ARNavBar

Custom Navigation View and Drop Down menu developed in [VeespoFramework] (http://veespo.com). With this simple project I want to show how to use this two class:

• VENavBar is a simple NavigationBar with one or two buttons configurable that using blocks to comunicate with UIViewController
• VEDropDownMenu is a menu directly ispired by [NIDropDown project] (https://github.com/BijeshNair/NIDropDown) that works with VENavBar or others UIView.

VENavBar

To use simply add VENavBar.h and .m to your Xcode proj.

In your viewcontroller, initialize VENavBar passing frame and configuration. Configuration is defined with typedef VENavBarConfiguration

typedef enum {
    VENavBarDefault,
    VENavBarOnlyCloseBtn
} VENavBarConfiguration;

Using configuration you can, for example, decided if the navigationbar implements the drop down menu VEDropDownMenu.

- (id)initWithFrame:(CGRect)frame configuration:(VENavBarConfiguration)config;

Then you assign the block to the callback functions implemented by the class. VENavBar implemented three callback:

@property (nonatomic, copy) void (^menuPressed)(BOOL isOpen, VENavBar *navBar);
@property (nonatomic, copy) void (^closePressed)();
@property (nonatomic, strong) void (^functionRequest)(NSInteger number);

• menuPressed is called when menu button, if present, is pressed. isOpen inform you if the user has opened or closed the menu
• closePressed is called when the user pressed close button, in the case you want to close your viewcontroller
• functionRequest is called when the user select a voice in the drop down menu and numeber simply indicates which function has been selected.

If you want to close the drop down menu programmatically and not through menu button, you can use

- (void)closeMenu;

VEDropDownMenu

The main differences between my version and origianl [NIDropDown project] (https://github.com/BijeshNair/NIDropDown) are two:

• VEDropDownMenu implments block callbacks
• NIDropDown frame is designed in relation to the button that opens the menu, while I designed the menu in relation to the main view, in this specific case the navigation bar.

To use simply add VENavBar.h and .m to your Xcode proj.

In the code, to create ad instance of VEDropDownMenu, you should use the following method:

- (id)showDropDown:(UIView *)view titleList:(NSArray *)titleList imageList:(NSArray *)imageList directionDown:(BOOL)direction;

• view is the view from where the menu appears (is possibile to change this to a UIViewController)
• titleList array with the titles of the menu
• imageList icons fot each titles.
• direction determines whether the menu appears from top to bottom or vice versa.

I soon will replace NSArray with plist or NSDictionary.

This's a simple example about implementation of the menu in VENavBar, linked with a button.

- (IBAction)buttonPressed:(id)sender
{
    if (sender == closeBtn) {
        if (self.closePressed)
            self.closePressed();
    } else if (sender == menuBtn) {
        if(dropDown == nil) {
            self.menuPressed(YES, self);
            NSArray *arr = [NSArray arrayWithObjects:@"Add tag's comment", @"Tag info", @"Help", @"Languages", nil];
            NSArray *arrImage = [NSArray arrayWithObjects:[UIImage imageNamed:@"icona_commenti.png"],
                                 [UIImage imageNamed:@"icona_info.png"],
                                 [UIImage imageNamed:@"icona_help.png"],
                                 [UIImage imageNamed:@"cambio-lingua.png"], nil];
            dropDown = [[VEDropDownMenu alloc] showDropDown:self
                                                  titleList:arr
                                                  imageList:arrImage
                                              directionDown:YES];
            __weak id bSelf = self;
            dropDown.function = ^(NSInteger index){
                [bSelf closeMenu];
                [bSelf sendRequest:index];
            };
            dropDown.releseMenu = ^{
                [bSelf closeMenu];
            };
        } else {
            [self closeMenu];
            self.menuPressed(NO, self);
        }
    }
}

- (void)closeMenu
{
    [dropDown hideDropDown:self];
    dropDown = nil;
}
