提问by Zohaib
I want to save image in gallery in specific folder. When i click save i am using this code to save image
我想将图像保存在特定文件夹中的画廊中。当我单击保存时，我正在使用此代码来保存图像
- (IBAction)saveImageToGallery:(id)sender {
NSLog(@"SaveImageToGallery");
/*
-----------------------------------------------------------------------
THis will hide button and take screen shot then will show buttons again
-----------------------------------------------------------------------
*/
[AddImagesToCanvasView setHidden:YES];
[ShareOnCanvas setHidden:YES];
[CanvasButtonForRatio setHidden:YES];
for(UIButton *b in self.view.subviews) {
if([b isKindOfClass:[UIButton class]]) {
b.hidden = YES;
}
}
UIGraphicsBeginImageContext(self.view.frame.size);
[self.view.layer renderInContext:UIGraphicsGetCurrentContext()];
UIImage *viewImage = UIGraphicsGetImageFromCurrentImageContext();
UIGraphicsEndImageContext();
for(UIButton *b in self.view.subviews) {
if([b isKindOfClass:[UIButton class]]) {
b.hidden = NO;
}
}
UIImageWriteToSavedPhotosAlbum(viewImage, nil, nil, nil);
}
}
i want that when i click save than it open photos so i can create new album or click on existing album and save that image in that album. How will i do that. Is this possible?
我希望当我单击保存而不是打开照片时，我可以创建新相册或单击现有相册并将该图像保存在该相册中。我将如何做到这一点。这可能吗？

You can use the foolowing code to save the image to specific Album.
您可以使用傻瓜代码将图像保存到特定相册。
ALAssetsLibrary *library = [[ALAssetsLibrary alloc] init];
[library saveImage:image toAlbum:@"Midhun" withCompletionBlock:^(NSError *error) {
if (error!=nil)
{
NSLog(@"Noooo error: %@", [error description]);
}
}];
Here image is your UIImage.
这里的图像是你的UIImage.
Make sure to include AssetsLibrary framework and #import <AssetsLibrary/AssetsLibrary.h>
确保包含 AssetsLibrary 框架和 #import <AssetsLibrary/AssetsLibrary.h>
Please refer this tutorial.

use this line with path
将此行与路径一起使用
[UIImagePNGRepresentation(image) writeToFile:path atomically:YES];
use this bellow code if file type is JPEG
如果文件类型为 JPEG，请使用以下代码
[UIImageJPEGRepresentation(image) writeToFile:path atomically:YES];
