线程1信号SIGBART

-1

我对此做了一些研究，但唉，没有答案。我制作了一个使用ASCII码的代码机器。没有错误或警告。但是当我运行它时，我得到这个错误：线程1：信号SIGBART。我认为它与UITextView“编码”有关，但我不确定。编辑：当我点击“编码”按钮（（IBAction）StartEncodeDecode）发生崩溃。线程1信号SIGBART

全部输出记录如下。不能相信我是这样一个新手：

2013-08-28 14:00:57.086 Code Machine[2285:11303] -[CMViewController decodeEncode:]: unrecognized selector sent to instance 0x7151190 2013-08-28 14:00:57.155 Code Machine[2285:11303] * Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '-[CMViewController decodeEncode:]: unrecognized selector sent to instance 0x7151190' * First throw call stack: (0x1c94012 0x10d1e7e 0x1d1f4bd 0x1c83bbc 0x1c8394e 0x10e5705 0x192c0 0x19258 0xda021 0xda57f 0xd96e8 0x48cef 0x48f02 0x26d4a 0x18698 0x1befdf9 0x1befad0 0x1c09bf5 0x1c09962 0x1c3abb6 0x1c39f44 0x1c39e1b 0x1bee7e3 0x1bee668 0x15ffc 0x1ded 0x1d15) libc++abi.dylib: terminate called throwing an exception (lldb)

结束编辑。

代码如下：

查看Controller.m或者：

#import "CMViewController.h" 
#import "CMAEncode.h" 

@interface CMViewController() 
@property (weak, nonatomic) IBOutlet UITextView *toCode; 
@property (weak, nonatomic) IBOutlet UITextView *coded; //I think the problem is with this text view. 
@property (weak, nonatomic) IBOutlet UISwitch *onOrOff; 

- (IBAction)StartEncodeDecode:(id)sender; 




@end 


@implementation CMViewController 


- (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. 
} 
- (BOOL)textView:(UITextView *)textView shouldChangeTextInRange:(NSRange)range 
replacementText:(NSString *)text 
{ 

    if ([text isEqualToString:@"\n"]) { 

     [textView resignFirstResponder]; 
     // Return FALSE so that the final '\n' character doesn't get added 
     return NO; 
    } 
    // For any other character return TRUE so that the text gets added to the view 
    return YES; 
} 
- (IBAction)StartEncodeDecode:(id)sender { 

    NSString *finishedText; 
    NSString *toCode = self.toCode.text; 
    if (self.onOrOff.on == FALSE) { 
     finishedText = [CMAEncode encodeText:toCode]; 
     self.coded.text = finishedText; 
    } else { 
    } 
} 

@end

CMAEncode.m

#import "CMAEncode.h" 

@implementation CMAEncode : NSObject 

+ (NSString *) encodeText:(NSString *)text { 

    NSString *ToEncode = text; 
    NSMutableString *Encoded = [NSMutableString string]; 
    int letter; 
    NSUInteger i = 0; 

    while (i < ([ToEncode length] - 1)) { 
     letter = [ToEncode characterAtIndex:i]; 
     NSString *toAppend = [NSString stringWithFormat:@"%d|", letter]; 
     [Encoded appendString:toAppend]; 
     i = i + 1; 
    } 

    return Encoded; 




} 

@end

这里就是错误实际发生的类。这是电话main.m：

#import <UIKit/UIKit.h> 

#import "CMAppDelegate.h" 

int main(int argc, char *argv[]) 
{ 
    @autoreleasepool { 
     return UIApplicationMain(argc, argv, nil, NSStringFromClass([CMAppDelegate class])); //This is where the error occurred. 
    } 
}

感谢您的帮助！

什么是链接到'StartEncodeDecode：''IBAction'？它是一个按钮或其他东西？ – Amar

这是一个按钮。 – DonyorM

只需断开所有连接并再次连接。 – Rajneesh071

如果您执行的操作IBAction与名称“decodeEncode”链接，检入IB ui元素。可能是因为你已经将它链接到IB（快速的方法是右键点击IB &上的viewcontroller它将显示所有内容）。看起来你有一些操作正在执行名为“decodeEncode”但该方法不存在于你的CMViewController类。在旁注意如果你确实有这个方法实现，你可以说明它的位置？把这种方法在你的CMViewController.m文件&检查日志

- (void)decodeEncode:(NSObject *)sender 
{ 

NSLog(@"sending object >> %@", sender); 

}
