調試當過我嘗試使用MR_importValuesForKeysWithObject我的應用程序崩潰來插入數據：的malloc：***錯誤對象：免費列表離隊無效的指針***設置malloc_error_break斷點在神奇紀錄IOS
malloc：對象錯誤0x174291c0e：無效指針從空閒列表中出列。
在malloc_error_break中設置斷點以進行調試。它崩潰
代碼是：
+ (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;
}

請給我一些暗示。
後崩潰日誌或完全回溯（設置了斷點後）。 – bbum
我已經更新崩潰堆棧框架 –
哦，喜悅。你在某處找到了一個記憶碎片。尋找緩衝區溢出等。不幸的是，malloc（）指出事情已經走出軌道的時間太晚了。 嘗試打開樂器中的Malloc調試。 – bbum
