I have this code:
if([self.popoverController isPopoverVisible])
{
[self.popoverController dismissPopoverAnimated:YES];
return;
}
UIViewController* popoverContent = [[UIViewController alloc]init];
popoverContent.view = tableView1.view;
self.popoverController = [[UIPopoverController alloc]
initWithContentViewController:popoverContent];
[self.popoverController presentPopoverFromRect:CGRectMake(1200, 280, 50, 50) inView:self.view permittedArrowDirections:UIPopoverArrowDirectionDown animated:TRUE];
[[[popoverController contentViewController] view] setAlpha:1]; //alpha del contenuto del popover
[popoverContent release];
It work fine, but I'm not able to place the popover in the lower right, I try to change values in
[self.popoverController presentPopoverFromRect:CGRectMake(1200, 550, 100, 100) inView:self.view permittedArrowDirections:UIPopoverArrowDirectionDown animated:TRUE];
but I want this popover small in lower right...how can I do?
I solved in this way:
[popoverController setPopoverContentSize:CGSizeMake(320.0f, 262.0f)];
[self.popoverController presentPopoverFromBarButtonItem:barButton permittedArrowDirections:UIPopoverArrowDirectionAny animated:YES];

I am trying to call a method to ViewController class form AppDelegate, it enter to the method but the problem is that is not displaying anything , I was looking for, but I can´t find the answer. Some one could help me? thanks
this is the code :

if (mainDelegate.isflagON=TRUE)
{

{
[super viewDidLoad];
AppDelegate *mainDelegate = [[UIApplication sharedApplication] delegate];
if (mainDelegate.isflagON==false)
{
mainDelegate.isflagON=true;
CGSize viewSize = self.view.bounds.size;
// Add this line
GameScene *scene = [[GameScene alloc] initWithSize:viewSize];
scene.scaleMode = SKSceneScaleModeAspectFill;
self.scene = scene;
// Configure the view.
skView = (SKView *)self.view;
skView.showsFPS = YES;
skView.showsNodeCount = YES;
// Present the scene.
[skView presentScene:scene];
}else
{
[self doPause];
}
}
-(void) imprime
{
[self doPause];
}
- (void)doPause {
CGRect myImageRect = CGRectMake(0.0f, 0.0f, 200.0f, 200.0f);
backImageView = [[UIImageView alloc] initWithFrame:myImageRect];
[backImageView setImage:[UIImage imageNamed:#"dialogBox.png"]];
[self.view addSubview:backImageView];
[self.view sendSubviewToBack:backImageView];
//set the position of the button
buttonContinuar = [UIButton buttonWithType:UIButtonTypeCustom];
[buttonContinuar setBackgroundImage:[UIImage imageNamed:#"dialogButton.png"]
forState:UIControlStateNormal];
buttonContinuar.frame = CGRectMake(40.0f, 50.0f, 120, 35);
[buttonContinuar addTarget:self action:#selector(buttonWasClicked:) forControlEvents:UIControlEventTouchUpInside];
[buttonContinuar setTitle:#"Continuar" forState:UIControlStateNormal];
//add the button to the view
[self.view addSubview:buttonContinuar];
buttonMapa = [UIButton buttonWithType:UIButtonTypeCustom];
//[button setTitle:#"Continuar" forState:UIControlStateNormal];
[buttonMapa setBackgroundImage:[UIImage imageNamed:#"dialogButton.png"]
forState:UIControlStateNormal];
buttonMapa.frame = CGRectMake(40.0f, 85.0f, 120, 35);
[buttonMapa addTarget:self action:#selector(buttonMapaClicked:) forControlEvents:UIControlEventTouchUpInside];
[buttonMapa setTitle:#"Mapa" forState:UIControlStateNormal];
//add the button to the view
[self.view addSubview:buttonMapa];
buttonMenu = [UIButton buttonWithType:UIButtonTypeCustom];
//[button setTitle:#"Continuar" forState:UIControlStateNormal];
[buttonMenu setBackgroundImage:[UIImage imageNamed:#"dialogButton.png"]
forState:UIControlStateNormal];
buttonMenu.frame = CGRectMake(40.0f, 120.0f, 120, 35);
[buttonMenu addTarget:self action:#selector(buttonMenuClicked:) forControlEvents:UIControlEventTouchUpInside];
[buttonMenu setTitle:#"Menu" forState:UIControlStateNormal];
//add the button to the view
[self.view addSubview:buttonMenu];
}
You can try this
- (void)applicationWillEnterForeground:(UIApplication *)application
{
if (mainDelegate.isflagON=TRUE)
{
ViewController *vc=[[ViewController alloc]init];
[vc pause];
}
}
I have a source code where the main screen has 10 buttons (images buttons), each button is linked to sql database with tableview items, in the XIB I select which tag for each button, 1, 2, 3, 4..
I want make these buttons to scroll, how to do so?
I tried to convert the view into scrollview, then I have deleted the images, and created buttons in the scrollview, but now I do not know how to link each of the button to its tag in the tableview?
below is what I used:
#implementation mainViewController;
#synthesize master;
#synthesize model;
(void)viewWillAppear:(BOOL)animated{
UIScrollView *scrollview=[[UIScrollView alloc]initWithFrame:CGRectMake(0,0,320,480)];
scrollview.showsVerticalScrollIndicator=YES;
scrollview.scrollEnabled=YES;
scrollview.userInteractionEnabled=YES;
[self.view addSubview:scrollview];
scrollview.contentSize = CGSizeMake(320,960);//You Can Edit this with your require
scrollview.pagingEnabled=YES;
UIButton *button = [UIButton buttonWithType:UIButtonTypeRoundedRect];
[button addTarget:self action:#selector(aMethod:) forControlEvents:UIControlEventTouchDown];
[button setTitle:#"Show View" forState:UIControlStateNormal];
button.frame = CGRectMake(80.0, 210.0, 160.0, 40.0);
UIImageView* imageview1 =[[UIImageView alloc] initWithImage:[UIImage imageNamed:#"c1#2x.png"]];
imageview1.frame=CGRectMake(18.0, 18, 285,50);
[scrollview addSubview:imageview1];
UIImageView* imageview2 =[[UIImageView alloc] initWithImage:[UIImage imageNamed:#"c2#2x.png"]];
imageview2.frame=CGRectMake(18.0, 78, 285,50);
[scrollview addSubview:imageview2];
UIImageView* imageview3 =[[UIImageView alloc] initWithImage:[UIImage imageNamed:#"c3#2x.png"]];
imageview3.frame=CGRectMake(18.0, 138, 285,50);
[scrollview addSubview:imageview3];
UIImageView* imageview4 =[[UIImageView alloc] initWithImage:[UIImage imageNamed:#"c4#2x.png"]];
imageview4.frame=CGRectMake(18.0, 198, 285,50);
[scrollview addSubview:imageview4];
Assingn a tag to the button when you create it:
[buttonName setTag:1];
[buttonName addTarget:self action:#selector(aMethod:) forControlEvents:UIControlEventTouchDown];
Then use:
-(void)aMethod:(UIButton *)button {
if ([button tag] == 1) {
...do something...
}
}
Hope this helps.
I am tyring to add UISegmentedControl to UIScrolview programmatically.
I am using below code..
I don't why the scrollview is not enabled.
UIScrollView *scroll = [[UIScrollView alloc] initWithFrame:CGRectMake(0, 0, 320, 435)];
scroll.contentSize = CGSizeMake(320, 700);
scroll.showsHorizontalScrollIndicator = YES;
NSArray *menu = [NSArray arrayWithObjects:[UIImage imageNamed:#"Accountimg.png"],[UIImage imageNamed:#"Challengesimg.png"],[UIImage imageNamed:#"Profileimg.png"],[UIImage imageNamed:#"Challengesimg.png"],nil];
UISegmentedControl *menuSegmentedControl = [[UISegmentedControl alloc] initWithItems:menu];
menuSegmentedControl.frame = CGRectMake(0,0,450,40);
menuSegmentedControl.segmentedControlStyle = UISegmentedControlStyleBar;
[scroll addSubview:menuSegmentedControl];
[menuScrollView addSubview:scroll];
[menuSegmentedControl release];
[scroll release];
I am unable to scroll horizontally..
Thanks in advance
UPDATE:
I am able to get the horizontal scroll.
Code updated:
menuSegmentedControl.frame = CGRectMake(0,0,500,35);
menuSegmentedControl.segmentedControlStyle = UISegmentedControlStyleBar;
menuScrollView.contentSize = CGSizeMake(menuSegmentedControl.frame.size.width, menuSegmentedControl.frame.size.height);
menuScrollView.showsVerticalScrollIndicator = NO;
[menuScrollView addSubview:menuSegmentedControl];
menuScrollView.clipsToBounds = YES;
Thank you.
hi iam trying to put a uisegmented controls over a uiscrollview beacuse i want them to scroll horizontally this is the code i tried
UIScrollView *scroll = [[UIScrollView alloc] initWithFrame:CGRectMake(0, 0, 600, 300)];
scroll.contentSize = CGSizeMake(500, 50);
scroll.showsHorizontalScrollIndicator = YES;
scroll.pagingEnabled = YES;
scroll.showsHorizontalScrollIndicator = YES;
scroll.autoresizingMask = YES;
scroll.autoresizesSubviews = YES;
NSArray *itemArray = [NSArray arrayWithObjects: #"One", #"Two", #"Three",#"four",#"Five", nil];
UISegmentedControl *segmentedControl = [[UISegmentedControl alloc] initWithItems:itemArray];
segmentedControl.frame = CGRectMake(0,10, 500, 50);
segmentedControl.segmentedControlStyle = UISegmentedControlStylePlain;
segmentedControl.selectedSegmentIndex = 4;
[scroll addSubview:segmentedControl];
[self.view addSubview:scroll];
any one please help me to accomplish this . thanks in advance happy coding
The frame for the scroll View must be less than the Content size of scroll view. If you will increase your content size definitely it will work. For example:-
UIScrollView *scroll = [[UIScrollView alloc] initWithFrame:CGRectMake(0, 0, 320, 50)];
scroll.contentSize = CGSizeMake(500, 50);
scroll.showsHorizontalScrollIndicator = YES;
scroll.pagingEnabled = YES;
scroll.showsHorizontalScrollIndicator = YES;
scroll.autoresizingMask = YES;
scroll.autoresizesSubviews = YES;
NSArray *itemArray = [NSArray arrayWithObjects: #"One", #"Two", #"Three",#"four",#"Five", nil];
UISegmentedControl *segmentedControl = [[UISegmentedControl alloc] initWithItems:itemArray];
segmentedControl.frame = CGRectMake(0,10, 500, 50);
segmentedControl.segmentedControlStyle = UISegmentedControlStylePlain;
segmentedControl.selectedSegmentIndex = 4;
[scroll addSubview:segmentedControl];
[self.view addSubview:scroll];
If its supportive please mark the answer correct. Thanks very much.
I'm trying to make a view looking almost like the info-view in appStore, with text on the first half of the view and images on the second half. I've tried to use a scrollview in another scrollview. The first view (containing a textview on the top half and a scrollview on the bottom half) scrolls nice, but the scrollview at the bottom (containing several imageviews) doesn't scroll.
Any ideas how to make the second scrollview to scroll?
scrollView is the view containing a textview and a scrollview.
imageScrollView is the view with the imageviews.
[scrollView setContentSize:CGSizeMake(320, 585)];
[imageScrollView setContentSize:CGSizeMake(1520, 400)];
I recently figured it out myself, but forgot to post the answer. The problem was that I set the sizes of the scrollviews in .xib to the same sizes as in the code. When I changed it to 320,416 and 320,400 I was able to scroll them with the setContentSize. In the imageScrollView I then added images along the x-axis (first image at 0, second at image width + a small space and so on). Hope this could help someone.
