代码很简单只有一句话
不多说上代码:
<span style="font-size:24px;">UIImage *newImage = UIGraphicsGetImageFromCurrentImageContext();
// 保存图片到指定的路径
NSData *data = UIImagePNGRepresentation(newImage);
[data writeToFile:@"/Users/userName/Desktop/myShaoNv.png" atomically:YES];
</span>
<span style="font-size:24px;"> // 保存image 到相册中
UIImageWriteToSavedPhotosAlbum(newImage, self, @selector(imageSavedToPhotosAlbum:didFinishSavingWithError:contextInfo:), nil);
// 保存到相册的代理方法, 判断保存的结果是否成功还是失败的信息
// 实现imageSavedToPhotosAlbum:didFinishSavingWithError:contextInfo:
- (void)imageSavedToPhotosAlbum:(UIImage *)image didFinishSavingWithError:(NSError *)error contextInfo:(void *)contextInfo
{
NSString *message = @"保存照片";
if (!error) {
message = @"保存成功";
} else
{
message = [error description];
}
NSLog(@"message is %@", message);
}
</span>
