NSPropertyListSerialization 替代方案？
我可以使用任何代码来代替此代码片段吗？
NSString *anError = nil;
id plist;
plist = [NSPropertyListSerialization propertyListFromData:rawCourseArray mutabilityOption:NSPropertyListImmutable format:&format errorDescription:&anError];
if (anError != nil){
[anError release];
}
上面的代码导致内存泄漏，我无法纠正。我尝试释放错误，但没有成功。是否有另一种方法可以将数组序列化为 plist 格式而不会泄漏？
问候， BX
所以我编辑了代码，现在看起来像这样，但仍然存在泄漏。一定是其他什么东西。我在...之后添加了循环
NSError *error = nil;
id plist;
plist = [NSPropertyListSerialization propertyListWithData:rawCourseArray options:/*unused*/0
format:NULL error:&error];
//NSArray *entries = (NSArray *)d;
NSArray *entries = (NSArray *)plist;
//for (eachCourse in rawCourseArray)
for (NSDictionary *entry in entries)
{
//LOOP
}
Is there any code that I can use in place of this code snippet?
NSString *anError = nil;
id plist;
plist = [NSPropertyListSerialization propertyListFromData:rawCourseArray mutabilityOption:NSPropertyListImmutable format:&format errorDescription:&anError];
if (anError != nil){
[anError release];
}
The code above causes a memory leak which I can't correct. I try releasing the error but no luck. Is there another way to serialize an array into plist format without the leak?
Regards,

So I edited the code and it now looks like this but still a leak. It must be something esle. I included the loop after...
NSError *error = nil;
id plist;
plist = [NSPropertyListSerialization propertyListWithData:rawCourseArray options:/*unused*/0
format:NULL error:&error];
//NSArray *entries = (NSArray *)d;
NSArray *entries = (NSArray *)plist;
//for (eachCourse in rawCourseArray)
for (NSDictionary *entry in entries)
{
//LOOP
}

您使用的方法已过时，并且根据苹果文档即将被弃用，您应该使用
propertyListWithData:options:format:error:而不是联动
The method you are using is obsolete and is about to be deprecated according to the apple docs, you should use
propertyListWithData:options:format:error:insteadLinkage
该代码中没有内存泄漏。然而，存在潜在的崩溃。你不应该事实证明，-release错误对象，因为你不拥有它。NSPropertyListSerialization有一个糟糕的API。考虑使用+[NSPropertyListSerialization propertyListWithData:options:format:error:]变体。你确定这里有内存泄漏吗？重现泄漏所需的最少代码量是多少？
There is no memory leak in that code. However, there is a potential crash. You should notIt turns out that-releasethe error object, because you do not own it.NSPropertyListSerializationhas a terrible API. Consider using the+[NSPropertyListSerialization propertyListWithData:options:format:error:]variant instead.Are you sure there's a memory leak here? What's the minimal amount of code you need to reproduce the leak?
