iOS 隐藏QLPreviewController右上角的分享按钮

预览PDF文件的时候，想通过属性隐藏右上角的分享按钮，但是属性里面没有，只能自己想方法隐藏了

.m文件

 

#import "YLPDFPreviewController.h"
#import <QuickLook/QuickLook.h>

@interface YLPDFPreviewController ()<QLPreviewControllerDelegate, QLPreviewControllerDataSource>

@property(nonatomic,strong)QLPreviewController *previewController;

@end

@implementation YLPDFPreviewController

- (void)viewDidLoad {
    [super viewDidLoad];
    [self addChildViewController:self.previewController];
    self.previewController.view.frame = self.view.bounds;
    [self.view addSubview:self.previewController.view];
}

-(QLPreviewController *)previewController{
  if (!_previewController) {
    _previewController = [[QLPreviewController alloc] init];
    _previewController.delegate = self;
    _previewController.dataSource = self;
    [_previewController setCurrentPreviewItemIndex:0];
  }
  return _previewController;
}

#pragma mark -- 文件预览的代理方法：
- (NSInteger)numberOfPreviewItemsInPreviewController:(QLPreviewController *)controller{
  return 1;
}
- (id<QLPreviewItem>)previewController:(QLPreviewController *)controller previewItemAtIndex:(NSInteger)index{
    return _fileURL;
}

- (void)setFileName:(NSString *)fileName {
  _fileName = fileName;
  self.navigationItem.title = _fileName;
}

- (void)setFileURL:(NSURL *)fileURL {
  _fileURL = fileURL;
  [self.previewController reloadData];
}

- (void)previewControllerDidDismiss:(QLPreviewController *)controller{

  NSError * error;
  [NSFileManager.defaultManager removeItemAtURL:_fileURL error:&error];
  NSLog(@"%@",error.description);
  if (self.dismissBlock) {
    self.dismissBlock();
  }
  
}

 .h文件

 

 

@interface YLPDFPreviewController : UIViewController

@property(nonatomic,copy)NSString * fileName;
@property(nonatomic,copy)NSString * filePath;
@property(nonatomic,strong)NSURL *fileURL;
//预览完成回调：
@property(nonatomic,copy)void(^dismissBlock)(void);

@end

 在使用的地方直接push即可:调用代码

 

YLPDFPreviewController *PDFPreviewVC = [[YLPDFPreviewController alloc]init];
PDFPreviewVC.modalPresentationStyle = 0;
PDFPreviewVC.fileName = self.fileName;
PDFPreviewVC.fileURL = filePath;
[self.navigationController pushViewController:PDFPreviewVC animated:YES];
