ios - 无法理解崩溃日志部分应用转发器来关闭 #1

Question

我遇到了曲棍球应用程序崩溃问题

Thread 0 Crashed:

在 PhotoLibraryImageLoader.swift 中

static func image(from assest:PHAsset,size:CGSize,success:@escaping (_ image:UIImage) -> Void) {
        let option = PHImageRequestOptions()
        option.isSynchronous = false
        option.deliveryMode = .highQualityFormat
        PHImageManager.default().requestImage(for: assest, targetSize: size, contentMode: .aspectFill, options: option) { (image, attributes) in
            success(image!) // Crash line  PhotoLibraryImageLoader.swift:28
        }
 }

如果可选(图像!)存在问题，崩溃日志应该有所不同(例如意外发现 nil..)

这里部分申请转发器关闭是什么意思

有人可以帮我了解一下吗？

Answer 1

图像不可用导致崩溃(需要从服务器下载)

为此，请在选项中添加一行

    option.isNetworkAccessAllowed = true

希望对大家有帮助
