I am using iBeacons manufactured by JAALEE, Liam trying get list go iBeacons near to me but i am not able to get it

Dont know how to resolve this. i want to use this to get Proximity UUID from detected beacon.
GIT LINK OF SDK
If you ibeacon do not have any additional features as estimote ibeacons(accelerometers and temperature sensor), you must not use SDK.
Look at this tutorial for iOS 8 and change the UUID.

I am having issues with Storyboards AutoRotation and the iPhone. I've put together a VERY simple project with 3 view controllers which I uploaded to gitHub to demonstrate the issue
I've tested this on the following devices:
IPAD 3
IPHONE 5s
Simulator (iphone / ipad)
Everything seems to work perfectly on the iPad & Simulator (Iphone/Ipad) but when I run it on the 5s it does not rotate correctly.
On the iPhone it will rotate the alert view but not the view controller it appears
On the simulator this is the result (which looks correct)
Code for sample project can be found at:
https://github.com/jlss/RotationIssues
I am happy and willing to try ANY suggestions anybody has.
Things of Note: (I am using the call objc_msgSend([UIDevice currentDevice], #selector(setOrientation:), UIInterfaceOrientationLandscapeLeft); ) but as far as I can tell this should be ok.

And lastly i have a simple storyboard with:
Unfortunately you cannot do this if you are using push segues. You have to use modal.
I have a problem with my parse backend app.
On Parse I have a Class like this: name (string) , imageFile (File) and help (string).
Everything works great except the Images. When I tap on a cell, I am pushed to the DetailViewController the 2 Strings appear but the ImageView (PFImageView) is empty. The ImageView does not show my Images.
Maybe there is a problem with passing the image file?

Create a PFObject in DetailViewController

Pass a PFObject from master to detail

I have an app I am working on, and I am trying to have the logo on for a bit longer, and fade out/slide out/effect when it's done.
Here's my setup:
The Tab Bar controller is not letting me place an Image View inside it, so I created a view to have it on.
I am trying to have the logo stay on for a bit, fade out, then automatically switch the view (Segue) to the Tab Bar controller.
This is what I get out of it: http://youtu.be/l4jL0BfpR2k

// Do any additional setup after loading the view.
[UIView animateWithDuration:1 animations:^{
_imageview.alpha = 0;
}];
//BDNTabBarController *viewController = [[BDNTabBarController alloc] init];

}

// Dispose of any resources that can be recreated.
}
#end
Yes, "open" is defined as the segue id.
Do you guys have any ideas on how I could fix this?
To fix, add this
- (void) viewDidAppear:(BOOL)animated
{
[super viewDidAppear:YES];
[self performSegueWithIdentifier:#"open" sender:self];
}
Remove this from your code
(void)#selector(seguePerform:);
// and all other unnecessary segue stuff you had
pass data from FirstViewController to DetailViewController. i can not set the text of label in DetailViewController; FirstViewController is a tableview and it is good.
i use method updateRowNumber to set the rowNumber . and in DetailViewController, i can use debugger to see the rowNumber is correct. but the label's text is not showed on the view.
anyone can help me out?
in my FirstViewController
- (void) tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
if (dvController == nil)
{
DetailViewController *aController = [[DetailViewController alloc] initWithNibName:#"DetailViewController" bundle:nil];
self.dvController = aController;
[aController release];
}
[[self navigationController] pushViewController:dvController animated:YES];
[dvController updateRowNumber:indexPath.row];
}

#import <UIKit/UIKit.h>

if (self) {
// Custom initialization
}
return self;
}
- (void) updateRowNumber: (int) theindex
{
rowNumber = theindex + 1;
message.text = [NSString stringWithFormat:#"row %i was clicked", rowNumber];
}
- (void)dealloc
{
[message release];
[super dealloc];
}
- (void)viewDidLoad
{
message.text = [NSString stringWithFormat:#"row %i was clicked ", rowNumber];
[super viewDidLoad];
// Do any additional setup after loading the view from its nib.
}
- (void)viewDidUnload
{
[super viewDidUnload];
// Do any additional setup after loading the view from its nib.
}

[super viewDidAppear: animated];

You'll need to learn how the view is loaded, the process is well described in the documentation
What happens is that the view and all the outlets are nil until the view is loaded, you can make sure it is loaded by calling self.view; before configuring the outlet at updateRowNumber:
Please also note, you are better to call [super viewDidLoad] in the beginning of the overridden viewDidLoad, it makes sense as you need to let UIViewContorller to do it's staff before you do some customized logic, the dealloc is different as you need to do your logic before the standard NSObject -dealloc fires. Hope it's understandable.
I am trying to send a nsmutablearray from one navigational embedded view controller to another viewcontroller after this method
- (void)mapView:(MKMapView *)mapView annotationView:(MKAnnotationView *)view calloutAccessoryControlTapped:(UIControl *)control{NSLog(#"tapped %# %d",view.annotation.title,[res count]);
gpDetailViewController *gpDetailView = [[gpDetailViewController alloc] init];
gpDetailView.title = #"Details";
gpDetailView.detailArray = res;
[self.navigationController pushViewController:gpDetailView animated:YES];
}
is executed.

I am getting a null value when i am trying to print the array elements size.
What could be the reason?
Instead of
NSLog(#"%#",[self.detailArray count]);
try this
NSLog(#"%d",[self.detailArray count]);
count is an integer, not a class
