DymicLib.h代码:

#import <Foundation/Foundation.h>
#import <UIKit/UIKit.h>
@interface DymicLib : UIViewController
@end

DymicLib.m代码

#import "DymicLib.h"
#import <UIKit/UIKit.h>
@implementation DymicLib
static void __attribute__  ((constructor)) initialize (void)
{
    NSLog(@"test1");  
    UIButton * btn = [[UIButton alloc] init];
    btn.frame = CGRectMake(20, 20, 70, 30);
    btn.backgroundColor = [UIColor redColor];
    [self.view  addSubview:btn];   --此处报错self没有定义,我该如何修改,才能实现添加按钮成功呢?谢谢.
}
@end

我知道如果是一个普通Project,放到viewDidLoad中即可,但在动态库中,如何实现呢?
感谢各位老师!
