提问by kingston
I'm trying to store my images in an array named "_images"but if I use NSLog()to view the data stored in image array, I get only one image. Would you guys help me out? Here's my code:
我试图将我的图像存储在一个名为“_images”的数组中，但如果我NSLog()用来查看存储在图像数组中的数据，我只会得到一张图像。你们会帮我吗？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);

You're creating a new array on each line; you lose the reference to the old array and thus the image within it. You want to add new images to an existing array. Change lines 2 and onwards to the following:
你在每一行上创建一个新数组；你失去了对旧数组的引用，从而失去了其中的图像。您想向现有阵列添加新图像。将第 2 行及以后更改为以下内容：
[_images addObject:[UIImage imageNamed:...]];

You can also use a loop:
您还可以使用循环：
_images = [[[NSMutableArray alloc] init] autorelease];
for (int i=1; i<=16; ++i) {
[_images addObject:[UIImage imageNamed:[NSString stringWithFormat:@"logo%d.png",i]]];
}
