iphone - 如何在表格 View 上添加按钮作为附件？

Question

所以，我有这段代码

UIButton *accessoryButton = [[UIButton alloc] init]; 

UIImage *accImage = [UIImage imageNamed:@"ShareAccButton.png"];

[accessoryButton setImage:accImage forState: UIControlStateNormal];

UIView *accView = [[UIView alloc] initWithFrame: CGRectMake(0, 0, 40, 15)];
[accView addSubview:accessoryButton];

cell.accessoryView = accView;

在此，我尝试将按钮作为表格 View 单元格的附件。这行不通，我想知道如何才能成功做到这一点。另外，我怎样才能将这些按钮连接到功能？

我猜你错过了按钮的框架。只需用一个框架初始化按钮。 正如 jamihash 所说，您可以直接将按钮分配为单元格的 accessoryView。我希望下面的代码可以工作。

UIButton *accessoryButton = [[UIButton alloc] initWithFrame:CGRectMake(0, 0, 20, 20)]; 
UIImage *accImage = [UIImage imageNamed:@"ShareAccButton"];
[accessoryButton setImage:accImage forState: UIControlStateNormal];
[accessoryButton addTarget:self action:@selector(yourMethodName) forControlEvents:UIControlEventTouchUpInside];
[cell setAccessoryView:accessoryButton];
