切换到RootViewController

Question

我有2个不同的xcode项目。一个是主应用程序，它具有完整的设计准备等，并切换一些屏幕。然后我有一个位置应用程序，它会告诉你附近的医院等。我想要它做的是，如果我按主应用程序中的按钮，它会去的位置应用程序。所以我把这两个项目合而为一。终于它工作，但现在试图将位置应用程序链接到它的按钮时，它现在不会显示全屏。它只是向我展示了一张带医院，医生等的桌子，但我想看到位置应用程序的全屏。我认为这是rootviewcontroller。下面是代码：

.h文件中

#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; 

与.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 

我希望你能帮助我的人！

Answer 1

改变这种

-(IBAction)Over { 

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


} 

这个

-(IBAction)OverView { 

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


} 

并连接按钮动作“概述”反对过度

你可以简单地做这个改变你的根视图控制器。

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