iOS如何封装倒计时按钮HLCountDownButton(hlcountdownbutton,ios,开发技术)

演示图

可选自定义属性

///样式，默认HLCountDownButtonTypeNormal@property(nonatomic,assign)IBInspectableNSIntegerhlTypeUI_APPEARANCE_SELECTOR;///是否可用，默认YES@property(nonatomic,assign)IBInspectableBOOLhlEnabledUI_APPEARANCE_SELECTOR;///正常标题，默认“获取验证码”@property(nonatomic,copy)IBInspectableNSString*normalTitleUI_APPEARANCE_SELECTOR;///重新获取标题，默认“获取验证码”@property(nonatomic,copy)IBInspectableNSString*againTitleUI_APPEARANCE_SELECTOR;///发送中标题格式，默认“%ds后获取”@property(nonatomic,copy)IBInspectableNSString*sendingTitleFormatUI_APPEARANCE_SELECTOR;///高亮颜色，默认0x4181FE@property(nonatomic,strong)IBInspectableUIColor*highlightedColorUI_APPEARANCE_SELECTOR;///非高亮颜色，默认0xd2d2d2@property(nonatomic,strong)IBInspectableUIColor*disabledColorUI_APPEARANCE_SELECTOR;///圆角半径，默认4@property(nonatomic,assign)IBInspectableCGFloatcornerRadiusUI_APPEARANCE_SELECTOR;///边框宽度，默认0.5@property(nonatomic,assign)IBInspectableCGFloatborderWidthUI_APPEARANCE_SELECTOR;///倒计时长，默认60s@property(nonatomic,assign)IBInspectableNSIntegercountDownSizeUI_APPEARANCE_SELECTOR;

3种样式选择

typedefNS_ENUM(NSInteger,HLCountDownButtonType){HLCountDownButtonTypeNormal,///<无背景，无边框HLCountDownButtonTypeOnlyLine,///<无背景，有边框HLCountDownButtonTypeOnlyBackground,///<有背景，无边框};

回调说明

__weaktypeof(self)weakSelf=self;self.countDownButton.startBlock=^(){//TODO点击了倒计时按钮，这里可进行发送验证码操作//[weakSelfsendCodeMsg];};

注意：点击了会有startBlock回调，就不要为HLCountDownButton添加点击Action了

全局样式设置

如果您项目中多个地方使用到该组件，您可以全局设置样式，例在AppDelegate添加

[HLCountDownButtonappearance].highlightedColor=[UIColorredColor];

注意：代码 > appearance > interface builder，所以appearance设置的会覆盖在xib或storyboard中设置的属性，当然代码会覆盖appearance设置
