将NSString添加到数组中每个对象的末尾

Question

我有这样一个数组:

self.youtubeVideos = [NSArray arrayWithObjects: 

                      @"http://example.com/index.php?number=1&keyword=", 
                      @"http://example.com/index.php?number=2&keyword=",

                      nil];

我想在数组中的每个对象的末尾添加一个名为"searchKeyword"的NSString.

我该怎么做呢？

谢谢!

Answer 1

创建一个可变数组,然后逐步执行并修改每个元素.

NSMutableArray* fixedUrls = [NSMutableArray arrayWithCapacity:self.youtubeVideos.count];    

for (NSString* url in self.youtubeVideos)
{
    [fixedUrls addObject:[url stringByAppendingString:searchKeyword]];
}

self.youtubeVideos = fixedUrls;
