1、想要使用此功能首先要在工程內加入框架

QuickLook.framework

2、在你需要展示的界面加入頭文件

#import <QuickLook/QuickLook.h>

3、實例化

    QLPreviewController *myQlPreViewController = [[QLPreviewController alloc]init];
    myQlPreViewController.delegate =self;
    myQlPreViewController.dataSource =self;
    [myQlPreViewController setCurrentPreviewItemIndex:0];
    //此處可以帶導航欄跳轉、也可以不帶導航欄跳轉、也可以拿到View進行Add
    [self.navigationController pushViewController:myQlPreViewController animated:YES];

4、代理方法

#pragma mark - QLPreviewController代理
- (NSInteger)numberOfPreviewItemsInPreviewController:(QLPreviewController *)controller
{
    return 1;
}

- (id<QLPreviewItem>)previewController:(QLPreviewController *)controller previewItemAtIndex:(NSInteger)index
{

    NSString* path = [[NSBundle mainBundle] pathForResource:arr[IndeX] ofType:nil];
    return [NSURL fileURLWithPath:path];
}

- (void)previewControllerDidDismiss:(QLPreviewController *)controller
{
    NSLog(@"預覽界面已經消失");
}

//文件內部鏈接點擊不進行外部跳轉
- (BOOL)previewController:(QLPreviewController *)controller shouldOpenURL:(NSURL *)url forPreviewItem:(id <QLPreviewItem>)item
{
    return NO;
}
