Question

好的，所以我可能真的很喜欢编程，但是我已经有一段时间没有解决这个问题了，也无法解决这个问题。我有可扩展 tableView动态＆＃34;添加＆＃34; 和＆＃34;删除＆＃34; 行

两个问题：
1）我可以在单元格中加载textFields和labels的唯一方法是展开tableView并单击加载按钮。我保存textFields和labels的代码位于expandingcell.m而不是viewController.m。我希望我的信息在启动时加载。

2）如果我保存单元格信息，它会保存我在每个单元格中的信息，所以当我加载它时，每单个单元格将加载相同的东西，当我单击加载按钮。任何帮助都会非常感激我在这个上花了无数个小时

  #import "ExpandingCell.h"

@implementation ExpandingCell
@synthesize DateLabel, CourseLabel, Date, Course, Score, Par, Putts, GIR;

- (IBAction)Save:(id)sender
{
    NSString *saveString = Date.text;
    NSUserDefaults *defaults = [NSUserDefaults standardUserDefaults];
    [defaults setObject:saveString forKey:@"saveString"];
    [defaults synchronize];

    NSString *saveString1 = Course.text;
    NSUserDefaults *defaults1 = [NSUserDefaults standardUserDefaults];
    [defaults1 setObject:saveString1 forKey:@"saveString1"];
    [defaults1 synchronize];

    NSString *saveString2 = Score.text;
    NSUserDefaults *defaults2 = [NSUserDefaults standardUserDefaults];
    [defaults2 setObject:saveString2 forKey:@"saveString2"];
    [defaults2 synchronize];

    NSString *saveString3 = Par.text;
    NSUserDefaults *defaults3 = [NSUserDefaults standardUserDefaults];
    [defaults3 setObject:saveString3 forKey:@"saveString3"];
    [defaults3 synchronize];

    NSString *saveString4 = Putts.text;
    NSUserDefaults *defaults4 = [NSUserDefaults standardUserDefaults];
    [defaults4 setObject:saveString4 forKey:@"saveString4"];
    [defaults4 synchronize];

    NSString *saveString5 = GIR.text;
    NSUserDefaults *defaults5 = [NSUserDefaults standardUserDefaults];
    [defaults5 setObject:saveString5 forKey:@"saveString5"];
    [defaults5 synchronize];

}

- (IBAction)Load:(id)sender
{
    NSUserDefaults *defaults = [NSUserDefaults standardUserDefaults];
    NSString *loadString = [defaults objectForKey:@"saveString"];
    [Date setText:loadString];
    [DateLabel setText:loadString];

    NSUserDefaults *defaults1 = [NSUserDefaults standardUserDefaults];
    NSString *loadString1 = [defaults1 objectForKey:@"saveString1"];
    [Course setText:loadString1];
    [CourseLabel setText:loadString1];

    NSUserDefaults *defaults2 = [NSUserDefaults standardUserDefaults];
    NSString *loadString2 = [defaults2 objectForKey:@"saveString2"];
    [Score setText:loadString2];

    NSUserDefaults *defaults3 = [NSUserDefaults standardUserDefaults];
    NSString *loadString3 = [defaults3 objectForKey:@"saveString3"];
    [Par setText:loadString3];

    NSUserDefaults *defaults4 = [NSUserDefaults standardUserDefaults];
    NSString *loadString4 = [defaults4 objectForKey:@"saveString4"];
    [Putts setText:loadString4];

    NSUserDefaults *defaults5 = [NSUserDefaults standardUserDefaults];
    NSString *loadString5 = [defaults5 objectForKey:@"saveString5"];
    [GIR setText:loadString5];
}

下一部分可能不那么重要我不知道，但我想我会粘贴所有内容，以便你了解我的程序做什么
