NSMutableArray insertObject:atIndex:问题

[英]NSMutableArray insertObject:atIndex: problems

我有这个方法的问题。 我有11个这样名字的图像:Articulo 1.png,Articulo 2.png等我不知道为什么,但我的图像阵列只有最后一张图像。 难道我做错了什么?

这是我的例子:

NSMutableArray imagenesA = [[NSMutableArray alloc]init];
NSMutableDictionary *dict = [[NSMutableDictionary alloc] init];
UIImage *image = [[UIImage alloc]init];
UIImageView *imageView = [[UIImageView alloc]init];
NSMutableString *name = [[NSMutableString alloc]init];
NSMutableString *name2 = [[NSMutableString alloc]init];

for (int y = 0; y < 11; y++)  {

    name = [NSMutableString stringWithFormat:@"Articulo %d.png",y+1];
    image = [UIImage imageNamed:name];
    imageView = [[UIImageView alloc] initWithImage:image];
    name2 = [NSMutableString stringWithFormat:@"Articulo %d",y+1];
    [dict  setObject:name2  forKey:@"nombre"];
    [dict  setObject:imageView forKey:@"imagen"];

    [imagenesA insertObject:dict atIndex:y];

    // show all dictionarys
    NSLog(@"DICT: %@", dict);
}

// show index 0 element --> must be Articulo 1 but...
NSDictionary *d = [[NSDictionary alloc] 
                    initWithDictionary:[imagenesA objectAtIndex:0]]; 
NSLog(@"*********************%@***********************",d);

控制台响应:

是。 @albertamg在上面的评论中是正确的。 你的for循环应该如下所示。

for (int y = 0; y < 11; y++)  {

    // Other codes here

    NSMutableDictionary *dict = [NSMutableDictionary dictionary];
    [dict  setObject:name2  forKey:@"nombre"];
    [dict  setObject:imageView forKey:@"imagen"];
    [imagenesA insertObject:dict atIndex:y];
}
