我已经在模拟器和iPhone 5S上对此进行了测试
您知道如何实际禁用按钮吗?更喜欢禁用按钮上的用户交互
[self.btnCancel setUserInteractionEnabled:NO];
我发现了问题,而实际上问题不在于按钮 Validate and Save按钮调用对web服务进行异步调用的函数 我使用通知让主线程知道何时收到响应 通知正在后台线程上发回。其影响是取消按钮被实时启用,而不是视觉状态
我修改了代码,以便将通知发送回主线程,现在主线程上的所有内容都会在1秒内更新。我确信它已连接,否则不会变为灰色。@wilkeit ok!然后尝试禁用按钮上的用户交互,就像我在上面的答案中所做的那样:顺便说一句,我更新了我的答案!我已经更新了描述,并从表格后面提供了完整的代码。我还更新了代码以匹配您的建议,但仍然没有成功。我做了一个测试并添加了一个名为IsWorking的属性,我在单击BtnValidate和Save按钮时更改了该值。我在单击btnCancel时检查该值,因为它不匹配,所以停止。但是,按钮再次变为绿色。这可能与它是一个模态序列这一事实有关吗?此外,我尝试使用控制消息传递和点符号,但这两个选项都不起作用。它几乎像是在一条单独的线上。
