我正在尝试创建一个UITableViewController允许用户UIButton在导航栏中按 a 的方法，输入他们的数据，即名字和姓氏，然后控制器将此数据放入新的UITableViewCell. 我已经为此工作了大约一个星期，似乎有无穷无尽的问题。我将非常感谢有人帮助我完成它，因为我到处搜索但无济于事。
到目前为止，我有以下内容：

NSMutableArray *_objects;
}
@property (nonatomic, strong) NSArray *tableData;
@end
@implementation guestlistViewController
@synthesize tableData;

{
if ([[UIDevice currentDevice] userInterfaceIdiom] == UIUserInterfaceIdiomPad) {

我很确定我尝试了多少种不同的方法，它是几种不同方法的大量混合。我对 iOS 编程真的很陌生，所以希望它是可以挽救的：P
