轉(zhuǎn)自iOS 運(yùn)行時(shí)獲取類的所有屬性

一、擴(kuò)展NSArray分類

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>// 導(dǎo)入運(yùn)行時(shí)文件
@implementation NSArray (Extension)

//返回當(dāng)前類的所有屬性
+ (instancetype)getProperties:(Class)cls{

    // 獲取當(dāng)前類的所有屬性
    unsigned int count;// 記錄屬性個(gè)數(shù)
    objc_property_t *properties = class_copyPropertyList(cls, &count);
    // 遍歷
    NSMutableArray *mArray = [NSMutableArray array];
    for (int i = 0; i < count; i++) {

        // An opaque type that represents an Objective-C declared property.
        // objc_property_t 屬性類型
        objc_property_t property = properties[i];
        // 獲取屬性的名稱 C語言字符串
        const char *cName = property_getName(property);
        // 轉(zhuǎn)換為Objective C 字符串
        NSString *name = [NSString stringWithCString:cName encoding:NSUTF8StringEncoding];
        [mArray addObject:name];
    }

    return mArray.copy;
}
