[PhoneGap] Iframes

[Paul G. Hunt]

Hi all.

Phonegap seems to send the user to Safari if there is an iframe in the
app. Past discussions bring up the following fix:

Change this code
-----

// Check to see if the URL request is for the App URL.
// If it is not, then launch using Safari
NSString* urlHost = [url host];
NSString* appHost = [appURL host];
NSRange range = [urlHost rangeOfString:appHost
options:NSCaseInsensitiveSearch];
if (range.location == NSNotFound)
[[UIApplication sharedApplication] openURL:url];

NSString * jsCallBack = nil;
NSArray * parts = [urlString
componentsSeparatedByString:@":"];

-----
To this

// Check to see if the URL request is for the App URL.
// If it is not, then launch using Safari
NSString* urlHost = [url host];
NSString* appHost = [appURL host];
NSRange range = [urlHost rangeOfString:appHost
options:NSCaseInsensitiveSearch];
/*
* We don't have a PhoneGap request, it could be file
or something else
*/
if (range.location == NSNotFound) {
/* [[UIApplication sharedApplication]
openURL:url]; */
}

}

NSString * jsCallBack = nil;
NSArray * parts = [urlString
componentsSeparatedByString:@":"];


--------

How would one do this in 0.9.0? I'm presently developing only for
iPhone OS, if that matters.

Thanks in advance for any insights.

Best,

Paul Hunt

you can disable opening safari on links but as far as I know iframe is
not supported.

Yep, you are right. Bit of a bummer :(

Not actually true. (On the iPhone, at least)You can set the iframe to a
local "blank.html" sourcefile (remember, your Phonegap app can hold
multiple HTML pages in it) and then use Javascript to populate the
iFrame itself, although not from a straight HTTP://.html file, rather
via XHR/JS/App Logic. It's the lack of src=file that causes the browser
to pop up, as the default action URL handler for HTTP requests.

I'm using 0.9.0 and faced the same problem, but solved doing this
litle hack in phonegapDelegate.m
I was using Tab Bars, so when I changed the last else in the code so
it doesn't open Safari, it didn't opened the Tab bar as well... so I
changed this in the shouldStartLoadWithRequest function (added this
else if after the first if)

....

else if ([[url scheme] isEqualToString:@"http"])
{
//NSLog(@"File URL %@", [url description]);
return YES;
}

....

now iframe works and also the tab bar and all javascript calls.

I found this thread from searching on Google. I want to mention that
checking the url inside delegate.m would cause all the other "non-
iframe" links to load within the phonegap app.

I haven't figured out a solution that lets you both load an iframe src
naturally (don't let safari pop-up) and keep regular links clickable
(i.e. open safari.app or ChildBrowser).

Will let you guys know if I find anything interesting. Maybe there's a
way to recognize that a request comes from an explicit link?

[Ricky]

In case anyone is curious, here is the updated snippet.

else if ([url isFileURL] ||

[[url scheme] isEqualToString:@"http"] ||

[[url scheme] isEqualToString:@"https"])
{
if (navigationType == UIWebViewNavigationTypeLinkClicked) {
NSLog(@"PhoneGapDelegate::shouldStartLoadWithRequest: User
clicked. Regular handler. %@", url);
[[UIApplication sharedApplication] openURL:url];
return NO;
} else {
NSLog(@"PhoneGapDelegate::shouldStartLoadWithRequest: Received
file/http/https URL %@", url);
return YES;
}
}

Note: If you use jquery mobile, there's a problem with the iframe
reloading properly with changePage (e.g. embedded youtube videos won't
reply properly when you come back to a cached page). But this should
get iframes to work for now.

I have found another solution to this problem on this thread

https://groups.google.com/group/phonegap/browse_thread/thread/c62e3cd22c9fb0ad/10851673a1819dde?lnk=gst&q=iframe#10851673a1819dde

The solution is to add the domain in PhoneGap.plist under External Hosts.

This was fine by me, cause I know what domains I wan't to allow to be shown in an iframe..

Enjoy

Hi.

I'm looking to solve this problem, and your solution seems fine for my
needs.

Only thing is that I'm sort of a PhoneGap-rookie, and I can't seem to
find the place where I need to add your code.

If you could reveal a little more detail, it would be much
appreciated.

Thanks so far.
