- 本文章适用于使用xib或者storyboard开发过程中，控件根据自己的宏定义的比例处理文字（font）等比，话不多说，先看效果，再上代码。

创建分类UIButton+XibScaleAdapter分类，仅UIButton的font等比适配的分类
#import <UIKit/UIKit.h>
NS_ASSUME_NONNULL_BEGIN
@interface UIButton (XibScaleAdapter)
@property(nonatomic, assign) IBInspectable BOOL adapterFont;
@end
NS_ASSUME_NONNULL_END
#import "UIButton+XibScaleAdapter.h"
#define C_WIDTH(WIDTH) WIDTH * [UIScreen mainScreen].bounds.size.width/375.0
@implementation UIButton (XibScaleAdapter)
- (void)setAdapterFont:(BOOL)adapterFont{
if (adapterFont) {
UIFontDescriptor *ctFont = self.titleLabel.font.fontDescriptor;
NSNumber *fontString = [ctFont objectForKey:@"NSFontSizeAttribute"];
self.titleLabel.font = [UIFont fontWithName:self.titleLabel.font.familyName size:C_WIDTH([fontString floatValue])];
}else{
self.titleLabel.font = self.titleLabel.font;
}
}
- (BOOL)adapterFont{
return self.adapterFont;
}
@end
创建分类UILabel+XibScaleAdapter分类，仅UILabel的font等比适配的分类
#import <UIKit/UIKit.h>
NS_ASSUME_NONNULL_BEGIN
@interface UILabel (XibScaleAdapter)
@property(nonatomic, assign) IBInspectable BOOL adapterFont;
@end
NS_ASSUME_NONNULL_END
#import "UILabel+XibScaleAdapter.h"
#define C_WIDTH(WIDTH) WIDTH * [UIScreen mainScreen].bounds.size.width/375.0
@implementation UILabel (XibScaleAdapter)
- (void)setAdapterFont:(BOOL)adapterFont{
if (adapterFont) {
UIFontDescriptor *ctFont = self.font.fontDescriptor;
NSNumber *fontString = [ctFont objectForKey:@"NSFontSizeAttribute"];
self.font = [UIFont fontWithName:self.font.familyName size:C_WIDTH([fontString floatValue])];
NSLog(@"%@",self.font);
}else{
self.font = self.font;
}
}
- (BOOL)adapterFont{
return self.adapterFont;
}
@end
创建分类UITextField+XibScaleAdapter分类，仅UITextField的font等比适配的分类
#import <UIKit/UIKit.h>
NS_ASSUME_NONNULL_BEGIN
@interface UITextField (XibScaleAdapter)
@property(nonatomic, assign) IBInspectable BOOL adapterFont;
@end
NS_ASSUME_NONNULL_END
#import "UITextField+XibScaleAdapter.h"
#define C_WIDTH(WIDTH) WIDTH * [UIScreen mainScreen].bounds.size.width/375.0
@implementation UITextField (XibScaleAdapter)
- (void)setAdapterFont:(BOOL)adapterFont{
if (adapterFont) {
UIFontDescriptor *ctFont = self.font.fontDescriptor;
NSNumber *fontString = [ctFont objectForKey:@"NSFontSizeAttribute"];
self.font = [UIFont fontWithName:self.font.familyName size:C_WIDTH([fontString floatValue])];
NSLog(@"%@",self.font);
}else{
self.font = self.font;
}
}
- (BOOL)adapterFont{
return self.adapterFont;
}
@end
创建分类UITextView+XibScaleAdapterr分类，仅UITextView的font等比适配的分类
#import <UIKit/UIKit.h>
NS_ASSUME_NONNULL_BEGIN
@interface UITextView (XibScaleAdapter)
@property(nonatomic, assign) IBInspectable BOOL adapterFont;
@end
NS_ASSUME_NONNULL_END
#import "UITextView+XibScaleAdapter.h"
#define C_WIDTH(WIDTH) WIDTH * [UIScreen mainScreen].bounds.size.width/375.0
@implementation UITextView (XibScaleAdapter)
- (void)setAdapterFont:(BOOL)adapterFont{
if (adapterFont) {
UIFontDescriptor *ctFont = self.font.fontDescriptor;
NSNumber *fontString = [ctFont objectForKey:@"NSFontSizeAttribute"];
self.font = [UIFont fontWithName:self.font.familyName size:C_WIDTH([fontString floatValue])];
NSLog(@"%@",self.font);
}else{
self.font = self.font;
}
}
- (BOOL)adapterFont{
return self.adapterFont;
}
@end
以上是整体使用、实现、效果，因为在代码里面定义的等比适配基准机型是8（宽度375），基准屏宽度的定义取决于UI出的尺寸图是按什么机型出的，UI按什么机型出，基准屏幕的尺寸定义就对应什么机型的宽度就好。
