CFUUIDBytes可能导致iOS内存泄漏(Potential iOS memory leak with CFUUIDBytes)

CFUUIDBytes可能导致iOS内存泄漏(Potential iOS memory leak with CFUUIDBytes)

我有一个静态方法定义如下：

+(NSString*)getNewIdAsBase64 { // Grab new uuid CFUUIDRef originalUuid = CFUUIDCreate(nil);//create a new UUID //NSLog(@"Step a: original uuidObj = %@",originalUuid); CFUUIDBytes originalBytes = CFUUIDGetUUIDBytes (originalUuid);//ISSUE NSData* data88 = [NSData dataWithBytes: &originalBytes length: sizeof(originalBytes)]; NSString* hugo = [data88 base64EncodedString]; return hugo; }

当我在我的项目上运行Product-> Analyze时，使用// ISSUE注释的行会引发以下问题：

Potential leak of an object alocated on line 23 and stored into 'originalUuid'

我做错了什么，我该如何解决？

谢谢

I have a static method defined as follows:

+(NSString*)getNewIdAsBase64 { // Grab new uuid CFUUIDRef originalUuid = CFUUIDCreate(nil);//create a new UUID //NSLog(@"Step a: original uuidObj = %@",originalUuid); CFUUIDBytes originalBytes = CFUUIDGetUUIDBytes (originalUuid);//ISSUE NSData* data88 = [NSData dataWithBytes: &originalBytes length: sizeof(originalBytes)]; NSString* hugo = [data88 base64EncodedString]; return hugo; }

When I run Product->Analyze on my project then the line commented with //ISSUE raises the following issue:

Potential leak of an object alocated on line 23 and stored into 'originalUuid'

What am I doing wrong, and how do I fix it?

Thanks

最满意答案

即使您使用ARC，也需要释放您创建的对象：

+(NSString*)getNewIdAsBase64 { // Grab new uuid CFUUIDRef originalUuid = CFUUIDCreate(nil);//create a new UUID //NSLog(@"Step a: original uuidObj = %@",originalUuid); CFUUIDBytes originalBytes = CFUUIDGetUUIDBytes (originalUuid);//ISSUE NSData* data88 = [NSData dataWithBytes: &originalBytes length: sizeof(originalBytes)]; NSString* hugo = [data88 base64EncodedString]; CFRelease(originalUuid); return hugo; }

You will need to release the object you create even if you are using ARC:

+(NSString*)getNewIdAsBase64 { // Grab new uuid CFUUIDRef originalUuid = CFUUIDCreate(nil);//create a new UUID //NSLog(@"Step a: original uuidObj = %@",originalUuid); CFUUIDBytes originalBytes = CFUUIDGetUUIDBytes (originalUuid);//ISSUE NSData* data88 = [NSData dataWithBytes: &originalBytes length: sizeof(originalBytes)]; NSString* hugo = [data88 base64EncodedString]; CFRelease(originalUuid); return hugo; }
