問題描述
我只需要使用代碼手動查看同一故事板文件中的 UIView 控制器.我使用故事板來制作所有形式和連接.我的應用程序從導航控制器開始，它讓我可以訪問 UIView (LoginViewController)，然后它進入標簽欄控制器，它提供 4 個 UIViews.根據(jù)每個 UIView 我有 .h 和 .m 文件.我知道segue方法，它很簡單，但我需要手動方法.也許我做錯了什么.
All I need is to view a UIView controller in same storyboard file manually with code. I use storyboard to make all forms and connections. My application starts in navigation controller, which provides me access to UIView (LoginViewController) and then it goes to tab bar controller, which provides 4 UIViews. According to every UIView I have .h and .m files. I know about segue method, it is simple, but I need manual method. Maybe I am doing something wrong.
我試圖在 IBAction 中使用這種方法推送視圖控制器:
I was trying to use this method for pushing view controller in IBAction:
[self.view pushViewController:LoginViewController animated:YES];
但它會出錯:
意外的接口名稱LoginViewController":預期的表達式
Unexpected interface name ‘LoginViewController’: expected expression
我花了很長時間才弄清楚出了什么問題，但我沒有成功.這是我的 RollEnemyController.m 文件:
It took a lot of time to figure out what is wrong, but I had not succeed.
Here is my RollEnemyController.m file:
// RollEnemyController.m
#import "RollEnemyController.h"
#import "LoginViewController.h"
@implementation RollEnemyController;
@synthesize AttackButtonPressed;
- (IBAction)AttackButtonPressed:(id)sender {
LoginViewController* controller = [[LoginViewController alloc] initWithNibName:@"LoginViewController" bundle:nil];
[self.view pushViewController:controller];
}
@end
這是頭文件:
// RollEnemyController.h
#import <UIKit/UIKit.h>
@interface RollEnemyController : UIViewController
- (IBAction)RollButtonPressed:(id)sender;
@property (weak, nonatomic) IBOutlet UIButton *AttackButtonPressed;
@end
推薦答案
我猜你正在使用 UINavigationController.然后你可以簡單地這樣做:
I'm guessing that you are using a UINavigationController. Then you can simply do like this:
LoginViewController *controller = [[LoginViewController alloc] initWithNibName:@"LoginViewController" bundle:nil];
[self.navigationController pushViewController:controller animated:YES];
更新:
如果您使用的是 UIStoryboard，您可以設置新視圖控制器的標識符，然后將其推送到您的導航控制器上.要設置標識符，請選擇您的視圖，打開 Attributes Inspector，然后設置標識符(在我的示例中為LoginIdentifier").然后你可以這樣做:
If you are using a UIStoryboard, you can set the identifier of your new viewcontroller, and then push it onto your navigationController. To set the identifier, choose your view, open the Attributes Inspector, and set the identifier ("LoginIdentifier" in my example). Then you can do this:
LoginViewController *controller = [self.storyboard instantiateViewControllerWithIdentifier:@"LoginIdentifier"];
[self.navigationController pushViewController:controller animated:YES];
作為旁注，我看到您在方法中使用了大寫字符.您可能應該盡量避免這種情況，而是在方法名稱中使用降低的首字符.既然你說你正在學習 Objective-C，你應該在這里查看這個很棒的線程:鏈接.
As a sidenote, I see that you are using capital characters for your methods. You should probably try to avoid that, and instead use lowered first-characters in your method names. And since you say you are learning Objective-C, you should check out this awesome thread here on SO: link.
更新 2:
這里是一個 zip 文件，其中包含一個項目，展示了如何執(zhí)行此操作.:-)
Here is a zip file with a project showing how to do this. :-)
