问题描述
我正在做一个非常简单的 NSArray 搜索，如下
I am doing a very simple NSArray search as follows
BOOL isCashTender = [_tenderRows containsObject: @"Cash"];
数组的调试输出告诉我现金"中有一个对象，如下所示(倒数第二个)
A debug output of the array tells me there is an object in there "Cash" as seen below (its the second to last one)
2017-04-07 11:20:27.644551 NWMobileTill[2134:701297] tenderRowsarray:(
"<Tender: 0x17009c2a0> (entity: Tender; id: 0xd0000000002c0004 <x-coredata://BE2CD993-FDED-43CE-99A3-88597A0E8046/Tender/p11> ; data: {\n amount = 10;\n authCode = nil;\n brandId = XX;\n cardEntryMode = nil;\n cardType = nil;\n createdDate = \"2017-04-07T11:20:22+08:00\";\n createdDateUtc = \"2017-04-07T03:20:22\";\n currency = EUR;\n extRefNo = \"Cash-In-EUR\";\n hashedPan = nil;\n inOrOut = IN;\n isSynched = 0;\n obfPan = nil;\n orderNumber = \"1-20170407112015\";\n status = 95;\n synchDate = nil;\n synchDateUtc = nil;\n tillId = 1;\n type = Cash;\n userName = a;\n})"
)
但是当我查看 BOOL 的调试输出时，它返回 0，而我预期它是 1，这是为什么呢?
But when I look at the debug output of my BOOL it returns 0 when I expected it to be 1, why is that?

推荐答案
tenderRows 只包含一个对象，而不是字符串 "Cash";这是一个 Tender 实体.
tenderRows contains just one object, and it isn't a string "Cash"; it's a Tender entity.
该 Tender 实体可能有一个 type 属性，其值为 "Cash"，但这不是您问的问题(使用 containsObject:).
That Tender entity may have a type attribute whose value is "Cash", but that is not the question you asked (with containsObject:).
