轉(zhuǎn)自iOS 運行時獲取類的所有屬性
一乳附、擴展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)入運行時文件
@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;
}
