##UIBarButtonItem+Badge
This is categorization of this github Class. Its expanded for UIButton use too.
Create a BarButtonItem with a badge on top. Easily customizable. Your BarButtonItem can be any custom view you wish for. The badge on top can display any number or string of any size or length.
Create a UIButton with a badge on top. Easily customizable. Your UIButton can be any button you wish to use. The badge on top can display any number or string of any size or length.
It's quite easy, just download and add "UIBarButtonItem+Badge.h" and "UIBarButtonItem+Badge.m" into your xcodeproject.
Don't forget to import the header file wherever you need it :
#import "UIBarButtonItem+Badge.h"Then, to add a badge call setBadgeValue on the UIBarButton item and the trick is done! Make sure you're using UIBarButtonItem with custom view
// Build your regular UIBarButtonItem with Custom View
UIImage *image = [UIImage imageNamed:@"someImage"];
UIButton *button = [UIButton buttonWithType:UIButtonTypeCustom];
button.frame = CGRectMake(0,0,image.size.width, image.size.height);
[button addTarget:self action:@selector(buttonPress:) forControlEvents:UIControlEventTouchDown];
[button setBackgroundImage:image forState:UIControlStateNormal];
// Make BarButton Item
UIBarButtonItem *navLeftButton = [[UIBarButtonItem alloc] initWithCustomView:button];
self.navigationItem.leftBarButtonItem = navLeftButton;
self.navigationItem.leftBarButtonItem.badgeValue = @"1";A new merge now enables adding badge without a custom view
UIImage *image = [UIImage imageNamed:@"someImage"];
UIBarButtonItem *navLeftButton = [[UIBarButtonItem alloc] initWithImage:image
style:UIBarButtonItemStylePlain
target:self
action:@selector(buttonPress:)];
self.navigationItem.leftBarButtonItem = navLeftButton;
self.navigationItem.leftBarButtonItem.badgeValue = @"1";Take a look at UIBarButtonItem+Badge.h to see how you can customize the badge. Remember that each time you change one of these value, the badge will directly be refresh to handle your styling preferences.
// Each time you change one of properties, the badge will refresh with your changes
// Badge value to be display
@property (nonatomic) NSString *badgeValue;
// Badge background color
@property (nonatomic) UIColor *badgeBGColor;
// Badge text color
@property (nonatomic) UIColor *badgeTextColor;
// Badge font
@property (nonatomic) UIFont *badgeFont;
// Padding value for the badge
@property (nonatomic) CGFloat badgePadding;
// Minimum size badge to small
@property (nonatomic) CGFloat badgeMinSize;
// Values for offseting the badge over the BarButtonItem you picked
@property (nonatomic) CGFloat badgeOriginX;
@property (nonatomic) CGFloat badgeOriginY;
// In case of numbers, remove the badge when reaching zero
@property BOOL shouldHideBadgeAtZero;
// Badge has a bounce animation when value changes
@property BOOL shouldAnimateBadge;You can also choose to turn off the little bounce animation triggered when changing the badge value or decide if 0 should be display or not.
The class is compatible with iOS >= 6.0.
Any suggestions are welcome ! as I am looking to learn good practices, to understand better behaviors and Objective-C in general ! Thank you.
