点击按钮,将self.imageView上面的image内容保存到本地相册,并指定判断保存成功与否的方法imageSavedToPhotosAlbum:didFinishSavingWithError:contextInfo:
- (IBAction)saveImageToAlbum:(id)sender {
UIImageWriteToSavedPhotosAlbum(self.imageView.image, self, @selector(imageSavedToPhotosAlbum:didFinishSavingWithError:contextInfo:), nil);
}
实现imageSavedToPhotosAlbum:didFinishSavingWithError:contextInfo:方法
- (void)imageSavedToPhotosAlbum:(UIImage *)image didFinishSavingWithError:(NSError *)error contextInfo:(void *)contextInfo
{
NSString *message = @"呵呵";
if (!error) {
message = @"成功保存到相册";
}else
{
message = [error description];
}
NSLog(@"message is %@",message);
}
这些代码很简单,如果没有错误的话就提示“成功保存到相册”,如果保存失败的话,那么就输出错误信息[error description]。
