ios - 如何诊断异常类型 : EXC_BAD_ACCESS (SIGSEGV) Exception Subtype: KERN_INVALID_ADDRESS?

Question

当我们通过 (diawi) IPA 链接安装时，按钮操作应用程序崩溃，但当我们通过设备中的 Xcode 按钮操作运行应用程序时，应用程序不会崩溃。

请查看崩溃日志

猜猜我为什么会收到此错误？有人知道如何解决这个问题吗？ 你能帮我解决这个问题吗？非常感谢。

Answer 1

当应用程序崩溃时我之前的代码是

int registerNumber = (int)nil;

Bool success = [[NSScanner scannerWithString:registerNumberInputTextField.text] scanInteger:&registerNumber];

之后，我将我的代码更改为

Bool success = [[NSScanner scannerWithString:registerNumberInputTextField.text] scanInt:&registerNumber];

因为我将 int 值指向 NSInteger，这导致我的应用程序崩溃，所以我如上所述更改了代码，现在它可以正常工作了。
