今天的扩展iOS10显示更多/更少 [英] Today's extension iOS10 Show More/Less

问题描述

已更新今天iOS 10的扩展名
实现委托方法：

Had updated the today's extension for iOS 10 implement the delegate method:

-(void)widgetActiveDisplayModeDidChange:(NCWidgetDisplayMode)activeDisplayMode withMaximumSize:(CGSize)maxSize
{
    if (activeDisplayMode == NCWidgetDisplayModeCompact){
        [UIView animateWithDuration:0.25 animations:^{
            self.preferredContentSize = maxSize;
            [self.view layoutIfNeeded];
        }];
    }
    else if (activeDisplayMode == NCWidgetDisplayModeExpanded){
        newHeight = [self getNewWidgetHeight];
        [UIView animateWithDuration:0.25 animations:^{
            self.preferredContentSize = CGSizeMake(0, newHeight);
            [self.view layoutIfNeeded];
        }];
    }
}

一切正常。但是如果我将小部件保持在紧凑模式（显示更多选项）并且如果我重新运行/重新打开小部件屏幕，并且如果我点击显示更多按钮，即使触发委托方法也没有任何反应。我应该按2次显示更多/更少，直到小部件开始扩展。
我也收到这个错误：没有活动的动画块！

everything work fine. But if I leave the widget in compact mode (with show more option available) and if i rerun/reopen the widget screen and if i tapped on Show More button nothing happens even if the delegate method is triggered. I should press 2 time show more/less until widget starts expanding. I also receive this error:No active animation block!

推荐答案

我发现了这个问题。

我编辑了 self.preferredContentSize 即使小部件在紧凑模式。每次更新 preferredContentSize 时，如果 widgetActiveDisplayMode 是 NCWidgetDisplayModeExpanded

I had edited the self.preferredContentSize even if the widget was in the compact mode.Just check every time when you update the preferredContentSize if widgetActiveDisplayMode is NCWidgetDisplayModeExpanded
