wallet的前身为passbook，2015年WWDC大会苹果正式改名wallet，passbook是苹果2012年iOS6开放出来的新功能.可以帮助用户管理五种类型（Boarding passes（登机牌），Coupons（优惠券），Store cards（购物卡），Event tickets（入场券），Generic（通用卡））的票据

在iOS中一个Pass其实就是一个.pkpass文件，事实上它是一个Zip压缩包，只是这个压缩包要按照一定的目录结构来设计
如何创建一个Pass可以参考Apple的文档

-(void)addPassbookView:(NSData *)date{
    NSError *error = nil;
    BOOL passEnbale = [PKPassLibrary isPassLibraryAvailable];//检查pass是否可用
    if (![PKPassLibrary isPassLibraryAvailable]) {//
        dispatch_async(dispatch_get_main_queue(), ^{
            //[[WaitDialogFullS sharedWaitDialog] endLoading];
            [[[UIAlertView alloc] initWithTitle:@"Error"
                                        message:@"PassKit not available"
                                       delegate:nil
                              cancelButtonTitle:GDLocalizedString(@"jpyd_ok")
                              otherButtonTitles: nil] show];
        });
        return;
    }
    
    if (passEnbale) {
        PKPass *onePass = [[PKPass alloc] initWithData:date error:&error];
        if (error) {
            dispatch_async(dispatch_get_main_queue(), ^{

                [alert show];
                [alert release];
            });
            return ;

            ChinaEastViewController *app = [ChinaEastViewController sharedBankcommViewController];
            //Application tried to present a nil modal view controller on target .修改听云，李良
