Ios 如何将NSMutableArray值共享给MFMailComposeViewController

我从数据库中获取值，并将这些值分配给NSMuatbleArray。然后将值数组共享到邮件中。如何与setMessgaeBody共享值：

if (sqlite3_prepare_v2(database, sql, -1, &statement, NULL) == SQLITE_OK) {
 // We "step" through the results - once for each row.
 while (sqlite3_step(statement) == SQLITE_ROW) {


 sk_code = [[NSString alloc] initWithUTF8String:
 (const char *) sqlite3_column_text(statement, 4)];


 NSLog(@"sk_code %@",sk_code);


 [product_sku_array addObject:sk_code];


  // To address
 NSArray *toRecipents = [NSArray arrayWithObject:@"test@gmail.com"];

 MFMailComposeViewController *mailController = [[MFMailComposeViewController alloc] init];

 //  mailController.mailComposeDelegate = self;

 [mailController setSubject:@"Test"];

 [mailController setMessageBody:product_sku_array isHTML:NO];

 [mailController setToRecipients:toRecipents];


 [self presentViewController:mailController animated:YES completion:nil];


 }

NSLog：

product_sku_array (
    123
)

 sk_code test1
 product_sku_array (
    123,
    test1
)
 temp inside is 123,test1

正确初始化阵列，然后使用

---

[mailController setMessageBody:[product_sku_array componentsJoinedByString:@“，“]isHTML:NO]

[mailController setMessageBody:

接受字符串参数，因此

获取NSMutableString并将每个数组对象附加到单个字符串中

像

字符串=[string appendString:[NSString stringWithFormat:%@，[array] 对象索引：i]]]

然后将该字符串设置为消息体，如

[mailController setMessageBody:string isHTML:NO]

---

我只从数组中获取第一个值。product_sku_数组（123，test1）我只得到123个值，没有得到test1nsstring*temp=[product_sku_数组组件通过字符串连接：@“，”；检查临时字符串并检查数组。如果临时状态良好，则使用[mailController setMessageBody:temp isHTML:NO]；
