xcode - 如何用文本字符串添加 [NSArray arrayWithObjects NSNumber numberWithInt:]？

Question

如何在 NSNumber 中添加文本？我找不到解决此问题的解决方案。你这是怎么做到的？

NSString *myInt = interestRate.text;

NSArray *vals = [NSArray arrayWithObjects:
                 [NSNumber numberWithInt:30],
                 [NSNumber numberWithInt: [NSString stringWithFormat:@"%@", myInt]],
                 [NSNumber numberWithInt:20],
                 [NSNumber numberWithInt:56],
                 [NSNumber numberWithInt:70],
                 [NSNumber numberWithInt:34],
                 [NSNumber numberWithInt:43],
                 nil];

我在为每一个添加文本时遇到问题。

利用：

NSString *myInt = interestRate.text;

NSArray *vals = [NSArray arrayWithObjects:
                 [NSNumber numberWithInt:30],
                 [NSNumber numberWithInt:[myInt intValue]],
                 [NSNumber numberWithInt:20],
                 [NSNumber numberWithInt:56],
                 [NSNumber numberWithInt:70],
                 [NSNumber numberWithInt:34],
                 [NSNumber numberWithInt:43],
                 nil];
