Answer 1

答案2：你可以制定自己的方法并在那种情况下调用它。

int row=indexPath.row;

UIButton *trackImageOnMap=[[UIButton alloc] initWithFrame:CGRectMake(420, 9, 40, 50)];
[trackImageOnMap setImage:[UIImage imageNamed:@"track_map_icon.png"] forState:UIControlStateNormal];
int iId=[[self.imageId objectAtIndex:row] intValue];
NSLog(@"iId=%d",iId);
[trackImageOnMap setTag:iId];
[trackImageOnMap addTarget:self action:@selector(trackImageOnMapButtonTouched:)forControlEvents:UIControlEventTouchDown];
[trackImageOnMap setContentMode:UIViewContentModeScaleToFill];
//[cell setAccessoryView:trackImageOnMap];
[cell addSubview:trackImageOnMap];

Answer 2

您可以创建一个UIImageView并将其分配给UITableViewCell的accessoryView。

UIImageView *imageView = [[[UIImageView alloc] initWithImage:[UIImage imageNamed:@"accessoryIcon"]] autorelease];
cell.accessoryView = imageView;

如果你想要一个配件按钮，它基本上是相同的：

UIButton *button = [UIButton buttonWithType:UIButtonTypeCustom];
[button setImage:[UIImage imageNamed:@"buttonImage"] forState:UIControlStateNormal];
[button addTarget:self action:@selector(someAction:) forControlEvents:UIControlEventTouchUpInside];
button.tag = cell.indexPath;
cell.accessoryView = button;

Answer 3

如果要替换默认类型，可以覆盖UITableViewCell并使用以下代码：

- (void)setAccessoryType:(UITableViewCellAccessoryType)accessoryType
{
    if (accessoryType == UITableViewCellAccessoryDisclosureIndicator)
    {
        self.accessoryView = [[[UIImageView alloc] initWithImage:[UIImage imageNamed:@"YourNewImage.png"]] autorelease];
    }
    else
    {
        [super setAccessoryType:accessoryType];
    }
}
