目标C - 对NSMutableStrings使用deleteCharactersInRange

Question

我如何使用deleteCharactersInRange删除NSMutableString的第一个字符？

Answer 1

这并不难......

NSMutableString *a = [NSMutableString stringWithString:@"aString"];
NSRange range;
range.location = 0;
range.length = 1;
[a deleteCharactersInRange:range];

您可以缩短范围创建，如下所示：

NSRange range = {0,1}; // edit: of course 0,1 instead of 1,0, thanks Omar
