i was using http://maps.google.com/maps?output=dir&saddr=%#&daddr=%# api for the step based route plotting . Till the last week i got the response in correct manner . But now the response is only null . Can anyone faced the same issue . Apple map is not plotting correctly in india . when we plot google map/direction api the step is not proper in MKMapkit. Is there any other way to have an accurate map in ObjectiveC
my code is below
NSString* saddr = [NSString stringWithFormat:#"%f,%f", f.latitude, f.longitude];
NSString* daddr = [NSString stringWithFormat:#"%f,%f", t.latitude, t.longitude];
NSString* apiUrlStr = [NSString stringWithFormat:#"http://maps.google.com/maps?output=dir&saddr=%#&daddr=%#", saddr, daddr];
NSURL* apiUrl = [NSURL URLWithString:apiUrlStr];
NSLog(#"api url: %#", apiUrl);
NSError* error = nil;
NSString *apiResponse = [NSString stringWithContentsOfURL:apiUrl encoding:NSASCIIStringEncoding error:&error];
NSLog(#"%#",apiResponse);
I'm having a very strange problem with my Google Maps implementation. I am getting back an array from a REST service that gives me lat/lng and I am in turn using that information to put markers on the map and implement functionality.
That part works fine, it's when it comes to taking the markers output on the page and getting their bounds and zooming the map to them that I get to the problem. I have read several solutions and I have attempted implementing them to the best of my ability.
Here's my implementation:
// Reset the maps bounds
MapView.bounds = new google.maps.LatLngBounds(null);
// Get the new map bounds
for (var i=0, j=MapView.markers.length; i<j; i++){
var marker = MapView.markers[i],
lat = marker.position.lat(),
lng = marker.position.lng(),
latlng = new google.maps.LatLng(lat, lng);
MapView.bounds.extend(latlng);
};
// Set the map bounds to the new bounds
MapView.map.fitBounds(MapView.bounds);

Then I used those bounds to create a poly line to try and find out where the problem was, and the wierd part is even that is wrong, but the map isn't even zooming/panning to THOSE bounds.
Code for poly line:
var ne = MapView.bounds.getNorthEast();
var sw = MapView.bounds.getSouthWest();
var boundingBoxPoints = [
ne, new google.maps.LatLng(ne.lat(), sw.lng()),
sw, new google.maps.LatLng(sw.lat(), ne.lng()), ne
];
var boundingBox = new google.maps.Polyline({
path: boundingBoxPoints,
strokeColor: '#FF0000',
strokeOpacity: 1.0,
strokeWeight: 2
});
boundingBox.setMap(MapView.map);
And a picture of the result (this is as the map loads, un-altered):
It will either load like that (if I'm lucky) or load with most of the trips out of the top of the map with only a couple showing and most of the map canvas gray.
I am a total loss right now, could somebody please point me in the right direction?
I need re-encoding a video file from photo library for web site service.
I tried below code but it has occurred error like 'video composition must have composition instructions'.
(code)
AVAsset *anAsset = [[AVURLAsset alloc] initWithURL:videoFileUrl options:nil];
NSArray *compatiblePresets = [AVAssetExportSession exportPresetsCompatibleWithAsset:anAsset];
if ([compatiblePresets containsObject:AVAssetExportPresetMediumQuality]) {
self.exportSession = [[AVAssetExportSession alloc]
initWithAsset:anAsset presetName:AVAssetExportPresetPassthrough];
AVMutableComposition* mixComposition = [[AVMutableComposition alloc] init];
AVMutableCompositionTrack *firstTrack = [mixComposition addMutableTrackWithMediaType:AVMediaTypeVideo preferredTrackID:kCMPersistentTrackID_Invalid];
[firstTrack insertTimeRange:CMTimeRangeMake(kCMTimeZero, anAsset.duration) ofTrack:[[anAsset tracksWithMediaType:AVMediaTypeVideo] objectAtIndex:0] atTime:kCMTimeZero error:nil];
AVMutableVideoCompositionLayerInstruction *FirstlayerInstruction = [AVMutableVideoCompositionLayerInstruction videoCompositionLayerInstructionWithAssetTrack:firstTrack];
AVMutableVideoCompositionInstruction * MainInstruction = [AVMutableVideoCompositionInstruction videoCompositionInstruction];
MainInstruction.layerInstructions = [NSArray arrayWithObjects:FirstlayerInstruction,nil];
AVMutableVideoComposition *MainCompositionInst = [AVMutableVideoComposition videoComposition];
MainCompositionInst.frameDuration = CMTimeMake(1, 30); // bit rate
MainCompositionInst.renderSize = CGSizeMake(640, 480); // frame rate
[self.exportSession setVideoComposition:MainCompositionInst];
NSURL *furl = [NSURL fileURLWithPath:self.tmpVideoPath];
self.exportSession.outputURL = furl;
self.exportSession.outputFileType = AVFileTypeQuickTimeMovie;
CMTime start = CMTimeMakeWithSeconds(self.startTime, anAsset.duration.timescale);
CMTime duration = CMTimeMakeWithSeconds(self.stopTime-self.startTime, anAsset.duration.timescale);
CMTimeRange range = CMTimeRangeMake(start, duration);
self.exportSession.timeRange = range;
self.trimBtn.hidden = YES;
self.myActivityIndicator.hidden = NO;
[self.myActivityIndicator startAnimating];
[self.exportSession exportAsynchronouslyWithCompletionHandler:^{
switch ([self.exportSession status]) {
case AVAssetExportSessionStatusFailed:
NSLog(#"Export failed: %#", [[self.exportSession error] localizedDescription]);
break;
case AVAssetExportSessionStatusCancelled:
NSLog(#"Export canceled");
break;
default:
NSLog(#"NONE");
dispatch_async(dispatch_get_main_queue(), ^{
[self.myActivityIndicator stopAnimating];
self.myActivityIndicator.hidden = YES;
self.trimBtn.hidden = NO;
[self playMovie:self.tmpVideoPath];
});
break;
}
}];
}
}
without the changing frame rate and bit rate, it works perfectly.
Please give me any advise.
Thanks.
Framerate I'm still looking for, but bitrate has been solved by this drop in replacement for AVAssetExportSession: https://github.com/rs/SDAVAssetExportSession
Not sure but some things to look at. Unfortunatley the error messages dont tell you much in these cases in AVFoundation.
In general, I would make things simple and slowly add functionality.To start, make sure all layers start at zero and then end at the final duration. Do the same for the main composition. Invalid times may give you an error like this. For your instruction, make sure that it starts at the same time and ends at the same time too.
I want to draw a line on ios map using overlayer. I have one code for draw a line on map. But it is not working for me. Can any one help me.
MKCoordinateSpan span;
span.latitudeDelta=.03;
span.longitudeDelta=.03;
MKCoordinateRegion region;
region.span=span;
region.center=CLLocationCoordinate2DMake(39.046259, -76.851195);
[_myMapView setRegion:region animated:YES];
[_myMapView regionThatFits:region];
UITapGestureRecognizer *singleTap = [[UITapGestureRecognizer alloc] initWithTarget:self action:#selector(singleTapWebView:)];
singleTap.numberOfTapsRequired = 1;
singleTap.delegate = self;
[self.myMapView addGestureRecognizer:singleTap];
[singleTap release];
CLLocationCoordinate2D commuterLotCoords[5]=
{
CLLocationCoordinate2DMake(39.036399,-76.872208)
};
MKPolygon *commuterParkingPolygon=[MKPolygon polygonWithCoordinates:commuterLotCoords count:5];
[_myMapView addOverlay:commuterParkingPolygon];
In this above code we can change the end point from this line"CLLocationCoordinate2DMake(39.036399,-76.872208)" But in always the start point is
lat 0.000003, long 0.000000. how can i change the start pint. Could any one help me to solve this issue.
I'm trying to get the temp and weather data for my app based on the latitude and longitude location...
How can I get this to work?
NSURL *jsonurl = [NSURL URLWithString:#"http://www.myweather2.com/developer/forecast.ashx?uac=(API-KEY)&output=json&query=",placemark.location,#"&temp_unit=f"];
NSString *jsonStr = [NSString stringWithFormat:#"http://www.myweather2.com/developer/forecast.ashx?uac=(API-KEY)&output=json&query=%#&temp_unit=f", placemark.location];
NSURL *jsonurl = [NSURL URLWithString:jsonStr];
This assumes that the value for placemark.location is an NSString that only contains valid URL characters.
