直接用iPhoneX截图后是没有圆角和刘海的，就像下面这样。
其实加圆角和刘海也很简单
第一步：截屏
第二步：打开我这个软件，并选取图片库中的那张图
第三步：添加圆角，刘海
第四步：将做好的图片保存到相册
还需要下边这张刘海的图片
可以上代码了（目前原图是固定的，没有从图片库选取）

btn.frame = CGRectMake(10, 44, 350, 758);
btn.frame = CGRectMake(0, 0, 375, 812);
[btn setBackgroundImage:[UIImage imageNamed:@"IMG_3655.PNG"] forState:UIControlStateNormal];
//添加圆角
btn.layer.cornerRadius = 35 ;
btn.layer.borderColor = [UIColor blackColor].CGColor;
btn.layer.borderWidth = 2;
[self.view addSubview:btn];
btn.backgroundColor = [UIColor whiteColor];
btn.clipsToBounds = YES;
//添加刘海
UIImageView *imageView = [[UIImageView alloc]initWithImage:[UIImage imageNamed:@"liuhai.png"]];
imageView.frame = CGRectMake(70, 0, 222, 28);
[btn addSubview:imageView];
self.view.backgroundColor = [UIColor clearColor];
//截图保存到相册
dispatch_after(dispatch_time(DISPATCH_TIME_NOW, (int64_t)(1 * NSEC_PER_SEC)), dispatch_get_main_queue(), ^{
[self saveBtnAction:nil];
});
}
-(void)saveBtnAction:(UIButton *)sender{
[self requestAuthorizationStatus];
}
//查看权限
- (void)requestAuthorizationStatus
{
[PHPhotoLibrary requestAuthorization:^(PHAuthorizationStatus status){
dispatch_async(dispatch_get_main_queue(), ^{
switch (status) {
case PHAuthorizationStatusAuthorized:
{
[self cutScreen];
break;
}
default://Denied
{
break;
}
}
});
}];
}
//截屏
-(void)cutScreen{
UIGraphicsBeginImageContextWithOptions(self.view.bounds.size, YES, 0.0);
//2.获取当前图形上下文
CGContextRef ctx = UIGraphicsGetCurrentContext();
//3.获取需要截取的view的layer
[self.view.layer renderInContext:ctx];
//4.从当前上下文获取图片
UIImage *image = UIGraphicsGetImageFromCurrentImageContext();
//5.关闭图形上下文
UIGraphicsEndImageContext();
//6.把图片保存到相册
UIImageWriteToSavedPhotosAlbum(image, self, @selector(image:didFinishSavingWithError:contextInfo:), NULL);
}
//保存成功后回调
-(void)image:(UIImage *)image didFinishSavingWithError:(NSError *)error contextInfo:(void *)contextInfo{
NSString *msg = nil;
if (error) {
msg = @"图片保存失败";
}else{
msg = @"图片保存成功";
}
UIAlertView *alertView = [[UIAlertView alloc] initWithTitle:@"提示" message:msg delegate:self cancelButtonTitle:@"确定" otherButtonTitles:nil, nil];
[alertView show];
}

效果图是
