Hello!id you solve that problem? I encountered the same problem.

[jueyi1127]

* Terminating app due to uncaught exception 'NSInternalInconsistencyException', reason: 'This luminance source does not support cropping.' * First throw call stack: (0x180e6adb0 0x1804cff80 0x1000de6b4 0x1001036e0 0x1000dfd94 0x1000df7fc 0x10002d834 0x1000c0420 0x1005a9a7c 0x1005a9a3c 0x1005af4e4 0x180e20d50 0x180e1ebb8 0x180d48c50 0x182630088 0x186032088 0x1000333a0 0x1808e68b8) libc++abi.dylib: terminating with uncaught exception of type NSException

This is the code

UIImage *image = [UIImage imageWithCGImage:capture.lastScannedImage];

UIImageWriteToSavedPhotosAlbum(image,nil,nil,nil);

ZXCGImageLuminanceSource *source = [[ZXCGImageLuminanceSource alloc] initWithCGImage:image.CGImage];
ZXBinaryBitmap *bitmap = [ZXBinaryBitmap binaryBitmapWithBinarizer:[ZXHybridBinarizer binarizerWithSource:source]];

ZXDecodeHints *hints = [ZXDecodeHints hints];
hints.tryHarder = YES;

ZXMultiFormatReader *reader = [ZXMultiFormatReader reader];
ZXGenericMultipleBarcodeReader *multiReader = [[ZXGenericMultipleBarcodeReader alloc] initWithDelegate:reader];

NSError *error = nil;
NSArray *results = [multiReader decodeMultiple:bitmap hints:hints error:&error];

for (ZXResult *result2 in results) {
    NSLog(@"Decoded barcode %@", result2.text);
}

---

It fails in the creation of the NSArray *results, I can see the image saved fine to the photoalbum so I know the image is there so I don't understand why it crashes
