runtime获取类属性列表和方法列表

获取对象的所有属性

/* 获取对象的所有属性 */
+(NSArray *)getAllProperties
{
    u_int count;
    // 传递count的地址过去 &count
    objc_property_t *properties  =class_copyPropertyList([self class], &count);
    //arrayWithCapacity的效率稍微高那么一丢丢
    NSMutableArray *propertiesArray = [NSMutableArray arrayWithCapacity:count];

    for (int i = 0; i < count ; i++)
    {
        //此刻得到的propertyName为c语言的字符串
        const char* propertyName =property_getName(properties[i]);
        //此步骤把c语言的字符串转换为OC的NSString
        [propertiesArray addObject: [NSString stringWithUTF8String: propertyName]];
    }
    //class_copyPropertyList底层为C语言，所以我们一定要记得释放properties
    // You must free the array with free().
    free(properties);

    return propertiesArray;
}  ```
#### 获取对象所有方法

/* 获取对象的所有方法 */
+(NSArray )getAllMethods
{
unsigned int methodCount =0;
Method methodList = class_copyMethodList([self class],&methodCount);
NSMutableArray *methodsArray = [NSMutableArray arrayWithCapacity:methodCount];

for(int i=0;i

} ```

获取对象的所有属性和属性内容

/* 获取对象的所有属性和属性内容 */
+ (NSDictionary *)getAllPropertiesAndVaules:(NSObject *)obj
{
    NSMutableDictionary *propsDic = [NSMutableDictionary dictionary];
    unsigned int outCount;
    objc_property_t *properties =class_copyPropertyList([obj class], &outCount);
    for ( int i = 0; i
