显示WKInterfaceTable时第一个单元格被隐藏

Question

我有一个WKInterfaceTable，它开始隐藏（因为它正在用我的原始代码从服务器中检索信息），当表被填充时，我只显示它，第一行开始折叠。

在这里，您将拥有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];

}

UPDATE我发现，如果我在发送到主队列的块上填充表，就可以解决问题。

- (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"];
    }

});


}
