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;
}

*/
- (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"];
