iOS开发- 文件共享(利用iTunes导入文件, 并且显示已有文件)

实现过程:

1。在应用程序的Info.plist文件中添加Application supports iTunes file sharing键，并将键值设置为YES。

 

- (void)viewDidLoad {

    [super viewDidLoad];

    _array_FileName=[[NSMutableArray alloc]init];

    _array_FilePath=[[NSMutableArray alloc]init];

    [self getFile];

}

/**

 *  获取NSDocuments文件下的pdf文件

 */

-(void)getFile{

    NSString *DocPath=[NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES) lastObject];

    file_manager=[[NSFileManager alloc]init];

    NSArray *subPaths=[file_manager subpathsAtPath:DocPath];

    for (NSString *path in subPaths) {

        NSArray *arry=[path componentsSeparatedByString:@"."];

        NSString *last=[arry lastObject];

        if ([last isEqualToString:@"pdf"]) {

            [_array_FilePath addObject:[DocPath stringByAppendingPathComponent:path]];

            [_array_FileName addObject:[path lastPathComponent]];

            NSLog(@"filepath:%@  ----- fileName:%@",path,[path lastPathComponent]);

        }

    }

    [_mytableview reloadData];



}
