Question

我正在尝试从plist文件中创建一个对象数组（animalImages），该文件包含要从我的资源文件夹中提取的图像的名称。我尝试使用for循环单独添加每个图像但在某种程度上迷失在逻辑中。这就是我所拥有的：

NSString *images = [[NSBundle mainBundle] pathForResource:@"images" ofType:@"plist"]; //string with resource path            

animalImageNames = [[NSMutableArray alloc] initWithContentsOfFile:images]; //array with file names

int i;
int j = 10;

for (i=0; i <=j; i++) {
animalImages = [[NSArray alloc] initWithObjects:        
                [[UIImageView alloc] initWithImage:[UIImage imageNamed:@"%@.png",[animalImageNames objectAtIndex:i]]]];
}

我想，一旦我得到答案，我可能会打我的头，但我只是对这段代码的initWithImage部分中的操作顺序感到困惑。

Answer 1

NSString *images = [[NSBundle mainBundle] pathForResource:@"images" ofType:@"plist"];

// need the names for just now. creating an autoreleased one
// and no need to be mutable
NSArray *animalImageNames = [NSArray arrayWithContentsOfFile:images];

// this array will contain the images
// need to release this when you are done
NSMutableArray *animalImages = [[NSMutableArray alloc] init];   

// loop through all names from the plist and add image to the array
for (NSInteger i = 0; i &lt; [animalImageNames count]; i++) {
    NSString *name = [animalImageNames objectAtIndex:i];
    [animalImages addObject:[UIImage imageNamed:[NSString stringWithFormat:@"%@.png", name]]];
}

可能有一些小的错误，因为我还没有编译代码。

使用plist文件中的图像填充数组
