我正在制作一个简单的数学加法应用程序，Xcode表示它构建正确，但应用程序不会在模拟器或我的设备上打开。这是一个基于winow的应用程序，但我手动添加UITabBarController。
这是我的AreaViewController.h所说的
#import <UIKit/UIKit.h>
@interface AreaViewController : UIViewController {
<snipped ivars>
}
@property (retain, nonatomic) UITextField *add11;
@property (retain, nonatomic) UITextField *add12;
@property (retain, nonatomic) UITextField *add13;
@property (retain, nonatomic) UITextField *add21;
@property (retain, nonatomic) UITextField *add22;
@property (retain, nonatomic) UITextField *add23;
@property (retain, nonatomic) UITextField *add31;
@property (retain, nonatomic) UITextField *add32;
@property (retain, nonatomic) UITextField *add33;
@property (retain, nonatomic) UILabel *add1Result;
@property (retain, nonatomic) UILabel *add2Result;
@property (retain, nonatomic) UILabel *add3Result;
-(IBAction)calculate:(id)sender;
-(IBAction)hideKeyboard:(id)sender;
@end
我的AreaViewController.m
#import "AreaViewController.h"
@implementation AreaViewController
@synthesize add11, add12, add13;
@synthesize add21, add22, add23;
@synthesize add31, add32, add33;
@synthesize add1Result, add2Result, add3Result;
-(IBAction)calculate:(id)sender {
float floatAdd1Result=[add11.text floatValue]+[add12.text floatValue]+[add13.text floatValue];
float floatAdd2Result=[add21.text floatValue]+[add22.text floatValue]+[add23.text floatValue];
float floatAdd3Result=[add31.text floatValue]+[add32.text floatValue]+[add33.text floatValue];
add1Result.text=[NSString stringWithFormat:@"%1.2f",floatAdd1Result];
add2Result.text=[NSString stringWithFormat:@"%1.2f",floatAdd2Result];
add3Result.text=[NSString stringWithFormat:@"%1.2f",floatAdd3Result];
}
-(IBAction)hideKeyboard:(id)sender {
[add11 resignFirstResponder];
[add12 resignFirstResponder];
[add13 resignFirstResponder];
[add21 resignFirstResponder];
[add22 resignFirstResponder];
[add23 resignFirstResponder];
[add31 resignFirstResponder];
[add32 resignFirstResponder];
[add33 resignFirstResponder];
}
- (void)dealloc {
[add11 release];
[add12 release];
[add13 release];
[add21 release];
[add22 release];
[add23 release];
[add31 release];
[add32 release];
[add33 release];
[add1Result release];
[add2Result release];
[add2Result release];
[super dealloc];
}
@end

我尽可能地减少了代码。我已经删除了实例变量声明并留下了@property语句，折叠了@synthesize行，简化了代码，删除了死方法，剪掉了很长的重复内容等等。我还删除了代码下载链接，因为它仅链接到.xcodeproj文件的压缩副本（但没有源）。

你在动态加载器中死亡的事实似乎暗示你的二进制文件没有正确构建。当我开始遇到奇怪的错误时，我发现最好清理整个项目并从头开始重新构建所有内容。要清理，只需转到Build菜单并选择“Clean All Targets”。完成后，尝试再次构建和运行。

有时这对我有帮助：
在做＃5之前，先备份你的项目......以防万一。
编辑：
您的磁盘或Xcode可能有问题。使用磁盘工具并验证/修复磁盘上的权限，删除然后从新版本重新安装Xcode / SDk。看看是否有效。
