It works fine for the first time but the second time app is crashed leaving memory warning level=1
I google around and tried all possible ways but no use
Below is the code i used in my app
UIImagePickerController *imgpicker;
#property(nonatomic,retain) UIImagePickerController *imgpicker;
#synthesize imgpicker;
if(actionSheet.tag==1)
{
NSLog(#"button index:%i",buttonIndex);
if(buttonIndex == 0)
{ NSLog(#"button index for camera:%i",buttonIndex);
if(self.imgpicker==nil){
self.imgpicker=[[UIImagePickerController alloc]init];
self.imgpicker.delegate =self;
self.imgpicker.sourceType=UIImagePickerControllerSourceTypeCamera;
}
[self presentModalViewController:self.imgpicker animated:YES];
[imgpicker release];
return;
}
}
- (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info
{
NSLog(#"didFinishPickingMediaWithInfo editing info:%#",info);
UIImage *image = [info valueForKey:UIImagePickerControllerOriginalImage];
imageview = [[UIImageView alloc] initWithFrame:CGRectMake(65, 10, 75, 75)];
NSData *newjpg = UIImageJPEGRepresentation(image, 0.5);
[imageview setImage:[UIImage imageWithData:newjpg]];
[scrollView addSubview:imageview];
[self.view addSubview:scrollView];
[[picker parentViewController] dismissModalViewControllerAnimated:YES];
}
Please help me

Answer 1

Try changing this:
self.imgpicker=[[UIImagePickerController alloc]init];
to this:
self.imgpicker=[[[UIImagePickerController alloc]init] autorelease];
and remove this line:
[imgpicker release];
If you're showing the image picker more than once, you're leaking memory from the image view that gets allocated every time the picker finishes.
You're also adding the image view to the scroll view and the scroll view to the view controller's view every time. You just need to do it once, and the update the image property on the image view.
Try this:
- (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info
{
NSLog(#"didFinishPickingMediaWithInfo editing info:%#",info);
UIImage *image = [info valueForKey:UIImagePickerControllerOriginalImage];
if (imageview == nil) {
imageview = [[UIImageView alloc] initWithFrame:CGRectMake(65, 10, 75, 75)];
[scrollView addSubview:imageview];
[self.view addSubview:scrollView];
}
NSData *newjpg = UIImageJPEGRepresentation(image, 0.5);
[imageview setImage:[UIImage imageWithData:newjpg]];
[[picker parentViewController] dismissModalViewControllerAnimated:YES];
}

Please create UIImagePickerController object in your AppDelegate class and initialize in your AppDidFinishloading method : didFinishLaunchingWithOptions. Realese it on appDelegate dealloc method.
You can access it in your needed view controller Page from appdelegate class.
Please do not create evertytime UIImagePickerController object when u needed and realese it.
This might help you.

Please use this code :
App Delegate
// .h
#import <UIKit/UIKit.h>
#interface MyProjectAppDelegate : NSObject <UIApplicationDelegate> {
UIImagePickerController *image_picker;
UIWindow *window;
UINavigationController *navigationController;
}
#property(nonatomic, retain) UIImagePickerController *image_picker;
#property (nonatomic, retain) IBOutlet UIWindow *window;
#property (nonatomic, retain) IBOutlet UINavigationController *navigationController;
-(void)initializeImagePickerView;
#end
// .m
#import "MyProjectAppDelegate.h"
#import "RootViewController.h"
#implementation MyProjectAppDelegate
#synthesize window;
#synthesize navigationController,image_picker;
#pragma mark -
#pragma mark Application lifecycle
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
// Override point for customization after application launch.
[self initializeImagePickerView];
// Set the navigation controller as the window's root view controller and display.
self.window.rootViewController = self.navigationController;
[self.window makeKeyAndVisible];
return YES;
}
-(void)initializeImagePickerView
{
// Picker View
self.image_picker = [[UIImagePickerController alloc] init];
self.image_picker.allowsImageEditing = YES;
}
- (void)dealloc {
[image_picker release];
[navigationController release];
[window release];
[super dealloc];
}
#end
//RootView Controller
// .h
#import <UIKit/UIKit.h>
#import "MyProjectAppDelegate.h"
#interface RootViewController : UIViewController <UIImagePickerControllerDelegate,UINavigationControllerDelegate>{
MyProjectAppDelegate *appDelegate;
}
-(IBAction)btnPhotoPressed:(id)sender;
#end
// .m
#import "RootViewController.h"
#implementation RootViewController
#pragma mark -
#pragma mark View lifecycle
- (void)viewDidLoad {
[super viewDidLoad];
appDelegate = (MyProjectAppDelegate *)[[UIApplication sharedApplication] delegate];
}
-(IBAction)btnPhotoPressed:(id)sender
{
appDelegate.image_picker.sourceType=UIImagePickerControllerSourceTypePhotoLibrary;
appDelegate.image_picker.delegate=self;
[self presentModalViewController:appDelegate.image_picker animated:YES];
}
#pragma mark UIImagePickerController delegate
- (void) imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info
{
// Access the uncropped image from info dictionary
UIImage *imgCapturePhoto = [info objectForKey:#"UIImagePickerControllerOriginalImage"];
// You can use image here
[self dismissModalViewControllerAnimated:YES];
}
-(void)imagePickerControllerDidCancel:(UIImagePickerController *) picker
{
[picker dismissModalViewControllerAnimated:YES];
}
- (void)dealloc {
[super dealloc];
}
This will definitely help u.
