Show points and routes with Google Maps in iOS

[JosepM]

Hi,

Any experiences about how in iOS show routes and points into a Google Map?
Attach some images to show what I trying.

Also I guess that using the GPS location, center a map and show points of interest or marks. Using the GoogleMap kit I be able of center a map into a stack but with iOS I can't.

Thanks in advance.

Salut,

I found that with the Google Maps API V3 I can show that I need.

iphoneControlDo id, "load", baseUrl, htmlText
Loads as page consisting of the given htmlText with the given baseUrl (wraps the loadHtmlString method of UIWebView).

Locally I can read from my database the stored marks and prepare the HTML, then load into the Browser.

In htmlText I put my HTML code, and the URL in baseURL.

But now how can I handle the click over a mark into the map to go to one card of the stack? Any idea if is posible?

Salut,
Josep

it's probably something with "iphoneControlGet". I'm not doing iOS dev, so can't say what parameter it'd be, sorry.

The way I've done work with a web view in iOS before and interacting back with the code is by catching the "browserLoadRequest".

(You also need to make sure to set: iphoneControlSet sBrowserId, "delayRequests", "true")

This way you can, say, create a fake URL that you access that has some unique identifying feature about it which you can then parse and intercept. For example, in the code, create a link associated with the pin that goes to http : / / example . com/?myUniqueCode=43.28271,-71.72532

Then, in LiveCode card script:

Code: Select all

on browserLoadRequest pUrl, pReason
    if pUrl contains "?myUniqueCode=" then
        put char offset("?myUniqueCode=",14) to -1 of pUrl into pCode
        -- Do something with pCode
    else
        pass browserLoadRequest
    end if
end browserLoadRequest

Hi,

Many thanks, is just that I need. So in this way you can trap each load request before this will be completed, from the marks or whatever, isn't?
