背景

  • 使用代码方式进行布局通常会写很多代码，使得整个布局结构看起来比较杂乱，编写起来也很繁琐。可以通过 Category 方式对系统常用控件的接口进行封装，使得创建或设置这些控件变得非常简单、直观，代码整齐，达到意想不到的效果！

对 Button 和 Label 的封装

  • 以下是相关代码示例
+ (UIButton *)buttonWithTitleFont:(UIFont *)font titleColor:(UIColor *)color;

+ (UIButton *)buttonWithTitleFont:(UIFont *)font titleColor:(UIColor *)color title:(NSString *)title;

+ (UIButton *)buttonWithTitleFont:(UIFont *)font titleColor:(UIColor *)color backgroundColor:(UIColor *)backColor;

+ (UIButton *)buttonWithTitleFont:(UIFont *)font titleColor:(UIColor *)color title:(NSString *)title backgroundColor:(UIColor *)backColor;

- (void)setTitleFont:(UIFont *)font titleColor:(UIColor *)color;

- (void)setTitleFont:(UIFont *)font titleColor:(UIColor *)color title:(NSString *)title;

- (void)setTitleFont:(UIFont *)font titleColor:(UIColor *)color backgroundColor:(UIColor *)backColor;

- (void)setTitleFont:(UIFont *)font titleColor:(UIColor *)color title:(NSString *)title backgroundColor:(UIColor *)backColor;

- (void)setTitleFont:(UIFont *)font titleColor:(UIColor *)color normalTitle:(NSString *)normalTitle selectedTitle:(NSString *)selectedTitle;


+ (UILabel *)labelWithTextFont:(UIFont *)font textColor:(UIColor *)color;

+ (UILabel *)labelWithTextFont:(UIFont *)font textColor:(UIColor *)color text:(NSString *)text;

+ (UILabel *)labelWithTextFont:(UIFont *)font textColor:(UIColor *)color backgroundColor:(UIColor *)backColor;

+ (UILabel *)labelWithTextFont:(UIFont *)font textColor:(UIColor *)color text:(NSString *)text backgroundColor:(UIColor *)backColor;

+ (UILabel *)labelWithTextFont:(UIFont *)font textColor:(UIColor *)color text:(NSString *)text alignment:(NSTextAlignment)alignment;

+ (UILabel *)labelWithTextFont:(UIFont *)font textColor:(UIColor *)color text:(NSString *)text backgroundColor:(UIColor *)backColor alignment:(NSTextAlignment)alignment;

这样创建 Button 和 Label 会变得非常简单，一行代码即可搞定！

  • 一行代码即可设置按钮的 Image 和 Title 对齐方式，不再需要处理 imageEdgeInsets 和 titleEdgeInsets
- (void)layoutWithStyle:(LYButtonLayoutStyle)style andSpacing:(CGFloat)spacing


- (void)layoutWithStyle:(LYButtonLayoutStyle)style andSpacing:(CGFloat)spacing
{
    CGSize imageSize = self.imageView.frame.size;
    CGSize titleSize = self.titleLabel.frame.size;
    
    switch (style) {
        case LYButtonLayoutStyleImagePositionTop: {
            self.imageEdgeInsets = UIEdgeInsetsMake(-(titleSize.height + spacing) / 2, titleSize.width / 2, (titleSize.height + spacing) / 2, -(titleSize.width / 2));
            self.titleEdgeInsets = UIEdgeInsetsMake((imageSize.height + spacing) / 2, -(imageSize.width / 2), -(imageSize.height + spacing) / 2, imageSize.width / 2);
        }
            break;
            
        case LYButtonLayoutStyleImagePositionBottom: {
            self.imageEdgeInsets = UIEdgeInsetsMake((titleSize.height + spacing) / 2, titleSize.width / 2, -(titleSize.height + spacing) / 2, -(titleSize.width / 2));
            self.titleEdgeInsets = UIEdgeInsetsMake(-(imageSize.height + spacing) / 2, -(imageSize.width / 2), (imageSize.height + spacing) / 2, imageSize.width / 2);
        }
            break;
            
        case LYButtonLayoutStyleImagePositionLeft: {
            self.imageEdgeInsets = UIEdgeInsetsMake(0.0, -(spacing / 2), 0.0, spacing / 2);
            self.titleEdgeInsets = UIEdgeInsetsMake(0.0, spacing / 2, 0.0, -(spacing / 2));
        }
            break;
            
        case LYButtonLayoutStyleImagePositionRight: {
            self.imageEdgeInsets = UIEdgeInsetsMake(0.0, titleSize.width + spacing / 2, 0.0, -(titleSize.width + spacing / 2));
            self.titleEdgeInsets = UIEdgeInsetsMake(0.0, -(imageSize.width + spacing / 2), 0.0, (imageSize.width + spacing / 2));
        }
            break;
        default:
            break;
    }
}

注意

  • Category 中的方法没有添加前缀
