有关属性的反射方法(是如何将康总的电池反射过来的)

康总的电池是这样的：

@interface MyBattery :NSObject

@property int statusBarBatteryCapacity;

。。。

+ (MyBattery *)sharedIntance;

@end

#import <Foundation/Foundation.h>

@interface CYBattery : NSObject

+ (int)cySharedIntance;

@end

#import "CYBattery.h"

@implementation CYBattery

+ (int)cySharedIntance

{

    Class myGetMAC = NSClassFromString(@"MyBattery");

    int temp;

    if (myGetMAC) 

    {

        id messageInstance = [myGetMAC performSelector:@selector(sharedIntance)];

        if (messageInstance) {

            temp = [messageInstance performSelector:@selector(statusBarBatteryCapacity)];   //切记这个地方直接statusBarBatteryCapacity就行 ，不能写成getStatusBarBatteryCapacity(原因不明)

        } else {

            temp = 0;

            NSLog(@"CYBattery: [MyBattery sharedIntance]方法执行失败");

        }

        

    }

    else

    {

        temp = 0;

        NSLog(@"CYBattery:获取第三方库文件失败,请添加libMyBattery.a");

    }

    return temp;

}

@end
