Label keeps disappearing from my navigation menu - ios

Question

For some reason the label in my navigation bar keeps disappearing and only displaying my map icon and home button. Is it because I'm adding it as a barbuttonitem? Is there a way around this?
UIView *view1=[[UIView alloc]initWithFrame:CGRectMake(160, 5, 250, 70)];
UILabel *l1=[[UILabel alloc]initWithFrame:CGRectMake(0,5, 310, 70)];
l1.text=#"FIND THINGS TO DO";
l1.font=[UIFont fontWithName:#"Helvetica Neue LT Std" size:25.0];
l1.backgroundColor=[UIColor clearColor];
l1.textColor=[UIColor whiteColor];
l1.textAlignment=UITextAlignmentCenter;
[view1 addSubview:l1];
UIBarButtonItem *left2=[[UIBarButtonItem alloc]initWithCustomView:view1];
self.navigationItem.rightBarButtonItem=left2;
[self.navigationItem setHidesBackButton:YES];
self.navigationItem.hidesBackButton=YES;
self.navigationController.navigationBarHidden = NO;
UIImage* image3 = [UIImage imageNamed:#"home_btn.png"];
homeBtn = [[UIButton alloc] initWithFrame:CGRectMake(0, 18, 38, 38)];
[homeBtn setBackgroundImage:image3 forState:UIControlStateNormal];
[homeBtn addTarget:self action:#selector(Home)
forControlEvents:UIControlEventTouchUpInside];
[homeBtn setShowsTouchWhenHighlighted:YES];
UIBarButtonItem *home = [[UIBarButtonItem alloc] initWithCustomView:homeBtn];
NSArray *arr=[[NSArray alloc]initWithObjects:home, nil];
self.navigationItem.rightBarButtonItems = arr;
UIImage* mapButton1 = [UIImage imageNamed:#"Top-Map-Icon.png"];
mapButton = [[UIButton alloc] initWithFrame:CGRectMake(0, 18, 26, 30)];
[mapButton setBackgroundImage:mapButton1 forState:UIControlStateNormal];
[mapButton addTarget:self action:#selector(Map)
forControlEvents:UIControlEventTouchUpInside];
[mapButton setShowsTouchWhenHighlighted:YES];
UIBarButtonItem *map = [[UIBarButtonItem alloc] initWithCustomView:mapButton];
NSArray *arr2 = [[NSArray alloc] initWithObjects:map, nil];
self.navigationItem.leftBarButtonItems = arr2;
