创建NSObject的类目，引入runtime

#import <objc/runtime.h>

.m文件

/** *  获取所有属性及对应的值 * */-(NSDictionary *)getAllPropertiesAndValues{    NSMutableDictionary *props = [NSMutableDictionary dictionary];    unsigned int outCount;    //属性的链表    objc_property_t *properties =class_copyPropertyList([self class], &outCount);    //遍历链表    for (int i = 0; i<outCount; i++)    {        objc_property_t property = properties[i];        //获取属性字符串        const char* propertyName =property_getName(property);        //转换成NSString        NSString *key = [NSString stringWithUTF8String:propertyName];        //获取属性对应的value        id value = [self valueForKey:key];        if (value)        {            [props setObject:value forKey:key];        }    }    //释放结构体数组内存    free(properties);    return props;}/** *  获取对象的所有属性 * *  @return 属性数组 */- (NSArray *)getAllProperties{    unsigned int count;    //获取属性的链表    objc_property_t *properties  =class_copyPropertyList([self class], &count);        NSMutableArray *propertiesArray = [NSMutableArray arrayWithCapacity:count];        for (int i = 0; i < count ; i++)    {        objc_property_t property = properties[i];        const char* propertyName =property_getName(property);        [propertiesArray addObject: [NSString stringWithUTF8String:propertyName]];    }        free(properties);        return propertiesArray;}/** *  获取对象的所有方法 */-(NSArray *)getAllMethods{    unsigned int count_f =0;    //获取方法链表    Method* methodList_f = class_copyMethodList([self class],&count_f);        NSMutableArray *methodsArray = [NSMutableArray arrayWithCapacity:count_f];        for(int i=0;i<count_f;i++)    {        Method temp_f = methodList_f[i];        //方法的调用地址        IMP imp_f = method_getImplementation(temp_f);        //方法        SEL name_f = method_getName(temp_f);        //方法名字符串        const char* name_s =sel_getName(method_getName(temp_f));        //参数数量        int arguments = method_getNumberOfArguments(temp_f);        //返回方法的参数和返回值的描述的字串        const char* encoding =method_getTypeEncoding(temp_f);        NSLog(@"方法名：%@,参数个数：%d,编码方式：%@",[NSString stringWithUTF8String:name_s],              arguments,[NSString stringWithUTF8String:encoding]);                NSString *methodStr = NSStringFromSelector(name_f);        [methodsArray addObject:methodStr];            }    free(methodList_f);        return methodsArray;}
