使用gdb 调试QQV5.3.ipa时，发现堆栈信息与IDA分析的结果不对。

从$r1的选择子来看，应该是要与IDA分析结果保持一致。
问题2：
__text:01E0513C PUSH {R4-R7,LR}
__text:01E0513E ADD R7, SP, #0xC
__text:01E05140 PUSH.W {R8,R10}

__text:01E05148 MOV R0, #(selRef_getDiscussMemberListPathEnc_ - 0x1E05156)
__text:01E05150 MOV R8, R3

__text:01E05158 MOV R0, R4
__text:01E0515A BLX _objc_msgSend
__text:01E0515E MOV R6, R0
在 break *(0x01E0515E)断下时，po $r0 提示不是对象。
但根据IDA分析的结果应该是NString对象
请教大牛，是怎么回事哈，有办法解决吗
