ios - UITableViewCell 内容未填满整个单元格

Question

我正在尝试在我的应用程序中实现自定义 UITableViewCells。我想向每个 UITableViewCell 添加一个带有多个 subview 的 UIScrollView 并启用水平滚动。除了高度和分组之外，我基本上都能做到。查看下面我的代码和屏幕截图。我无法将 UIScrollView 的高度更改为大于 44 点的数字。

如何将高度大于 44 的 UIScrollView 添加到我的自定义 UITableViewCell？

#import "HomeViewController.h"

@interface HomeViewController ()

@end

@implementation HomeViewController

- (id)initWithNibName:(NSString *)nibNameOrNil bundle:(NSBundle *)nibBundleOrNil
{
    self = [super initWithNibName:nibNameOrNil bundle:nibBundleOrNil];
    if (self) {
        // Custom initialization
    }
    return self;
}

- (void)viewDidLoad
{
    [super viewDidLoad];
    // Do any additional setup after loading the view.
}

- (void)didReceiveMemoryWarning
{
    [super didReceiveMemoryWarning];
    // Dispose of any resources that can be recreated.
}

- (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView
{
    // Return the number of sections.
    return 1;
}

- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section
{
    return 2;
}

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
    static NSString *CellIdentifier = @"Home Scroll Cell";
    homeScrollCell *cell =[tableView dequeueReusableCellWithIdentifier:CellIdentifier];

    if (!cell) {
        cell = [[homeScrollCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier];
    }


    NSLog(@"Cell: %f", cell.bounds.size.height);




    return cell;
}


- (CGFloat)tableView:(UITableView *)tableView heightForRowAtIndexPath:(NSIndexPath *)indexPath
{
    return 100.0;
}

@end

UITableCell 类

#import "homeScrollCell.h"

@implementation homeScrollCell

//- (id)initWithStyle:(UITableViewCellStyle)style reuseIdentifier:(NSString *)reuseIdentifier
//{
//
//}

-(id) initWithStyle:(UITableViewCellStyle)style reuseIdentifier:(NSString *)reuseIdentifier
{
    self = [super initWithStyle:style reuseIdentifier:reuseIdentifier];
    if (self)
    {
        scrollView = [[UIScrollView alloc] initWithFrame:CGRectMake(0, 0, self.bounds.size.width, 100)];
        NSInteger viewcount= 3;
        for(int i = 0; i< viewcount; i++) {

            CGFloat x = i * self.bounds.size.width;
            HomeTodayView *view = [[HomeTodayView alloc] initWithFrame:CGRectMake(x, 0,self.bounds.size.width, self .bounds.size.height)];
            view.backgroundColor = [UIColor greenColor];

            [scrollView addSubview:view];

        }
        scrollView.contentSize = CGSizeMake(self.bounds.size.width *viewcount, 100);
        scrollView.pagingEnabled = YES;
        scrollView.bounces = NO;
        [self addSubview:scrollView];


        NSLog(@"Height: %f", self.bounds.size.height);
    }
    return self;
}

- (void)setSelected:(BOOL)selected animated:(BOOL)animated
{
  //  [super setSelected:selected animated:animated];

    // Configure the view for the selected state
}

@end

将 UIScrollView 的框架设置为 tableViewCell 的边界(或框架，我从来不记得):

scrollView = [[UIScrollView alloc] initWithFrame:self.bounds];

然后将其高度设置为autoResize

scrollView.autoresizingMask = UIViewAutoresizingFlexibleHeight;

您不必手动更改实际单元格内的单元格高度。高度应该全部在 TableViewController 的委托(delegate)方法中进行管理。
