Unable to detect ibeacon on iphone 6 - ios

Hi i have below code which works fine on iPod touch 5, but same code is not working on iPhone 6, i done research on same issue but i have not found anything useful. both devices have latest iOS.
Both devices have iOS 8

I suspect you are having authorization issues on your iPhone. Set a breakpoint or add NSLog statements to make sure this line is getting called:
[self.locationManager requestAlwaysAuthorization];
Do you get prompted? If not, uninstall and reinstall.
Also, check in setting that Bluetooth and Location services are enabled on the phone, and check settings on your app to see that location services are actually enabled for it.

You need to set one of
NSLocationAlwaysUsageDescription
or
NSLocationWhenInUseUsageDescription when requesting location updates (even with iBeacons).
If you don't, in iOS 8, this will fail silently.

Inconsistent behaviour by proximity API - iOS iBeacon

I am converting an iOS device into iBeacon and then using core location' ranging API to detect beacon' proximity. Now, this works but I see an unpredictable behaviour where sometimes at a defined distance (say 10 meters away) I see No Beacon sometimes Far Beacon and some times Near Beacon.
Is there a way to make this behaviour more consistent?
- (void)viewDidLoad {
[super viewDidLoad];
self.beaconSwitch.on = NO;
self.beaconView.backgroundColor = [UIColor clearColor];
self.peripheralManager = [[CBPeripheralManager alloc] initWithDelegate:self queue:nil];
BeaconRegion *beaconRegion = [[BeaconRegion alloc] init];
self.beaconRegion = [[CLBeaconRegion alloc] initWithProximityUUID:beaconRegion.uuid major:[beaconRegion.major shortValue] minor:[beaconRegion.minor shortValue] identifier:beaconIdentifier];
}
- (void)viewWillDisappear:(BOOL)animated {
[super viewWillDisappear:animated];
[self.peripheralManager stopAdvertising];
}

}
- (IBAction)beaconSwitchPressed:(id)sender {
if (self.beaconSwitch.on == true) {
self.beaconView.beaconState = BNBeaconStateBroadcasting;
NSDictionary *data = [self.beaconRegion peripheralDataWithMeasuredPower:nil];
[self.peripheralManager startAdvertising:data];
} else {
self.beaconView.beaconState = BNBeaconStateStop;
[self.peripheralManager stopAdvertising];
}
}
Here is how I am converting my iOS device into a beacon:

[self talkToServer];
} else {

message = #"Ignoring server call trigger!";
}
}
}
break;
case CLProximityFar:{
title = #"Far Beacon";
message = #"You are standing far from video wall!";
}
break;
default:
break;
}
self.titleLabel.text = title;
self.messageLabel.text = message;
}
- (void)locationManager:(CLLocationManager *)manager didDetermineState:(CLRegionState)state forRegion:(CLRegion *)region {
if (state == CLRegionStateInside) {
NSLog(#"Starting Ranging");
[self.locationManager startRangingBeaconsInRegion:self.beaconRegion];
}
}
- (void)locationManager:(CLLocationManager *)manager didChangeAuthorizationStatus:(CLAuthorizationStatus)status {
if (![CLLocationManager locationServicesEnabled]) {
NSLog(#"Location Service Not Enabled");
}
if ([CLLocationManager authorizationStatus] != kCLAuthorizationStatusAuthorizedAlways) {
NSLog(#"Location Service Not Authorized");
}
}
For now, I have put a condition on received signal strength indicator (rssi) value and accepting anything > -60 in Near proximity to make the distance little more predictable. So, within Nearby proximity also I trigger my action if rssi > -60.

iOS Map Marker and current location not showing

I have a MapViewController that imports SWRevealViewController and I honestly didn't code this lines below. I tried to run the app but unfortunately the map is not showing the current location and even the location service does not get turn on the phone even the app is granted permission to access GPS. Since i'm not a expect in iOS development I need someone to look the code and explain what is missing in this code. I looked at similar question but they seem straight forward even for someone learning objective-c. The problem with this code i assume is the SWRevealViewController imported here, which I think is a library or something i don't know.

}
In addition to the previous answer, note that you have to specify the reason for accessing the user's location information adding the relative key (NSLocationAlwaysUsageDescription or NSLocationWhenInUseUsageDescription) to your project's Info.plist
for example:
<key>NSLocationWhenInUseUsageDescription</key>
<string>Location is required to find out jobs around you are</string>
On iOS 8, they changed how you ask for location permission. Instead of just being able to call startUpdatingLocation you need to now call either requestWhenInUseAuthorization or requestAlwaysAuthorization.

iBeacon and Notification

i'm developing an iOS application and i'm using beacons.
I've a problem. I'm at the beginning of the development, so I only have my appdelegate. In appdelegate.m I have initialized like so
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
self.window = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]];
// Override point for customization after application launch.
self.locationManager = [[CLLocationManager alloc] init];
self.locationManager.delegate = self;
NSUUID *uuid = [[NSUUID alloc] initWithUUIDString:#"8AEFB031-6C32-486F-825B-E26FA193487D"];
CLBeaconRegion *region = [[CLBeaconRegion alloc] initWithProximityUUID:uuid
identifier:#"Region"];
if ([CLLocationManager isMonitoringAvailableForClass:[CLBeaconRegion class]])
{
NSLog(#"I'm looking for a beacon");
[self.locationManager startRangingBeaconsInRegion:region];
} else {
NSLog(#"Device doesn't support beacons ranging");
}
return YES;
}
and then I wrote two delegate methods
- (void) locationManager:(CLLocationManager *)manager didExitRegion:(CLRegion *)region {
NSLog(#"EXIT");
}
- (void) locationManager:(CLLocationManager *)manager didEnterRegion:(CLRegion *)region {
NSLog(#"ENTER");
}
but they never get called!!! What's the problem here?
you RANGE but you never MONITOR the regions.
Ranging for beacons will only call: locationManager:didRangeBeacons:inRegion:
The methods enterRegion/exitRegion you want are for monitoring only. So call:
- (void)startMonitoringForRegion:(CLRegion *)region
I don't know why there are not calling but this is how we can handle beacons...
- (void)createBeaconRegion
{
self.locationManager = [[CLLocationManager alloc] init];
self.locationManager.delegate = self;
NSUUID *uuid = [[NSUUID alloc] initWithUUIDString:#"8AEFB031-6C32-486F-825B-E26FA193487D"];
CLBeaconRegion *region = [[CLBeaconRegion alloc] initWithProximityUUID:uuid
identifier:#"Region"];
if ([CLLocationManager isMonitoringAvailableForClass:[CLBeaconRegion class]])
{
NSLog(#"I'm looking for a beacon");
[self.locationManager startRangingBeaconsInRegion:region];
} else {
NSLog(#"Device doesn't support beacons ranging");
}
}
- (void)turnOnRanging
{
NSLog(#"Turning on ranging...");
if (![CLLocationManager isRangingAvailable]) {
NSLog(#"Couldn't turn on ranging: Ranging is not available.");
self.rangingSwitch.on = NO;
return;
}
if (self.locationManager.rangedRegions.count > 0) {
NSLog(#"Didn't turn on ranging: Ranging already on.");
return;
}
[self createBeaconRegion];
[self.locationManager startRangingBeaconsInRegion:self.beaconRegion];
NSLog(#"Ranging turned on for region: %#.", self.beaconRegion);
}
- (void)startRangingForBeacons
{
self.locationManager = [[CLLocationManager alloc] init];
self.locationManager.delegate = self;
self.detectedBeacons = [NSArray array];
[self turnOnRanging];
}
- (void)stopRangingForBeacons
{
if (self.locationManager.rangedRegions.count == 0) {
NSLog(#"Didn't turn off ranging: Ranging already off.");
return;
}
[self.locationManager stopRangingBeaconsInRegion:self.beaconRegion];
NSLog(#"Turned off ranging.");
}
You can refer the entire sample project using below link

That uses to display Beacons..
Hope it helps you....!

How to get paired bluetooth devices

I want to create one application that show me paired devices in my app.(for example any device that paired me before detect and show me.)
also in the next time I want to send one NSString like "hello" to paired device.
I searching in google and I got so confused!!!
Please tell me first how to get paired device with my mobile and second how to send NSString value to them.
Here is an exemple for what you need :
You have to adapt it to match what u want. But you can see how it work ...
#implementation ViewController

}
- (void)_updateEmitterForDesiredState

I have location Manager. User can create tasks and pick distinction location. When user come to location - I show local notification. It works for one task. When I have more that one task some strange appear: I receive many notifications. I receive all scheduled notifications.
Question: how can I manage location Manager and push local notifications for different regions? Example: I have three regions - one in Moscow, one in London and one in New York. So, when user come to Moscow I want see only one notification (#"Notification 1"). When in London - notification 2. When in New York - notification 3.

Each CLRegion you add to monitor has an identifier, you can use this to identify which region is entered.
