I'm trying to fetch the selected image from the array of images.And the selected image should be displayed in new view..
- (void)viewDidLoad{
[super viewDidLoad];
selectedTag = 0;
imagesName = [[NSArray alloc]initWithObjects:#"nature1.jpg",#"nature2.jpg",#"nature3.jpg",#"nature4.jpg",#"nature5.png",#"nature6.jpg",nil];
images = [[NSMutableArray alloc]init];
imageScroll.delegate = self;
imageScroll.scrollEnabled = YES;
int scrollWidth = 768;
imageScroll.contentSize = CGSizeMake(scrollWidth,605);
int xOffset = 0;
for(index=0; index < [imagesName count]; index++)
{
UIButton *img = [UIButton buttonWithType:UIButtonTypeCustom];
img.tag = index;
selectedTag = img.tag;
img.bounds = CGRectMake(10, 10, 50, 50);
img.frame = CGRectMake(50+xOffset, 120, 270, 350);
NSLog(#"image: %#",[imagesName objectAtIndex:index]);
[img setImage:[UIImage imageNamed:[imagesName objectAtIndex:index]] forState:UIControlStateNormal];
[images insertObject:img atIndex:index];
imageScroll.contentSize = CGSizeMake(scrollWidth+xOffset,510);
[imageScroll addSubview:[images objectAtIndex:index]];
xOffset += 370;
[img addTarget:self action:#selector(newView:) forControlEvents:UIControlEventTouchUpInside];
selectedTag = img.tag;
}
}
-(void)newView:(id)sender{
NSLog(#"%#",sender);
int f;
f = [sender tag];
CGRect rec = CGRectMake(0, 0, 250, 250);
[self setView:[[[UIView alloc] initWithFrame:rec] autorelease]];
[[self view] setBackgroundColor:[UIColor grayColor]];
UIImageView *im = [[UIImageView alloc] initWithImage:[imagesName objectAtIndex:f]];
im.bounds = CGRectMake(10, 10, 50, 50);
im.frame = CGRectMake(250, 120, 270, 350);
[[self view] addSubview:im];
}
Can anybody help me to fetch the selected image to another view?? Thanks In Advance..
You are setting string instead of image. Use this piece of code
UIImage *img = [UIImage imageNamed:[imagesName objectAtIndex:f]];
UIImageView *im = [[UIImageView alloc] initWithImage:img];

2I'm working on dropDowns, i'm creating buttons and dropdown tableView dynamically. When i click first button last tableView was opened. But i want to open specific tableView (at a time i want to open only one dropdown).
float y = 0;
float x = (self.answersView.frame.size.width/2)+175;
float Iy = 0;
float Ix = 675;
float Tx = (self.answersView.frame.size.width/2)+175;
float Ty = 0;
for (int i=0; i<self.radioBtnTagArr.count; i++) {
self.dropdownBtn = [UIButton buttonWithType:UIButtonTypeSystem];
self.dropdownBtn.frame = CGRectMake(x, y+30, (self.answersView.frame.size.width/2)-200, 50);
[self.dropdownBtn setTitle:#"0" forState:UIControlStateNormal];
self.dropdownBtn.contentHorizontalAlignment = UIControlContentHorizontalAlignmentLeft;
[self.dropdownBtn setTitleColor:[UIColor colorWithRed:24/255.0 green:56/255.0 blue:131/255.0 alpha:1] forState:UIControlStateNormal];
self.dropdownBtn.titleLabel.font = [UIFont systemFontOfSize:25];
[self.dropdownBtn addTarget:self action:#selector(dropdownBtnTapMethod:) forControlEvents:UIControlEventTouchUpInside];
self.dropdownBtn.backgroundColor = [UIColor lightGrayColor];
[self.scrollView addSubview:self.dropdownBtn];
self.dropdownBtn.tag = [[self.btnTagArr objectAtIndex:i] intValue];
y = y+70;
self.dropdownImageView = [[UIImageView alloc]initWithFrame:CGRectMake(Ix, Iy+50, 20, 10)];
self.dropdownImageView.image = [UIImage imageNamed:#"dropdown.png"];
[self.answersView addSubview:self.dropdownImageView];
Iy = Iy+70;
self.dropdownTableView = [[UITableView alloc]initWithFrame:CGRectMake(Tx, Ty+80, (self.answersView.frame.size.width/2)-200, 50) style:UITableViewStylePlain];
self.content = #[ #"Monday", #"Tuesday", #"Wednesday",#"Thursday",#"Friday",#"Saturday",#"Sunday"];
self.dropdownTableView.delegate = self;
self.dropdownTableView.dataSource = self;
[self.answersView addSubview:self.dropdownTableView];
Ty = Ty+70;
self.dropdownTableView.hidden = YES;
}
//The event handling method
- (void)dropdownBtnTapMethod:(UIButton *) sender {
if (self.dropdownTableView.hidden == YES) {
self.dropdownTableView.hidden = NO;
} else {
self.dropdownTableView.hidden = YES;
}
}
And how to set table view height dynamically.
Try this :
NSMutableArray *arrTableview; // make global
In ViewDidLoad
arrTableview = [NSMutableArray New];
Change in following method
for (int i=0; i<self.radioBtnTagArr.count; i++) {
self.dropdownBtn = [UIButton buttonWithType:UIButtonTypeSystem];
self.dropdownBtn.tag = i; // add this line
self.dropdownBtn.frame = CGRectMake(x, y+30, (self.answersView.frame.size.width/2)-200, 50);
[self.dropdownBtn setTitle:#"0" forState:UIControlStateNormal];
self.dropdownBtn.contentHorizontalAlignment = UIControlContentHorizontalAlignmentLeft;
[self.dropdownBtn setTitleColor:[UIColor colorWithRed:24/255.0 green:56/255.0 blue:131/255.0 alpha:1] forState:UIControlStateNormal];
self.dropdownBtn.titleLabel.font = [UIFont systemFontOfSize:25];
[self.dropdownBtn addTarget:self action:#selector(dropdownBtnTapMethod:) forControlEvents:UIControlEventTouchUpInside];
self.dropdownBtn.backgroundColor = [UIColor lightGrayColor];
[self.scrollView addSubview:self.dropdownBtn];
//self.dropdownBtn.tag = [[self.btnTagArr objectAtIndex:i] intValue]; // This line commented.
y = y+70;
self.dropdownImageView = [[UIImageView alloc]initWithFrame:CGRectMake(Ix, Iy+50, 20, 10)];
self.dropdownImageView.image = [UIImage imageNamed:#"dropdown.png"];
[self.answersView addSubview:self.dropdownImageView];
Iy = Iy+70;
self.dropdownTableView = [[UITableView alloc]initWithFrame:CGRectMake(Tx, Ty+80, (self.answersView.frame.size.width/2)-200, 50) style:UITableViewStylePlain];
self.content = #[ #"Monday", #"Tuesday", #"Wednesday",#"Thursday",#"Friday",#"Saturday",#"Sunday"];
self.dropdownTableView.delegate = self;
self.dropdownTableView.dataSource = self;
[self.answersView addSubview:self.dropdownTableView];
[arrTableview addObject :self.dropdownTableView];
Ty = Ty+70;
self.dropdownTableView.hidden = YES;
}
Selector
- (void)dropdownBtnTapMethod:(UIButton *) sender {
UITableView *tableView =[arrTableview objectAtIndex:sender.tag]
if (tableView.hidden == YES) {
tableView.hidden = NO;
} else {
tableView.hidden = YES;
}
}
I have used the code
imageSlider = [[UIScrollView alloc]initWithFrame:CGRectMake(5, 60, 700, 700)];
imageSlider.pagingEnabled = YES;
imageSlider.showsHorizontalScrollIndicator =NO;
for (int i = 0; i < [myObject count]; i++) {
CGRect frame;
frame.origin.x = imageSlider.frame.size.width * i;
frame.origin.y = 0;
frame.size = imageSlider.frame.size;
NSManagedObject *con = [myObject objectAtIndex:i] ;
UIImage *Image = [UIImage imageWithData:[con valueForKey:#"image"]];
UIImageView *imgView = [[UIImageView alloc] initWithFrame:CGRectMake(10, 10, 700, 700)];
imgView.image = Image;
imgView.frame = frame;
[imageSlider addSubview:imgView];
}
imageSlider.contentSize = CGSizeMake(imageSlider.frame.size.width*([myObject count]), 600);
imageSlider.delegate = self;
[self.view addSubview:imageSlider];
It starts from first image I dono how to start image from the selected image in previous viewController. Thanks in advance..
I have a UIScrollView and have images in that ScrollView and they are added programmatically. When I click on image, I want that image to be displayed on full screen.
What should I add to my code?
The number of images depend upon the [images count];
self.scrollView.contentSize = CGSizeMake(320, 134);
self.scrollView.delegate = self;
int X=0;
for (int i = 0; i < [images count]; i++)
{
UIImageView *imageView = [[UIImageView alloc] initWithFrame: CGRectMake(X, 0, 140, 136)] ;
imageView.backgroundColor = [UIColor redColor];
[imageView setImage: [UIImage imageNamed:[NSString stringWithFormat:#"%d.png", i]]];
[imageView setImage: [images objectAtIndex:i]];
[self.scrollView addSubview: imageView];
X = X + imageView.frame.size.height+5;
if(X > 320)
self.scrollView.contentSize = CGSizeMake(X, 134);
}
You should not add UIImageViews then.
Instead add UIButton of type Custom and add the Image to the Button and add an IBAction to the UIButtons which adds a FullScreenView with your image.
In your for() for each button add a tag with i and in your IBAction function get the tag with [sender tag] and get your image with [images objectAtIndex:[sender tag]]
Example:
-(void)test{
for (int i = 0; i < [images count]; i++)
{
UIButton *button = [UIButton buttonWithType:UIButtonTypeCustom];
button.frame = CGRectMake(X, 0, 140, 136);
[button setImage:[images objectAtIndex:i] forState:UIControlStateNormal];
button.tag = i;
[button addTarget:self action:#selector(showFullscreen:) forControlEvents:UIControlEventTouchUpInside];
[self.scrollView addSubview:button];
X = X + button.frame.size.height+5;
if(X > 320)
self.scrollView.contentSize = CGSizeMake(X, 134);
}
}
-(IBAction)showFullscreen:(id)sender{
UIImageView *imageView = [[UIImageView alloc] initWithFrame: CGRectMake(0, 0, 320, 480)] ;
imageView.backgroundColor = [UIColor redColor];
[imageView setImage: [images objectAtIndex:[sender tag]]];
[self.view addSubview: imageView];
}
Want to show UIButton done on UIScrollView for images. With the below code UIButton is showing but when I scroll UIImageViews, it shows only on very first imageview where as I want UIButton done should show on all image views in UIScrollView.
- (void)viewDidLoad
{
self.view.backgroundColor = [UIColor blackColor];
UIScrollView *imageScrollView = [[UIScrollView alloc] initWithFrame:CGRectMake(0, 0, self.view.frame.size.width, self.view.frame.size.height)];
UIButton *myButton = [UIButton buttonWithType:UIButtonTypeCustom];
[myButton addTarget:self action:#selector(dismissView:) forControlEvents:UIControlEventTouchUpInside];
myButton.frame = CGRectMake(0, 0, 60, 35);
[myButton.layer setMasksToBounds:YES];
[myButton.layer setCornerRadius:10.0f];
myButton.layer.borderWidth = 2;
myButton.layer.borderColor = [[UIColor whiteColor] CGColor];
[myButton setTitle:#"Done" forState:UIControlStateNormal];
myButton.backgroundColor = [UIColor blackColor];
UIBarButtonItem *button = [[UIBarButtonItem alloc] initWithCustomView:myButton];
[[self navigationItem] setRightBarButtonItem:button animated:YES];
imageScrollView.pagingEnabled = YES;
NSInteger numberOfViews = 61;
for (int i = 0; i < numberOfViews; i++) {
CGFloat xOrigin = i * self.view.frame.size.width;
NSString *imageName = [NSString stringWithFormat:#"image%d.png", i];
UIImage *image = [UIImage imageNamed:imageName];
UIImageView *imageView = [[UIImageView alloc] initWithImage:image];
imageView.frame = CGRectMake(xOrigin, 0, self.view.frame.size.width, self.view.frame.size.height);
[imageScrollView addSubview:imageView];
[imageScrollView addSubview:myButton];
[imageView release];
}
imageScrollView.contentSize = CGSizeMake(self.view.frame.size.width * numberOfViews, self.view.frame.size.height);
[self.view addSubview:imageScrollView];
[imageScrollView release];
}
How should I code it that UIButton Done should show on all image views when I scroll it.
Add your UIButton in for loop i.e. it can add each time when your new ImageView is add.
And change its x_Origin for each imageView -
- (void)viewDidLoad
{
[super viewDidLoad];
// Do any additional setup after loading the view, typically from a nib.
UIScrollView *imageScrollView = [[UIScrollView alloc] initWithFrame:CGRectMake(0, 0, self.view.frame.size.width, self.view.frame.size.height)];
imageScrollView.pagingEnabled = YES;
NSInteger numberOfViews = 61;
for (int i = 0; i < numberOfViews; i++)
{
CGFloat xOrigin = i * self.view.frame.size.width;
UIButton *myButton = [UIButton buttonWithType:UIButtonTypeCustom];
[myButton addTarget:self action:#selector(dismissView) forControlEvents:UIControlEventTouchUpInside];
myButton.frame = CGRectMake(xOrigin, 0, 60, 35);
[myButton setTitle:#"Done" forState:UIControlStateNormal];
myButton.backgroundColor = [UIColor blackColor];
[myButton.layer setMasksToBounds:YES];
[myButton.layer setCornerRadius:10.0f];
myButton.layer.borderWidth = 2;
myButton.layer.borderColor = [[UIColor whiteColor] CGColor];
NSString *imageName = [NSString stringWithFormat:#"image%d.png", i];
UIImage *image = [UIImage imageNamed:imageName];
UIImageView *imageView = [[UIImageView alloc] initWithImage:image];
imageView.frame = CGRectMake(xOrigin, 0, self.view.frame.size.width, self.view.frame.size.height);
[imageScrollView addSubview:imageView];
[imageScrollView addSubview:myButton];
}
imageScrollView.contentSize = CGSizeMake(self.view.frame.size.width * numberOfViews, self.view.frame.size.height);
[self.view addSubview:imageScrollView];
}
Remove these 2 lines
UIBarButtonItem *button = [[UIBarButtonItem alloc] initWithCustomView:myButton];
[[self navigationItem] setRightBarButtonItem:button animated:YES];
There is no need to do this. This means you're setting that button on rightBarButton of NavigationBar but in your case i think you dont want to do so.
Set frame for myButton in for loop similar to imageview frame.
myButton.frame= CGRectMake(xOrigin, 0, self.myButton.frame.size.width, self.myButton.frame.size.height);
I am trying to add uibutton inside the imageview.
But it was not displayed the button.
Even i tried adding it to the uiscrollview and also for self.view.
But nothing were displayed the uibutton
Pls let me know what is the problem

Based off your question, you'd like to add the UIButton as a subview to the UIImageView - I'm guessing in the for loop? Immediate problem I see is that the actual button is being generated outside of the for loop. I think your for loop is intended to look like this:
for (int i = 1; i <= myImagesCount; i++)
{
NSString *imageName = [NSString stringWithFormat:#"screen-%d.jpg", i];
UIImage *image = [UIImage imageNamed:imageName];
UIImageView *imageView = [[UIImageView alloc] initWithImage:image];
UIButton *button = [UIButton buttonWithType:UIButtonTypeRoundedRect];
[button addTarget:self action:#selector(buttonHandler) forControlEvents:UIControlEventAllEvents];
[button setTitle:#"point" forState:UIControlStateNormal];
button.frame = CGRectMake(0.0, 0.0, 100.0, 40.0);
button.backgroundColor = [UIColor blackColor];
CGRect rect = imageView.frame;
rect.size.height = myScrollView.frame.size.height;
NSLog(#"%d -----",self.view.frame.size.width);
rect.size.width = myScrollView.frame.size.width;
imageView.frame = rect;
imageView.tag = i;
[imageView addSubview:button];
[myScrollView addSubview:imageView];
[imageView release];
}
Try this
Declare button globally and set
[self layoutScrollImages];
[self.view bringSubViewToFront:button];
