iOS中加载word以及各类文档

最近需求中有加载文档类要求，发现苹果提供 QLPreviewController 可以很方便的加载这些内容，但是 QLPreviewController 对于导航条好像不能做太多操作，我们可以新建一个 viewController 并把 QLPreviewController 添加上，这样可以方便自己自定义很多内容,具体代码如下

#import <UIKit/UIKit.h>

NS_ASSUME_NONNULL_BEGIN

@interface BankQlLoadViewController : UIViewController

@property (nonatomic,copy)  NSString *pathStr;
@property (nonatomic, copy) NSString *pathTitle;

@end

NS_ASSUME_NONNULL_END

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

@interface BankQlLoadViewController ()<QLPreviewControllerDataSource>

@end

@implementation BankQlLoadViewController

- (void)viewDidLoad {
    [super viewDidLoad];
    self.view.backgroundColor = [UIColor whiteColor];
    self.navigationItem.title = self.pathTitle;
    [self configViews];
}
- (void)viewWillAppear:(BOOL)animated {
    [super viewWillAppear:animated];

    [self.navigationController setNavigationBarHidden:NO animated:YES];
    
}

- (void)viewWillDisappear:(BOOL)animated {
    [super viewWillDisappear:animated];

    [self.navigationController setNavigationBarHidden:YES animated:YES];
}
- (void)configViews{
    // 将QLPreviewControler添加到本控制器上
    QLPreviewController *QLController = [[QLPreviewController alloc] init];
    QLController.dataSource = self;
    [self addChildViewController:QLController];
    [QLController didMoveToParentViewController:self];
    [self.view addSubview:QLController.view];
    QLController.view.frame = CGRectMake(0,64, self.view.frame.size.width, self.view.frame.size.height-64);
}

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

- (id<QLPreviewItem>)previewController:(QLPreviewController *)controller previewItemAtIndex:(NSInteger)index{
    NSURL *url = [NSURL fileURLWithPath:self.pathStr];
    return url;
}

@end

使用还是比较简单方便的，我是直接加载的本地文件。
