我有UITableView控制器,它使用自定义节标题视图。当我的设备是肖像时,它显示完美。而当我的设备是风景时它再次完美。但是当在app运行时期间更改方向时,它不会更新我的剖面视图。有什么问题?
使用以下代码,我将向视图添加标签和两个按钮,并在“viewForHeaderInSection”中返回该视图。在调试过程中,我发现该方法被调用,但是节头视图没有更新。
- (CGFloat)tableView:(UITableView *)tableView heightForHeaderInSection:(NSInteger)section
{
return 80;
}
- (UIView *)tableView:(UITableView *)tableView viewForHeaderInSection:(NSInteger)section
{
NSDictionary* dict = [threadsArray objectAtIndex:section];
UIView* headerView = [[UIView alloc] initWithFrame:CGRectMake(0, 0, self.view.frame.size.width, 80)];
headerView.backgroundColor = [UIColor colorWithRed:0.0 green:0.0 blue:1.0 alpha:0.2];
UILabel *newLabel = [[UILabel alloc] initWithFrame:CGRectMake(20, 15, self.view.frame.size.width - 98, 21)];
newLabel.textColor = [UIColor blackColor];
newLabel.font = [UIFont boldSystemFontOfSize:17];
newLabel.text = [dict objectForKey:@"Name"];
newLabel.backgroundColor = [UIColor clearColor];
[headerView addSubview:newLabel];
UIButton* addButton = [UIButton buttonWithType:UIButtonTypeContactAdd];
addButton.frame = CGRectMake(self.view.frame.size.width - 88, 11, 29, 29);
NSLog(@"%f %f %f %f",addButton.frame.origin.x,addButton.frame.origin.y, addButton.frame.size.width,addButton.frame.size.height);
[addButton addTarget:self action:@selector(addThreadResponseClicked:) forControlEvents:UIControlEventTouchDown];
[headerView addSubview:addButton];
UIButton* expandCollapseButton = [UIButton buttonWithType:UIButtonTypeCustom];
[expandCollapseButton setImage:[UIImage imageNamed:@"Expand.png"] forState:UIControlStateNormal];
expandCollapseButton.frame = CGRectMake(self.view.frame.size.width - 48, 11, 29, 29);
NSLog(@"%f %f %f %f",expandCollapseButton.frame.origin.x,expandCollapseButton.frame.origin.y, expandCollapseButton.frame.size.width,expandCollapseButton.frame.size.height);
[expandCollapseButton addTarget:self action:@selector(expandCollapseHeader:) forControlEvents:UIControlEventTouchDown];
[headerView addSubview:expandCollapseButton];
addButton.tag = expandCollapseButton.tag = section;
return [headerView autorelease];
}
答案 0 :(得分:1)
尝试适当地设置视图autoresizing masks:例如,对于headerView;
[headerView setAutoresizingMask:UIViewAutoresizingFlexibleWidth];
并且对于addButton和expandCollapseButton,将AutoresizingMask设置为:
UIViewAutoresizingMaskFlexibleLeftMargin
