objective-c - 在目标 c 中用空格替换单词

Question

我有一个这样的字符串：

NSString *test = @"This is a test string";

我想用空格替换“测试”字，如下所示：

“这是一个字符串”

我怎么能做这样的事情？

我试过使用这个功能

test = [test stringByReplacingOccurrencesOfString:@"test" withString:@"    "];

并没有正常工作。

Answer 1

NSString *test = @"This is a test string";
test = [test stringByReplacingOccurrencesOfString:@" test" withString:@""];
NSLog(@"%@",test);

it should work, hope it helps. happy coding :)

Answer 2

NSString *test = @"This is a test string";
test = [test stringByReplacingOccurrencesOfString:@"test" withString:@""];
NSLog(@"%@",test);

Use this. No need to give space. it will replace that word with empty space.

Answer 3

使用 NSMutableString 代替 NSString.Repalce NSString *test = @"This is a test string" with NSMutableString *test = @"This is a test string";
