ios - 自定义 UITableView Cell 中的按钮

Question

我有“滑动删除”TableViewCell 的功能。我想再添加一个删除按钮。请看图片

我正在使用这个 UITableView 委托(delegate)函数来删除 tableview 单元格。

- (void)tableView:(UITableView *)tableView commitEditingStyle:
  (UITableViewCellEditingStyle)editingStyle forRowAtIndexPath:(NSIndexPath *)indexPath

这可能吗，以及如何访问额外按钮？

谢谢。

请引用此链接并下载示例应用程序:https://github.com/boctor/idev-recipes/tree/master/SideSwipeTableView

并使用多个按钮自定义您的 uitableviewcell。

 UIScrollView *scrollView = [[UIScrollView alloc] initWithFrame:CGRectMake(0, 0, CGRectGetWidth(self.bounds), CGRectGetHeight(self.bounds))];
scrollView.contentSize = CGSizeMake(CGRectGetWidth(self.bounds) + kCatchWidth, CGRectGetHeight(self.bounds));
scrollView.delegate = self;
scrollView.showsHorizontalScrollIndicator = NO;

[self.contentView addSubview:scrollView];
self.scrollView = scrollView;

UIView *scrollViewButtonView = [[UIView alloc] initWithFrame:CGRectMake(CGRectGetWidth(self.bounds) - kCatchWidth, 0, kCatchWidth, CGRectGetHeight(self.bounds))];
self.scrollViewButtonView = scrollViewButtonView;
[self.scrollView addSubview:scrollViewButtonView];

// Set up our two buttons
UIButton *moreButton = [UIButton buttonWithType:UIButtonTypeCustom];
moreButton.backgroundColor = [UIColor colorWithRed:0.78f green:0.78f blue:0.8f alpha:1.0f];
moreButton.frame = CGRectMake(0, 0, kCatchWidth / 3.0f, CGRectGetHeight(self.bounds));
[moreButton setTitle:@"More" forState:UIControlStateNormal];
[moreButton setTitleColor:[UIColor whiteColor] forState:UIControlStateNormal];
[moreButton addTarget:self action:@selector(userPressedMoreButton:) forControlEvents:UIControlEventTouchUpInside];

[self.scrollViewButtonView addSubview:moreButton];

UIButton *shareButton = [UIButton buttonWithType:UIButtonTypeCustom];
shareButton.backgroundColor = [UIColor colorWithRed:0.0f green:0.0f blue:1.0f alpha:1.0f];
shareButton.frame = CGRectMake(kCatchWidth / 3.0f, 0, kCatchWidth / 3.0f, CGRectGetHeight(self.bounds));
[shareButton setTitle:@"Share" forState:UIControlStateNormal];
[shareButton setTitleColor:[UIColor whiteColor] forState:UIControlStateNormal];
[shareButton addTarget:self action:@selector(userPressedMoreButton:) forControlEvents:UIControlEventTouchUpInside];
[self.scrollViewButtonView addSubview:shareButton];

UIButton *deleteButton = [UIButton buttonWithType:UIButtonTypeCustom];
deleteButton.backgroundColor = [UIColor colorWithRed:1.0f green:0.231f blue:0.188f alpha:1.0f];
deleteButton.frame = CGRectMake(kCatchWidth / 3.0f+kCatchWidth / 3.0f, 0, kCatchWidth / 3.0f, CGRectGetHeight(self.bounds));
[deleteButton setTitle:@"Delete" forState:UIControlStateNormal];
[deleteButton setTitleColor:[UIColor whiteColor] forState:UIControlStateNormal];
[deleteButton addTarget:self action:@selector(userPressedDeleteButton:) forControlEvents:UIControlEventTouchUpInside];
[self.scrollViewButtonView addSubview:deleteButton];

UIView *scrollViewContentView = [[UIView alloc] initWithFrame:CGRectMake(0, 0, CGRectGetWidth(self.bounds), CGRectGetHeight(self.bounds))];
scrollViewContentView.backgroundColor = [UIColor whiteColor];
[self.scrollView addSubview:scrollViewContentView];
self.scrollViewContentView = scrollViewContentView;

UILabel *scrollViewLabel = [[UILabel alloc] initWithFrame:CGRectInset(self.scrollViewContentView.bounds, 10, 0)];
self.scrollViewLabel = scrollViewLabel;
[self.scrollViewContentView addSubview:scrollViewLabel];

我已经用我的应用程序实现了这段代码，得到了这样的结果。您可以和单元格滑动中的按钮数量。

这是实现的屏幕截图

滑动单元格后，出现“更多”、“分享”、“删除”的 3 个按钮。
