ZBAR read static UIImage (No Camera preview)

Question

Im building an application for IPad and I am using ZBar.

The image containing the barcode data is a UIImage called TempUIImage. How can I use ZBar to detect the value of the barcode and it's location.

Note: I don't want want the camera preview at all as the TempUIImage is an UIImage that should be taken from another application.

I also have this issue.. can any one help? – Baig Feb 17 '14 at 06:32 — Baig, Feb 17 '14 at 06:32

You can use ZBarImageScanner class. Here there is a complete documentation ZBarImageScanner

Here there is an example on how to use it (I don't tested it on device):

ZBarImageScanner *scanner = [[ZBarImageScanner alloc]init];
NSInteger resultsnumber = [scanner scanImage:yourUIImage];
if(resultsnumber > 0){
    ZBarSymbolSet *results = scanner.results;
    //do whatever u want with results!!!
}

i was also facing this issue in one of my project, i solved the issue by making an object of ZBarImageScanner as

ZBarImageScanner *scanner

See my answer at Scaning static UIImage using ios ZBar SDK for details
