如何删除UITableView中的缩进? [英] How can remove indentation in UITableView?

问题描述

首先，我是新手，我很可能忘记了一些非常简单的东西.

First of all, I am new at this and I am most likely forgetting something very simple.

问题:

我正在制作一个在 tableView 中显示来自imgur.com的随机图像的应用程序.出于某种原因，所有单元格的缩进量都很小，如下图所示.我在 storyboard 中进行了许多设置，并且没有运气来解决此问题.

I am making an application that displays random images from imgur.com in a tableView. For some reason all of the cells are indented a small amount as seen in the picture below. I have fiddled around with many settings in storyboard and have had no luck in fixing the issue.

这是tableView代码...

Here is the tableView code...

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

- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section {
// Return the number of rows in the section.
return (_images.count * 2);
}

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
UITableViewCell *cell = nil;

if (indexPath.row % 2 == 0) {
//content cell
    cell = [tableView dequeueReusableCellWithIdentifier:@"RandomImgurTableCell"];

    if (cell == nil) {
        cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault
                                       reuseIdentifier:@"RandomImgurTableCell"];
    }

    long row = [indexPath row] / 2;

    SDImageCache* myCache = [SDImageCache sharedImageCache];
    cell.imageView.image = [myCache imageFromDiskCacheForKey:_images[row]];

}
else if (indexPath.row % 2 == 1) {
//separator cell
    cell = [tableView dequeueReusableCellWithIdentifier:@"SeparatorCell"];

    if(cell == nil) {
    cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault
                                  reuseIdentifier:@"SeparatorCell"];
    }
}
if (indexPath.row == (_images.count * 2) - 3) {
    [self checkToLoadMoreImages];
    NSLog(@"Hit bottom of table, getting more images");
}
return cell;
}

这是我的 tableView 和单元格设置的图片...

推荐答案

为了消除缩进，请将分隔符插入设置为零.结果如下图所示.

In order to get rid of the indent, you set the separator insets to zero. The result is shown in the following image.

在代码中

myTableView.separatorInset = UIEdgeInsetsZero

在界面生成器中

注释

如果单元格导致缩进，则可以将以下行添加到 tableView:cellForRowAtIndexPath :

If the cells are causing the indent, then you can add the following lines to tableView:cellForRowAtIndexPath:

cell.separatorInset = UIEdgeInsetsZero
cell.preservesSuperviewLayoutMargins = false
cell.layoutMargins = UIEdgeInsetsZero

如果您仍支持iOS 8之前的版本，请参见此答案以获取更多详细信息.
