我收到以下错误,但如何解决?
错误以绿色圆圈突出显示“引用计数对象在释放后被使用”

已编辑:我正在使用以下方法

+ (NSString *)GetUUID
{
CFUUIDRef theUUID = CFUUIDCreate(NULL);
CFStringRef string = CFUUIDCreateString(NULL, theUUID);
CFRelease(theUUID);
NSString *str = (__bridge NSString *)string;
CFRelease(string);
return str;
}


已编辑:通过使用 vijay 的以下简单代码解决

NSUUID  *UUID = [NSUUID UUID];
NSString* stringUUID = [UUID UUIDString];


enter image description here

最佳答案

我希望,您是因为 [DBManager GetUUID] 方法而收到此错误,您将在其中释放 CFRelease(cfUuid)

要获取 UUID,请尝试这个简化的 API

+ (NSString *)GetUUID
{

NSUUID *UUID = [NSUUID UUID];
NSString* stringUUID = [UUID UUIDString];

return stringUUID;

}
