我试图改变保存图像的文件夹路径。 (从我的文件夹到您的文件夹)
我写的代码如下。如何更改保存图片的文件夹路径?
当我执行下面的代码时,发生错误。 我认为它试图从更改前的文件夹加载。
如何从已更改的文件夹加载图像文件? 请帮忙。 :o
// image loading.
UIImage *image1 = [UIImage imageNamed:@"alarm.png"];
UIImageView *imageView1 = [[UIImageView alloc] initWithImage:image1];
imageView1.center = CGPointMake(100, 100);
[self.view addSubview:imageView1];
// get document path.
NSFileManager *fileManager = [NSFileManager defaultManager];
NSArray *appsDirectory = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
NSString *documentPath = [appsDirectory objectAtIndex:0];
// create myFolder path.
NSString *myFolderPath = [documentPath stringByAppendingPathComponent:@"myFolder"];
if ([fileManager createDirectoryAtPath:myFolderPath withIntermediateDirectories:YES attributes:nil error:nil]){
NSLog(@"success");
}
else {
NSLog(@"failed");
}
// write image to [email protected] file.
NSData *imageData = [NSData dataWithData:UIImagePNGRepresentation(image1)];
NSString *saveName = @"[email protected]";
NSString *savePath = [myFolderPath stringByAppendingPathComponent:saveName];
[imageData writeToFile:savePath atomically:YES];
// load from saved the image1 to image2
UIImage *image2 = [UIImage imageWithContentsOfFile:savePath];
// change folderpath from myfolder to yourfolder
NSString *yourFolderPath = [documentPath stringByAppendingPathComponent:@"yourFolder"];
if ([fileManager moveItemAtPath:myFolderPath toPath:yourFolderPath error:NULL]){
NSLog(@"USER folder success");
}
else {
NSLog(@"USER folder fail");
}
// attach image2 to self.view
UIImageView *imageView = [[UIImageView alloc] initWithImage:image2];
imageView.center = CGPointMake(100, 200);
[self.view addSubview:imageView];
// it's occurs error.
