objective-c – 对方法的参数调用太多

(lldb) po [NSString stringWithFormat:@"tel:%@",item.CNUMBER]
error: too many arguments to method call,expected 1,have 2

我看过的一些问题但对我没有帮助.

Too many arguments to method call expected 1,have 2

Too many arguments to method call

Too many arguments to method call,have 2?(Xcode)

我甚至有一个时刻,我质疑我的理智,并去了苹果文件. https://developer.apple.com/library/content/documentation/Cocoa/Conceptual/Strings/Articles/FormatStrings.html

[NSString stringWithFormat:@"Long %C dash",0x2014]; // from apples doc

结果是一样的……

(lldb) po [NSString stringWithFormat:@"Long %C dash",0x2014];
error: too many arguments to method call,have 2

即时通讯使用macOS 10.12.4和xCode 8.3.2.我甚至从头开始重新安装xCode.什么可能导致这个想法！？

e：使用po item.CNUMBER给我的电话号码就像它应该的那样

item只是我用来解析json响应的模型,没有涉及的方法.

LeasesModel *item; // declared as an instance var

…

@interface LeasesModel : NSObject
@property(nonatomic,strong) NSString *ID,*PROPERTYNAME,*ADDRESS1,*ADDRESS2,*CITY,*STATE,*ZIP,*WBPOINT,*COMMENTS,*CNAME,*CNUMBER,*CEMAIL,*CCOMPANY,*ISRETAILSPACE,*ISOFFICESPACE,*ISCOMMUNITYFACILITY,*SQFT,*STATUS,*ASKINGRENT,*FLOORCOUNT,*FLOOR1SF,*FLOOR1ASKING,*FLOOR2SF,*FLOOR2ASKING,*FLOOR3SF,*FLOOR3ASKING,*FLOOR4SF,*FLOOR4ASKING,*FLOOR5SF,*FLOOR5ASKING;
@end

e：我无法在新项目中重现错误.
