将UITableView的默认选中标记replace为自定义图像

我想要replaceUITableViewCell附件设置为时显示的默认复选标记图像：UITableViewCellAccessoryCheckmark。

所以我仍然想写：

[cell setAccessoryType:UITableViewCellAccessoryCheckmark]; 

但是我想要显示自己的形象，而不是默认的。

任何帮助深表感谢。

方法1：

我想你可以使用

假设你有一个带有复选标记图像的UIButton。

在cellForRowAtIndexPath:

 UIButton *button = [UIButton buttonWithType:UIButtonTypeCustom]; CGRect frame = CGRectMake(0.0, 0.0, image.size.width, image.size.height); button.frame = frame; [button setBackgroundImage:image forState:UIControlStateNormal]; [button addTarget:self action:@selector(checkButtonTapped:event:) forControlEvents:UIControlEventTouchUpInside]; button.backgroundColor = [UIColor clearColor]; cell.accessoryView = button; 

checkButtonTapped：事件：方法：

 - (void)checkButtonTapped:(id)sender event:(id)event { NSSet *touches = [event allTouches]; UITouch *touch = [touches anyObject]; CGPoint currentTouchPosition = [touch locationInView:self.tableView]; NSIndexPath *indexPath = [self.tableView indexPathForRowAtPoint: currentTouchPosition]; if (indexPath != nil) { [self tableView: self.tableView accessoryButtonTappedForRowWithIndexPath: indexPath]; } } 

accessoryButtonTappedForRowWithIndexPath：方法

 - (void)tableView:(UITableView *)tableView accessoryButtonTappedForRowWithIndexPath:(NSIndexPath *)indexPath { NSMutableDictionary *item = [dataArray objectAtIndex:indexPath.row]; BOOL checked = [[item objectForKey:@"checked"] boolValue]; [item setObject:[NSNumber numberWithBool:!checked] forKey:@"checked"]; UITableViewCell *cell = [item objectForKey:@"cell"]; UIButton *button = (UIButton *)cell.accessoryView; UIImage *newImage = (checked) ? [UIImage imageNamed:@"unchecked.png"] : [UIImage imageNamed:@"checked.png"]; [button setBackgroundImage:newImage forState:UIControlStateNormal]; } 

我从这个链接采取了上面的代码：

在iPhone中为UITableView实现自定义的附件视图

方法2：

还有一种方法可以使用自定义tableView单元格。

我认为你必须做一个自定义的单元格，并在单元格的右侧添加一个imageView。

这imageView将然后保存你想要的图像。

在didSelectRowAtRowAtIndexPath：你可以添加图像，并根据水龙头的数量删除。

请让我知道你是否需要更多的帮助。

希望这可以帮助。

Answer 2

 myUITableViewCell.accessoryView = myImageView; 

然后把你的图像放在UIImageView中。

看这个代码：

 - (UITableViewCell *)cellForRowAtIndexPath:(NSIndexPath *)indexPath { ... NSMutableDictionary *item = [dataArray bjectAtIndex:indexPath.row]; cell.textLabel.text = [item objectForKey:@"text"]; [item setObject:cell forKey:@"cell"]; BOOL checked = [[item objectForKey:@"checked"] boolValue]; UIImage *image = (checked) ? [UIImage imageNamed:@"checked.png"] : [UIImage imageNamed:@"unchecked.png"]; UIButton *button = [UIButton buttonWithType:UIButtonTypeCustom]; CGRect frame = CGRectMake(0.0, 0.0, image.size.width, image.size.height); button.frame = frame; [button setBackgroundImage:image forState:UIControlStateNormal]; [button addTarget:self action:@selector(checkButtonTapped:event:) forControlEvents:UIControlEventTouchUpInside]; button.backgroundColor = [UIColor clearColor]; cell.accessoryView = button; ... } - (void)checkButtonTapped:(id)sender event:(id)event { NSSet *touches = [event allTouches]; UITouch *touch = [touches anyObject]; CGPoint currentTouchPosition = [touch locationInView:self.tableView]; NSIndexPath *indexPath = [self.tableView indexPathForRowAtPoint: currentTouchPosition]; if (indexPath != nil) { [self tableView: self.tableView accessoryButtonTappedForRowWithIndexPath: indexPath]; } } - (void)tableView:(UITableView *)tableView accessoryButtonTappedForRowWithIndexPath:(NSIndexPath *)indexPath { NSMutableDictionary *item = [dataArray objectAtIndex:indexPath.row]; BOOL checked = [[item objectForKey:@"checked"] boolValue]; [item setObject:[NSNumber numberWithBool:!checked] forKey:@"checked"]; UITableViewCell *cell = [item objectForKey:@"cell"]; UIButton *button = (UIButton *)cell.accessoryView; UIImage *newImage = (checked) ? [UIImage imageNamed:@"unchecked.png"] : [UIImage imageNamed:@"checked.png"]; [button setBackgroundImage:newImage forState:UIControlStateNormal]; }
