建议[UIApplication sharedApplication]相关的全局变量，在viewWillAppear的时候设置并备份原始的配置，viewDidDisappear的时候还原

选择原图跟不选择原图有什么区别呢？assets这个数组里装着什么?

1. 如果设置imagePicker.allowPickingVideo = NO;
   在相机胶卷中就不应该出现视频，应该过滤掉。
2. 选择两张图片后，进入预览，在预览界面再将两张图片取消选中，确定按钮可以点击，点击后会选择一张图片（应该一张图片都没有。）

3.还有一点：
在getPhotoWithAsset:photoWidth:completion:函数中，
CGImageRef thumbnailImageRef = alAsset.aspectRatioThumbnail;这句如果在ios6.0平台，缩略图会很模糊，感觉改为：CGImageRef thumbnailImageRef = alAsset.thumbnail;比较合适。

你好，我想把图片的选中状态加到里面，就是选完图片再进去的时候可以看到我之前选中了哪些图片，

当然这是我们的测试人员发现的问题，实在是不好意思，又提了一个小小的问题 我的做法是加了一个小方法 真的感谢您！

代码修改的是这里
@implementation TZAlbumPickerController

• (void)viewWillAppear:(BOOL)animated {
  [super viewWillAppear:animated];

  TZImagePickerController *imagePickerVc = (TZImagePickerController *)self.navigationController;
  [imagePickerVc mt_hideProgressHUD];

  if (_albumArr) return;
  [self configTableView];
  }

• (void)mt_hideProgressHUD {
  if (_progressHUD) {
  [_HUDIndicatorView stopAnimating];
  [_progressHUD removeFromSuperview];
  }
  }

传回来的是一张img，那视频的数据呢，求解答下

由于您在UIView+Layout这个Category中定义了UIView的left、top等属性，与Mansory（封装Autolayout的框架）中定义产生了冲突，导致我不得不重构您的代码来使用

建议不要采用这个Category，或者将里面的属性改为较复杂的名称。因为在多组件运用的工程中很容易出现类似的冲突，而兼容性是您的组件需要考虑的问题

最后多谢您的分享，期待您在下个版本中修复此问题

• (void)getPhotoWithAsset:(id)asset photoWidth:(CGFloat)photoWidth completion:(void (^)(UIImage *, NSDictionary *, BOOL isDegraded))completion
  这个方法

TZImageManager.m文件

/// Get photo bytes 获得一组照片的大小
- (void)getPhotosBytesWithArray:(NSArray *)photos completion:(void (^)(NSString *totalBytes))completion {
__block NSInteger dataLength = 0;
for (NSInteger i = 0; i < photos.count; i++) {
    TZAssetModel *model = photos[i];
    if ([model.asset isKindOfClass:[PHAsset class]]) {
        [[PHImageManager defaultManager] requestImageDataForAsset:model.asset options:nil resultHandler:^(NSData * _Nullable imageData, NSString * _Nullable dataUTI, UIImageOrientation orientation, NSDictionary * _Nullable info) {
            if (model.type != TZAssetModelMediaTypeVideo) dataLength += imageData.length;
            if (i >= photos.count - 1) {
                NSString *bytes = [self getBytesFromDataLength:dataLength];
                if (completion) completion(bytes);
            }
        }];
    } else if ([model.asset isKindOfClass:[ALAsset class]]) {
        ALAssetRepresentation *representation = [model.asset defaultRepresentation];
        if (model.type != TZAssetModelMediaTypeVideo) dataLength += (NSInteger)representation.size;
        if (i >= photos.count - 1) {
            NSString *bytes = [self getBytesFromDataLength:dataLength];
            if (completion) completion(bytes);
        }
    }
}
}

这样写有问题，由于requestImageDataForAsset默认是异步调用，当选择多张图片的时候，我们无法判断哪个请求先完成，假如选了5张图片，第五张求完成了，但是可能第一张请求还未完成，所以得到的照片大小和出错。
你可以采用手动开子线程，然后同步调用requestImageDataForAsset，比如：

+ (void)requestImageDataForAsset:(NSArray<PHAsset *>*)assets resultHandle:(void(^)(NSString * length))resultHandler{
 __block NSInteger totleLength = 0;
//采用组队列，判断请求是否全部完成
dispatch_group_t group = dispatch_group_create();
dispatch_group_async(group, dispatch_get_global_queue(DISPATCH_QUEUE_PRIORITY_DEFAULT, 0), ^{
    PHImageRequestOptions *options = [[PHImageRequestOptions alloc] init];
    options.synchronous = YES;
    for (int i = 0 ;  i < assets.count; i++) {
        [[PHImageManager defaultManager] requestImageDataForAsset:assets[i] options:options resultHandler:^(NSData * _Nullable imageData, NSString * _Nullable dataUTI, UIImageOrientation orientation, NSDictionary * _Nullable info) {
            totleLength += imageData.length;
        }];
    }
});
dispatch_group_notify(group, dispatch_get_global_queue(DISPATCH_QUEUE_PRIORITY_DEFAULT, 0), ^{
    NSString *bytes;
    if (totleLength >= 0.1 * (1024 * 1024)) {
        bytes = [NSString stringWithFormat:@"%0.1fM",totleLength/1024/1024.0];
    } else if (totleLength >= 1024) {
        bytes = [NSString stringWithFormat:@"%0.0fK",totleLength/1024.0];
    } else {
        bytes = [NSString stringWithFormat:@"%zdB",totleLength];
    }
    //回到主线程刷新页面
    dispatch_async(dispatch_get_main_queue(), ^{
        resultHandler(bytes);
    });
});
}

这个图片选择的时候，第一次选八张，发表界面预览8张，第二次选超过1张，发表界面就回超过9张，
你的picker没有记录总选择数应该9张，选过之后，应该记录还剩几张还能选，不然就会出现上述问题

图片上传时.如果选择的是landscape(横屏的)图片时,会发生180度的颠倒,最后取到的图是180度的反向图片

一张图片能多次被选择，😄辛苦了

bug：
1.presentViewController的时候不会自动跳转到相机胶卷里，但是你的demo可以，看了下里面的代码实现，是根据名字来匹配的，这里面有坑。
2.demo里面将imagePickerVc.allowPickingVideo =NO;
设置成只能选图片之后，跳转出来的依旧可以选择视频

建议将NavigationController滑动返回的手势加上

在Ios8.4下图片大概三百多张，来回滑动，会收到内存警告，然后崩溃。

希望更新cocoapods集成，现在不能用而且还不是最新的

(づ￣ 3￣)づ么么哒

你好，当我选择原图时，点击确定，返回发现并不是原图的大小呢？

第二次进入相册时，怎么默认选中第一次已选的图片

点击选取原图，但我去看大小的时候，没变化，是不是只点击原图只看得到原图大小，而拿到的还是编辑过的图，希望能看到并回复我一下

这几天尝试pods集成，但是老是提示失败，希望支持那赞一个楼煮啥时候能支持来？

用的8.3.1的4s手机加载的图片上传到服务器时图片向左旋转了90度

TZPhotoPreviewController.m 中 cellForItemAtIndexPath 代理方法
__weak typeof(_naviBar) weakNaviBar = _naviBar; __weak typeof(_naviBar) weakToolBar = _naviBar;
写重了，应该是_toolBar。楼主写的很棒。辛苦了！

相机和相册不能同时支持。
只能在相册中选择，如果相机和相册同时支持就好。

请教一下, 怎么能和系统相册一样,按照时间顺序进行排列?

在presented的Controller中再次present TZImagePickerController,点击取消的时候会把上一级的也dismiss。
完成和取消没有必要调用self.navigationController dismissViewControllerAnimated吧

希望优化

PHImageRequestOptions *option = [[PHImageRequestOptions alloc]init];
option.networkAccessAllowed = YES;

    [[PHImageManager defaultManager] requestImageForAsset:asset targetSize:CGSizeMake(pixelWidth, pixelHeight) contentMode:PHImageContentModeAspectFit options:option resultHandler:^(UIImage * _Nullable result, NSDictionary * _Nullable info) {
        BOOL downloadFinined = (![[info objectForKey:PHImageCancelledKey] boolValue] && ![info objectForKey:PHImageErrorKey]);
        if (downloadFinined) {
            if (completion) completion(result,info,[[info objectForKey:PHImageResultIsDegradedKey] boolValue]);
        }
    }];

PHImageRequestOptions 设置为 允许网络图片下载 就可以了

collectionView 3列时，来回拖动会有错乱感，刷新不及时

比如我设置了limit=9 我先选择了7张图 然后返回 然后继续选择 可以选择大于9张 就能绕过9张图的限制

如果加载的图片是iCloud时，查看大图时是灰屏的，并且点击确认之后，那个加载指示器会一直存在视图上

就是选择后，进入预览界面，然后不选择，但是最后还是选择，这个有bug。

present进去之后 是相册的列表 并不是照片列表 然后点击选择一个相册之后，没有这个相册里面的照片..一片空白.怎么解决？？

崩溃在TZImagePickerController类里的41行位置.
appearanceWhenContainedInInstancesOfClasses"这个方法是9.0之后才有的,但是你的判断却是让它在7.0之后的系统上执行,所以才导致崩溃

UIBarButtonItem *barItem = [UIBarButtonItem appearanceWhenContainedInInstancesOfClasses:@[[TZImagePickerController class]]];

在pod下

添加方法后运行出现如下错误

*** Terminating app due to uncaught exception 'NSInternalInconsistencyException', reason: 'Could not load NIB in bundle: 'NSBundle <xxx.app> (loaded)' with name 'TZAlbumCell''

报错地方

TZAlbumCell *cell = [tableView dequeueReusableCellWithIdentifier:@"TZAlbumCell"];

猜测

检查了下nib的名字和imagepiccontroller 中引用的名字，没有错误，难道是其他问题引起的？

选择原图，再取消，在选择 反复多次 会发现有时候总图片大小会不一样
比如一共9.7M的图片，多点几次会出现6.4M，类似这样的情况

我用pods集成的 项目开启就蹦了 - - 问题是我还没调用你的 只是单纯的集成而已 它蹦的信息是这个
dyld`dyld_fatal_error: -> 0x120069098 <+0>: brk

但是手动集成就没有事

用的swift，集成后所有XIB/图片资源打包进 TZImagePickerController.framework 中

但是运行时会只在 app 根目录下寻找资源，导致找不到资源而崩溃

滑动的时候明显卡顿，cpu飙到一百多

第一是修正转向的时候导致图片重绘，丢失了原来拍照的exif信息，第二是重绘之后图片尺寸变大了很多

不知道是什么原因，5s上没有这种现象

正在处理。。。等太久，然后那个提示框就一直在那了，也去不了了，我那边的代码应该也没耗时那么长啊，还有imagePickerControllerDidCancel这个方法名重复了？

result = [self fixOrientation:result];纠正图片方向时会导致图片占用内存暴增，希望大神想到更好的方案解决内存占用高的问题
