ios - 带有 EXC_BAD_ACCESS 的 NSArray obis 命令的最后一个元素出错(代码=EXC_ARM_DA_ALIGN

Question

我收到此错误 "EXC_BAD_ACCESS (code=EXC_ARM_DA_ALIGN"当 Xcode 到达最后一个“nil”语句以识别 NSArray* objs 的结尾时。

我看过其他评论类似的错误here和 here但那些似乎与我遇到的事情无关。我错过了什么很明显吗？有人遇到过这种情况么？

谢谢

                                NSArray *keys = [NSArray arrayWithObjects:ATHLETEID, CURRENTGRADE, EVENTNAME,
                                                 PERSONALREC, SEASONSBEST, EVENTMARK, MEETDATE, MEETID, MEETNAME,
                                                 EVENTPLACE, SEASON_NAME,
                                                 SORTMARK,TYPE, RESULTID, nil];

                                NSArray *objs = [NSArray arrayWithObjects:
                                                 athleteID,
                                                 t_currentGrade,
                                                 t_eventName,
                                                 t_eventPR,
                                                 t_eventSB,
                                                 t_markInEvent,
                                                 t_meetDate,
                                                 t_meetID,
                                                 t_meetName,
                                                 t_placeInEvent,
                                                 t_currentSeason,
                                                 t_sortMark,
                                                 t_typeOfEvent,
                                                 t_uniqueResultID,nil];

                                NSMutableDictionary *resultsFromSingleMeet [[NSMutableDictionary alloc]
                                                                              initWithObjects:objs
                                                                                      forKeys:keys];

这是我的 Debug Navigator 的转储:

我猜您正在向数组中添加基本类型(例如 NSUInteger 或 int)，而不是对象。确保将所有数字包装在 NSNumber 对象中。
