 NSLog(@"Ci sono %d categorie",category.count);
 for(int c=0; c<category.count; c++){
 CategoryArray * element =[category objectAtIndex:c];
 NSLog(@"******************************");
 NSLog(@"Titolo %@",element.label);
 NSLog(@"Source %@",element.url);
 NSLog(@"******************************");
 [element release];

这是我的代码!我需要删除所有重复数组...我使用此代码,但我不明白为什么它不起作用.

uniquearray = [[NSSet setWithArray:category] allObjects];

是否可以使用某些系统API调用iphone sdk中的预定数字？

我想创建一个像这样的表视图,右边有一个徽章.有人可以建议我怎样才能得到这个结果？谢谢
