由于开发中图片文字居中显示很多,而且有时候还需要后台返回数据动态改变,如果我们按照之前的imge+label模式写,肯定会非常麻烦,而且不可控。所以本人写了一个简单的button不论适配5还是最新的x,都非常好用,调用一句话就行。以下是代码:
ZJButton.h

//#define WhiteSmoke [UIColor colorWithHex:@"#e7e7e7"]//DCDCDC
@interface ZJButton : UIButton

-(void)autoLayoutfNeedsWithBtn:(UIButton *)btn layerColor:(UIColor *)layerColor;

-(void)setBtn:(UIButton *)btn WithCount:(NSString *)count andName:(NSString *)name nameColor:(UIColor *)nameColor andCountFont:(CGFloat)countfont andNameFont:(CGFloat)nameFont;

-(void)setAttributeBtn:(UIButton *)btn WithImagename:(NSString *)imagename andtitle:(NSString *)title andTitleColor:(UIColor *)titlecolor andtitleFont:(CGFloat)fonts andimageBounds:(CGRect)bounds;
//添加btn超文本(图片右侧,文字左侧)

你可以创建这两个.h和.m文件,进去体验一哈,
