可以通过以下代码实现截屏,然后保存到相册。
-(void)savePicture{
1.传入要截屏的view,并转换为UIImage
UIImage * image = [self captureImageFromView:self.view];
2.写入相册(不要忘记加info中添加相册的写入权限!!!)
ALAssetsLibrary * library = [ALAssetsLibrary new];
NSData * data = UIImageJPEGRepresentation(image, 1.0);
[library writeImageDataToSavedPhotosAlbum:data metadata:nil completionBlock:nil];
}
-(UIImage *)captureImageFromView:(UIView *)view
{
CGRect screenRect = [view bounds];
UIGraphicsBeginImageContextWithOptions(screenRect.size, NO, 0.0);//原图
CGContextRef ctx = UIGraphicsGetCurrentContext();
[view.layer renderInContext:ctx];
UIImage * image = UIGraphicsGetImageFromCurrentImageContext();
return image;
}
