iOS 获取一个类的所有方法

#import <objc/runtime.h>

#import <objc/message.h>

需要导入运行时头文件和消息发送文件

- (void)runTests

{

unsigned int count;

Method *methods = class_copyMethodList([self
class], &count);

for (int i =
0; i < count; i++)

{

Method method = methods[i];

SEL selector = method_getName(method);

NSString *name = NSStringFromSelector(selector);

//        if ([name hasPrefix:@"test"])

NSLog(@"方法
名字 ==== %@",name);

if (name)

{

//avoid arc warning by using c runtime

//            objc_msgSend(self, selector);

}

NSLog(@"Test '%@' completed successfuly", [name
substringFromIndex:4]);

}

}
