apple-watch - 显示 WKInterfaceTable 时隐藏第一个单元格

Question

我有一个 WKInterfaceTable 开始隐藏（因为它在我的原始代码中从服务器检索信息），当表格被填满时，我只是显示它并且第一行开始折叠。

这里有 willActivate 代码。

- (void)willActivate {
// This method is called when watch view controller is about to be visible to user
[super willActivate];
[self.myTable setNumberOfRows:10 withRowType:@"MyCell"];
for (int i = 0; i < self.myTable.numberOfRows; i++) {
    MyCell * cell = [self.myTable rowControllerAtIndex:i];
    [cell.myTitle setText:@"My title"];
}

[self.myTable setHidden:NO];

}

更新我发现如果我在发送到主队列的块上填充表，它可以解决问题。

- (void)willActivate {
// This method is called when watch view controller is about to be visible to user
[super willActivate];
[self.myTable setHidden:NO];
dispatch_async(dispatch_get_main_queue(), ^{

    [self.myTable setNumberOfRows:10 withRowType:@"MyCell"];
    for (int i = 0; i < self.myTable.numberOfRows; i++) {
        MyCell * cell = [self.myTable rowControllerAtIndex:i];
        [cell.myTitle setText:@"My title"];
    }

});


}
