修复ARC中潜在的内存泄漏 [英] Fix potential memory leak in ARC

问题描述

以下单例类（SharedManager）辅助方法可能导致保留周期。在静态分析器中收到警告：在线路上分配的对象的潜在泄漏......我该如何解决？

The following singleton class (SharedManager) helper method might be causing a retain cycle. Getting warnings in static analyzer: "Potential leak of an object allocated at line ..." How can I fix?

我确实试过制作ivar uuid __weak但是当我分析时仍会出现警告。

I did try making ivar uuid __weak but warning still appears when I analyze.

    NSString  *__weak uuid =  (__bridge NSString *)CFUUIDCreateString(kCFAllocatorDefault, uuidObject);

谢谢

在课堂上被叫像这样：

myUUID = [SharedManager generateUUID];



+ (NSString *)generateUUID
{

 CFUUIDRef uuidObject = CFUUIDCreate(kCFAllocatorDefault);
 NSString  *uuid =  (__bridge NSString *)CFUUIDCreateString(kCFAllocatorDefault, uuidObject);
CFRelease(uuidObject);

  return uuid;

}

推荐答案

NSString  *uuid =  (__bridge_transfer NSString *)CFUUIDCreateString(kCFAllocatorDefault, uuidObject);

这会删除警告吗？
