hi havent found the solution yet in the forum.
i want to call a function i created in the index.html via a objective-c function. As explained in stringByEvaluatingJavaScriptFromString
so the network detection doesnt work for me
the function gets called but no javascript is called in the index.html here is the code i use
- (void)updateReachability:(NSString*)callback
{
NSString* jsCallback = @"navigator.network.updateReachability";
if (callback)
jsCallback = callback;
NSString* status = [[NSString alloc] initWithFormat:@"%@({ hostName: '%@', ipAddress: '%@', remoteHostStatus: %d, internetConnectionStatus: %d, localWiFiConnectionStatus: %d });",
jsCallback,
[[Reachability sharedReachability] hostName],
[[Reachability sharedReachability] address],
[[Reachability sharedReachability] remoteHostStatus],
[[Reachability sharedReachability] internetConnectionStatus],
[[Reachability sharedReachability] localWiFiConnectionStatus]];
[webView stringByEvaluatingJavaScriptFromString:status];
[status release];
}
If i log the status the string i see can be executed in the index.html file, the syntax is ok. but it doesnt get called
if i do alert( etc... it gets called...
need some help pls, because network detection is a kill criteria to publish a app!!!
