在for循环中增加UIImageView变量的数字部分?

好吧,我觉得你在用一种尴尬的方式处理这个问题。
也许最好的办法就是 UIImageView NSArray . 所以在你的类声明中

@property (nonatomic, retain) UIImageView *myPicture1;
@property (nonatomic, retain) UIImageView *myPicture2;
@property (nonatomic, retain) UIImageView *myPicture3;

你会的

@property (nonatomic, retain) NSArray *myPictures;

然后你这样创造它们:

NSMutableArray *myTempArray = [NSMutableArray arrayWithCapacity:3];
for (i=0; i<3; i++)
{
    int g = arc4random() % 19;

    NSString *imagename = [NSString stringWithFormat:@"image%d.jpg",g];
    UIImage *picture = [UIImage imageNamed:imagename];

    UIImageView imageView = [[UIImageView alloc] initWithImage : picture];
    [myTempArray addObject: imageView];
    [imageView release];
}
self.myPictures = [NSArray arrayWithArray: myTempArray];
