从应用程序内将捆绑的PDF发送到iBooks [英] Send bundled PDF to iBooks from within app

问题描述

我正在使用下面的代码附加到按钮上，以尝试在iBooks中打开PDF文件，但是当我单击按钮时没有任何反应.该方法肯定被调用.

I'm using the following code attached to a button, to attempt to open a PDF file in iBooks, but nothing's happening when I click the button. The method's definitely being called.

- (IBAction)openDocs
{
    NSURL *url = [NSURL fileURLWithPath:@"MS.pdf"];
    UIDocumentInteractionController *docController = [[UIDocumentInteractionController alloc] init];

    docController = [UIDocumentInteractionController interactionControllerWithURL:url];
    docController.delegate = self;

    BOOL isValid = [docController presentOpenInMenuFromRect:CGRectZero inView:self.view animated:YES];
}

我已经将类本身声明为相关的委托，并且由于文档说没有必需的委托方法，所以我已经完成了所有事情.当我点击按钮时什么也没有发生，而我正在尝试找出我所缺少的东西–任何帮助将不胜感激！

I've declared the class itself as the relevant delegate, and since the documentation says there are no required delegate methods, that's all I've done. Nothing's happening when I tap the button, and I'm trying to figure out what I'm missing – any help is greatly appreciated!

推荐答案

如果捆绑包中包含MS.pdf，则需要像这样获取完整路径:

If MS.pdf is in your bundle then you need to get the full path like so:

NSString *path = [[NSBundle mainBundle] pathForResource:@"MS" ofType:@"pdf"];
NSURL *url = [NSURL fileURLWithPath:path];
