要在Navigation Bar上加入title的顯示
修改如下
1.在AppViewController.m加上顯示程式碼
- (void)viewDidLoad
{
[super viewDidLoad];
// Do any additional setup after loading the view, typically from a nib.
[self setTitle:@"Main Page"];
}
- (IBAction)toPage2:(id)sender {
SecondViewController *svc = [self.storyboard instantiateViewControllerWithIdentifier:@"SecondId"];
[svc setValue:@"Page2" forKey:@"transferString"];
[self.navigationController pushViewController:svc animated:YES];
}
2. 在SecondViewController.h加上傳送用的字串變數。
#import <UIKit/UIKit.h>
@interface SecondViewController : UIViewController
{
NSString *transferString;
}
@end
3. 在SecondViewController.m加上顯示title的程式碼
- (void)viewDidLoad
{
[super viewDidLoad];
// Do any additional setup after loading the view.
self.title=transferString;
}
4. 顯示結果
