使用文件内容创建和初始化图像对象

通过从指定路径的文件加载图像数据来创建和返回图像对象。

例：

 UIImage *image = [UIImage imageWithContentsOfFile:[[NSBundle mainBundle] pathForResource:[cellCountry objectForKey:@"Country_Flag"] ofType:nil]];

使用数组：

例

 NSMutableArray *imageArray = [[NSMutableArray alloc] init];

for (int imageNumber = 1; self.myPhoto != nil; imageNumber++) {
    NSString *fileName = [NSString stringWithFormat:@"%@.jpg", self.myPhoto];

    // check if a file exists
    if ([UIImage imageNamed:fileName]) {
        // if it exists, add it to the array
        [imageArray addObject:[UIImage imageWithContentsOfFile:[[NSBundle mainBundle]pathForResource:[NSString stringWithFormat:@"%@", fileName] ofType:@""]]];
    } else {
        break;
    }
}

//Using image array for animations here
self.myImageView.animationImages = imageArray;
