iOS-实现两个APP之间共享文件(从一个APP拷贝文件至另一个APP)

在项目Info.plist文件中添加如图所示字段(红色框框里是表示所有文件类型都可拷贝)

具体文件类型参考:

Apple documentation

到这一步还没完成:

文件拷贝到咱们App了,咱们需要处理一下(要么存本地,要么直接预览)我的处理是存本地.上代码:

- (BOOL)application:(UIApplication *)app openURL:(NSURL *)url options:(NSDictionary<NSString*, id> *)options
{
    NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
    NSString *documentsDirectory = [paths lastObject];
    if (url != nil) {
        NSString *path = [url absoluteString];
        path = [path stringByRemovingPercentEncoding];
        NSMutableString *string = [[NSMutableString alloc] initWithString:path];
        if ([path hasPrefix:@"file:///private"]) {
            [string replaceOccurrencesOfString:@"file:///private" withString:@"" options:NSCaseInsensitiveSearch  range:NSMakeRange(0, path.length)];
        }
        NSArray *tempArray = [string componentsSeparatedByString:@"/"];
        NSString *fileName = tempArray.lastObject;
        NSString *sourceName = options[@"UIApplicationOpenURLOptionsSourceApplicationKey"];
        
        NSFileManager *fileManager = [NSFileManager defaultManager];
        NSString *filePath = [documentsDirectory stringByAppendingPathComponent:[NSString stringWithFormat:@"%@%@",sourceName,fileName]];
        if ([fileManager fileExistsAtPath:filePath]) {
            NSLog(@"文件已存在");
            [SVProgressHUD showErrorWithStatus:@"文件已存在"];
            return YES;
        }
        [MRTools creatFilePathInManager:sourceName];
        BOOL isSuccess = [fileManager copyItemAtPath:string toPath:filePath error:nil];
        if (isSuccess == YES) {
            NSLog(@"拷贝成功");
            [SVProgressHUD showSuccessWithStatus:@"文件拷贝成功"];
        } else {
            NSLog(@"拷贝失败");
            [SVProgressHUD showErrorWithStatus:@"文件拷贝失败"];
        }
    }
    NSLog(@"application:openURL:options:");
    return  YES;
}
