切换到RootViewController

Question

我有两个不同的xcode项目。一个是主要的应用程序，它已准备好完整的设计等，并切换一些屏幕。然后我有一个位置应用程序，向您显示附近的医院等。我想要它做的是，如果我按下主应用程序中的按钮，它会转到位置应用程序。所以我把这两个项目合二为一。最后它工作，但现在当尝试将位置应用程序链接到它工作的按钮，但它没有显示全屏。它只是向我展示了医院，医生等的表格，但我希望看到位置应用程序的全屏。我认为这是rootviewcontroller。这是代码：

.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;

.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

我希望你能帮助我们！

Answer 1

您只需执行此操作即可更改根视图控制器。

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

Answer 2

更改此

-(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
