Question

我正在尝试将MWPhotoBrowser包含在我的项目中

当它在样品中使用时，它工作正常。
但是当一个新的viewcontroller从MWPhotoBrowser子类化时，除了空的黑色主题外，不会加载照片。
不会调用委托方法。由于控制器是MWPhotoBrowser的子类，我假设不需要明确设置它。
使用Storyboard并设置其中的nib类。

.h文件

@interface MDRPhotoViewerController : MWPhotoBrowser
{
    NSMutableArray *_selections;
}
@property (nonatomic, strong) NSMutableArray *photos;
@property (nonatomic, strong) NSMutableArray *thumbs;
@property (nonatomic, strong) NSMutableArray *assets;
@property (nonatomic, strong) NSMutableIndexSet *optionIndices;
@property (nonatomic, strong) UITableView *tableView;

@property (nonatomic, strong) ALAssetsLibrary *ALAssetsLibrary;

- (void)loadAssets;
@end

**。m file **

- (void)viewWillAppear:(BOOL)animated
{
   NSMutableArray *photos = [[NSMutableArray alloc] init];
    NSMutableArray *thumbs = [[NSMutableArray alloc] init];
//mwphotobrowser options setup
    BOOL displayActionButton = YES;
    BOOL displaySelectionButtons = NO;
    BOOL displayNavArrows = NO;
    BOOL enableGrid = YES;
    BOOL startOnGrid = NO;
    BOOL autoPlayOnAppear = NO;

    //loading data
    NSArray *photosDataArray = [MDRDataController GetPhotos]; //creating array
    for (NSString *urlString in photosDataArray) { //Formating the data source for images
        NSString *urlFullString = [NSString stringWithFormat:@"%@%@",KBASEURL,urlString];
        //Photos
        [photos addObject:[MWPhoto photoWithURL:[NSURL URLWithString:urlFullString]]];
        //thumbs
        [thumbs addObject:[MWPhoto photoWithURL:[NSURL URLWithString:urlFullString]]];

    }
    // Options
    self.photos = photos;
    self.thumbs = thumbs;

    // Create browser
    self.displayActionButton = displayActionButton;
    self.displayNavArrows = displayNavArrows;
    self.displaySelectionButtons = displaySelectionButtons;
    self.alwaysShowControls = displaySelectionButtons;
    self.zoomPhotosToFill = YES;
    self.enableGrid = enableGrid;
    self.startOnGrid = startOnGrid;
    self.enableSwipeToDismiss = NO;
    self.autoPlayOnAppear = autoPlayOnAppear;
    [self setCurrentPhotoIndex:0];

    // Test custom selection images
    //    browser.customImageSelectedIconName = @"ImageSelected.png";
    //    browser.customImageSelectedSmallIconName = @"ImageSelectedSmall.png";

    // Reset selections
    if (displaySelectionButtons) {
        _selections = [NSMutableArray new];
        for (int i = 0; i < photos.count; i++) {
            [_selections addObject:[NSNumber numberWithBool:NO]];
        }
    }
    self.title = @"Phots";
    //[self reloadData];
}

已执行调试

考虑mwphotobrowser的图像模板，尝试重新加载代码。在viewwillappear和viewdidload之间移动代码。

MWPhotoBrowser不支持这种方式，还是我做错了？

对于那些后来偶然发现的人......

如果你看看MWPhotoBrowser.m，你会看到各种初始化器：

- (id)init {
if ((self = [super init])) {
    [self _initialisation];
}
return self;
}

- (id)initWithDelegate:(id <MWPhotoBrowserDelegate>)delegate {
    if ((self = [self init])) {
        _delegate = delegate;
    }
    return self;
}

- (id)initWithPhotos:(NSArray *)photosArray {
    if ((self = [self init])) {
        _fixedPhotosArray = photosArray;
    }
    return self;
}

- (id)initWithCoder:(NSCoder *)decoder {
    if ((self = [super initWithCoder:decoder])) {
        [self _initialisation];
    }
    return self;
}

问题是没有awakeFromNib初始化程序。最简单的解决方案是分叉项目并创建awakeFromNib初始化器。
