Iphone UITextField（有时）在键入时使应用程序崩溃
我在UITextField上遇到了一个问题。当我在UITextField中键入时，它会使应用程序崩溃（有时，并非始终如此）。我怀疑这可能是内存问题，因为只有当我连续使用应用程序15分钟时才会发生这种情况。我希望我正确地进行了内存管理。应用程序崩溃，尤其是当我在文本字段中键入内容时，而不是在应用程序中执行其他操作时。我不确定是什么导致了这个问题 我在谷歌上搜索并找到了一些与UITextField相关的崩溃的讨论，但它们对我的问题没有帮助 这是我的事故记录Iphone UITextField（有时）在键入时使应用程序崩溃,iphone,objective-c,ios,uitextfield,Iphone,Objective C,Ios,Uitextfield,我在UITextField上遇到了一个问题。当我在UITextField中键入时，它会使应用程序崩溃（有时，并非始终如此）。我怀疑这可能是内存问题，因为只有当我连续使用应用程序15分钟时才会发生这种情况。我希望我正确地进行了内存管理。应用程序崩溃，尤其是当我在文本字段中键入内容时，而不是在应用程序中执行其他操作时。我不确定是什么导致了这个问题 我在谷歌上搜索并找到了一些与UITextField相关的崩溃的讨论，但它们对我的问题没有帮助 这是我的事故记录 0 libobjc.A.dylib
