Question

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

所以我还是想写：

[cell setAccessoryType:UITableViewCellAccessoryCheckmark];

但是我想要显示自己的图像而不是默认图像。

非常感谢任何帮助。

Answer 1

myUITableViewCell.accessoryView = myImageView;

然后将您的图像放入UIImageView。

方式-1：

我认为你可以使用

假设您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：event：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]; }

我已从此链接获取以上代码：

方式-2：

还有一种方法可以使用自定义tableView单元格。

我认为您必须制作一个自定义单元格并在单元格的右侧添加一个imageView。

然后，此imageView将保留您想要的图像。

在didSelectRowAtRowAtIndexPath上：您可以添加图像并根据点击次数删除。

如果您需要更多帮助，请告诉我。

希望这有帮助。

看一下这段代码：

- (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];
    }
