问题描述
我写下面的代码:
JSImgDeleteCollectionViewCell *cell = [collectionView dequeueReusableCellWithReuseIdentifier:displayCellID forIndexPath:indexPath];
在使用它之前,我已注册它:
and before use it,I registered it:
[_displayImgCollectionView registerNib:[UINib nibWithNibName:displayCellID bundle:nil] forCellWithReuseIdentifier:displayCellID];
在xcode7.3中可以,但是当我在xcode8.1中运行此命令时,出现了某些错误,味精是这样的:
it is allright in xcode7.3,but when I run this in xcode8.1,there is sth wrong,the msg like this:
提供给CFRunLoopRunSpecific的无效模式'kCFRunLoopCommonModes'-在_CFRunLoopError_RunCalledWithInvalidMode上中断以进行调试.每次执行该消息只会出现一次.
invalid mode 'kCFRunLoopCommonModes' provided to CFRunLoopRunSpecific - break on _CFRunLoopError_RunCalledWithInvalidMode to debug. This message will only appear once per execution.

推荐答案
我也遇到过同样的问题
CFRunLoopRunSpecific-在_CFRunLoopError_RunCalledWithInvalidMode上中断以进行调试.每次执行该消息只会出现一次.
CFRunLoopRunSpecific - break on _CFRunLoopError_RunCalledWithInvalidMode to debug. This message will only appear once per execution.
但是我发现这不是崩溃应用程序的真正原因,我在上述消息下方找到的真正原因是由于未捕获的异常"NSInvalidArgumentException"而终止应用程序,原因:-[NSNull长度]:无法识别选择器发送到控制台上的实例0x102ed2fb0'是真正的原因.因此,我处理了从后端收到的空值.
But I found this is not the real reason behind crashing the app, the real reason i found below the above message as Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '-[NSNull length]:unrecognized selector sent to instance 0x102ed2fb0' on console is real reason.So, I handle the null value which i received from backend.
这篇关于提供给CFRunLoopRunSpecific的xcode8.1:无效模式'kCFRunLoopCommonModes'-在_CFRunLoopError_RunCalledWithInvalidMode上中断以进行调试的文章就介绍到这了,希望我们推荐的答案对大家有所帮助,也希望大家多多支持!
