UIImageJPEGRepresentation
原标题:UIImageJPEGRepresentation

我遇到麻烦,发现记忆泄露,这再次导致我的航程坠毁。 看来,分配给JPEGRepresentation的记忆并未公布。 由于UIImageJPEGRepresentation创建的NSData目标只有大约300千兆瓦(取决于图像),但在这个阶段,记忆的使用每张图像就猛增3-5兆字。

This is the code

QueuedObject* queuedObject = [[QueuedObject alloc] init];
[queuedObject setUrl:url];

QueuedObjectData* jsonQueuedData = [[QueuedObjectData alloc] init];
[jsonQueuedData setData:jsonData];
[jsonQueuedData setFilename:@"message.json"];
[jsonQueuedData setContentType:@"application/json"];
[jsonQueuedData setKeyValue:@"JSONMessage"];
[queuedObject addData:jsonQueuedData];

int i=1;

QueuedObjectData* imageData = [[QueuedObjectData alloc] init];

for(id file in files)
{
    if(file!=nil)
    {
        [imageData setData:UIImageJPEGRepresentation(file, 0.8)];
        [imageData setFilename:[NSString stringWithFormat:@"image%d.jpg",i]];
        [imageData setContentType:@"image/jpeg"];
        [imageData setKeyValue:@"image"];
        [queuedObject addData:imageData];
        i++;
    }
}

[[UploadQueue sharedInstance] addObject:queuedObject];


[jsonQueuedData release];
[jsonData release];
[url release];
[imageData release];
[queuedObject release];

也许你们有帮助我的想法

现在,在您的周期中,你只使用一个<代码>imageData的物体。 因此,你总是在不删除的情况下建立联合项目的代表。 颁布该法典:

for(id file in files)
{
    if(file!=nil)
    {
        QueuedObjectData* imageData = [[QueuedObjectData alloc] init];
        [imageData setData:UIImageJPEGRepresentation(file, 0.8)];
        [imageData setFilename:[NSString stringWithFormat:@"image%d.jpg",i]];
        [imageData setContentType:@"image/jpeg"];
        [imageData setKeyValue:@"image"];
        [queuedObject addData:imageData];
        [imageData release];
        i++;
    }
}

这里,你提出反对,使用,然后删除。
