所以我得到这个奇怪的sigabrt异常，我添加了一个所有异常断点，我得到异常的行是这样的：
[self performSegueWithIdentifier: @"SolveSound" sender: self];
我无法理解为什么会抛出异常，我建立了一个连接（segue）到下一个视图并将其命名为SolveSound。
如果需要更多代码，请告诉我。

顺便说一下，这就是我在输出中得到的结果。
编辑：添加了SoundViewController代码：
@interface SoundViewController ()
@end
@implementation SoundViewController
{
SoundItem *currentSound;
}
- (void)viewDidLoad
{
[super viewDidLoad];
// Do any additional setup after loading the view.
}
- (void)viewWillAppear:(BOOL)animated
{
[super viewWillAppear:animated];
[self.answerTextField becomeFirstResponder];
}
- (BOOL)textField:(UITextField *)theTextField shouldChangeCharactersInRange:(NSRange)range replacementString:(NSString *)string
{
NSString *newText = [theTextField.text stringByReplacingCharactersInRange:range withString:string];
if ([newText length] > 0) {
self.checkButton.enabled = YES;
} else {
self.checkButton.enabled = NO;
}
return YES;
}
- (void)didReceiveMemoryWarning
{
[super didReceiveMemoryWarning];
// Dispose of any resources that can be recreated.
}
@end
编辑：添加了堆栈跟踪
