Installation 安装

1.手动安装:

下载/Download PPBadgeView Demo

Objective-C : 拖入PPBadgeView/objc文件夹中的.h与.m文件, #import "PPBadgeView.h" 开始使用
Swift : 拖入PPBadgeView/swift文件夹中的.swift文件开始使用
Objective-C: dragged into the .h file with the .m file in the PPBadgeView / objc folder, #import "PPBadgeView.h" then,start using
Swift: Drag the .swift file into the PPBadgeView / swift folder to get start

2.CocoaPods安装:

Objective-C : pod 'PPBadgeView' then #import <PPBadgeView.h>
Swift : pod 'PPBadgeViewSwift' then import PPBadgeViewSwift

如果发现pod search PPBadgeView/PPBadgeViewSwift 不是最新版本，在终端执行pod setup命令更新本地spec镜像缓存(时间可能有点长),重新搜索就OK了

If you find pod search PPBadgeView / PPBadgeViewSwift is not the latest version, in the terminal of the pod setup command to update the local spec image cache and re-search. (it may take you a long time)

Usage 使用方法

1. Objective-C :

view = UIView, UITabBarItem, UIBarButtonItem及其子类(subclass)

// 添加带文本内容的Badge, 默认右上角, 红色, 18pts
// Add Badge with text content, the default upper right corner, red backgroundColor, 18pts
[view pp_addBadgeWithText:@"99+"];

// 添加带数字的Badge, 默认右上角,红色,18pts
// Add the Badge with numbers, the default upper right corner, red backgroundColor, 18pts
[view pp_addBadgeWithNumber:1];

// 添加带颜色的小圆点, 默认右上角, 红色, 8pts
// Add small dots with color, the default upper right corner, red backgroundColor, 8pts
[view pp_addDotWithColor:nil];

/**
 设置Badge的高度,因为Badge宽度是动态可变的,通过改变Badge高度,其宽度也按比例变化,方便布局
(注意: 此方法需要将Badge添加到控件上后再调用!!!)
Set the height of Badge, because the Badge width is dynamically and  variable.By changing the Badge height in proportion to facilitate the layout.
(Note: this method needs to add Badge to the controls and then use it !!!)

 @param points 高度大小
 */
[view pp_setBadgeHeight:25];

/**
 设置Badge的偏移量, Badge中心点默认为其父视图的右上角
 Set Badge offset, Badge center point defaults to the top right corner of its parent view
 
 @param x X轴偏移量 (x<0: 左移, x>0: 右移) axis offset (x <0: left, x> 0: right)
 @param y Y轴偏移量 (y<0: 上移, y>0: 下移) axis offset ( Y <0: up, y> 0: down)
 */
[view pp_moveBadgeWithX:-7 Y:5];

/**
 设置Badge的属性
 */
[view pp_setBadgeLabelAttributes:^(PPBadgeLabel *badgeLabel) {
        badgeLabel.backgroundColor = [UIColor redColor];
        badgeLabel.font =  [UIFont systemFontOfSize:13];
        badgeLabel.textColor = [UIColor blueColor];
    }];

// 数字增加/减少, 注意:以下方法只适用于Badge内容为纯数字的情况
// Digital increase /decrease, note: the following method applies only to cases where the Badge content is purely numeric
[view pp_decrease];
[view pp_increase];

2. Swift :

view = UIView, UITabBarItem, UIBarButtonItem及其子类

// 添加带文本内容的Badge, 默认右上角, 红色, 18pts
// Add Badge with text content, the default upper right corner, red backgroundColor, 18pts
view?.pp.addBadge(text: "99+");

// 添加带数字的Badge, 默认右上角,红色,18pts
// Add the Badge with numbers, the default upper right corner, red backgroundColor, 18pts
view?.pp.addBadge(number: 1);

// 设置Badge的高度,因为Badge宽度是动态可变的,通过改变Badge高度,其宽度也按比例变化,方便布局
// (注意: 此方法需要将Badge添加到控件上后再调用!!!)
// Set the height of Badge, because the Badge width is dynamically and  variable.By changing the Badge height in proportion to facilitate the layout.
// (Note: this method needs to add Badge to the controls and then use it !!!)
view?.pp.setBadgeHeight(21.0);

/// 设置Badge的偏移量, Badge中心点默认为其父视图的右上角 Set Badge offset, Badge center point defaults to the top right corner of its parent view
///
/// - Parameters:
///   - x: X轴偏移量 (x<0: 左移, x>0: 右移) axis offset (x <0: left, x> 0: right)
///   - y: Y轴偏移量 (y<0: 上移, y>0: 下移) axis offset ( Y <0: up, y> 0: down)
view?.pp.moveBadge(x: -7, y: 5)

// 自定义badge的属性: 字体大小/颜色, 背景颜色...(默认系统字体13,白色,背景色为系统badge红色)
// Custom badge properties: font size / color, background color... (default system font 13, white, background color is system Badge Red)
view?.pp.setBadgeLabel(attributes: { (badgeLabel) in
      badgeLabel.font = UIFont.systemFont(ofSize: 13)
      badgeLabel.textColor = UIColor.blue
})

// 数字增加/减少, 注意:以下方法只适用于Badge内容为纯数字的情况
// Digital increase /decrease, note: the following method applies only to cases where the Badge content is purely numeric
view?.pp.decrease()
view?.pp.increase()
