这里面包括下载和打开文档的操作:需要先导入《AFNetworking》的框架
第一步:创建一个显示文档的view:ReadViewController
(1).h的代码如下:
@interface ReadViewController : UIViewController -(void)loadOfficeData:(NSString *)officePath; @end
(2).m的代码如下:
@interface ReadViewController () { UIWebView * _dataView; NSString* _urlStr; } @end @implementation ReadViewController - (void)viewDidLoad { [super viewDidLoad]; // Do any additional setup after loading the view. if ([self respondsToSelector:@selector(setAutomaticallyAdjustsScrollViewInsets:)]) { self.automaticallyAdjustsScrollViewInsets = NO; self.modalPresentationCapturesStatusBarAppearance = NO; } if ([self respondsToSelector:@selector(edgesForExtendedLayout)]) { self.edgesForExtendedLayout = UIRectEdgeNone; } self.navigationItem.leftBarButtonItem = [[UIBarButtonItem alloc] initWithTitle:@"返回" style:UIBarButtonItemStylePlain target:self action:@selector(back)]; } - (void)back { [self dismissViewControllerAnimated:YES completion:nil]; }
//仍然下载上面的。m里面 -(void)loadOfficeData:(NSString *)officePath{ _urlStr=officePath; if (!_dataView) { _dataView=[[UIWebView alloc] initWithFrame:CGRectMake(0,0, self.view.frame.size.width, self.view.frame.size.height)]; [self.view addSubview:_dataView]; } _dataView.autoresizingMask=UIViewAutoresizingFlexibleHeight|UIViewAutoresizingFlexibleWidth; NSURL *url = [[NSURL alloc] initWithString:_urlStr]; _dataView.scalesPageToFit = YES; NSURLRequest *requestDoc = [NSURLRequest requestWithURL:url]; [_dataView loadRequest:requestDoc]; }
第二步:创建一个下载和打开文档的工具类:YZFileDownloadAndReadTool
(1)YZFileDownloadAndReadTool.h的代码如下:
@interface YZFileDownloadAndReadTool : NSObject /* 打开文档 */ - (void)openDocument:(NSString *)documentPath; //设置单利 + (YZFileDownloadAndReadTool *)shareManager; @end
(2)YZFileDownloadAndReadTool.m的代码如下:
#import "YZFileDownloadAndReadTool.h" #import "ReaderViewController.h" #import "AFNetworking.h" #import "ReadViewController.h" #define GetFileInAppData(file) [NSHomeDirectory() stringByAppendingPathComponent:[NSString stringWithFormat:@"/Documents/%@",file]] @interface YZFileDownloadAndReadTool ()<ReaderViewControllerDelegate> @end @implementation YZFileDownloadAndReadTool + (YZFileDownloadAndReadTool *)shareManager { static YZFileDownloadAndReadTool *shareManagerInstance = nil; static dispatch_once_t predicate; dispatch_once(&predicate, ^{ shareManagerInstance = [[self alloc] init]; }); return shareManagerInstance; } /** * @author Jakey * * @brief 下载文件 * * @param paramDic 附加post参数 * @param requestURL 请求地址 * @param savedPath 保存 在磁盘的位置 * @param success 下载成功回调 * @param failure 下载失败回调 * @param progress 实时下载进度回调 */ - (void)downloadFileWithOption:(NSDictionary *)paramDic withInferface:(NSString*)requestURL savedPath:(NSString*)savedPath downloadSuccess:(void (^)(AFHTTPRequestOperation *operation, id responseObject))success downloadFailure:(void (^)(AFHTTPRequestOperation *operation, NSError *error))failure progress:(void (^)(float progress))progress { //沙盒路径 //NSString *savedPath = [NSHomeDirectory() stringByAppendingString:@"/Documents/xxx.zip"]; AFHTTPRequestSerializer *serializer = [AFHTTPRequestSerializer serializer]; NSMutableURLRequest *request =[serializer requestWithMethod:@"POST" URLString:requestURL parameters:nil error:nil]; AFHTTPRequestOperation *operation = [[AFHTTPRequestOperation alloc]initWithRequest:request]; [operation setOutputStream:[NSOutputStream outputStreamToFileAtPath:savedPath append:NO]]; [operation setDownloadProgressBlock:^(NSUInteger bytesRead, long long totalBytesRead, long long totalBytesExpectedToRead) { float p = (float)totalBytesRead / totalBytesExpectedToRead; progress(p); NSLog(@"download:%f", (float)totalBytesRead / totalBytesExpectedToRead); }]; [operation setCompletionBlockWithSuccess:^(AFHTTPRequestOperation *operation, id responseObject) { success(operation,responseObject); NSLog(@"下载成功"); } failure:^(AFHTTPRequestOperation *operation, NSError *error) { success(operation,error); NSLog(@"下载失败"); }]; [operation start]; } - (void)downloadDocumentOperation:(NSString *)fileName { NSString *filePath = GetFileInAppData(fileName); NSString *tempFileName = [NSString stringWithFormat:@"%@.bak",fileName]; NSString *tempFilePath = GetFileInAppData(tempFileName); NSLog(@"----savePath----%@", filePath); #warning url 需要修改 [self downloadFileWithOption:nil withInferface:@"http://223.202.51.70/FileServer/DownloadFile/17adc036-24ac-4df8-8a49-90c312c0f300.pdf" savedPath:filePath downloadSuccess:^(AFHTTPRequestOperation *operation, id responseObject) { [[NSFileManager defaultManager] moveItemAtPath:tempFilePath toPath:filePath error:nil]; // [self openDocument:filePath]; [self openHadDownloadDocument:fileName]; } downloadFailure:^(AFHTTPRequestOperation *operation, NSError *error) { } progress:^(float progress) { }]; } /* 打开文档 */ - (void)openDocument:(NSString *)documentPath{ UIWindow *window = [[[UIApplication sharedApplication] delegate] window]; NSString *filePath = GetFileInAppData(documentPath); NSString *documentName = [filePath lastPathComponent]; if (![[NSFileManager defaultManager] fileExistsAtPath:filePath]) { [self downloadDocumentOperation:documentPath]; return; } ReadViewController * readView=[[ReadViewController alloc] init]; UINavigationController *nav = [[UINavigationController alloc] initWithRootViewController:readView]; [window.rootViewController presentViewController:nav animated:YES completion:nil]; readView.navigationItem.title=documentPath; NSString *documentsDirectory = [NSHomeDirectory() stringByAppendingPathComponent:@"Documents"]; NSString* _urlStr=[NSString stringWithFormat:@"%@/%@",documentsDirectory,[documentPath stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding]]; [readView loadOfficeData:_urlStr]; }
第三步:在需要的点击,倒入 YZFileDownloadAndReadTool.h,接着实现
#pragma mark - 点击界面下载pdf - (void)touchesBegan:(NSSet<UITouch *> *)touches withEvent:(UIEvent *)event { // YZFileDownloadAndReadTool *tools = [YZFileDownloadAndReadTool shareManager]; // [tools openDocument:@"01-传感器.pptx"]; [[YZFileDownloadAndReadTool shareManager] openDocument:@"01-传感器.pptx"]; // [tools openDocument:@"button圆角的设置和边框的设置.docx"]; // [tools openDocument:@"沃迪康工作计划安排.xlsx"]; // [tools openDocument:@"ArcGIS for iOS 2.3开发教程-基础版.pdf"]; }
