Question

我有一个工作代码，但现在发现需要导入＆amp;通过电子邮件“打开”选项保存两个不同的Sqlite文件，我尝试使用UIAlertView创建不同的保存文件路径，但它似乎只能用一种方式

- (void)handleOpenURL:(NSURL *)urlx {
NSData *dbimport = [[NSData alloc] initWithContentsOfURL:urlx];
NSUserDefaults *defaults = [NSUserDefaults standardUserDefaults];
[defaults setObject:dbimport forKey:@"import"];
[defaults synchronize];
NSLog(@"import saved");
databaseName = @"svrStoreData2.sql";
NSString *documentsPath = [NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES) firstObject];
NSError *writeError = nil;
NSString *filePathx = [documentsPath stringByAppendingPathComponent:databaseName]; [dbimport writeToFile:filePathx atomically:YES];
if (writeError)
{
    NSLog(@"Error writing file: %@", writeError);
}
}

两个文件都有特定的文件名，所以我想知道我是否可以使用“if equal to string”＆amp;在我同步NSUserDefaults以提供两个文件路径保存选项

之后使用if语句

感谢您提前提供任何帮助

这是我的UIALertView尝试

UIAlertView *alertdata = [[UIAlertView alloc]
                    initWithTitle:@"What type of data do you want to import?"
                      message:@"Choose data type"
                    delegate:self
                     cancelButtonTitle:@"Import RM Name Data"
                     otherButtonTitles:@"Import Store Visit Data", nil];

NSInteger *buttonIndex = NULL;
NSLog(@"Button Index =%ld",(long)buttonIndex);
if (buttonIndex == 0)
{
}
else if (buttonIndex == 1)
{
    databaseExportName = @"export.sql";
       NSArray *pathssqlite3 = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
        NSString *pathssqliteDir2 = [pathssqlite3 objectAtIndex:0];
        filePathsqlite3 = [pathssqliteDir2 stringByAppendingPathComponent:databaseExportName];
       NSData *dbimport = [[NSData alloc] initWithContentsOfURL:urlx];
      NSMutableData *dbimport = [[NSMutableData alloc] initWithContentsOfURL:urlx];
        NSError *writeError = nil;
        [dbimport writeToFile:filePathsqlite3 atomically:YES];
       if (writeError)
      {
           NSLog(@"Error writing file: %@", writeError);
       } } [alertdata show];

仍然试图解决，希望这会起作用，但仍然无法破解它

 `- (void)handleOpenURL:(NSURL *)urlx {
NSData *dbimport = [[NSData alloc] initWithContentsOfURL:urlx];
NSUserDefaults *defaults = [NSUserDefaults standardUserDefaults];
[defaults setObject:dbimport forKey:@"import"];
[defaults synchronize];
NSLog(@"import saved");
if([[urlx absoluteString] isEqualToString:@"svrStoreData2.sql"])
{
     NSLog(@"If statement called");
    //
    databaseName = @"svrStoreData2.sql";
    NSString *documentsPath = [NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES) firstObject];
    NSError *writeError = nil;
    NSString *filePathx = [documentsPath stringByAppendingPathComponent:databaseName];
    [dbimport writeToFile:filePathx atomically:YES];
    if (writeError)
    {
        NSLog(@"Error writing file: %@", writeError);
    }
    //
    else {

        databaseExportName = @"export.sql";
        NSString *documentsPathy = [NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES) firstObject];
         NSError *writeError = nil;
        NSString *filePathy = [documentsPathy stringByAppendingPathComponent:databaseExportName];
        [dbimport writeToFile:filePathy atomically:YES];

           if (writeError)
           {
               NSLog(@"Error writing file: %@", writeError);
           }
        NSLog(@"If statement Not called");
    }
}

}

- (void)alertView:(UIAlertView *)alertView clickedButtonAtIndex(NSInteger)buttonIndex {

    if ([alertView tag] == 14)

    {

        if (buttonIndex == 1)

        {

            [self reviewSave];

        }
    }


    if ([alertView tag] == 11) {

        if (buttonIndex == 1)

        {


            NSDictionary *defaultsDictionary = [[NSUserDefaults standardUserDefaults] dictionaryRepresentation];
            for (NSString *key in [defaultsDictionary allKeys]) {
                [[NSUserDefaults standardUserDefaults] removeObjectForKey:key];}
        }

    }

解决了问题，我有另一个UIAlert，所以通过添加标签排序

absoluteString“handleOpenURL”匹配电子邮件附件名称？
