需要 #import <objc/runtime.h>
实现
NSMutableArray *allNames = [[NSMutableArray alloc] init];
///存储属性的个数
unsigned int propertyCount = 0;
///通过运行时获取当前类的属性
objc_property_t *propertys = class_copyPropertyList([self class], &propertyCount);
//把属性放到数组中
for (int i = 0; i < propertyCount; i ++) {
///取出第一个属性
objc_property_t property = propertys[i];
const char * propertyName = property_getName(property);
[allNames addObject:[NSString stringWithUTF8String:propertyName]];
}
