saving images inside apps - objective-c

Question

Hey guys I'm coding a tweak and need a help with expert users (using theos and logos mixed with objective C) I'm adding an option to save photos in instagram (third party app) i added a save button
-(void)actionSheetDismissedWithButtonTitled:(NSString *)title{if([title isEqualtToString:#"Save"])
added the button successfully and prepared the save image code which is the following:
%hook IGFeedItemActionCell -(void)actionSheetDismissedWithButtonTitled:(NSString *)title { if ([title isEqualToString:#"Save"]) IGFeedItem *post = self.feedItem;{ UIImageWriteToSavedAlbum(post, nil,nil,nil);UIAlertView *alert = [[UIAlertView alloc]initWithTitle:#"Image Saved" message:#"The image was saved."delegate:self cancelButtonTitle:#"Okay" otherButtonTitles:nil, nil];[alert show];} } %end
my question is how to link the saving code with the pictures in the app (the class for pictures is IGFeedItemPhotoView)
thanks in advance

Answer 1

So I wrote a full program that does what you want and something extra :)
#import <UIKit/UIKit.h>
#interface IGPost: NSObject{}
#property int mediaType;
+ (int)videoVersionForCurrentNetworkConditions;
+ (int)fullSizeImageVersionForDevice;
- (id)imageURLForImageVersion:(int)arg1;
- (id)videoURLForVideoVersion:(int)arg1;
#end
#interface IGFeedItem: IGPost{}
#end
#interface IGFeedItemActionCell: NSObject{}
#property (nonatomic,retain) IGFeedItem* feedItem;
-(void)actionSheetDismissedWithButtonTitled:(id)arg1;
#end
%hook IGFeedItemActionCell
-(void)actionSheetDismissedWithButtonTitled:(id)arg1 {
NSString *title = (NSString *)arg1;
if ([title isEqualToString:#"Save"]) {
IGFeedItem *post = self.feedItem;
if (post.mediaType == 1) {
int version = [[post class] fullSizeImageVersionForDevice];
NSURL *link = [post imageURLForImageVersion:version];
NSData *imageData = [NSData dataWithContentsOfURL:link];
UIImage *image = [UIImage imageWithData:imageData];
UIImageWriteToSavedPhotosAlbum(image, nil,nil,nil);
UIAlertView *alert = [[UIAlertView alloc]initWithTitle:#"Image Saved" message:#"The image was saved."delegate:self cancelButtonTitle:#"Okay" otherButtonTitles:nil, nil];
[alert show];
}
else {
int version = [[post class] videoVersionForCurrentNetworkConditions];
NSURL *link = [post videoURLForVideoVersion:version];
NSURLSessionTask *download = [[NSURLSession sharedSession] downloadTaskWithURL:link completionHandler:^(NSURL *location, NSURLResponse *response, NSError *error) {
NSURL *documentsURL = [[[NSFileManager defaultManager] URLsForDirectory:NSDocumentDirectory inDomains:NSUserDomainMask] firstObject];
NSURL *tempURL = [documentsURL URLByAppendingPathComponent:[link lastPathComponent]];
[[NSFileManager defaultManager] moveItemAtURL:location toURL:tempURL error:nil];
UISaveVideoAtPathToSavedPhotosAlbum(tempURL.path, nil, NULL, NULL);
}];
[download resume];
UIAlertView *alert = [[UIAlertView alloc]initWithTitle:#"Video Saved" message:#"The video was saved."delegate:self cancelButtonTitle:#"Okay" otherButtonTitles:nil, nil];
[alert show];
}
}
else {
%orig(arg1);
}
}
%end
