How does one create a dynamic thumbnail grid?
How is a grid created with thumbnails of images like the photo app on iphone?
How are these spaces arranged dynamically? e.g. adding and removing thumbnails.
this is my simple grid view app
- (void)viewDidAppear:(BOOL)animated {

if (temp ==1){

definitely if u apply this logic. u get succeed

I have UITableView and its delegates are set via xib as shown in below image.
I have put some LOAD MORE CODE in method so that when user scrolldown, it sends request to server and load more values.
- (void)scrollViewDidScroll:(UIScrollView *)scrollView
{
NSLog(#"Veer Suthar Scrolling the view");
CGPoint offset = scrollView.contentOffset;
CGRect bounds = scrollView.bounds;
CGSize size = scrollView.contentSize;
UIEdgeInsets inset = scrollView.contentInset;
float y = offset.y + bounds.size.height - inset.bottom;
float h = size.height;
float reload_distance = 15;
if(y > h + reload_distance)
{
//Call the Method to load More Data...
AppDelegate *appDelegate = (AppDelegate*)[[UIApplication sharedApplication]delegate];
if ([appDelegate.reach isReachable])
{
if (onceCallTheLoadMore) {
onceCallTheLoadMore = NO;
int startCountValue = [vouchersArray count]+1;
int endCountValue = [vouchersArray count] + 10;
startCount = [[NSString alloc] initWithString:[NSString stringWithFormat:#"%d", startCountValue]];
endCount = [[NSString alloc] initWithString:[NSString stringWithFormat:#"%d", endCountValue]];
NSString *totalCount = [[NSUserDefaults standardUserDefaults] valueForKey: #"totalCountOfFeaturedVouchers"];
int totalCountValue = [totalCount intValue];
if (endCountValue > totalCountValue) {
////
onceCallTheLoadMore = YES;
}else{
[self featuredWebService];
}
//Veer, call here method for load more
}else{
}
}
}
}
Here this methods gets called when View Loads.
how can I prevent it from calling when view loads.
I tried
[self.tableview setDelegate:nil]; //Used in ViewWillAppear and again in ViewDidLoad its set to SELF.
But its not working fine.

In your viewWillApear method, you have [self.tableView reloadData] - this is causing the scrollView to call its delegate scrollViewDidScroll

And when user long press button than it will be deleted...

// NSLog(#"blabel long pressed");
UIAlertView *alert = [[UIAlertView alloc] initWithTitle:#"Delete Label" message:#"Want delete label" delegate:self cancelButtonTitle:#"No" otherButtonTitles:#"Yes",nil];
[alert show];
}
else {

}
}
- (void)alertView:(UIAlertView *)alertView clickedButtonAtIndex:(NSInteger)buttonIndex
{

if([title isEqualToString:#"Yes"])
{
ExampleAppDataObject* theDataObject = [self theAppDataObject];
if (theDataObject.count!=0) {
theDataObject.count = theDataObject.count-1;
}
addLabel.enabled = YES;
[labelResizableView removeFromSuperview];
// NSLog(#"yes btn tapped");
}
}
but now when i longpree blabel than still clabel is deleted and it will never delete blabel.thanx in advance.
Use the Tag property to remove the labelResizableView.
-(void)addLabel:(id)sender
{
labelResizableView = [[UserResizableView alloc] initWithFrame:imageFrame];
labelResizableView.tag = 100;
}
- (void)alertView:(UIAlertView *)alertView clickedButtonAtIndex:(NSInteger)buttonIndex
{
NSString *title = [alertView buttonTitleAtIndex:buttonIndex];
if([title isEqualToString:#"Yes"])
{
ExampleAppDataObject* theDataObject = [self theAppDataObject];
if (theDataObject.count!=0) {
theDataObject.count = theDataObject.count-1;
}
addLabel.enabled = YES;
UILabel *tempLabel = (UILabel *)[self.view viewWithTag:100];
if(tempLabel)
[tempLabel removeFromSuperview];
}
}
hope this code help you :)
NSArray *subArray = [self.view subviews];
if([subArray count] != 0) {
for(int i = 0 ; i < [subArray count] ; i++) {
[[subArray objectAtIndex:i] removeFromSuperview];
}
}
To add control in your view:
[self.view addsubview:yourcontrolid];
ex:
[self.view addsubview:labelid];
To add control from your view:
[controlid removefromsuperview];
ex
[labelid removefromsuperview];
you are adding with :
[self.view addSubview:labelResizableView];
than remove it the labelResizableView, and release the clabel or blabel, whatever is in your case.
Maybe this gives an example
It is because your code
else if (theDataObject.count == 2) {
is calling and in this code you are adding
labelResizableView.contentView = clabel;
and then you are adding this to you view
[self.view addSubview:labelResizableView];
So when you are deleting labelResizableView
[labelResizableView removeFromSuperview];
So the result is you are adding labelResizableView 2 times and remove the labelResizableView which have clabel.
Currently it is saving all images but i want to save only the one which is long pressed not all images in one shot only the one user selects

How to code for that
Thanks for help
In the handleLongPress: function, use this:
UIGestureRecognizer *gestureRecognizer;
CGPoint gesturePoint = [gestureRecognizer locationInView:self.view];
Then check all of your buttons using a for loop like you have there. Use this to check if it is the pressed image:
if(CGRectContainsPoint(myButton.frame,gesturePoint)){
//save the image stored in myButton
//break will exit the for loop early, so if the view comes early in the list,
//it doesn't have to check the rest.
break;

I want create 32 views like above view. so that what i modify in my code so i get this view? I shown code below
- (void)loadView {
[super loadView];
self.view.backgroundColor = [UIColor redColor];
UIScrollView *scroll = [[UIScrollView alloc] initWithFrame:CGRectMake(0, 0, self.view.frame.size.width, self.view.frame.size.height)];
scroll.pagingEnabled = YES;
NSInteger numberOfViews = 33;
[btnMenu setTag:0 ];
for (int i = 1; i < numberOfViews; i++) {
CGFloat yOrigin = i * self.view.frame.size.width;
UIView *awesomeView = [[UIView alloc] initWithFrame:CGRectMake(yOrigin, 0, self.view.frame.size.width, self.view.frame.size.height)];
btnMenu = [UIButton buttonWithType:UIButtonTypeCustom];
//NSData *data =UIImageJPEGRepresentation(, 1);
[btnMenu setBackgroundImage:[UIImage imageNamed:[NSString stringWithFormat:#"page-%d.jpg",i]] forState:UIControlStateNormal];
CGRect frame = btnMenu.frame;
frame.size.width=320;
frame.size.height=420;
frame.origin.x=0;
frame.origin.y=0;
btnMenu.frame=frame;
[btnMenu setTag:i];
btnMenu.alpha = 1;
[btnMenu addTarget:self action:#selector(btnSelected:) forControlEvents:UIControlEventTouchUpInside];
[awesomeView addSubview:btnMenu];
[scroll addSubview:awesomeView];
[awesomeView release];
}
scroll.contentSize = CGSizeMake(self.view.frame.size.width * numberOfViews, self.view.frame.size.height);
[self.view addSubview:scroll];
[scroll release];}
-(IBAction)btnSelected:(id)sender{
UIButton *button = (UIButton *)sender;
int whichButton = button.tag;
NSLog(#"Current TAG: %i", whichButton);
if(whichButton==1)
{
first=[[FirstImage alloc]init];
[self.navigationController pushViewController:first animated:YES];
}
}
scroll.contentSize = CGSizeMake(self.view.frame.size.width * numberOfViews, self.view.frame.size.height);
write this line in your code before the for loop.
