UIDocumentInteractionController

初始化對象

網(wǎng)上有資料說要用這個屬性要用retain,我也不知道為啥........

實現(xiàn)的代理方法

源碼:

1.引入?yún)f(xié)議<UIDocumentInteractionControllerDelegate>

2.初始化,簽代理

_doc = [UIDocumentInteractionController interactionControllerWithURL:[NSURL fileURLWithPath:filePath]];

?_doc.delegate = self;//設置代理

?[self.doc presentPreviewAnimated:YES];?

presentPreviewAnimated:YES,彈出預覽窗口

presentOptionsMenuFromRect:inView:animated;不彈出預覽窗口,直接彈出菜單(還有很多方法)

3.實現(xiàn)代理方法

#pragma mark -------------documentDelegate---------

- (UIViewController *)documentInteractionControllerViewControllerForPreview:(UIDocumentInteractionController *)controller {

? ? return self;

}

- (UIView *)documentInteractionControllerViewForPreview:(UIDocumentInteractionController *)controller {

? ? return self.view;

}

- (CGRect)documentInteractionControllerRectForPreview:(UIDocumentInteractionController *)controller {

? ? return? self.view.frame;

}
