NSDictionary转化为实体类对象

方法一: 

使用objective-c NSObject自带的方法

setValuesForKeysWithDictionary:dict

作用是: 如果NSDictionary中的key和实体类对象的属性名相同,  那么把该key的value 设置到实体类对应的属性

- (instancetype)initWithDict:(NSDictionary *)dict{    if (self = [super init]) {        [self setValuesForKeysWithDictionary:dict];    }    return self;}

 

方法二: 网上的细化的方法

#import <objc/runtime.h>-(NSString *) className {  return NSStringFromClass([self class]);}- (void)objectFromDictionary:(NSDictionary*) dict {  unsigned int propCount, i;  objc_property_t* properties = class_copyPropertyList([self class], &propCount);  for (i = 0; i < propCount; i++) {    objc_property_t prop = properties;    const char *propName = property_getName(prop);    if(propName) {      NSString *name = [NSString stringWithCString:propName encoding:NSUTF8StringEncoding];      id obj = [dict objectForKey:name];      if (!obj)        continue;      if ([[obj className] isEqualToString:@"__NSCFString"] || [[obj className] isEqualToString:@"__NSCFNumber"]) {        [self setValue:obj forKeyPath:name];      } else if ([obj isKindOfClass:[NSDictionary class]]) {        id subObj = [self valueForKey:name];        if (subObj)          [subObj objectFromDictionary:obj];      }    }  }  free(properties);}- (id)initWithDictionary:(NSDictionary*) dict {  self = [self init];  if(self && dict)    [self objectFromDictionary:dict];  return self;}
