iOS 运行时获取类的所有属性

转自iOS 运行时获取类的所有属性

一、扩展NSArray分类

NSArray+Extension.h:

#import <Foundation/Foundation.h>

@interface NSArray (Extension)

+ (instancetype)getProperties:(Class)cls;

@end

NSArray+Extension.m:

#import "NSArray+Extension.h"
#import <objc/runtime.h>// 导入运行时文件
@implementation NSArray (Extension)

//返回当前类的所有属性
+ (instancetype)getProperties:(Class)cls{

    // 获取当前类的所有属性
    unsigned int count;// 记录属性个数
    objc_property_t *properties = class_copyPropertyList(cls, &count);
    // 遍历
    NSMutableArray *mArray = [NSMutableArray array];
    for (int i = 0; i < count; i++) {

        // An opaque type that represents an Objective-C declared property.
        // objc_property_t 属性类型
        objc_property_t property = properties[i];
        // 获取属性的名称 C语言字符串
        const char *cName = property_getName(property);
        // 转换为Objective C 字符串
        NSString *name = [NSString stringWithCString:cName encoding:NSUTF8StringEncoding];
        [mArray addObject:name];
    }

    return mArray.copy;
}
