闲言简之，代码先观为敬。
WTEscape
描述
- 解决xcode控制台打印，中文显示为Unicode编码的问题。
- 打印对象的时候，可以将对象的属性值打印出来。
使用方法
只需将
*+WTEscape类引入您的项目中，无需进行其他任何操作和配置，在debug模式下控制台输出的Unicode即可显示为中文。打印对象的时候，对象的属性值也会一并打印。
原理简介之
1、基础之数据类型打印
- (NSString *)descriptionWithLocale:(id)locale indent:(NSUInteger)level;
以此法为引，文之重组之，终以字符串拼接之，遂控制台打印可解之。
2、对象属性之打印
- (NSString *)description;
唯基类入手焉得善果，NSObject以此法为引。
unsigned int ivarsCount = 0;
Ivar *ivars = class_copyIvarList([self class], &ivarsCount);
for (int i = 0; i < ivarsCount; i++) {
NSString *key = [NSString stringWithUTF8String:ivar_getName(ivars[i])];
id objct = [self valueForKey:key];
...
...
...
}
free(ivars);
运行时辅之，遍寻属性之值做字符串拼接状，而后输出可阅之果。
例之可视也
NSArray *array = @[@"你好", @"他好", @"大家好"];
NSDictionary *dataDic = @{@"姓名" : @"李四",
@"性别" : @"男",
@"爱好" : @{@"游泳" : @"不会", @"篮球" : @"也不会", @"骑车" : @"马马虎虎"},
@"朋友" : @[@"大亨", @"jobson", @"李磊"]
};
NSData *data = [NSJSONSerialization dataWithJSONObject:dataDic options:0 error:NULL];
NSSet *set = [[NSSet alloc] initWithObjects:@"这是一个set", data, dataDic, array, nil];
UIImage *image = [UIImage imageNamed:@"WTIMAGE.png"];
Car *car = [[Car alloc] init];
car.brand = @"Benze";
car.color = [UIColor redColor];
car.image = image;
car.rect = CGRectMake(0, 0, 100, 100);
NSDictionary *dictionary = @{@"姓名" : @"张三",
@"性别" : @"男",
@"data" : data,
@"set" : set,
@"array" : array,
@"image" : image,
@"car" : car,
};
NSLog(@"%@",dictionary);
如上之对象，未用WTEscape修饰之，打印如下也
