切换到RootViewController

Question

我有两个不同的xcode项目。一个是主应用程序，它已经准备好了完整的设计，并切换了一些屏幕。然后我有一个定位应用程序，它可以向你显示附近的医院等。我想要它做的是，如果我在主应用程序中按下一个按钮，它就会进入定位应用程序。因此，我将这两个项目合并为一个。最后，它起作用了，但现在，当尝试将定位应用程序链接到按钮时，它起作用了，但它不能全屏显示。它只给我显示了一张有医院、医生等的桌子，但我想要看到定位应用程序的全屏幕。我还以为是rootviewcontroller呢。代码如下：

.h文件

#import <UIKit/UIKit.h>
#import "VacaturesViewController.h"
#import "Over.h"
#import "RootViewController.h"
#import <CoreData/CoreData.h>
#import "NewKeywordViewController.h"

@interface Home : UIViewController {

//UI Button instance variable
UIButton *tweetButton;



}

// Properties
@property (nonatomic, strong) IBOutlet UIButton *tweetButton;




// Methods
-(IBAction)sendTweet:(id)sender;
-(IBAction)vacatures;
-(IBAction)zoeken;
-(IBAction)Over;

和.m文件：

#import "Home.h"
#import "RootViewController.h"
#import "Reachability.h"
#import "AppDelegate.h"
#import "MapViewController.h"
#import "InfoViewController.h"
#import "Keyword.h"





@interface Home ()

@end

@implementation Home

@synthesize tweetButton;




-(IBAction)vacatures {

    VacaturesViewController *screen = [[VacaturesViewController alloc] initWithNibName:nil       bundle:nil];
screen.modalTransitionStyle = UIModalTransitionStyleCrossDissolve;
[self presentModalViewController:screen animated:YES];


}

-(IBAction)zoeken {

RootViewController *screen = [[[RootViewController alloc] initWithNibName:nil bundle:nil]   autorelease];
[self presentModalViewController:screen animated:YES];

}

-(IBAction)Over {

Over *screen = [[Over alloc] initWithNibName:nil bundle:nil];
screen.modalTransitionStyle = UIModalTransitionStyleCrossDissolve;
[self presentModalViewController:screen animated:YES];


}





-(IBAction)sendTweet:(id)sender
{
NSString *tweet = [[NSString alloc] initWithString:@"Door de Thuiszorg applicatie heb ik   altijd de juiste zorg in de buurt! Downloaden dus!"]; // Creates the string that is used for the tweet.
{
    TWTweetComposeViewController *tweeter = [[TWTweetComposeViewController alloc] init];    // Allocates and initialises the Tweet "view".
    [tweeter setInitialText:tweet]; // Sets the text of the tweet to be that of the   NSString *tweet
    [self presentModalViewController:tweeter animated:YES]; //Present the Tweet view to   the user.
}
}

- (void)viewDidLoad
{
[super viewDidLoad];



    // Do any additional setup after loading the view, typically from a nib.
}

- (void)viewDidUnload
{
[super viewDidUnload];
// Release any retained subviews of the main view.
}

- (BOOL)shouldAutorotateToInterfaceOrientation:  (UIInterfaceOrientation)interfaceOrientation
{
return (interfaceOrientation != UIInterfaceOrientationPortraitUpsideDown);
}



@end

我希望你们能帮助我，伙计们！

Answer 1

您可以简单地通过执行此操作来更改根视图控制器。

 Over *screen = [[Over alloc] initWithNibName:@"Over" bundle:nil];
[[AppDelegate application].window.rootViewController = over;

Answer 2

改变这一点

-(IBAction)Over {

Over *screen = [[Over alloc] initWithNibName:nil bundle:nil];
screen.modalTransitionStyle = UIModalTransitionStyleCrossDissolve;
[self presentModalViewController:screen animated:YES];


}

到这个

-(IBAction)OverView {

Over *screen = [[Over alloc] initWithNibName:nil bundle:nil];
screen.modalTransitionStyle = UIModalTransitionStyleCrossDissolve;
[self presentModalViewController:screen animated:YES];


}

并将按钮操作连接到与Over相反的"OverView“
