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 am trying to show the User different Phone Numbers on Apple Watch and he clicks on one than phone call alert should appear. I'll do it like this but the Alert is just dismissed without call action:
NSMutableArray *tempArray = [[NSMutableArray alloc] initWithCapacity:0];
WKExtension *myExt = [WKExtension sharedExtension];
for (NSString *phone in arr) {
NSString *tel = [NSString stringWithFormat:#"tel:%#",phone];
WKAlertAction *act = [WKAlertAction actionWithTitle:tel style:WKAlertActionStyleDefault handler:^(void){
[myExt openSystemURL:[NSURL URLWithString:phone1]];
}];
[tempArray addObject:act];
}
NSString *titleMessage = #"Call";
NSString *textMessage = #"Please select the number you want to call.";
NSString *cancel = #"Cancel";
WKAlertAction *act = [WKAlertAction actionWithTitle:cancel style:WKAlertActionStyleDestructive handler:^(void){
}];
[tempArray addObject:act];
[self presentAlertControllerWithTitle:titleMessage message:textMessage preferredStyle:WKAlertControllerStyleAlert actions:tempArray];
Buttons are shown as expected and the Handler is also called with the correct Phone Number. But it does not openSystemURL. Does somebody know why and how to fix? Thanks!
I think you forgot to add "tel" scheme ,Use below code :
[WKAlertAction actionWithTitle:#"tel" style:WKAlertActionStyleDefault handler:^(void){
[[WKExtension sharedExtension]openSystemURL:[NSURL URLWithString:[NSString stringWithFormat:#"tel:%#",#"YOUR NUMBER"]]];
}];

i am using maps.googleapis.com/maps/api/directions/json? for route plotting in objc . when i plot the line there is a slight change of coordinate , means the pin and the polyline don't intersect . Is there any way to plot with exact points in MKMap.
my code
NSURL *url = [NSURL URLWithString:[NSString stringWithFormat:#"https://maps.googleapis.com/maps/api/directions/json?origin=%f,%f&destination=%f,%f&sensor=false&mode=driving", agentLati, agentLogi, userLati, userLogi]];
..........
if (polyLine !=nil) {
[_route_Map removeOverlay:polyLine];
}
polyLine = [[MKPolyline alloc]init];
// polyLine = [self polylineWithEncodedString:[[[[responseDict objectForKey:#"routes"] objectAtIndex:0]objectForKey:#"overview_polyline"] objectForKey:#"points"]];
polyLine = [self polylineWithEncodedString:[[[[responseDict objectForKey:#"routes"] objectAtIndex:0]objectForKey:#"overview_polyline"] objectForKey:#"points"]];
[_route_Map addOverlay:polyLine];
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'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.
I want to do mock for TnSettings, yes, it works if code by the following method, the problem is that we need to do write mock code for each case, if we only mock once then execute more than one case, then the second will report exception. I use the latest OCMock V2.01.
My question is that why OCMock has such restriction? Or is it my fault not to use it correctly?
Any idea or discussion will be appreciated, thanks in advance.
- (void) testFormattedDistanceValueWithMeters {
mockSettings = [OCMockObject mockForClass:[TnSettings class]];
mockClientModel = [TnClientModel createMockClientModel];
[[[mockClientModel expect] andReturn:mockSettings] settings];
[[[mockSettings expect] andReturn:[NSNumber numberWithInt:0]] preferencesGeneralUnits];
NSNumber *meters = [NSNumber numberWithDouble:0.9];
distance = [NSString formattedDistanceValueWithMeters:meters];
STAssertEqualObjects(distance, #"0.9", #"testformattedEndTimeForTimeInSeconds failed");
//------------- Another case -----------------
mockSettings = [OCMockObject mockForClass:[TnSettings class]];
mockClientModel = [TnClientModel createMockClientModel];
[[[mockClientModel expect] andReturn:mockSettings] settings];
[[[mockSettings expect] andReturn:[NSNumber numberWithInt:0]] preferencesGeneralUnits];
meters = [NSNumber numberWithDouble:100.9];
distance = [NSString formattedDistanceValueWithMeters:meters];
STAssertEqualObjects(distance, #"101", #"testformattedEndTimeForTimeInSeconds failed");
}
Not sure I understand your question or your code fully. I suspect that you stumbled over the difference between expect and stub, though.
Is this what you had in mind?
- (void) testFormattedDistanceValueWithMeters {
mockSettings = [OCMockObject mockForClass:[TnSettings class]];
mockClientModel = [TnClientModel createMockClientModel];
[[[mockClientModel stub] andReturn:mockSettings] settings];
[[[mockSettings stub] andReturn:[NSNumber numberWithInt:0]] preferencesGeneralUnits];
NSNumber *meters = [NSNumber numberWithDouble:0.9];
distance = [NSString formattedDistanceValueWithMeters:meters];
STAssertEqualObjects(distance, #"0.9", #"testformattedEndTimeForTimeInSeconds failed");
meters = [NSNumber numberWithDouble:100.9];
distance = [NSString formattedDistanceValueWithMeters:meters];
STAssertEqualObjects(distance, #"101", #"testformattedEndTimeForTimeInSeconds failed");
}
