vs2017 ios开发中遇到的问题
1. 有时候关闭webview子页面的时候会出错。一般是因为线程的问题
try
{
//有时候在并行编程中,通过ui主线程来处理并不能够奏效,这时候需要通过禁用UI线程,这样就不会出错:
var previous = UIApplication.CheckForIllegalCrossThreadCalls;
UIApplication.CheckForIllegalCrossThreadCalls = false;
mainWebView.ViewWithTag(99).RemoveFromSuperview();
UIApplication.CheckForIllegalCrossThreadCalls = previous;
}
catch (Exception ex)
{
//在主线程更新UI操作
InvokeOnMainThread(() => {
mainWebView.ViewWithTag(99).RemoveFromSuperview();
});
}
2. alert提示框
UIAlertView messageBox = new UIAlertView("提示", "你点击了一个按钮", null, "Close", "OK"); messageBox.Clicked += (caller, buttonArgs) => { Console.Write("qqqqqqqq"); }; messageBox.Show();
