直接将NSNumber转换为NSString

Question

如何？

·H

@property (nonatomic, strong) NSNumber *seasonRoundN;
@property (nonatomic, strong) NSString *seasonRound;

的.m

_weMeetAgain = [NSNumber numberWithInt:13];
_seasonRound = [NSString stringWithFormat:_weMeetAgain]; // incompatible :S

应该更好地查看参考文献:(以下答案）

_weMeetAgain = [NSNumber numberWithInt:17];
_seasonRound = [NSString stringWithFormat:@"%@", _weMeetAgain];

帮助：P，谢谢。

Answer 1

[NSString stringWithFormat:@"%d", [_weMeetAgain intValue]]

Answer 2

只需使用NSNumber实例方法stringValue。

_seasonRound = [_weMeetAgain stringValue];
