一: 在app中使用第三放应用(wps 等)打开本地文档。
1. 得到本地文档的路径
NSURL *url = [NSURL fileURLWithPath:localPath];
2.创建文档对象
_documentInteractionController = [UIDocumentInteractionController
interactionControllerWithURL:url];
3.设置代理 (UIDocumentInteractionControllerDelegate)
[_documentInteractionController setDelegate:self];
4. 实现代理方法
- (UIViewController *)documentInteractionControllerViewControllerForPreview:(UIDocumentInteractionController *)controller{
return self;
}
5. 跳转/预览
5.1 跳转: [_documentInteractionController presentOpenInMenuFromRect:CGRectZero inView:self.view animated:YES];
5.2 预览 [_documentInteractionController presentPreviewAnimated:YES];
6. plist文件加节点
<key>CFBundleDocumentTypes</key>
<array>
<dict>
<key>CFBundleTypeName</key>
<string>com.myapp.common-data</string>
<key>LSHandlerRank</key>
<string>Owner</string>
<key>CFBundleTypeRole</key>
<string>Viewer</string>
<key>LSItemContentTypes</key>
<array>
<string>com.microsoft.powerpoint.ppt</string>
<string>public.item</string>
<string>com.microsoft.word.doc</string>
<string>com.adobe.pdf</string>
<string>com.microsoft.excel.xls</string>
<string>public.image</string>
<string>public.content</string>
<string>public.composite-content</string>
<string>public.archive</string>
<string>public.audio</string>
<string>public.movie</string>
<string>public.text</string>
<string>public.data</string>
<string>public.docx</string>
<string>public.doc</string>
</array>
</dict>
</array>
二: 第三方应用回传数据到app
1. 在appdelete 中添加以下方法
- (BOOL)application:(UIApplication *)application openURL:(nonnull NSURL *)url options:(nonnull NSDictionary<NSString *,id> *)options { if (url != nil) { NSString *path = [url absoluteString]; NSMutableString *string = [[NSMutableString alloc] initWithString:path]; if ([path hasPrefix:@"file://"]) { [string replaceOccurrencesOfString:@"file://" withString:@"" options:NSCaseInsensitiveSearch range:NSMakeRange(0, path.length)]; } NSLog(@"获取到的文件路径:%@",string); //使用单例,将获取到的文件路径保存 ShareModel *share=[ShareModel initShareModel]; share.trainFilePath=string; } return YES; }
注意: 只有在第三方中发送或分享至app的文件才能获取到路径 , 在第三方中直接按左上角的返回是不会触发该方法的。
补充: 在第三方中点击返回在app会调用以下方法
applicationWillEnterForeground / applicationDidBecomeActive
