iOS Instantiate Custom View from Nib File across multiple UIViewController - ios

Question

I need an example of how to instantiate a custom view from a nib file. i wrapped my head around several stackoverflow posts but i didn't get it. Maybe i only need a hint how to do it.
what I want to do is - creating a custom view with interface builder. it should be a template so that i can instantiate it multiple times to add it to multiple view controllers.
So far I have created my custom view xib file called MyIssueView.xib. Which consists in fact just of the main view and some labels.
And I created a Subclass of UIView which is called IssueView with the Outlets for my labels in the MyIssueView.xib.
How do I now hook up the outlets with the IB? And how can I instantiate the IssueView from any ViewController?
Would be glad for an example!
Cheers.
UPDATE:
I now have
IssueView.xib
IssueView.h (UIView Subclass)
IssueView.m
My IssueView.h:
#import <UIKit/UIKit.h>
#interface IssueView : UIView
#property (weak, nonatomic) IBOutlet UILabel *label1;
#property (weak, nonatomic) IBOutlet UILabel *label2;
#property (weak, nonatomic) IBOutlet UILabel *label3;
#property (weak, nonatomic) IBOutlet UILabel *label4;
#end
My IssueView.m:
#import "IssueView.h"
#implementation IssueView
#end
My ViewController.m:
#import "AllIssuesViewController1.h"
#import "IssueView.h"
#import "UIView+NibLoading.h"
#interface AllIssuesViewController1 ()
#end
#implementation AllIssuesViewController1
- (void) loadView
{
}
- (void)viewDidLoad
{
[super viewDidLoad];
_issueView = [IssueView loadInstanceFromNib];
}
It gives me an error:
*** Terminating app due to uncaught exception 'NSUnknownKeyException', reason: '[<NSObject 0x8292580> setValue:forUndefinedKey:]: this class is not key value coding-compliant for the key label1.'

I have a category that extends UIView called UIView+NibLoading.
In it is this code...
#import "UIView+NibLoading.h"
#implementation UIView (NibLoading)
+ (id)loadInstanceFromNib
{
UIView *result;
NSArray* elements = [[NSBundle mainBundle] loadNibNamed:NSStringFromClass([self class]) owner:nil options:nil];
for (id anObject in elements) {
if ([anObject isKindOfClass:[self class]]) {
result = anObject;
break;
}
}
return result;
}
#end
Then when I want to instantiate a UIView subclass from a nib I just import the category and I can run...
self.issueView = [IssueView loadInstanceFromNib];\
You need to connect the labels like this...
If you connecting the labels to "File's Owner" then you'll need to remove those connections.
