想了解详谈iPhoneX截图怎样带的相关内容吗,_小呵呵在本文为您仔细讲解iPhoneX截图怎样带"刘海"和圆角的相关知识和一些Code实例,欢迎阅读和指正,我们先划重点:iPhoneX,截图,刘海,圆角,下面大家一起来学习吧。

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)

- (void)viewDidLoad {
 [super viewDidLoad];
 
 UIButton *btn = [[UIButton alloc]init];
 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];
}
@end
