iOS runtime 动态获取属性存放在数组

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]];
    }
