最近做项目有个需求是向左滑动cell出现删除和分享按钮，要求显示图片没有文字。代码：实现一下tableView.m (- (nullable NSArray)tableView:(UITableView )tableView editActionsForRowAtIndexPath:(NSIndexPath *)indexPath NS_AVAILABLE_IOS(8_0) __TVOS_PROHIBITED; )
- (NSArray *)tableView:(UITableView *)tableView editActionsForRowAtIndexPath:(NSIndexPath *)indexPath
{
//UITableViewRowAction是iOS8才有的，title不想要打了空格占着大小
UITableViewRowAction *deleteRowAction = [UITableViewRowAction rowActionWithStyle:UITableViewRowActionStyleDestructive title:@" " handler:^(UITableViewRowAction *action, NSIndexPath *indexPath) {
NSLog(@"点击删除");
}];
UITableViewRowAction *shareRowAction = [UITableViewRowAction rowActionWithStyle:UITableViewRowActionStyleNormal title:@" " handler:^(UITableViewRowAction *action, NSIndexPath *indexPath) {
NSLog(@"点击分享");
}];
// 这个地方：先加入的在右边
return @[shareRowAction, deleteRowAction];
}
cell.m (在- (void)layoutSubviews; 这个方法里做处理)
for (UIView *subView in self.subviews) {
if([subView isKindOfClass:NSClassFromString(@"UITableViewCellDeleteConfirmationView")]) {
// 拿到subView之后再获取子控件
// 因为上面删除按钮是第二个加的所以下标是1
UIView *deleteConfirmationView = subView.subviews[1];
//改背景颜色
deleteConfirmationView.backgroundColor = [UIColor colorWithRed:204.0/255.0 green:42.0/255.0 blue:62.0/255.0 alpha:1.0];
for (UIView *deleteView in deleteConfirmationView.subviews) {
NSLog(@"%@",deleteConfirmationView.subviews);
UIImageView *deleteImage = [[UIImageView alloc] init];
deleteImage.contentMode = UIViewContentModeScaleAspectFit;
deleteImage.image = [UIImage imageNamed:delete];
deleteImage.frame = CGRectMake(0, 0, deleteView.frame.size.width, deleteView.frame.size.height);
[deleteView addSubview:deleteImage];
}
// 这里是右边的
UIView *shareConfirmationView = subView.subviews[0];
shareConfirmationView.backgroundColor = [UIColor colorWithRed:142.0/255.0 green:201.0/255.0 blue:75.0/255.0 alpha:1.0];
for (UIView *shareView in shareConfirmationView.subviews) {
UIImageView *shareImage = [[UIImageView alloc] init];
shareImage.contentMode = UIViewContentModeScaleAspectFit;
shareImage.image = [UIImage imageNamed:share];
shareImage.frame = CGRectMake(0, 0, shareView.frame.size.width, shareView.frame.size.height);
[shareView addSubview:shareImage];
}
}
}

看图层发现加了很多图片的，因为layoutSubviews会调用多次，可以把控件懒加载就行了，或者其实UITableViewCellDeleteConfirmationView里的控件本质上是UIButton，直接设置图片。
