[英]LogOut from Facebook using childBrowser and PhoneGap in IPhone
[英]PhoneGap/iOS, open ChildBrowser from .shouldStartLoadWithRequest()?
我正在PhoneGap中打包一个移动网站(通过网络),并希望拦截指向PDF的链接并使用ChildBrowser插件打开它们。 它是1 :可能从本机代码触发ChildBrowser
(我已经确定了哪些链接到拦截)和2 : AppDelegate.m
, .shouldStartLoadWithRequest()
是正确的地方吗? 在这种情况下: 3 :如何从本机代码中正确调用ChildBrowser
?
我尝试过这种天真的方法:
return [self exec:@"ChildBrowserCommand.showWebPage",
[url absoluteString]];
但它只导致...'NSInvalidArgumentException', reason: '-[AppDelegate exec:]: unrecognized selector sent to instance
的错误...'NSInvalidArgumentException', reason: '-[AppDelegate exec:]: unrecognized selector sent to instance
。
(PS:我知道这种方法不是理想的做法,但这个项目只定价2天工作)
如果你在插件文件夹中添加( 子浏览器 )插件类,那么你必须使用#import "ChildBrowserViewController.h"
文件, #import "ChildBrowserViewController.h"
例如,你的html文件有以下html / javascript代码,就像这样
window.location="http://xyz.com/magazines/magazines101.pdf";
要在子浏览器中执行此URL,您需要修改包含pdf扩展文件的请求URL的本机shouldStartLoadWithRequest:
方法。
/**
* Start Loading Request
* This is where most of the magic happens... We take the request(s) and process the response.
* From here we can re direct links and other protocalls to different internal methods.
*/
- (BOOL)webView:(UIWebView *)theWebView shouldStartLoadWithRequest:(NSURLRequest *)request navigationType:(UIWebViewNavigationType)navigationType
{
//return [ super webView:theWebView shouldStartLoadWithRequest:request navigationType:navigationType ];
NSURL *url = [request URL];
if([request.URL.absoluteString isEqualToString:@"about:blank"])
return [ super webView:theWebView shouldStartLoadWithRequest:request
navigationType:navigationType ];
if ([[url scheme] isEqualToString:@"gap"]) {
return [ super webView:theWebView shouldStartLoadWithRequest:request
navigationType:navigationType ];
} else {
NSString *urlFormat = [[[url path] componentsSeparatedByString:@"."] lastObject];
if ([urlFormat compare:@"pdf"] == NSOrderedSame) {
[theWebView sizeToFit];
//This code will open pdf extension files (url's) in Child Browser
ChildBrowserViewController* childBrowser = [ [ ChildBrowserViewController alloc ] initWithScale:FALSE ];
childBrowser.modalPresentationStyle = UIModalPresentationFormSheet;
childBrowser.modalTransitionStyle = UIModalTransitionStyleFlipHorizontal;
[super.viewController presentModalViewController:childBrowser animated:YES ];
NSString* urlString=[NSString stringWithFormat:@"%@",[url absoluteString]];
[childBrowser loadURL:urlString];
[childBrowser release];
return NO;
}
else
return [ super webView:theWebView shouldStartLoadWithRequest:request
navigationType:navigationType ];
}
}
谢谢,
MAYUR
任何寻找android等价物的人,将下面的代码放在shouldOverrideUrlLoading中
ChildBrowser childBrowser = new ChildBrowser();
childBrowser.cordova = this;
childBrowser.showWebPage(url, null);
