当我尝试向NSMutableArray插入一个对象时,我收到一个'Program received signal:SIGABRT'错误,但是我不明白为什么.
这是我的代码,特别insertObject:value是导致错误的代码.
NSMutableDictionary *myDictionary = [NSMutableDictionary dictionary];
[myDictionary setValue:valueName.text forKey:kValueName];
[myDictionary setObject:subValuesList forKey:kSubValuesList];
MyAppDelegate *appDelegate = [[UIApplication sharedApplication] delegate];
int position = appDelegate.position;
NSMutableArray *valuesList = [[NSUserDefaults standardUserDefaults] objectForKey:kValuesArray];
[valuesList insertObject:myDictionary atIndex:position];
我正在开发一个iOS应用程序(http://affogato.visioa.com/),它实现了一个标签栏控制器,导航控制器和一个tableview控制器,每当我运行我的应用程序时,我得到:"线程1:程序接收信号: "SIGABRT".任何人都可以解释为什么我会得到这个以及如何纠正它？
以下是控制台:

myViewController *newView = [[myViewController alloc] initWithNibName:@"myViewController"
bundle:nil];
[[self navigationController] pushViewController:newView animated:YES];
转换到下一个视图.我有一个这样的视图控制器但是只会在iOS 5上导致此行崩溃.它在iOS 6上工作得非常好.我很困惑.崩溃没有真正的细节.这是一个强调main.m行的SIGABRT:
exitStatus = UIApplicationMain( argc, argv, nil, NSStringFromClass([ApplicationDelegate class]));

我是Xcode的新手.我正在使用Xcode 5.1.1.在OS X 10.9.2下.我想做一个非常简单的Mac应用程序,以了解如何在启动时在WebView中加载URL.在阅读了几个来源(包括来自StackOverflow的问题)之后,我尝试了大约10种不同的方法并完成了相同的结果 - 在Build&Run之后,屏幕上没有窗口.错误消息是:
在控制台区域:*由于未捕获的异常'NSInvalidUnarchiveOperationException'终止应用程序,原因:'* - [NSKeyedUnarchiver decodeObjectForKey:]:无法解码类的对象(WebView)'
libc ++ abi.dylib:以NSException类型的未捕获异常终止
我做了什么:
在IB中,我创建了WebView窗口并创建了一个插座zzz(我试图从AppDelegate按住Ctrl键拖动到WebView,反之亦然).所以这是我完成的代码:
// AppDelegate.h
#import <Cocoa/Cocoa.h>
#import <WebKit/WebKit.h>
@interface AppDelegate : NSObject <NSApplicationDelegate>
@property (assign) IBOutlet NSWindow *window;
@property (retain, nonatomic) IBOutlet WebView *zzz;
@end
// AppDelegate.m
#import "AppDelegate.h"
@implementation AppDelegate
- (void)applicationDidFinishLaunching:(NSNotification *)aNotification
{
[self.zzz setMainFrameURL:@"http://www.google.com/"];
// I tried to put this code into awakeFromNib procedure too
}
@end
我尝试使用applicationDidFinishLaunching/awakeFromNib中的代码,如下所示:
NSString *urlAddress = @"http://www.google.com/";
NSURL *url = [NSURL URLWithString:urlAddress];
NSURLRequest *requestObj = [NSURLRequest …我尝试编写游戏代码(我在Swift中使用本教程https://www.youtube.com/watch?v=LkYpoRj-7hA im new).那是我的代码到目前为止:

//Buttons

@IBOutlet var ticTacBtn_A02: UIButton = nil

所以我有一个openfoam求解器,它使用(包括)大量代码,我很难找到错误.我编译

并且在使用适当的选项运行求解器之后,它在我的return语句之后(或同时)崩溃:

修复所有代码问题后,我现在有一个无错误的项目,但是当我点击我的前屏幕上的一个特定按钮时,它会抛出SIGABRT错误.
我确信它与目标页面上的UIPickerView元素有关,因为我已经删除,检查并重新添加了所有的segue和outlet以确保从那一方清楚一切.
控制台显示以下内容:
2016-08-02 18:59:46.607 ForceIt![38735:2895259] - [ForceIt_.DirectoryViewController numberOfComponentsInPickerView:]:无法识别的选择器发送到实例0x7fcd68c0c210 2016-08-02 18:59:46.618 ForceIt![38735:2895259]***由于未捕获的异常'NSInvalidArgumentException'终止应用程序,原因:' - [ForceIt_.DirectoryViewController numberOfComponentsInPickerView:]:无法识别的选择器发送到实例0x7fcd68c0c210'

但是，我找不到故事板或 .swift 文件中缺少的连接。构建时没有错误消息，似乎由于某种原因程序找不到 IBOutlet，我不明白为什么考虑到我已将它们全部删除并在 swift 文件和情节提要连接器中多次重新连接而没有改变。
感谢您提供任何帮助。如果需要，将提供进一步的屏幕截图。
typedef struct{
void *val;
}struct_t;
void test(int val)
{
struct_t *s = malloc(sizeof(struct_t));
s->val = malloc(sizeof(int));
*(int*)&s->val = val;
free(s->val);
}
free会产生一个sigabrt,但我认为这更像是我正在施放s-> val以使分配工作的方式的症状.执行此任务的正确方法是什么？
我在我的C程序中收到一个奇怪的SIGABRT,这是我出现问题的函数:
int get_interface_mac_addr(Interface* iface) {
char arquivo[10];
sprintf(arquivo, "/sys/class/net/%s/address", iface->interface_name);
int fd;
fd = open(arquivo, O_RDONLY, 0);
char buf[100];
read(fd, buf, sizeof (buf));
buf[strlen(buf) - 1] = '\0';
strcpy(iface->interface_mac_addr, buf);
close(fd);
return GET_MAC_ADDR_SUCCESS;
}
错误发生在最后一行代码"}".
我尝试使用GDB进行调试,但我是新手,所以我不理解GDB告诉我的很多事情.以下是GDB的输出:
