nsmutablearray – 从先前视图控制器中的数组获取数据,将其放入另一个TableViewController中

我有2个TableViewControllers.当@L_489_1@点击UIBarButtonItem时,它会在SaveViewController中保存来自UITextField,runnameField的文本.它应该采用runnameField的文本并将其放在一个数组,runsArray中.在RecordVC中,tableView的数据应来自runsArray.
有人可以帮我这个吗？我一直在谷歌搜索很长时间,找不到任何答案.

SaveViewController.h：

#import <UIKit/UIKit.h>
#import "RecordsViewController.h" //Next ViewController

@interface SaveViewController : UITableViewController <UITableViewDatasource,UITableViewDelegate> {
__weak IBOutlet UITextField *runnameField;
RecordsViewController *RecordsVCData;
}
@property (weak,nonatomiC) IBOutlet UITextField *runnameField;
@property (weak,nonatomiC) IBOutlet UITextView *runnotesTextView;
@property (weak,nonatomiC) IBOutlet UIBarButtonItem *saveBarItem;
@property (nonatomic,retain) RecordsViewController *RecordsVCData;

- (IBACtion)saverun:(UIBarButtonItem *)sender;
- (IBACtion)goAwayKeyboard:(id)sender;



@end

SaveViewController.m：

- (IBACtion)saverun:(UIBarButtonItem *)sender {
RecordsViewController *RecordsVC = [[RecordsViewController alloc] initWithNibName:nil bundle:nil];
RecordsVC.tableView = [[UITableView alloc] initWithFrame:CGRectZero style:UITableViewStyleGrouped];
self.RecordsVCData = RecordsVc;
[RecordsVC.runsArray addObject:[NSString StringWithFormat:@"%@",runnameField.text]];
[self presentModalViewController:recordsVC animated:YES];
}

- (IBACtion)goAwayKeyboard:(id)sender {
    [sender resignFirstResponder];
}

RecordsViewController.h：

#import <UIKit/UIKit.h>
@interface RecordsViewController : UITableViewController <UITableViewDatasource,UITableViewDelegate> {      
NSMutableArray *runsArray;
}
@property (weak,nonatomiC) NSString *runname;
@property (strong,nonatomiC) NSString *runnotes;
@property (weak,nonatomiC) UITableViewCell *cell;
@property (retain,nonatomiC) NSMutableArray *runsArray;
@end

RecordsViewController.m：

-(UITableViewCell *)tableView:(UITableView *)tableView cellForRowATindexPath:     (NSIndexPath *)indexPath {

// Identifier for retrieving reusable cells.
static NSString *cellIdentifier = @"MyCellIdentifier";

// Attempt to request the reusable cell.

UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:cellIdentifier];
cell = [[UITableViewCell alloc]initWithStyle:UITableViewCellStyleDefault     reusEIDentifier:cellIdentifier];
// No cell available - create one
if(cell == nil) {
    cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault
                                  reusEIDentifier:cellIdentifier];
[cell.textLabel setText:[NSString StringWithFormat:@"%@",[runsArray objectATindex:indexPath.row]]];

}

// Set the text of the cell to the runnameString.
[cell.textLabel setText:[NSString StringWithFormat:@"%@",[runsArray objectATindex:indexPath.row]]];
return cell;

}

- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section {
return [runsArray count];
}

任何帮助都很受欢迎.

谢谢,
