UITableViewCell 内容没有填满整个单元格 [英] UITableViewCell content not filling up whole cell

问题描述

我正在尝试在我的应用中实现自定义 UITableViewCells.我想向每个 UITableViewCell 添加一个带有多个子视图的 UIScrollView 并启用水平滚动.除了高度和分组之外，我大部分时间都能做到.在下面查看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.

I am trying to implement custom UITableViewCells in my app. I want to add a UIScrollView with several subviews to each UITableViewCell and enable horizontal scrolling. I was mostly able to do it except with the height and grouping. Check out my code and screenshot below. I am not able to change the UIScrollView's height to a number greater than 44 points.

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

How can I add a UIScrollView, with a height greater than 44, to my custom 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

UITableCell class

#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

推荐答案

将 UIScrollView 的框架设置为 tableViewCell 的边界(或框架，我从不记得我的头顶):

Set the UIScrollView's frame to be the tableViewCell's bounds (or frame, I never remember off the top of my head):

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

然后将其高度设置为 autoResize

Then set it's height to autoResize

scrollView.autoresizingMask = UIViewAutoresizingFlexibleHeight;

您不必在实际单元格中手动更改单元格的高度.高度应该全部在 TableViewController 的委托方法中管理.

You shouldn't have to manually change the cell's height within the actual cell. The height should all be managed in your TableViewController's delegate methods.
