如何从字符串中删除特定单词？

Question

我有一个NSString*str,有价值@"我喜欢编程和游戏." 我必须从我的字符串中删除"我""喜欢"和"和",所以它应该看起来像"编程游戏"

我怎么能这样做,任何想法？

Answer 1

NSString *newString = @"I like Programming and gaming.";
NSString *newString1 = [newString stringByReplacingOccurrencesOfString:@"I" withString:@""];
NSString *newString12 = [newString1 stringByReplacingOccurrencesOfString:@"like" withString:@""];
NSString *final = [newString12 stringByReplacingOccurrencesOfString:@"and" withString:@""];

分配给错误的字符串变量现在编辑它很好

NSLog(@"%@",final);

输出:编程游戏

Answer 2

NSString * newString = [@"I like Programming and gaming." stringByReplacingOccurrencesOfString:@"I" withString:@""];
newString = [newString stringByReplacingOccurrencesOfString:@"like" withString:@""];
newString = [newString stringByReplacingOccurrencesOfString:@"and" withString:@""];

NSLog(@"%@", newString);
