我看到TZImagePickerController里面已经修复了瞬间内存过高的问题，但是我们app在使用这个库的时候，快速选择几张图片的瞬间还是出现内存暴增的问题（50M-100多M），但不是每次选择图片都有内存暴增，如果多试几次，有时还会出现暴增，我们线上使用的版本是1.9.8版本。

使用： NSInteger seletMaxImages = kMaxImageUploat - self.vm.imageArray.count; TZImagePickerController *imagePickerVc = [[TZImagePickerController alloc] initWithMaxImagesCount:seletMaxImages delegate:self]; imagePickerVc.showSelectBtn = YES; // 一直展示选择按钮，防止最大可选图片为1时，三方库内部会隐藏选择按钮 imagePickerVc.allowPickingVideo = NO; // 不能选择视频 imagePickerVc.allowTakePicture = NO; // 内部拍照按钮隐藏 [self presentViewController:imagePickerVc animated:YES completion:nil];

回调： // 返回选择的图片

(void)imagePickerController:(TZImagePickerController )picker didFinishPickingPhotos:(NSArray )photos sourceAssets:(NSArray *)assets isSelectOriginalPhoto:(BOOL)isSelectOriginalPhoto {

NSMutableArray *images = [NSMutableArray arrayWithCapacity:photos.count];

if (images.count > 0) {
```
[self.vm.cmd_UpdateAwardAndHonerImages execute:images];
```
} }

我用的测机是： 6plus 10.3.2
5s 11.0.1
