如何在Xcode中将上边距添加到我的tableview中？

我试图在表视图的第一个单元格的顶部添加一个图像。如何使表格视图具有上边距？现在，图像刚好与tableview重叠。我正试图让桌面视图稍微降低一点。我不想让它变小或类似的东西。我只想在tableview的顶部添加一个按钮

我不确定我是否理解您的问题，如果您试图在表和视图之间留一个空白，请尝试以下方法：

Swift 3

self.tableView.contentInset = UIEdgeInsets(top: 20,left: 0,bottom: 0,right: 0)

Swift 2

self.tableView.contentInset = UIEdgeInsetsMake(20, 0, 0, 0);

我把这个放在哪里？我对xcode有点陌生。我的viewController？只需从tableViewController类中添加viewDidLoad，因为它会说“找不到成员contentinset”，您可能需要发布一些代码，否则很难判断错误所在。很旧的代码需要重新访问，所以假设您找到了解决方案，但看起来您没有利用其中的“Inset”部分“tableview.contentInset”这是一个UIViewController，您应该从UITableViewController继承它，请尝试在类声明中更改它。我不断收到断点错误。然后它将我指向我的应用程序委托，其中显示我有sigabrt错误，但我甚至没有触碰情节提要。
