如何在分配字符串值时解决内存泄漏

Question

I have have observed that there is a memory leak at this code. I have released the workingEntry at this class.

self.workingEntry.duration = [NSString stringWithFormat:@"%02d:%02d",[result minute], [result second]];

I inspect this using instruments in Xcode. How can i solve this kind of memory leak?

Answer 1

If you have Zombies turned on in Scheme:Diagnostics then memory will not be released and everything will look like a memory leak. Only test for memory leaks with Instruments if Zombies is turned off.

Answer 2

手动释放workEntry时，为什么不分配init并释放。

self.workingEntry.duration = [[NSString alloc]initWithFormat:@"%02d:%02d",[result minute], [result second]];
