如何在调试时检查保留计数
有谁知道如何在调试模式下检查对象的保留计数？我尝试添加表达式 [objInstance keepCount] 但它不起作用。我还在控制台中尝试了打印对象 PO [objInstance keepCount]，但它再次不起作用。
Does anybody know how can I check the retain count of an object while in debug mode? I have tried to add an expression [objInstance retainCount] but it did not work. I have also tried the print object PO [objInstance retainCount] in the console but again it did not work.

我猜你正在谈论在
GDB中获取retainCount？您可以使用
retainCount方法。这就是我进入代码的方式。
希望这就是您正在寻找的。
I am guessing you are talking about getting the
retainCountinGDB?You can use the
retainCountmethod.This is how I get in my Code.
Hope this is what you are looking for.
您可以使用以下命令打印此数字
。但是，由于
autorelease等原因，该数字并不可靠。您应该阅读内存管理 并确保您的retain和release调用匹配。您还可以运行“Build/Build”和“Analyze”来让 Xcode 帮助您找到可能的内存泄漏，但同样，这些只是潜在的泄漏。您需要亲自检查每一项才能确定。You can print this with
However, this number isn't reliable due to things like
autorelease. You should rather read up on memory management and make sure that yourretainandreleasecalls match up. You can also run Build/Build and Analyze to get Xcode to help you find possible memory leaks, but again, these are only potential leaks. You'll need to check each one yourself to be sure.
