為了便於日常開發效率,因此建立了一些小的工具類便於使用. 具體 code 如下: 宣告:

/*
 為控制元件新增邊框樣式_工具類
 */
#import <UIKit/UIKit.h>

typedef NS_ENUM(NSInteger,LQQSideType) {
    kLQQSideTypeTop    = 0,
    kLQQSideTypeLeft   = 1,
    kLQQSideTypeBottom = 2,
    kLQQSideTypeRight  = 3,
    kLQQSideTypeAll    = 4,
};

typedef NS_ENUM(NSInteger,LQQSideAngleType) {
    kLQQSideAngleTypeTopLeft         = 0,
    kLQQSideAngleTypeTopRight        = 1,
    kLQQSideAngleTypeBottomLeft      = 2,
    kLQQSideAngleTypeBottomRight     = 3,
    kLQQSideAngleTypeAll             = 4,
};



@interface UIView (FYH)

/**

 @param sideType        圓角型別
 @param cornerRadius    圓角半徑

- (void)cornerSideType:(LQQSideType)sideType withCornerRadius:(CGFloat)cornerRadius;

- (void)cornerSideAngleType:(LQQSideAngleType)sideType withCornerRadius:(CGFloat)cornerRadius;


/**

 @param sideType    哪個邊
 @param color       邊框顏色
 @param width       邊框寬度
 */
- (void)cornerSideType:(LQQSideType)sideType lineColor:(UIColor *)color lineWidth:(CGFloat)width;
