如何将图像保存到沙箱 - iPhone SDK [英] How do I save an image to the sandbox - iPhone SDK

问题描述

我从UIImagePicker中删除了一个图像，我想暂时将它保存到沙箱环境中，在文档文件夹或其他类似的等效文件中。但是，我不知道该怎么做，请有人帮帮我吗？谢谢

I have pulled an image out of the UIImagePicker thingy, and I would like to temporarily save it to the sandbox environment, in either the documents folder, or some other similar equivalent. However, I do not know how to do this, please could someone help me? Thanks

目前图片是UIImage

At the moment the image is a UIImage

推荐答案

正在保存图像：

-(void)saveImage:(UIImage*)image{
    NSString  *imagePath = [NSHomeDirectory() stringByAppendingPathComponent:@"Documents/someImageName.png"];

   [UIImagePNGRepresentation(image) writeToFile:imagePath atomically:YES];

}

加载图片

-(UIImage)loadImage{

   NSString  *imagePath = [NSHomeDirectory() stringByAppendingPathComponent:@"Documents/someImageName.png"];

   UIImage *image = [UIImage imageWithContentsOfFile:imagePath];
}
