SMTNavigationBar

SMTNavigationBar simply centralizes your custom navigation bar. Create navigation buttons once and viola you can access it on any of your UIViewControllers.

Quick Start

Cocoapods - Add in Podfile

pod 'SMTNavigationBar'

Import

#import "UIViewController+SMTNavigationBar.h"

Create button

 UIButton * leftBtn = [[UIButton alloc]initWithFrame:CGRectMake(0, 0, 44, 44)];
    [leftBtn setTitle:@"left" forState:UIControlStateNormal];
    [leftBtn setTitleColor:[UIColor redColor] forState:UIControlStateNormal];

[self createButtonWithKey:@"leftBtn" button:leftBtn];

Set button in the Navigation Bar

 [self setLeftBarButtonItemWithKey:@"leftBtn" isDefault:YES isPop:YES];

After this you can get the configured navigation bar by

Important : Always load defaults on viewWillAppear

 -(void)viewWillAppear:(BOOL)animated{
    [self loadDefaults];
    }

Load defaults individually

/* List of items
    LEFT_ITEM
    RIGHT_ITEM
    TITLE_ITEM
    TITLEVIEW_ITEM
*/
[self loadDefaultWithItem:RIGHT_ITEM];

Button Target Selectors

Using Blocks

[self setLeftBarButtonItemWithKey:@"leftBtn" isDefault:YES withSelectorBlock:^(UIViewController *vc) {
        //When controller is popped. VC becomes a uinavigationcontroller class.
        if([vc isKindOfClass:[UINavigationController class]]){
            UINavigationController * vcs = (UINavigationController *) vc;
            vc = [vcs viewControllers].lastObject;
        }
     NSLog(@"This is the block method generated on first VC but is now being presented in %@",vc.navigationItem.title);
     }];

Note: UIViewController * vc becomes a UINavigationController class if its presented after a pop. In such case use this inside the block

 if([vc isKindOfClass:[UINavigationController class]]){
            UINavigationController * vcs = (UINavigationController *) vc;
            vc = [vcs viewControllers].lastObject;
        }

Reusing blocks

 [self runLeftSuperBlock];
 [self runRightSuperBlock];

Target Selectors

Catch the button control event in their corresponding selectors.

    -(void)SMTNavigationBarDidTapLeftItem
    -(void)SMTNavigationBarDidTapRightItem
    -(void)SMTNavigationBarDidPop

Create titleview

 UIImageView * imgView =[[UIImageView alloc] initWithImage:[UIImage imageNamed:@"logo.png"]];
 imgView.contentMode = UIViewContentModeScaleAspectFill;
 imgView.clipsToBounds = NO;
 [self createTitleViewWithKey:@"titleView" titleview:imgView];

Set titleview

 [self setTitleViewWithKey:@"titleView" isDefault:YES];

Set title

[self setTitle:@"ABC" isDefault:YES];

See demo project for more detailed implementation
