问题描述
我遇到了Appdelegate方法OpenURL的问题。
I am having an issue with the Appdelegate method OpenURL.
我已经设置了我的导入UTI和文档类型。但是，当我从邮件附件打开我的应用程序时，应用程序实施时会立即崩溃。
I have setup my Imported UTI's and Document Type. But when opening my app from a mail attachment, the app crashes immediately when I have the method implemented.
折旧的handleOpenURL有效，但不是OpenURL？
The depreciated handleOpenURL works, but not OpenURL?
目前我在实现中没有代码，我只是返回true。
At the moment I have no code in the implementation, and am just returning true.
func application(application: UIApplication, openURL url: NSURL, sourceApplication: String, annotation: AnyObject?) -> Bool {
return true
}
崩溃说线程1：EXC_BAD_ACCESS（代码-1，地址-0x0）
我真的不想使用弃用的方法。
I don't really want to have to use the deprecated method.
推荐答案
这是Swift编译器自动生成的方法签名与实际签名之间签名不匹配的典型特征。当您尝试将nil从Objective-C传递到Swift显式解包的可选项时，就会发生这种情况。更改注释参数以隐式展开，您应该是gtg。
This is fairly typical of a signature mismatch between the method signatures automatically generated by the Swift compiler and the actual signature. It happens when you try to pass nil from Objective-C into a Swift explicitly unwrapped optional. Change the annotation parameter to be implicitly unwrapped and you should be gtg.
