iOS中解决Xcode9的Log日志无法输出中文的问题小结

问题描述

Xcode的Log日志输出中文的问题,一般都是重写NSArray,NSDictionary的- (NSString *)descriptionWithLocale:(id)locale;方法进行处理,最近升级到Xcode9会后发现原来的处理逻辑也无法满足输出中文的需求,后台返回的状态描述涉及到中文的都变成了Unicode编码,其实这是重写的方法失效的问题,因为Xcode默认输出NSArray,NSDictionary的中文都是Unicode编码

正确的解决方案如下, 创建NSArray+ZYLog分类

NSArray+ZYLog.h文件

@implementation NSArray (ZYLog)
#ifdef DEBUG
- (NSString *)description {
 return [self ZY_descriptionWithLevel:1];
}
-(NSString *)descriptionWithLocale:(id)locale{
 return [self ZY_descriptionWithLevel:1];
}
- (NSString *)descriptionWithLocale:(nullable id)locale indent:(NSUInteger)level {
 return [self ZY_descriptionWithLevel:(int)level];
}

- (NSString *)ZY_descriptionWithLevel:(int)level {
 NSString *subSpace = [self ZY_getSpaceWithLevel:level];
 NSString *space = [self ZY_getSpaceWithLevel:level - 1];
 NSMutableString *retString = [[NSMutableString alloc] init];
 // 1、添加 [
 [retString appendString:[NSString stringWithFormat:@"["]];
 // 2、添加 value
 [self enumerateObjectsUsingBlock:^(id _Nonnull obj, NSUInteger idx, BOOL * _Nonnull stop) {
  if ([obj isKindOfClass:[NSString class]]) {
   NSString *value = (NSString *)obj;
   value = [value stringByReplacingPercentEscapesUsingEncoding:NSUTF8StringEncoding];
   NSString *subString = [NSString stringWithFormat:@"n%@"%@",", subSpace, value];
   [retString appendString:subString];
  } else if ([obj isKindOfClass:[NSArray class]]) {
   NSArray *arr = (NSArray *)obj;
   NSString *str = [arr ZY_descriptionWithLevel:level + 1];
   str = [NSString stringWithFormat:@"n%@%@,", subSpace, str];
   [retString appendString:str];
  } else if ([obj isKindOfClass:[NSDictionary class]]) {
   NSDictionary *dic = (NSDictionary *)obj;
   NSString *str = [dic descriptionWithLocale:nil indent:level + 1];
   str = [NSString stringWithFormat:@"n%@%@,", subSpace, str];
   [retString appendString:str];
  } else {
   NSString *subString = [NSString stringWithFormat:@"n%@%@,", subSpace, obj];
   [retString appendString:subString];
  }
 }];
 if ([retString hasSuffix:@","]) {
  [retString deleteCharactersInRange:NSMakeRange(retString.length-1, 1)];
 }
 // 3、添加 ]
 [retString appendString:[NSString stringWithFormat:@"n%@]", space]];
 return retString;
}

- (NSString *)ZY_getSpaceWithLevel:(int)level {
 NSMutableString *mustr = [[NSMutableString alloc] init];
 for (int i=0; i

效果

而且直接就是json串,复制log日志,直接在json格式化工具中使用
