Question

我尝试附加文本但没有成功，直到我尝试了这个：

NSString *n_result = @"";
n_result = [n_result stringByAppendingString:[NSString stringWithFormat:@"The number "]];
    n_result = [n_result stringByAppendingString:[NSString stringWithFormat:@"%@ ", n_analyze]];
    n_result = [n_result stringByAppendingString:[NSString stringWithFormat:@", has "]];
    n_result = [n_result stringByAppendingString:[NSString stringWithFormat:@"%i ", steps]];
    n_result = [n_result stringByAppendingString:[NSString stringWithFormat:@"steps to reach 1"]];

问题是，必须有一种更简单的方法。但我不知道怎么做。谁能帮我这个？我一直在寻找如何做到这一点“更好”。

Answer 1

[NSString stringWithFormat:@"The number %@ , has %i steps to reach 1", n_analyze, steps]

Answer 2

是的，有一种稍微简单的方法。使用NSMutableString

的实例

NSMutableString *mutableString = [NSMutableString stringWithFormat:@"The number "];
[mutableString appendFormat:@"%@ ", n_analyze];

// etc..

使用变量附加文本目标C.
