方法

Question

在xCode中，当我使用po进行调试时，我收到此错误。

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

我看到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, expected 1, 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, expected 1, 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。可能导致这种情况的任何想法！？

e：使用po item.CNUMBER给我一个类似于

的电话号码

item只是我用来解析json响应的模型，没有涉及任何方法。

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。

感谢@danh，我们发现问题是一个NSString扩展方法。删除它允许我像平常一样进行调试。
