presentOpenInMenuFromRect 的未定义 self.view

Question

我正在尝试将“presentOpenInMenuFromRect”功能添加到 Rhomobile。但是，我无法引用当前视图。

Rhomobile 函数（### 标记我的补充）：

- (void)openDocInteractCommand:(NSString*)url {
if (NSClassFromString(@"UIDocumentInteractionController")) {
    NSURL *fileURL = [NSURL fileURLWithPath:url];

    UIDocumentInteractionController* docController = [UIDocumentInteractionController interactionControllerWithURL:fileURL];

    docController.delegate = self;//[AppManager instance];

    BOOL result = [docController presentPreviewAnimated:YES];

    if (!result) {
      ###
        BOOL isValid = [docController presentOpenInMenuFromRect:CGRectZero inView:self.view animated:YES];
      ###
    }    
}
}

基本上，如果预览失败，我想打开“打开方式”菜单，因为我正在尝试打开一个 .KMZ（Google 地球 KML 文件）并且它不能预览。

谢谢，

尼克，

Answer 1

这是解决我问题的代码：

  - (void)openDocInteractCommand:(NSString*)url { // inView:(UIView*)view
if (NSClassFromString(@"UIDocumentInteractionController")) {
    NSURL *fileURL = [NSURL fileURLWithPath:url];

    UIDocumentInteractionController* docController = [UIDocumentInteractionController interactionControllerWithURL:fileURL];

    docController.delegate = self;//[AppManager instance];

    BOOL result = [docController presentPreviewAnimated:YES];

    if (!result) {
        [docController retain];
        CGPoint centerPoint = [Rhodes sharedInstance].window.center;
        CGRect centerRec = CGRectMake(centerPoint.x, centerPoint.y, 0, 0);
        BOOL isValid = [docController presentOpenInMenuFromRect:centerRec inView:[Rhodes sharedInstance].window animated:YES];
    }
}
}

- (void)documentInteractionControllerDidEndPreview:(UIDocumentInteractionController *)docController
{
[docController autorelease];
}

AppManager 类继承自 NSObject 而不是 UIViewController - 为什么它会有一个名为 view 的属性？您必须找到另一种方式来呈现您的视图或视图控制器（可能使用应用程序的主窗口）。
