libc++abi.dylib:以NSException类型的未捕获异常终止
提前感谢。您可以测试它。。尽量避免零。。而不是放一些东西。。。喜欢 [self displayAlertWithMessage:@“请输入有效用户名！”标题：@“Hello”和标签：1]
您需要发布警报视图，以便在函数中编写发布代码 根据崩溃日志，它告诉我，“[UIViewController\u loadViewFromNibNamed:bundle:”无法加载nib文件 但是，在我的项目中，我为UIViewController类创建了一个类别，并重写了
-（id）init[super init]而不是执行与视图控制器相关的其他操作
示例代码：
- (id)init
{
NSString *viewControllerName = [NSString stringWithFormat:@"%@",[self class]];
if([viewControllerName isEqualToString:@"UIAlertView"])
{
self = [super init];
}
else
{
// my stuff
}
return self;
}
你的代码是什么？你看过它在iOS7中实现方式的不同吗？用示例代码更新了问题，请检查..你的Xcode/iOS7安装完成了吗？异常表示无法加载NIB。@Wain，此应用程序是在xcode 4.5中开发的，并已转到应用程序商店。但是，由于这个原因，现在相同的构建正在崩溃。目前，为了调试此问题，我使用的是xcode 5 beta版和ios 7 beta版。可能是某种原因，因为警报试图以与当前视图不同的方向显示。看一看
