我有 2 个 TableViewController。当用户点击 UIBarButtonItem 时,它将来自 UITextField、runnameField 的文本保存在 SaveViewController 中。它应该获取runnameField 的文本并将其放入一个数组runsArray 中。在 RecordVC 中,tableView 的数据应该来自于 runsArray。有人可以帮我吗?我已经在谷歌上搜索了很长时间,但找不到任何答案。
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
保存视图控制器.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];
}
任何帮助都将不胜感激。
谢谢,
