在iOS上使用Child Browser - Cordova打开本地pdf文件

我一直在读书,但我还没有得到解决方案。我正在使用FileTransfer成功下载pdf文件。它位于名为Documents的文件夹中,位置如下所示: / Users / myusername / Library / Application Support / iPhone Simulator / 5.1 / Applications / C62E5802-56A8-48BF-B57C-695801F3C8D6 / HelloWorld.app / Documents / 11.pdf

我正在尝试使用ChildBrowser打开它,到目前为止我没有成功。

要打开的代码是:

cordova.exec("ChildBrowserCommand.showWebPage", path );

当路径是外部的(例如http://www.google.com/)时,它运作良好(域名已列入白名单)。

我尝试过所有这些路径但没有成功:

file:/// Users / myusername / Library / Application Support / iPhone Simulator / 5.1 / Applications / C62E5802-56A8-48BF-B57C-695801F3C8D6 / HelloWorld.app / Documents / 11.pdf

file://// Users / myusername / Library / Application Support / iPhone Simulator / 5.1 / Applications / C62E5802-56A8-48BF-B57C-695801F3C8D6 / HelloWorld.app / www / Documents / 11.pdf

文件:///Documents/11.pdf

我需要做什么才能达到目的?查看上面的应用程序位置,我找不到www文件夹(我假设它已被打包)

这一切都在模拟器,cordova 2.1.0和最新的ChildBrowser中。

我在这里找到了另一个回答我的问题。 link

要提交的文件应该是这样的:

file:///Users/{username}/Library/Application%20Support/iPhone%20Simulator/5.0/Applications/F815A351-44EC-46E8-AD00-A7D775FF9ECC/Documents/11.pdf

提供的文件已下载到应用程序的Documents文件夹中,而不是放在www文件夹中。 得到这样的网址:

fp = entry.fullPath;
urld = "file://" + fp;
//open the file in ChildBrowser
cordova.exec("ChildBrowserCommand.showWebPage", encodeURI(urld) );

我在ChildBrowser中添加了https://github.com/vfr/Reader PDF阅读器。 它非常棒!

当前组件版本:Cordova 2.2.0的子浏览器

编辑ChildBrowserCommand.h:

#import <Cordova/CDVPlugin.h>
#import "ChildBrowserViewController.h"
#import "ReaderDemoController.h"
#import "ReaderViewController.h"
@interface ChildBrowserCommand : CDVPlugin <ChildBrowserDelegate, ReaderViewControllerDelegate>{}

@property (nonatomic, strong) ChildBrowserViewController* childBrowser;
@property (nonatomic, strong) ReaderDemoController* reader;

- (void)showWebPage:(NSMutableArray*)arguments withDict:(NSMutableDictionary*)options;
- (void)onChildLocationChange:(NSString*)newLoc;

@end

在.M文件中 1)@synthesize reader;

2)

- (void)showWebPage:(NSMutableArray*)arguments withDict:(NSMutableDictionary*)options  
{
    NSString* url = (NSString*)[arguments objectAtIndex:0];
    if([url hasSuffix:@".pdf"])
    {
        NSString *phrase = nil; // Document password (for unlocking most encrypted PDF files)
        ReaderDocument *document = [ReaderDocument withDocumentFilePath:url password:phrase];
        ReaderViewController *readerViewController = [[ReaderViewController alloc] initWithReaderDocument:document];'

        readerViewController.delegate = self; // Set the ReaderViewController delegate to self
        readerViewController.modalTransitionStyle = UIModalTransitionStyleCrossDissolve;
        readerViewController.modalPresentationStyle = UIModalPresentationFullScreen;

        [self.viewController presentModalViewController:readerViewController animated:YES];
    }
    else
    {
        if (self.childBrowser == nil) {
#if __has_feature(objc_arc)
            self.childBrowser = [[ChildBrowserViewController alloc] initWithScale:NO];
            NSLog(@"HAS ARC");
#else
            self.childBrowser = [[[ChildBrowserViewController alloc] initWithScale:NO] autorelease];
            NSLog(@"NO ARC");
#endif
            self.childBrowser.delegate = self;
            self.childBrowser.orientationDelegate = self.viewController;
        }
        [self.viewController presentModalViewController:childBrowser animated:YES];
        [self.childBrowser loadURL:url];
    }
}

3)

-(void)dismissReaderViewController:(ReaderViewController *)viewController{
    NSLog(@"The delegate to dismiss pdf reader was called");
   [self.viewController dismissModalViewControllerAnimated:YES];}

4)将所有内容从Reader复制到我们的项目中,添加所需的所有框架

享受。不要忘记为阅读器打开ARC

答案 2 :(得分:2)

childbrowser = ChildBrowser.install();
console.log(location.href);
var strPath = window.location.href;
var path = strPath.substr(0,strPath.lastIndexOf('/')) + "/../../Documents/age.pdf";
console.log(encodeURI(path));
childbrowser.showWebPage(encodeURI(path));

这里代码,打开pdf文件。文件位于本地文件夹Documents

这是一个如何在Phonegap中为我工作的例子

url = "pdf/test.pdf";
function openChildBrowser(url)
{
   try {

   var strPath = window.location.href;
   var path = strPath.substr(0,strPath.lastIndexOf('www')) + "www/"+ url;
   path = path.replace('file:///', '/');
   window.plugins.childBrowser.showWebPage(encodeURI(path));

   }
   catch (err)
   {
    console.log(err);
   }

}
