objective-c - 在与 stringByAppendingString 连接时注入一个字符

Question

有没有办法连接两个字符串并注入一个字符。我有 ：

NSString *firstString = @"http://www.stackoverflow.com";
NSString *secondString = @"supercooloptions";
NSString *result = [firstString stringByAppendingString: secondString];
NSLog(@"the final string with "/" injection = %@", result);

我想要带有“/”的最后一个字符串注入 = www.stackoverflow.com/supercooloptions

Answer 1

您可以使用不同的方法 - 例如，stringWithFormat：

NSString *result = [NSString stringWithFormat:@"%@/%@", firstString, secondString];

Answer 2

对于这种特定情况，请使用stringByAppendingPathComponent:

NSString *result = [firstString stringByAppendingPathComponent:secondString];
