问题描述
我想替换UITableViewCell配件设置为时显示的默认复选标记图像：UITableViewCellAccessoryCheckmark。
I'd like to replace the default checkmark image that is shown when a UITableViewCell's accessory is set to: UITableViewCellAccessoryCheckmark.
所以我还是想写：
[cell setAccessoryType:UITableViewCellAccessoryCheckmark];
但是我希望显示自己的图像而不是默认图像。
But I'd like my own image to be shown rather than the default.
非常感谢任何帮助。
推荐答案
方法-1：
我认为你可以使用
假设你有一个带有复选标记图像的UIButton。
Suppose you have a UIButton with checkmark image.
On cellForRowAtIndexPath：
On 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：event：Method：
- (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：Method
- (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];
}

方法-2：
还有一种方法可以使用自定义tableView单元格。
Also there is a way to make it using custom tableView cell.
我认为你必须制作一个自定义单元格在单元格的右侧添加一个imageView。
I think you have to make a custom cell and add an imageView on right hand side of the cell.
此imageView将保留您想要的图像。
This imageView will then hold the image you want.
在didSelectRowAtRowAtIndexPath：您可以添加图像并根据点击次数删除。
On didSelectRowAtRowAtIndexPath: you can add the image and remove based on number of taps.
如果您需要更多帮助，请告诉我。
