在项目中肯定会遇到字体适配的问题,从上面可以看出:一般情况是在4,5,6上用一套字体大小,在6P上字体大小扩大1.5倍数。(淘宝字体是这样子的)
方法一:用宏定义适配字体大小(根据手机尺寸判断)
1.5代表6P尺寸的时候字体为1.5倍,5S和6尺寸时大小一样,也可根据需求自定义比例。
代码如下:
#define IsIphone6P SCREEN_WIDTH==414
#define SizeScale (IsIphone6P ? 1.5 : 1)
#define kFontSize(value) value*SizeScale
#define kFont(value) [UIFont systemFontOfSize:value*SizeScale]
方法二:用宏定义适配字体大小(根据手机尺寸判断)
//不同屏幕尺寸字体适配
#define kScreenWidthRatio (UIScreen.mainScreen.bounds.size.width / 375.0)
#define kScreenHeightRatio (UIScreen.mainScreen.bounds.size.height / 667.0)
#define AdaptedWidth(x) ceilf((x) * kScreenWidthRatio)
#define AdaptedHeight(x) ceilf((x) * kScreenHeightRatio)
#define AdaptedFontSize(R) [UIFont systemFontOfSize:AdaptedWidth(R)]
项目常用宏

// 导航栏高度
#define kNavigationBarHeight (iPhoneX ? 88.f : 64.f)
// home indicator
#define KIndicatorHeight (iPhoneX ? 34.f : 0.f)
