输出中文

原理

• 就是给NSDictionary添加一个分类

步骤

• 创建一个Foundation+Log.m文件
• 在.m问价实现代码

#import 

@implementation NSDictionary (Log)


-(NSString *)descriptionWithLocale:(id)locale
{
    NSMutableString *string = [NSMutableString string];

    [string appendString:@"{\n"];
    
    [self enumerateKeysAndObjectsUsingBlock:^(id  _Nonnull key, id  _Nonnull obj, BOOL * _Nonnull stop) {
       
        [string appendFormat:@"%@:",key];
        [string appendFormat:@"%@,\n",obj];
    }];

    [string appendString:@"}"];

    NSRange range = [string rangeOfString:@"," options:NSBackwardsSearch];
    if (range.location != NSNotFound) {
        [string deleteCharactersInRange:range];
    }
    return string;
}

@end


@implementation NSArray (Log)


-(NSString *)descriptionWithLocale:(id)locale
{
    NSMutableString *string = [NSMutableString string];

    [string appendString:@"["];

   [self enumerateObjectsUsingBlock:^(id  _Nonnull obj, NSUInteger idx, BOOL * _Nonnull stop) {
       [string appendFormat:@"%@,",obj];
       
   }];

    [string appendString:@"]"];
    
    NSRange range = [string rangeOfString:@"," options:NSBackwardsSearch];
    if (range.location != NSNotFound) {
        [string deleteCharactersInRange:range];
    }
    
    return string;
}
