    [super viewDidLoad];
    _qlpreviewController = [[QLPreviewController alloc] init];
    _qlpreviewController.view.frame=CGRectMake(100, 100, 250, 500);;
    _qlpreviewController.dataSource = self;
    [_qlpreviewController refreshCurrentPreviewItem];
    [self addChildViewController:_qlpreviewController];
    [self.view addSubview:_qlpreviewController.view];
}
 
#pragma mark - qlpreViewdataSource
- (NSInteger)numberOfPreviewItemsInPreviewController:(QLPreviewController *)controller {
    return 1;
}
 
- (id <QLPreviewItem>)previewController:(QLPreviewController *)controller previewItemAtIndex:(NSInteger)index
{
    // 获取文件路径, 此处可以读取excle docx PDF等格式
    NSString *filePath = [[NSBundle mainBundle] pathForResource:@"demoForWord" ofType:@"docx"];
    return [NSURL fileURLWithPath:filePath];
}
 
- (void)didReceiveMemoryWarning {
    [super didReceiveMemoryWarning];
    // Dispose of any resources that can be recreated.
}
 
 
@end
