我已经更新了我的代码,
一切似乎都很好,但是当我按下添加按钮时,它并没有添加表格。
然后我意识到我忘了初始化数组,然后一切正常
#import "RootViewController.h"
#import "Hello_WorldAppDelegate.h"
@implementation RootViewController
@synthesize tableView;
- (void)viewDidLoad {
// Add the following line if you want the list to be editable
// self.navigationItem.leftBarButtonItem = self.editButtonItem;
}
- (IBAction)addToTable:(id)sender{
/*
UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"Do you want to say hello?" message:@"More info..." delegate:self cancelButtonTitle:@"Cancel" otherButtonTitles:@"Say Hello",nil];
[alert show];
[alert release];
*/
[myArray addObject:textField.text];
[self.tableView reloadData];
textField.text=@"";
/*
static NSString *MyIdentifier = @"MyIdentifier";
UITableViewCell *cell = [self.tableView dequeueReusableCellWithIdentifier:MyIdentifier];
if (cell == nil) {

[cell setText:[textField text]];
[self.tableView reloadData];

好的,我已经解决了我的问题
谢谢大家
