错误Passbook - PKZip签名

我运行代码，如下所述。当我收到文件（NSData）时，出现以下错误：错误Passbook - PKZip签名

"BOM could not extract archive: Couldn't read PKZip signature"

发生了什么？有没有人有这个问题，我该如何解决它？

NSString *url = [res objectForKey:@"url"]; 

    NSData *data = [[NSData alloc] initWithContentsOfURL:[NSURL URLWithString:url]]; if (nil != data) { 

    //init a pass library 
    PKPassLibrary* passLib = [[PKPassLibrary alloc] init]; 

    NSError *error; 

    //init a pass object with the data 
    PKPass *pass = [[PKPass alloc] initWithData:data error:&error]; 

    if(error) { 

    UIAlertView *alertView = [[UIAlertView alloc] initWithTitle:@"Error" message:[error localizedDescription] delegate:nil cancelButtonTitle:@"OK"otherButtonTitles:nil]; 
    [alertView show]; 

    } 

    //check if pass library contains this pass already 
    if([passLib containsPass:pass]) { 

     //pass already exists in library, show an error message 
     UIAlertView* alertView = [[UIAlertView alloc] initWithTitle:@"Pass Exists" message:@"The pass you are trying to add to Passbook is already present." delegate:nil cancelButtonTitle:@"OK" otherButtonTitles:nil]; 
     [alertView show]; 

    } else { 

     //present view controller to add the pass to the library 
     PKAddPassesViewController *vc = [[PKAddPassesViewController alloc] initWithPass:pass]; 
     [vc setDelegate:(id)self]; 
     [self presentViewController:vc animated:YES completion:nil]; 
    } 
}

听起来像是.pkpass包的问题，而不是您的代码。当您通过Safari，邮件附件或OSX中的传递查看器访问.pkpass包时，是否正确接收.pkpass包？你使用的是什么版本的iOS SDK？ – PassKit

假设您尝试使用来自connectionDidReceiveData方法的NSData对象，这是错误的。你应该积累NSData对象，直到connectionDidFinishLoading。

你应该做这样的事情：

-(void)connection:(NSURLConnection *)connection didReceiveData:(NSData *)data { 
    if (self.passData != nil) { 
     [self.passData appendData:data]; 
    } 
    else { 
     self.passData = [NSMutableData dataWithData:data]; 
    } 
} 

-(void)connectionDidFinishLoading:(NSURLConnection *)connection { 
    NSError *error; 
    PKPass *pass = [[PKPass alloc] initWithData:self.passData error:&error]; 
    //add pass 
    self.passData = nil; 
}

的问题是在该行

//init a pass object with the data 
    PKPass *pass = [[PKPass alloc] initWithData:data error:&error];

下载的数据被破坏。

如果你能够通过电子邮件/ Safari添加通行证，那么问题是由于NSData对象。

在我的情况下，pkpass文件的base64字符串值被接收到我转换为NSData对象的设备上。 PKPass对象能够读取我的通行证。下面是我使用的代码：

// dictionary contains base64string values of the pkpass file. 
for (NSString *key in [dictionary allKeys]) 
{ 
    NSError *error; 
    NSData *decodedData = [[NSData alloc] initWithBase64EncodedString:[dictionary valueForKey:key] options:0]; 
    NSString *decodedString = [[NSString alloc] initWithData:decodedData encoding:NSUTF8StringEncoding]; 

    PKPass *pass = [[PKPass alloc] initWithData:decodedData error:&error]; 
    [arrPasses addObject:pass]; 

} 
if ([arrPasses count] > 0) 
{ 
    PKAddPassesViewController *vc = [[PKAddPassesViewController alloc] initWithPasses:arrPasses]; 
    [self presentViewController:vc animated:YES completion:nil]; 
} 
else 
{ 
    NSLog(@"Passes not found"); 
}

希望这有助于！
