Question

此代码中有内存泄漏。自从2周以来我一直在破坏它，我开始疯了。在此先感谢您的帮助：）

+(void) makeEvent:(int) event:(AppleEvent *)theEvent
{
    int sig = 'dock';
    OSErr err;
    AEAddressDesc targetDesc;

    targetDesc.descriptorType = typeNull;
    targetDesc.dataHandle = nil;

    err = AECreateDesc(
                   typeApplSignature,
                   &sig, sizeof(int),
                   &targetDesc
                   );
    if(err) { NSLog(@"Error creating descriptor: %i\n", err); }

    err = AECreateAppleEvent(
                         'DKoP', event,
                         &targetDesc,
                         kAutoGenerateReturnID, kAnyTransactionID,
                         theEvent
                         );
    if(err) { NSLog(@"Error creating event: %i\n", err); }

    AEDisposeDesc(&targetDesc);
    targetDesc.descriptorType = typeNull;
    targetDesc.dataHandle = nil;
}

addIntParm消息：

+(void) addIntParm:(int) parm: (int) keyword: (AppleEvent *)theEvent
{
    OSErr err = AEPutParamPtr(
                              theEvent, keyword,
                              typeSInt32, &parm, sizeof(parm)
                              );
    if(err) { NSLog(@"Error setting parameter: %i\n", err); }
}

addFloatParm消息：

+(void) addFloatParm:(float) parm: (int) keyword: (AppleEvent *)theEvent
{
    OSErr err = AEPutParamPtr(
                              theEvent, keyword,
                              typeIEEE32BitFloatingPoint, &parm, sizeof(parm)
                              );
    if(err) { NSLog(@"Error setting parameter: %i\n", err); }
}

sendEvent消息：

+(void) sendEvent:(AppleEvent *)theEvent
{
    OSErr err = AESend(
                       theEvent, nil, kAENoReply, //kAEWaitReply
                       kAENormalPriority, kNoTimeOut,
                       nil, nil
                       );
    if(err) { NSLog(@"Error sending: %i\n", err); }
}

Test消息：

+ (void) Test:(int)wid:(int)w:(int)h:(void*)points
{
    AppleEvent theEvent;
    [self makeEvent:'warp' :&theEvent];
    [self addIntParm:wid :'wnid' :&theEvent];
    [self addIntParm:w :'wwrp' :&theEvent];
    [self addIntParm:h :'hwrp' :&theEvent];
    [self addDataParm:points :sizeof(float)*4*h*w :'pots' :&theEvent];
    [self sendEvent:&theEvent];
    AEDisposeDesc(&theEvent);
}

~~我的猜测是你永远不会破坏AppleEvent *对象。 AECreateAppleEvent的文档说：~~

~~如果函数成功返回，则应用程序应该在完成使用后调用AEDisposeDesc函数来处理生成的Apple事件。~~

~~这个问题的一个线索是函数中有“Create”一词，（according to the Create Rule）表示你负责处理创建的内存。~~

（猜猜我应该在回答之前阅读所有发布的代码）

由于看起来你正在妥善处理这些东西，我会在你的代码上运行Leaks工具并确定实际泄漏的

。

另外，正如@DarkDust指出的那样，你应该真正阅读Cocoa Naming Conventions文档。

泄漏在哪里？
