if([UIImagePickerController isSourceTypeAvailable:UIImagePickerControllerSourceTypePhotoLibrary])
{
    UIImagePickerController *picker=[[UIImagePickerController alloc]init];
    picker.delegate=(id)self;
    picker.allowsEditing=YES;

    picker.sourceType=UIImagePickerControllerSourceTypePhotoLibrary;
