将Xcode中控制台的Unicode转为中文

废话不多说,直接看截图和上代码 (有问题可以留言)。

代码如下

在NSObject分类中的.h文件中的代码

//

@interface NSObject (ChangeUnicode)

+(NSString *)stringByReplaceUnicode:(NSString *)string;

@end

@interface NSArray (LengUnicode)

@end

@interface NSDictionary (LengUnicode)

@end

在NSObject分类中的.m文件中的代码

//
//  NSObject+ChangeUnicode.m

#import "NSObject+ChangeUnicode.h"

#import <objc/runtime.h>   // 导入运行时

@implementation NSObject (ChangeUnicode)

+(NSString *)stringByReplaceUnicode:(NSString *)string{
    
    NSMutableString *convertedString=[string mutableCopy];
    [convertedString replaceOccurrencesOfString:@"\\U" withString:@"\\u" options:0 range:NSMakeRange(0, convertedString.length)];
    CFStringRef transform=CFSTR("Any-Hex/Java");
    CFStringTransform((__bridge CFMutableStringRef)convertedString, NULL, transform, YES);
    return convertedString;
}
@end

@implementation NSArray (LengUnicode)

+ (void)load {
    method_exchangeImplementations(class_getInstanceMethod([self class], @selector(description)), class_getInstanceMethod([self class], @selector(replaceDescription)));
    method_exchangeImplementations(class_getInstanceMethod([self class], @selector(descriptionWithLocale:)), class_getInstanceMethod([self class], @selector(replaceDescriptionWithLocale:)));
    method_exchangeImplementations(class_getInstanceMethod([self class], @selector(descriptionWithLocale:indent:)), class_getInstanceMethod([self class], @selector(replaceDescriptionWithLocale:indent:)));
}

- (NSString *)replaceDescription {
    return [NSObject stringByReplaceUnicode:[self replaceDescription]];
}

- (NSString *)replaceDescriptionWithLocale:(nullable id)locale {
    return [NSObject stringByReplaceUnicode:[self replaceDescriptionWithLocale:locale]];
}

- (NSString *)replaceDescriptionWithLocale:(nullable id)locale indent:(NSUInteger)level {
    return [NSObject stringByReplaceUnicode:[self replaceDescriptionWithLocale:locale indent:level]];
}
@end

@implementation NSDictionary (LengUnicode)

+ (void)load {
    method_exchangeImplementations(class_getInstanceMethod([self class], @selector(description)), class_getInstanceMethod([self class], @selector(replaceDescription)));
    method_exchangeImplementations(class_getInstanceMethod([self class], @selector(descriptionWithLocale:)), class_getInstanceMethod([self class], @selector(replaceDescriptionWithLocale:)));
    method_exchangeImplementations(class_getInstanceMethod([self class], @selector(descriptionWithLocale:indent:)), class_getInstanceMethod([self class], @selector(replaceDescriptionWithLocale:indent:)));
}

- (NSString *)replaceDescription {
    return [NSObject stringByReplaceUnicode:[self replaceDescription]];
}

- (NSString *)replaceDescriptionWithLocale:(nullable id)locale {
    return [NSObject stringByReplaceUnicode:[self replaceDescriptionWithLocale:locale]];
}

- (NSString *)replaceDescriptionWithLocale:(nullable id)locale indent:(NSUInteger)level {
    return [NSObject stringByReplaceUnicode:[self replaceDescriptionWithLocale:locale indent:level]];
}
@end

最后直接再重新运行一下项目，看下控制台的打印即可！！！
