Hi,
I am trying to use the camera api for the iphone, however keep getting
navigator.camera [undefined] is not an object. Do you know what the
issue is? Here is the code I am using:
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01//EN"

/* Helper code to resolve anonymous callback functions,
If the function callback can be resolved by name it is returned
unaltered.
If the function is defined in an unknown scope and can't be resolved,
an internal reference to the function is added to the internal map.
Callbacks added to the map are one time use only, they will be deleted
once called.
example 1:
function myCallback(){};
fString = GetFunctionName(myCallback);
- result, the function is defined in the global scope, and will be
returned as is because it can be resolved by name.
example 2:
fString = GetFunctionName(function(){};);
- result, the function is defined in place, so it will be returned
unchanged.
example 3:
function myMethod()
{
var funk = function(){};
fString = GetFunctionName(funk);
}
- result, the function CANNOT be resolved by name, so an internal
reference wrapper is created and returned.

What version of phonegap are you using? Generally the phonegap.js
file name includes the version number, for example phonegap.
0.9.5.js. I have successfully tested this example with iPhone 3G
with iOS 4.1.2 and ipad 2 with latest iOS using PhoneGap 9.5. Also
note that there is an error in the fail callback - the function
parameter is mesage but is accessed as message. That is incorrect in
the docs, I will update it.
