ios - Watchkit：动态行中有两个模板的表

Question

如何在 WKInterfaceTable 中实例化两个不同的动态行模板？我只对一个模板使用函数

 [self.stocksTable setNumberOfRows: self.stocksData.count withRowType:@"TableRow"];
 TableRow *row = [self.stocksTable rowControllerAtIndex:i];

问题：如何有两种类型的行？

Answer 1

你想要-[WKInterfaceTable setRowTypes:]：

[self.myTable setRowTypes:@[@"RowType1", @"RowType2"]];
MyRowType1Controller *row1 = [self.myTable rowControllerAtIndex:0];
MyRowType2Controller *row2 = [self.myTable rowControllerAtIndex:1];

Answer 2

基于@dave-delong（正确！）的答案，大多数表将混合行类型，并且数组必须反映这一点。例如，一个带有页眉、4 行信息和一个页脚的表格需要一个看起来像这样的数组：

NSArray *rowTypes = @[@"headerRowType", @"infoRowType", @"infoRowType", @"infoRowType", @"infoRowType", @"footerRowType"];
[self.myTable setRowTypes:rowTypes];

快速解决方案，用于动态细胞计数的情况：

    let notificationRowTypes = Array(repeating: "notificationRow", count: watchNotifications.count)
    let notificationDateRowTypes = Array(repeating: "notificationDateRow", count: watchNotifications.count)
    let rowTypes = mergeArrays(notificationDateRowTypes, notificationRowTypes)
    noficationsTable.setRowTypes(rowTypes)
    updateTableRowsContent()


func mergeArrays<T>(_ arrays:[T] ...) -> [T] {
    return (0..<arrays.map{$0.count}.max()!)
        .flatMap{i in arrays.filter{i<$0.count}.map{$0[i]} }
}

func updateTableRowsContent() {
    let numberOfRows = noficationsTable.numberOfRows
    for index in 0..<numberOfRows {
        switch index % 2 == 0 {
        case true:
            guard let controller = noficationsTable.rowController(at: index) as? NotificationDateRowController else { continue }
            controller.notification = watchNotifications[index / 2]
        case false:
            guard let controller = noficationsTable.rowController(at: index) as? NotificationRowController else { continue }
            controller.notification = watchNotifications[index / 2]
        }
    }
}
