我正在设计的应用程序有问题。
基本上，用户按下一个按钮，将他们带到另一个屏幕，该屏幕可以选择拍照或选择退出的照片，然后通过电子邮件将其发送出去。
这是.h文件
#import <UIKit/UIKit.h>
@interface RoadSafetyViewController : UIViewController <UIImagePickerControllerDelegate, UINavigationControllerDelegate>
{
UIImagePickerController *picker1;
UIImagePickerController *picker2;
UIImage *image;
IBOutlet UIImageView *imageView;
}
-(IBAction)TakePhoto;
-(IBAction)ChooseExisting;
@end
和 .m 文件

@interface RoadSafetyViewController ()
@end
@implementation RoadSafetyViewController
- (IBAction)TakePhoto
{
picker1 = [[UIImagePickerController alloc] init];
picker1.delegate = self;
[picker1 setSourceType: UIImagePickerControllerSourceTypeCamera];
[self presentViewController:picker1 animated:YES completion:NULL];
[picker1 release];
}
- (IBAction)ChooseExisting
{
picker2 = [[UIImagePickerController alloc] init];
picker2.delegate = self;
[picker2 setSourceType: UIImagePickerControllerSourceTypePhotoLibrary];
[self presentViewController:picker2 animated:YES completion:NULL];
[picker2 release];
}
- (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info
{
image = [info objectForKey:UIImagePickerControllerOriginalImage];
[imageView setImage:image];
[self dismissViewControllerAnimated:YES completion:NULL];
}
- (void)imagePickerControllerDidCancel:(UIImagePickerController *)picker
{
[self dismissViewControllerAnimated:YES completion:NULL];
}
- (void)viewDidLoad
{
[super viewDidLoad];
// Do any additional setup after loading the view, typically from a nib.
}
- (void)didReceiveMemoryWarning
{
[super didReceiveMemoryWarning];
// Dispose of any resources that can be recreated.
}
@end
我在以下行收到 SIGBAT 错误
//
// main.m
// Road Safety App
//
// Created by Information Services on 30/09/13.
// Copyright (c) 2013 Shellharbour Sity Council. All rights reserved.
//
#import <UIKit/UIKit.h>
#import "RoadSafetyAppDelegate.h"
int main(int argc, char * argv[])
{
@autoreleasepool {
return UIApplicationMain(argc, argv, nil, NSStringFromClass([RoadSafetyAppDelegate class])); //here is where I'm getting a Thread 1: signal SIGBAT error.
}
}
这是错误的控制台输出。

我是 iOS 应用程序开发的新手，不知道这个错误来自哪里。任何识别和纠正错误的帮助都会很棒！
