【问题描述】：

我正在尝试设置单元格的附件视图，即UIButton。但是没有显示出来。

这里是代码

UIButton *accessory = [UIButton buttonWithType:UIButtonTypeCustom];
[accessory setImage:[UIImage imageNamed:@"plus.png"] forState:UIControlStateNormal];
[cell setAccessoryView:accessory];

【问题讨论】：

试试 [cell.contentView 附件];并根据需要定位配件。

【参考方案1】：

调用[accessory sizeToFit];根据图片调整大小。

【参考方案2】：

你需要像这样为这个配件设置一个框架

UIButton *accessory = [UIButton buttonWithType:UIButtonTypeCustom];
[accessory setImage:[UIImage imageNamed:@"plus.png"] forState:UIControlStateNormal];
//Set the accessory frame
accessory.frame = CGRectMake(0, 0, 100, 100);

【参考方案3】：

UIView* accessoryView = [[UIView alloc] initWithFrame:CGRectMake(0, 0, 24, 50)];
UIImageView* accessoryViewImage = [[UIImageView alloc] initWithImage:[UIImage imageNamed:@"arrow.png"]];
accessoryViewImage.center = CGPointMake(12, 25);
[accessoryView addSubview:accessoryViewImage];
[cell setAccessoryView:accessoryView];
[accessoryViewImage release];
[accessoryView release];

就这样吧。
