【问题描述】:
我不明白为什么第一节标题没有显示。第二和第三显示很好。我怀疑这是因为搜索栏。
我试过像UISearchBar covered by section header 那样偏移整个表格,但我没有注意到它偏移了。
- (UIView *)tableView:(UITableView *)tableView viewForHeaderInSection:(NSInteger)section {
// create the parent view that will hold header Label
UIView* customView = [[UIView alloc] initWithFrame:CGRectMake(0,-60,300,60)];
// create the label object
UILabel *headerLabel = [[UILabel alloc] initWithFrame:CGRectZero];
headerLabel.frame = CGRectMake(0,0,self.view.frame.size.width,60);
UIColor* mainColor = [UIColor colorWithRed:47.0/255 green:168.0/255 blue:228.0/255 alpha:1.0f];
headerLabel.backgroundColor = mainColor;
headerLabel.font = [UIFont boldSystemFontOfSize:18];
headerLabel.textAlignment = UITextAlignmentCenter;
if(section == 0)
headerLabel.text = @"Friends";
if(section == 1)
headerLabel.text = @"Second Section Header";
if(section == 2)
headerLabel.text = @"Third Section Header";
headerLabel.textColor = [UIColor whiteColor];
[customView addSubview:headerLabel];
return customView;
}
- (void) hideSearchBar
{
self.feedTableView.contentOffset = CGPointMake( 0, self.searchBar.frame.size.height );
}
- (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView
{
return 3;
}
- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section {
//Number of rows it should expect should be based on the section
NSDictionary *dictionary = [_imageDataArray objectAtIndex:section];
NSArray *array = [dictionary objectForKey:@"data"];
return [array count];
}
【问题讨论】:
-
它对我来说非常完美,您是否更改了任何约束或任何约束?
-
无限制。当我将搜索栏从情节提要的表格中移出/上方时,我可以看到标题的空间,但它是空白的...搜索栏层次结构是否正常?
-
是的,我只像这样设置层次结构
