Converting from xib to storyboard - ios

Question

I'm having trouble converting my codes from xib format to storyboard for my iBeacon application. There is nothing showing on the table cells. All help is appreciated!
#import "RangingViewController.h"
#import "Default.h"
#implementation RangingViewController
{
NSMutableDictionary *_beacons;
CLLocationManager *_locationManager;
NSMutableArray *_rangedRegions;
}
- (id)initWithStyle:(UITableViewStyle)style
{
self = [super initWithStyle:style];
if(self)
{
_beacons = [[NSMutableDictionary alloc] init];
// This location manager will be used to demonstrate how to range beacons.
_locationManager = [[CLLocationManager alloc] init];
_locationManager.delegate = self;
}
return self;
}
- (void)locationManager:(CLLocationManager *)manager didRangeBeacons:(NSArray *)beacons inRegion:(CLBeaconRegion *)region
{
// CoreLocation will call this delegate method at 1 Hz with updated range information.
// Beacons will be categorized and displayed by proximity.
[_beacons removeAllObjects];
NSArray *unknownBeacons = [beacons filteredArrayUsingPredicate:[NSPredicate predicateWithFormat:#"proximity = %d", CLProximityUnknown]];
if([unknownBeacons count])
[_beacons setObject:unknownBeacons forKey:[NSNumber numberWithInt:CLProximityUnknown]];
NSArray *immediateBeacons = [beacons filteredArrayUsingPredicate:[NSPredicate predicateWithFormat:#"proximity = %d", CLProximityImmediate]];
if([immediateBeacons count])
[_beacons setObject:immediateBeacons forKey:[NSNumber numberWithInt:CLProximityImmediate]];
NSArray *nearBeacons = [beacons filteredArrayUsingPredicate:[NSPredicate predicateWithFormat:#"proximity = %d", CLProximityNear]];
if([nearBeacons count])
[_beacons setObject:nearBeacons forKey:[NSNumber numberWithInt:CLProximityNear]];
NSArray *farBeacons = [beacons filteredArrayUsingPredicate:[NSPredicate predicateWithFormat:#"proximity = %d", CLProximityFar]];
if([farBeacons count])
[_beacons setObject:farBeacons forKey:[NSNumber numberWithInt:CLProximityFar]];
[self.rangeTable reloadData];
}
- (void)viewDidAppear:(BOOL)animated
{
// Start ranging when the view appears.
[_rangedRegions enumerateObjectsUsingBlock:^(id obj, NSUInteger idx, BOOL *stop) {
CLBeaconRegion *region = obj;
[_locationManager startRangingBeaconsInRegion:region];
}];
}
- (void)viewDidDisappear:(BOOL)animated
{
// Stop ranging when the view goes away.
[_rangedRegions enumerateObjectsUsingBlock:^(id obj, NSUInteger idx, BOOL *stop) {
CLBeaconRegion *region = obj;
[_locationManager stopRangingBeaconsInRegion:region];
}];
}
- (void)viewDidLoad
{
[super viewDidLoad];
self.title = #"Ranging";
// Populate the regions we will range once.
_rangedRegions = [NSMutableArray array];
[[Default sharedDefaults].supportedProximityUUIDs enumerateObjectsUsingBlock:^(id uuidObj, NSUInteger uuidIdx, BOOL *uuidStop) {
NSUUID *uuid = (NSUUID *)uuidObj;
CLBeaconRegion *region = [[CLBeaconRegion alloc] initWithProximityUUID:uuid identifier:[uuid UUIDString]];
[_rangedRegions addObject:region];
}];
}
- (NSInteger)numberOfSectionsInTableView:(UITableView *)rangeTable
{
return _beacons.count;
}
- (NSInteger)tableView:(UITableView *)rangeTable numberOfRowsInSection:(NSInteger)section
{
NSArray *sectionValues = [_beacons allValues];
return [[sectionValues objectAtIndex:section] count];
}
- (NSString *)tableView:(UITableView *)rangeTable titleForHeaderInSection:(NSInteger)section
{
NSString *title = nil;
NSArray *sectionKeys = [_beacons allKeys];
// The table view will display beacons by proximity.
NSNumber *sectionKey = [sectionKeys objectAtIndex:section];
switch([sectionKey integerValue])
{
case CLProximityImmediate:
title = #"Immediate";
break;
case CLProximityNear:
title = #"Near";
break;
case CLProximityFar:
title = #"Far";
break;
default:
title = #"Unknown";
break;
}
return title;
}
- (UITableViewCell *)tableView:(UITableView *)rangeTable cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
static NSString *identifier = #"Cell";
_rangeCell = [rangeTable dequeueReusableCellWithIdentifier:identifier];
if (_rangeCell == nil)
{
_rangeCell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleSubtitle reuseIdentifier:identifier];
_rangeCell.selectionStyle = UITableViewCellSelectionStyleNone;
}
// Display the UUID, major, minor and accuracy for each beacon.
NSNumber *sectionKey = [[_beacons allKeys] objectAtIndex:indexPath.section];
CLBeacon *beacon = [[_beacons objectForKey:sectionKey] objectAtIndex:indexPath.row];
_rangeCell.textLabel.text = [beacon.proximityUUID UUIDString];
_rangeCell.detailTextLabel.text = [NSString stringWithFormat:#"Major: %#, Minor: %#, Acc: %.2fm", beacon.major, beacon.minor, beacon.accuracy];
return _rangeCell;
}
#end
I have declared the TableViewCell as _rangeCell and the TableView as rangeView.

In Storyboard
-First create a prototype cell without any subclass
-Remove all hooked links with the objects
-Set the cell Identifier
-Use my code below and let me know if the problem persist:
-(UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath{
static NSString *CellIdentifier = #"Cell";
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
// Configure the cell...
if (cell == nil) {
cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier];
}
// Set the indexes according to your UIControls Listing
UILabel *lblMainText = (UILabel *)[cell.contentView.subviews objectAtIndex:0];
UILabel *lblDetailText = (UILabel *)[cell.contentView.subviews objectAtIndex:3];
UILabel *lblDetailText2 = (UILabel *)[cell.contentView.subviews objectAtIndex:1];
UILabel *lblDetailText3 = (UILabel *)[cell.contentView.subviews objectAtIndex:2];
UIButton *btnFavourite = (UIButton *)[cell.contentView.subviews objectAtIndex:6];
UIButton *btnMore = (UIButton *)[cell.contentView.subviews objectAtIndex:4];
//cell.backgroundColor = [UIColor clearColor];
lblMainText.text = [NSString stringWithFormat:#"%#",#"someValue"];
lblDetailText.text= [NSString stringWithFormat:#"%#",#"someValue"];
lblDetailText2.text= [NSString stringWithFormat:#"%#",#"someValue"];
lblDetailText3.text= [NSString stringWithFormat:#"Marks",#"someValue"];
btnFavourite.tag = indexPath.row;
[btnFavourite addTarget:self
action:#selector(callMethod:) forControlEvents:UIControlEventTouchUpInside];
btnFavourite.tag = indexPath.row;
return cell;
}
