最近刚接到一个任务: 重构公司的一个很老的项目......

在对项目进行代码走读是,发现很多基础UI控件都没有封装,所以自己封装了一个基础的UILabel、UIButton控件类

　　.h文件内容

#import <Foundation/Foundation.h>

NS_ASSUME_NONNULL_BEGIN

@interface Bt_BaseUI : NSObject

+ (UILabel *)createLabelWithFrame:(CGRect)frame text:(NSString *)text fontSize:(CGFloat)fontSize textAlignment:(NSTextAlignment)textAlignment;

+ (UIButton *)createButtonWithFrame:(CGRect)frame target:(id)target title:(NSString *)title action:(SEL)action bgImage:(NSString *)bgImage normalImage:(NSString *)normalImage selectImage:(NSString *)selectImage;

@end

NS_ASSUME_NONNULL_END

　　.m文件内容
