[置顶] iOS长按识别图中二维码

直接上代码  基于 zbar

#pragma mark -------判断是否为二维码
- (void)isPinCodeWithImage:(UIImage *)image{
ZBarReaderController* read = [ZBarReaderController new];
CGImageRef cgImageRef = image.CGImage;
ZBarSymbol* symbol = nil;
for(symbol in [read scanImage:cgImageRef])
break;
_pincodeURL = symbol.data;
UIActionSheet *actionSheet;
if ([symbol.data hasPrefix:@"http"]) {
actionSheet = [[UIActionSheet alloc] initWithTitle:nil delegate:self cancelButtonTitle:@"取消" destructiveButtonTitle:@"保存图片" otherButtonTitles:@"扫二维码", nil];
} else {
actionSheet = [[UIActionSheet alloc] initWithTitle:nil delegate:self cancelButtonTitle:@"取消" destructiveButtonTitle:@"保存图片" otherButtonTitles:nil, nil];
}
[actionSheet showInView:self.superview];
}
