的malloc：***错误对象：免费列表离队无效的指针***设置malloc_error_break断点在神奇纪录IOS
问题描述：
调试当过我尝试使用MR_importValuesForKeysWithObject我的应用程序崩溃来插入数据：的malloc：***错误对象：免费列表离队无效的指针***设置malloc_error_break断点在神奇纪录IOS
malloc：对象错误0x174291c0e：无效指针从空闲列表中出列。
在malloc_error_break中设置断点以进行调试。它崩溃
代码是：
+ (NSArray *) MR_executeFetchRequest:(NSFetchRequest *)request inContext:(NSManagedObjectContext *)context
{
__block NSArray *results = nil;
[context performBlockAndWait:^{
NSError *error = nil;
results = [context executeFetchRequest:request error:&error];
if (results == nil)
{
[MagicalRecord handleErrors:error];
}
}];
return results;
}

请给我一些暗示。
答
如果得到响应数据对象的形式排列那么它的好，我们应该通过遍历一个对象使用
let defaultcontext = NSManagedObjectContext.MR_defaultContext()
Entityname.MR_importFromArray(listOfObjectData: [[NSObject : AnyObject]], inContext:defaultcontext)
defaultcontext.MR_saveToPersistentStoreAndWait()
而不是插入，然后将其保存在
后崩溃日志或完全回溯（设置了断点后）。 – bbum
我已经更新崩溃堆栈框架 –
哦，喜悦。你在某处找到了一个记忆碎片。寻找缓冲区溢出等。不幸的是，malloc（）指出事情已经走出轨道的时间太晚了。 尝试打开乐器中的Malloc调试。 – bbum
