我正在用Xamarin構建我的第一個應用程序。我創建了一個名爲reord_overlay的UIView。我想將它設置爲viewDidLoad中後隱藏：如何設置UIView隱藏在Xamarin中
record_overlay.Hidden = true;
我得到的是有關
../VoYo/iOS/ViewController.designer.cs(27,27): Error CS0102: The type `VoYo.iOS.ViewController' already contains a definition for `recording' (CS0102) (VoYo.iOS)
錯誤我怎樣才能視圖設置爲隱藏？
錯誤說，這是在我的ViewController.designer.cs文件：
// WARNING
//
// This file has been generated automatically by Xamarin Studio from the outlets and
// actions declared in your storyboard file.
// Manual changes to this file will not be maintained.
//
using Foundation;
using System;
using System.CodeDom.Compiler;
using UIKit;
namespace VoYo.iOS
{
[Register ("ViewController")]
partial class ViewController
{
[Outlet]
UIKit.UIButton Button { get; set; }
[Outlet]
[GeneratedCode ("iOS Designer", "1.0")]
UIView record_overlay { get; set; }
[Outlet]
[GeneratedCode ("iOS Designer", "1.0")]
UIActivityIndicatorView recording { get; set; }
[Outlet]
[GeneratedCode ("iOS Designer", "1.0")]
UIActivityIndicatorView recording { get; set; }
[Outlet]
[GeneratedCode ("iOS Designer", "1.0")]
UITextView Voice { get; set; }
void ReleaseDesignerOutlets()
{
if (record_overlay != null) {
record_overlay.Dispose();
record_overlay = null;
}
if (recording != null) {
recording.Dispose();
recording = null;
}
if (recording != null) {
recording.Dispose();
recording = null;
}
if (Voice != null) {
Voice.Dispose();
Voice = null;
}
}
}
}
我的代碼
using System;
using UIKit;
namespace VoYo.iOS
{
public partial class ViewController : UIViewController
{
//int count = 1;
public ViewController (IntPtr handle) : base (handle)
{
}
public override void ViewDidLoad()
{
base.ViewDidLoad();
// Code to start the Xamarin Test Cloud Agent
#if ENABLE_TEST_CLOUD
Xamarin.Calabash.Start();
#endif
// Perform any additional setup after loading the view, typically from a nib.
Button.AccessibilityIdentifier = "myButton";

你得到的錯誤與「隱藏=真」無關。這聽起來像你有一個控制聲明瞭兩次，無論是在你的代碼背後，還是在你的UI（storyboard或xib）中。 – Jason
你能用更多的代碼編輯你的問題嗎？ –
我只在添加該行時出現錯誤。否則，應用程序將運行在我的iPhone上。我認爲你可能是正確的，導致多重聲明。我試圖找出更改隱藏屬性的正確語法。 –
