为我的格式,缺乏理解,术语等道歉。我才学习了两天,所以我还是不太明白。我是一名平面设计师,我正在尝试制作一个个人使用的应用程序,它需要一些数据,并让它在视觉上对我更有吸引力。我想创建一天的步数并从健康应用程序中提取此信息。
首先,我已经达到了可以调用 HealthKit StepCount 来显示当天所采取的步骤的程度。只要我使用按钮(IBAction)来获取stepCount数据,然后输出到文本字符串(UILabel),这就是成功的。(例如输出带小数点 66.0 的数字,但一次一步哈!)
现在,我想简单地自动填充“totalSteps UILabel”以显示 stepCount,而不是通过按下按钮来操作它。
我尝试了很多不同的方法,我忘记了我尝试过的内容以及尝试的代码放在哪里,所以任何帮助和/或简短的解释都会很棒!
谢谢你
