如何从另一个NSString删除NSString的文本

Question

For example:

NSString *sentence = @"My name is Roman";
NSString *name  = @"Roman";

Is there way to delete name 's text from sentence string?

Answer 1

NSString* result = [sentence stringByReplacingOccurrencesOfString:name withString:@""];

Answer 2

是

sentence = [sentence stringByReplacingOccurrencesOfString:name withString:@""];

Answer 3

Alternatively, you can use substringWithRange: like so:

NSString *finalString = [sentence substringWithRange:NSMakeRange(3, 16)];
