祝你好运。+1很好的超快速回答不是它错了,而是为什么要使用NSMutbaleString?@vikingosegundo他没有修改字符串本身,而是创建了一个新的、经过修改的实例。为此,不需要可变字符串。@H2CO3,哦,我应该回去睡觉了。@vikingosegundo或者OP需要修复他的代码;)
NSMutableString *nstring = [NSMutableString stringWithFormat:@"Hello how are you doing"];
NSString *newString = [nstring stringByReplacingOccurrencesOfString:@" " withString:@"+"];
NSLog(@"%@",newString);
NSMutableString *nstring = [NSMutableString stringWithFormat:@"Hello how are you doing"];
NSString *newString = [nstring stringByReplacingOccurrencesOfString:@" " withString:@"+"];
NSLog(@"%@",newString);
