Objective C - 替换 NSString 中的字符串部分

使用 Objective C 替换 NSString 中的字符串部分是一项常见的编程任务。在许多情况下，我们需要将一个字符串中的特定部分替换为另一个字符串。Objective C 提供了一些方法和函数来执行这项任务，使我们能够轻松地完成字符串替换操作。

objective-c
NSString *originalString = @"Hello, World!";
NSString *replacementString = @"Objective C";
NSString *newString = [originalString stringByReplacingOccurrencesOfString:@"World" withString:replacementString];
NSLog(@"%@", newString);

objective-c
NSString *originalString = @"I love apples. Apples are delicious!";
NSString *replacementString = @"oranges";
NSString *newString = [originalString stringByReplacingOccurrencesOfString:@"apples" withString:replacementString];
NSLog(@"%@", newString);

objective-c
NSString *originalString = @"I love apples. Apples are delicious!";
NSString *replacementString = @"oranges";
NSString *newString = [originalString stringByReplacingOccurrencesOfString:@"apples" withString:replacementString];
newString = [newString stringByReplacingOccurrencesOfString:@"Apples" withString:replacementString];
NSLog(@"%@", newString);

objective-c
NSString *originalString = @"I love apples. Apples are delicious!";
NSString *replacementString = @"oranges";
NSString *newString = [originalString stringByReplacingOccurrencesOfString:@"love apples" withString:replacementString];
