 - 并且它继续前进(我添加了一个红色边框以确保它是UICollectionView
正在调整大小):
我尝试调试UICollectionView
视图属性,但它永远不会更改(并且它的getter / setter调用次数不超出我的预期) - 即使我在cellForRowAtIndexPath
打印它时它确实显示了调整大小。有什么方法可以更好地调试这个,或者有人处于同样的情况吗?
谢谢!
代码:
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
//self.campos is a dictionary with sections and rows stored
NSMutableArray *infoCampos = [[self.campos objectAtIndex:indexPath.section] objectForKey:@"campos"];
NSDictionary *infoCampo = [infoCampos objectAtIndex:indexPath.row];
if ([[infoCampo objectForKey:@"nome"] isEqualToString:@"dosePorComprimido"]) {
//Remove picker cell if finds it
for (infoCampo in infoCampos) {
if ([infoCampo objectForKey:@"view"] == self.dosagemMedicamento.view) {
[infoCampos removeObject:infoCampo];
[tableView reloadSections:[NSIndexSet indexSetWithIndex:indexPath.section] withRowAnimation:UITableViewRowAnimationAutomatic];
[tableView deselectRowAtIndexPath:indexPath animated:YES];
return;
}
}
//Insert new cell
infoCampo = [infoCampos objectAtIndex:indexPath.row];
[infoCampos addObject:@{@"tipo":@5, @"view":self.dosagemMedicamento.view, @"nome":[infoCampo objectForKey:@"nome"]}];
[tableView reloadSections:[NSIndexSet indexSetWithIndex:indexPath.section] withRowAnimation:UITableViewRowAnimationAutomatic];
[self.dosagemMedicamento.view.superview addConstraints:[NSLayoutConstraint constraintsWithVisualFormat:@"|[pickerDosagem]|" options:0 metrics:nil views:@{@"pickerDosagem":self.dosagemMedicamento.view}]];
}
}
- (CGFloat)tableView:(UITableView *)tableView heightForRowAtIndexPath:(NSIndexPath *)indexPath
{
NSDictionary *infoCampo = [[[self.campos objectAtIndex:indexPath.section] objectForKey:@"campos"] objectAtIndex:indexPath.row];
UIView *view;
if ([infoCampo objectForKey:@"view"]) {
view = (UIView *) [infoCampo objectForKey:@"view"];
return view.frame.size.height;
}
return 44.0f;
}
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:
(NSIndexPath *)indexPath
{
UITableViewCell *cell;
NSMutableDictionary *infoCampo = [[[self.campos objectAtIndex:indexPath.section] objectForKey:@"campos"] objectAtIndex:indexPath.row];
UIView *view;
cell = [tableView dequeueReusableCellWithIdentifier:[[infoCampo objectForKey:@"nome"] stringByAppendingString:@"ViewLinhaCellView"] forIndexPath:indexPath];
view = [cell viewWithTag:1];
[view addSubview:[infoCampo objectForKey:@"view"]];
return cell;
}
编辑:忘了提到我没有使用reloadData更新表视图,而只使用reloadRowsAtIndexPaths和reloadSections来更新所需的部分/行。所以这使得它更加怪异,因为我没有重新加载那个特定的部分。

答案 0 :(得分:2)
我认为你的问题出现在tableView:heightForRowAtIndexPath:
- (CGFloat)tableView:(UITableView *)tableView heightForRowAtIndexPath:(NSIndexPath *)indexPath
{
NSDictionary *infoCampo = [[[self.campos objectAtIndex:indexPath.section] objectForKey:@"campos"] objectAtIndex:indexPath.row];
UIView *view;
if ([infoCampo objectForKey:@"view"]) {
view = (UIView *) [infoCampo objectForKey:@"view"];
return view.frame.size.height;
}
return 44.0f;
}
视图可能会通过自动布局或其自动调整遮罩调整大小。这里没有足够的信息来确切说明原因,但是表视图和自动布局可能会有一些有趣的行为。我建议只返回你设置的高度,而不是从视图中获取高度:
- (CGFloat)tableView:(UITableView *)tableView heightForRowAtIndexPath:(NSIndexPath *)indexPath
{
NSDictionary *infoCampo = [[[self.campos objectAtIndex:indexPath.section] objectForKey:@"campos"] objectAtIndex:indexPath.row];
UIView *view;
if ([infoCampo objectForKey:@"view"]) {
if ([infoCampo objectForKey:@"viewHeight"]) {
return [[infoCampo objectForKey:@"viewHeight"] floatValue];
} else {
return 216.0f;
}
}
return 44.0f;
}
viewHeight
键允许您为每个单元格的视图指定自定义高度,但此实现还返回默认高度(216),该高度恰好是选择器视图的标准高度。
