OC字符串拼接与分割实践-优快云博客

该博客通过一个OC代码示例展示了如何将两个字符串的单词进行交叠拼接。首先，使用componentsSeparatedByString方法分割字符串，然后将分割后的数组元素交替添加到新的数组中，最后将剩余元素添加到数组并用componentsJoinedByString方法将数组元素合并成新的字符串。

int main(int argc, const char * argv[]) {
    @autoreleasepool {
        //有两个字符串@"I am a good girl";@"You are a bad boy"; 将这两个字符串单词,交叠,形成系的字符串 @"I You am are a a good bad girl boy"
        NSString *str1 = @"I am a good girl";
        NSString *str2 = @"You are a bad boy hello world";
        NSArray *array1 = [str1 componentsSeparatedByString:@" "];
        NSArray *array2 = [str2 componentsSeparatedByString:@" "];
        NSMutableArray *mulArray = [NSMutableArray array];
        NSInteger len1 = [array1 count];
        NSInteger len2 = [array2 count];
        NSInteger len = len1>len2?len2:len1;

        for (NSInteger i=0;i<len; i++) {
            [mulArray addObject:[array1 objectAtIndex:i]];
            [mulArray addObject:[array2 objectAtIndex:i]];
        }
        NSArray *subArray = nil;
        subArray = len1>len2?[array1 subarrayWithRange:NSMakeRange(len, len1-len)]:[array2 subarrayWithRange:NSMakeRange(len, len2 -len)];
        [mulArray addObjectsFromArray:subArray];
        NSLog(@"%@", mulArray);
        NSString *str = [mulArray componentsJoinedByString:@" "];
        NSLog(@"%@", str);
    }
    return 0;
}
