 5 | [iOS QLPreviewController 文件预览](http://www.jianshu.com/p/85562c66648b)
 6 | 
 7 | 官方SDK提供了一个QLPreviewController，使用它就可以让我们的App在iPhone/iPad中直接预览各个文件了。官方的开发文档中说明其支持的文件类型有：
 8 | 
 9 | iWork文档
10 | 微软Office97以上版本的文档
11 | RTF文档
12 | PDF文件
13 | 图片文件
14 | 文本文件和CSV文件
15 | 
16 | ###使用方法
17 | ```
18 | //1.创建
19 | QLPreviewController *previewController = [[QLPreviewController alloc] init];
20 | //2.设置代理
21 | previewController.dataSource = self;
22 | previewController.delegate = self;
23 | //3.实现代理
24 | - (NSInteger)numberOfPreviewItemsInPreviewController:(QLPreviewController *)controller{
25 |    //返回当前预览文件的个数
26 |     return self.filePathArr.count;
27 | }
28 | 
29 | - (id <QLPreviewItem>)previewController:(QLPreviewController *)controller previewItemAtIndex:(NSInteger)index{
30 |     NSURL *url = [NSURL fileURLWithPath:self.filePathArr[index]];
31 |     //返回每一个要预览的文件的地址
32 |     return  url;
33 | }
34 | 
35 | //4.跳转
36 |  [self presentViewController:previewController.dataSource animated:YES completion:nil];
37 | 
38 | ```
39 | 
40 | ###封装
41 | 为了在项目过程中使用方便，作了简单的封装
42 | #### 多文件预览封装
43 | ######用到的类 YWFilePreviewController
44 | ######API
45 | ```
46 | /** 预览多个文件 单个文件时数组传一个 */
47 | - (void)previewFileWithPaths:(NSArray <NSString *>*)filePathArr on:(UIViewController *)vc jump:(YWJumpMode)jump;
48 | 
49 | /** 将要退出 */
50 | - (void)setWillDismissBlock:(void (^)())willDismissBlock;
51 | 
52 | /** 已经退出 */
53 | - (void)setDidDismissBlock:(void (^)())didDismissBlock;
54 | 
55 | /** 将要访问文件中的Url回调  BOOL 是否允许访问*/
56 | - (void)setShouldOpenUrlBlock:(BOOL (^)(NSURL *, id<QLPreviewItem>))shouldOpenUrlBlock;
57 | ```
58 | ######调用
59 | ```
60 | NSArray *filePathArr = @[filePath2,filePath1, filePath3, filePath4, filePath5];
61 |     
62 |     YWFilePreviewController *_filePreview = [[YWFilePreviewController alloc] init];
63 | 
64 |     [_filePreview previewFileWithPaths:filePathArr on:self jump:YWJumpPresentAnimat];
65 | ```
66 | 
67 | #### 单文件快速预览封装
68 | ######用到的类 YWFilePreviewView
69 | ######API
70 | ```
71 | /** 快速预览单个文件 */
72 | + (void)previewFileWithPaths:(NSString *)filePath;
73 | ```
74 | ######调用
75 | ```
76 | [YWFilePreviewView previewFileWithPaths:filePath4];
77 | ```
