それぞれに4〜5個のView Controllerがあり、実装が不完全であることを示しています。1つのViewControllerを以下に示します

#import <UIKit/UIKit.h>
#import <QuartzCore/QuartzCore.h>
#import "CereniaAppDelegate.h"

@interface MainViewController : UIViewController  <UITextFieldDelegate, UITableViewDelegate, UITableViewDataSource>{
    IBOutlet UIButton*homeButton;
    IBOutlet UIButton*economicDataButton;
    IBOutlet UIButton*riskButton;
    IBOutlet UIButton*financialImpactButton;
    IBOutlet UIButton*probabilitiesButton;
    IBOutlet UIButton*enterButton;
}



-(IBAction)enterButtonAction;
-(IBAction)homeButtonAction;
-(IBAction)economicDataButtonAction;
-(IBAction)riskButtonAction;
-(IBAction)financialImpactButtonAction;
-(IBAction)probabilitiesButtonAction;

@end

実装

#import "MainViewController.h"
#import "EconomicDataViewController.h"
#import "ProbabilitiesViewController.h"
#import "RiskViewController.h"
#import "FinancialImpactViewController.h"

@implementation MainViewController

-(IBAction)homeButtonAction{

}

-(IBAction)enterButtonAction{   
    EconomicDataViewController*targetContrlloer=[[EconomicDataViewController alloc] init];
    [self.navigationController pushViewController:targetContrlloer animated:YES];
}


-(IBAction)economicDataButtonAction{
    EconomicDataViewController*targetContrlloer=[[EconomicDataViewController alloc] init];
    [self.navigationController pushViewController:targetContrlloer animated:YES];
}



-(IBAction)riskButtonAction{
    RiskViewController*targetContrlloer=[[RiskViewController alloc] init];
    [self.navigationController pushViewController:targetContrlloer animated:YES];
}

-(IBAction)financialImpactButtonAction{
    FinancialImpactViewController*targetContrlloer=[[FinancialImpactViewController alloc] init];
    [self.navigationController pushViewController:targetContrlloer animated:YES];
}

-(IBAction)probabilitiesButtonAction{
    ProbabilitiesViewController*targetContrlloer=[[ProbabilitiesViewController alloc] init];
    [self.navigationController pushViewController:targetContrlloer animated:YES];
}

これは、UITextFieldDelegate、UITableViewDelegate、UITableViewDataSource のデリゲート メソッドを実装していないためです。それを行うと、エラーが消えるはずです。

持っているすべての UIButtons のプロパティを作成し、.m ファイルで @synthesize します。

お気に入り：

MainViewController.h

@interface MainViewController : UIViewController  <UITextFieldDelegate, UITableViewDelegate, UITableViewDataSource>{
    UIButton*homeButton;

}

@property(nonatomic,retain) IBOutlet UIButton *homeButton;



MainViewController.m

@synthesize homeButton;
