iphone - 将图像存储在数组中

Question

我正在尝试将图像存储在名为“_images” 的数组中，但是如果我使用NSLog()查看存储在图像数组中的数据，则只会获得一个图像。你们能帮我吗？这是我的代码:

_images =[NSMutableArray arrayWithObject:[UIImage imageNamed:@"logo1.png"]];
_images =[NSMutableArray arrayWithObject:[UIImage imageNamed:@"logo2.png"]];
_images =[NSMutableArray arrayWithObject:[UIImage imageNamed:@"logo3.png"]];
_images =[NSMutableArray arrayWithObject:[UIImage imageNamed:@"logo4.png"]];
_images =[NSMutableArray arrayWithObject:[UIImage imageNamed:@"logo5.png"]];
_images =[NSMutableArray arrayWithObject:[UIImage imageNamed:@"logo6.png"]];
_images =[NSMutableArray arrayWithObject:[UIImage imageNamed:@"logo7.png"]];
_images =[NSMutableArray arrayWithObject:[UIImage imageNamed:@"logo8.png"]];
_images =[NSMutableArray arrayWithObject:[UIImage imageNamed:@"logo9.png"]];
_images =[NSMutableArray arrayWithObject:[UIImage imageNamed:@"logo10.png"]];
_images =[NSMutableArray arrayWithObject:[UIImage imageNamed:@"logo11.png"]];
_images =[NSMutableArray arrayWithObject:[UIImage imageNamed:@"logo12.png"]];
_images =[NSMutableArray arrayWithObject:[UIImage imageNamed:@"logo13.png"]];
_images =[NSMutableArray arrayWithObject:[UIImage imageNamed:@"logo14.png"]];
_images =[NSMutableArray arrayWithObject:[UIImage imageNamed:@"logo15.png"]];
_images =[NSMutableArray arrayWithObject:[UIImage imageNamed:@"logo16.png"]];

NSLog(@"ha ha ha:%d",_images.count);

您正在每一行上创建一个新数组；您将丢失对旧数组的引用，从而丢失其中的图像。您想将新图像添加到现有阵列。将第2行及以下更改为:

[_images addObject:[UIImage imageNamed:...]];
