Hi I have a UIButton that I created programmatically but unfortunately its not working. When I click on the UIButton nothing happens. I don't know what is the problem. Any help would be appreciated.
UIButton *connectedStories = [UIButton buttonWithType:UIButtonTypeRoundedRect];
//set the position of the button
connectedStories.frame = CGRectMake(10, 10, 1900, 30);
connectedStories.backgroundColor = [UIColor whiteColor];
[connectedStories setTitle:#"Button" forState:UIControlStateNormal];
[connectedStories setTitleColor:[UIColor blackColor] forState:UIControlStateNormal];
[connectedStories addTarget:self action:#selector(buttonClicked) forControlEvents:UIControlEventTouchUpInside];
[label setText:storyTitle];
[label1 setText:storyDescription];
[contentView addSubview:backGroundImageView];
[contentView addSubview:connectedStories];
[contentView addSubview:label];
[contentView addSubview:label1];
[viewContainer addSubview:contentView];
return contentView;
- (void)buttonClicked
{
NSLog(#"button clicked");
}
I think labels recives touches instead of button.
Add userInteractionEnabled = NO; to your labels.
label.userInteractionEnabled = NO;
label1.userInteractionEnabled = NO;
Try changing the top part of your code to this:
CGRect frame = CGRectMake(10, 10, 1900, 30);
UIButton *connectedStories = [[UIButton alloc] initWithFrame:frame];
//set the position of the button
[connectedStories setBackgroundColor:[UIColor whiteColor]];
[connectedStories setTitle:#"Button" forState:UIControlStateNormal];
[connectedStories setTitleColor:[UIColor blackColor] forState:UIControlStateNormal];
[connectedStories addTarget:nil action:#selector(buttonClicked) forControlEvents:UIControlEventTouchUpInside];
It may very well be the following:
[contentView addSubview:backGroundImageView];
[contentView addSubview:connectedStories];
[contentView addSubview:label];
[contentView addSubview:label1];
im sure you would need to add them in the following order:
[contentView addSubview:backGroundImageView];
[contentView addSubview:label];
[contentView addSubview:label1];
[contentView addSubview:connectedStories];
This is because when you call addSubview: it adds it to end of the receivers list of subViews and the most recent subView appears on top.
Check out the UIView Documentation here
the reason that the Interaction isn't being detected is that you are not passing the touchEvents through to the other subViews as they are being captured by label1 and stopping there.
By default the last subView captures all touch events and doesn't pass them on.
Add the colon in last of your method in selector
[connectedStories addTarget:self action:#selector(buttonClicked:) forControlEvents:UIControlEventTouchUpInside];
[label setText:storyTitle];
UIButton *custombutton = [UIButton buttonWithType:UIButtonTypeRoundedRect];
[custombutton addTarget:self
action:#selector(aMethod:)
forControlEvents:UIControlEventTouchUpInside];
[custombutton setTitle:#"Click" forState:UIControlStateNormal];
custombutton.frame = CGRectMake(80.0, 110.0, 160.0, 40.0);
custombutton.titleLabel.textColor = [UIColor colorWithRed: 2.0f/255.0f green: 155.0f/255.0f blue: 213.0f/255.0f alpha:1];
[custombutton setImage:[UIImage imageNamed:#"hh.png"] forState:UIControlStateNormal];
[view addSubview:custombutton];

I had an application in which i am setting the content size of the scroll view dynamically according to the number of buttons which i am creating from an array.like this `
for(int i =0;i<[sarray count];i++)
{
NSMutableDictionary *dicttable=[sarray objectAtIndex:i];
NSString *head=[dicttable objectForKey:#"cat"];
btn= [UIButton buttonWithType:UIButtonTypeCustom];
int j=i+1;
btn.frame = CGRectMake((j-1)*87,0,87, 44);
[btn setBackgroundImage:[UIImage imageNamed:#"bar.png"] forState:UIControlStateNormal];
[btn setBackgroundImage:[UIImage imageNamed:#"bar_hvr.png"] forState:UIControlStateSelected];
btn.backgroundColor = [UIColor clearColor];
btn.titleLabel.font = [UIFont fontWithName:#"Helvetica-Bold" size:14];
btn.titleLabel.textColor = [UIColor whiteColor];
[btn setTitle:head forState:UIControlStateNormal];
btn.tag = i;
[btn setShowsTouchWhenHighlighted:YES];
[Scroller addSubview:btn];
[btn addTarget:self action:#selector(buttonTapped:) forControlEvents:UIControlEventTouchUpInside];
if(btn.tag==0)
{
sendActionsForControlEvents:UIControlEventTouchUpInside];
}
else
{
btn.selected=NO;
}
}
}
[Scroller setContentSize:CGSizeMake([sarray count]*85, 44)];
`
but here the problem is after the last button also the scroll view scrolls .it need not to be happend,i need the scrolling ends with last button on the view,can anybody help me on this
set scrollview bounces to NO
scrollView.bounces = NO;
yes as you said it looses the smoothness. But no other choice. If you found any sol please update the answer.
hey i am sending you complete example to make button dynamicay and seting the content size scrollview on number of count ,i had just given u one example code u have to set the size of frame of button as u requried
UIScrollView *scroll_View=[[UIScrollView alloc]initWithFrame:self.view.bounds];
[self.view addSubview:scroll_View];
int y=0;
for(int i =1;i<10;i++)
{
// NSMutableDictionary *dicttable=[sarray objectAtIndex:i];
// NSString *head=[dicttable objectForKey:#"cat"];
UIButton* btn= [UIButton buttonWithType:UIButtonTypeRoundedRect];
btn.frame = CGRectMake(y,89,100, 50);
[btn setBackgroundImage:[UIImage imageNamed:#"bar.png"] forState:UIControlStateNormal];
[btn setBackgroundImage:[UIImage imageNamed:#"bar_hvr.png"] forState:UIControlStateSelected];
btn.backgroundColor = [UIColor clearColor];
btn.titleLabel.font = [UIFont fontWithName:#"Helvetica-Bold" size:14];
NSString *str=[NSString stringWithFormat:#"%d",i];
btn.titleLabel.textColor = [UIColor whiteColor];
[btn setTitle:str forState:UIControlStateNormal];
btn.tag = i;
[btn setShowsTouchWhenHighlighted:YES];
[scroll_View addSubview:btn];
[btn addTarget:self action:#selector(buttonTapped:) forControlEvents:UIControlEventTouchUpInside];
y=110*i;
}
[scroll_View setContentSize:CGSizeMake(y, 400)];
enjoy coding
You just declare one yMargin variable of type CGFloat and initialize it with some required value as 0. Now every time whenever you are adding a new subview vertically do y+=lbl.frame.size.height;
Now setContentSize:CGSizeMake([sarray count]*85, y margin+someRequiredMargin)];
(someRequiredMargin - you want to add below )
I want to display two buttons inside the popoverview. I am using WEPOPOVER, I am able to display one btn.
But I am not sure how to display the two buttons.
UIButton *editBtn = [UIButton buttonWithType:UIButtonTypeCustom];
[editBtn setTitle:#"EDIT ME" forState:UIControlStateNormal];
[editBtn setFrame:CGRectMake(250, 0, 100,40)];
[editBtn addTarget:self action:#selector() forControlEvents:UIControlEventTouchUpInside];
[editBtn setTitleColor:[UIColor whiteColor] forState:UIControlStateNormal];
editBtn.titleLabel.shadowOffset = CGSizeMake(0, -1);
editBtn.titleLabel.font = [UIFont boldSystemFontOfSize:20];
editBtn.backgroundColor = [UIColor blackColor];
UIButton *deleteBtn = [UIButton buttonWithType:UIButtonTypeCustom];
[deleteBtn setTitle:#"Delete ME" forState:UIControlStateNormal];
[deleteBtn setFrame:CGRectMake(250, 0, 100,40)];
[deleteBtn addTarget:self action:#selector(doSubscription) forControlEvents:UIControlEventTouchUpInside];
[deleteBtn setTitleColor:[UIColor whiteColor] forState:UIControlStateNormal];
deleteBtn.titleLabel.shadowOffset = CGSizeMake(0, -1);
deleteBtn.titleLabel.font = [UIFont boldSystemFontOfSize:20];
deleteBtn.backgroundColor = [UIColor blackColor];
// place inside a temporary view controller and add to popover
UIViewController *viewCon = [[UIViewController alloc] init];
viewCon.view = (UIView *)[NSArray arrayWithObjects:editBtn,deleteBtn, nil];
viewCon.contentSizeForViewInPopover = editBtn.frame.size; // Set the content size
navPopover = [[WEPopoverController alloc] initWithContentViewController:viewCon];
[navPopover presentPopoverFromRect:editButton.frame
inView:self.view
permittedArrowDirections:UIPopoverArrowDirectionUp | UIPopoverArrowDirectionDown
animated:YES];
You have given the same frame for both buttons. So it shows just one button.
[editBtn setFrame:CGRectMake(250, 0, 100,40)];
[deleteBtn setFrame:CGRectMake(250, 0, 100,40)];
I am write code for scrollview and add button on it but button not appear in scrollview.
My code
tableProductScrollView=[[UIScrollView alloc]initWithFrame:CGRectMake(75, 442, 874, 208)];
tableProductScrollView.delegate=self;
[tableProductScrollView setBackgroundColor:[UIColor clearColor]];
[tableProductScrollView setCanCancelContentTouches:YES];
tableProductScrollView .indicatorStyle = UIScrollViewIndicatorStyleBlack;
tableProductScrollView .pagingEnabled = YES;
tableProductScrollView.showsVerticalScrollIndicator = YES;
[tableProductScrollView setContentSize:CGSizeMake(1748,208)];
[tableProductScrollView setScrollEnabled:YES];
[self.view addSubview:tableProductScrollView];
CGRect frameProduct1 = CGRectMake(85, 445, 142, 150);
tableProduct1Button = [UIButton buttonWithType:UIButtonTypeCustom];
tableProduct1Button.frame = frameProduct1;
UIImage *imgProduct1= [UIImage imageNamed:#"product6-small.png"];
[tableProduct1Button setImage:imgProduct1 forState:UIControlStateNormal];
tableProduct1Button.backgroundColor = [UIColor clearColor];
tableProduct1Button.highlighted = YES;
//---add the action handler and set current class as target---
[tableProduct1Button addTarget:self
action:#selector(homeButtonAction)
forControlEvents:UIControlEventTouchUpInside];
[tableProductScrollView addSubview: tableProduct1Button];
please give me suggestion.
maybe:
UIButton *tableProduct1Button =
[UIButton
buttonWithType:UIButtonTypeCustom];
Try to make a round rect button with some color and then see if you are able to see the button or else check the frame. Or try to set an image for the highlighted state.
[tableProduct1Button setImage:image1 forState:UIControlStateHighlighted];
I have a subview that has been added to my UIView. The idea is that the subview is a hovering panel with uibuttons. The subview is given an alpha of 0.2, as the user needs to be able to see what is behind it.
The problem is that when I add uibuttons to the subview, they inherit the alpha from the subview (I want the buttons to be non-transparent and have an alpha of 1.0). I've tried to tackle this problem by iterating through the uibuttons and setting their alpha back to 1.0 without success. Solutions?
// Create the subview and add it to the view
topHoverView = [[UIView alloc] initWithFrame:CGRectMake(0, 0, 320, 50)];
topHoverView.backgroundColor = [UIColor blackColor];
[topHoverView setAlpha:0.2];
[self.view addSubview:topHoverView];
// Add button 1
button1 = [UIButton buttonWithType:UIButtonTypeRoundedRect];
[button1 setFrame:CGRectMake(20, 10, 80, 30)];
[button1 setTitle:#"New" forState:UIControlStateNormal];
[button1 addTarget:self action:#selector(button1Action:) forControlEvents:UIControlEventTouchUpInside];
[topHoverView addSubview:button1];
// Add button 2
button2 = [UIButton buttonWithType:UIButtonTypeRoundedRect];
[button2 setFrame:CGRectMake(120, 10, 80, 30)];
[button2 setTitle:#"Clear" forState:UIControlStateNormal];
[button2 addTarget:self action:#selector(button2Action:) forControlEvents:UIControlEventTouchUpInside];
[topHoverView addSubview:button2];
// Add button 3
button3 = [UIButton buttonWithType:UIButtonTypeRoundedRect];
[button3 setFrame:CGRectMake(220, 10, 80, 30)];
[button3 setTitle:#"Delete" forState:UIControlStateNormal];
[button3 addTarget:self action:#selector(button3Action:) forControlEvents:UIControlEventTouchUpInside];
[topHoverView addSubview:d button3];
// Attempt to iterate through the subviews (buttons) to set their transparency back to 1.0
for (UIView *subView in topHoverView.subviews) {
subView.alpha = 1.0;
}
You should create topHoverView with alpha 1.0 and a transparent background color. Then add a subview with a black background that covers the complete view with alpha 0.2 and then add the buttons to topHoverView:
// Create the subview and add it to the view
topHoverView = [[UIView alloc] initWithFrame:CGRectMake(0, 0, 320, 50)];
topHoverView.backgroundColor = [UIColor transparentColor];
[topHoverView setAlpha:1.0];
[self.view addSubview:topHoverView];
canvasView = [[UIView alloc] initWithFrame:CGRectMake(0, 0, 320, 50)];
canvasView.backgroundColor = [UIColor blackColor];
[canvasViewView setAlpha:0.2];
[topHoverView.view addSubview:canvasView];
// Add button 1
button1 = [UIButton buttonWithType:UIButtonTypeRoundedRect];
[button1 setFrame:CGRectMake(20, 10, 80, 30)];
[button1 setTitle:#"New" forState:UIControlStateNormal];
[button1 addTarget:self action:#selector(button1Action:) forControlEvents:UIControlEventTouchUpInside];
[topHoverView addSubview:button1];
// Add button 2
button2 = [UIButton buttonWithType:UIButtonTypeRoundedRect];
[button2 setFrame:CGRectMake(120, 10, 80, 30)];
[button2 setTitle:#"Clear" forState:UIControlStateNormal];
[button2 addTarget:self action:#selector(button2Action:) forControlEvents:UIControlEventTouchUpInside];
[topHoverView addSubview:button2];
// Add button 3
button3 = [UIButton buttonWithType:UIButtonTypeRoundedRect];
[button3 setFrame:CGRectMake(220, 10, 80, 30)];
[button3 setTitle:#"Delete" forState:UIControlStateNormal];
[button3 addTarget:self action:#selector(button3Action:) forControlEvents:UIControlEventTouchUpInside];
[topHoverView addSubview:d button3];
// Attempt to iterate through the subviews (buttons) to set their transparency back to 1.0
for (UIView *subView in topHoverView.subviews) {
subView.alpha = 1.0;
}
Instead of
topHoverView.backgroundColor = [UIColor transparentColor];
, the following code is right.
topHoverView.backgroundColor = [UIColor clearColor];
I'm trying to set the shadow colour on a UIButton, but all I seem to be able to get is a mid grey.
UIButton *button = [UIButton buttonWithType:UIButtonTypeRoundedRect];
button.frame = CGRectMake(20, 20, 200, 100);
[button setTitle:#"a" forState:UIControlStateNormal];
[button addTarget:self
action:#selector(buttonPressed:)
forControlEvents:UIControlEventTouchUpInside];
[button setTitleColor:[UIColor blackColor] forState:UIControlStateNormal];
[button.titleLabel setFont:[UIFont fontWithName:#"Helvetica" size:96]];
// set up the button colours
button.titleLabel.shadowColor = [UIColor blueColor];
[button.titleLabel setShadowOffset:CGSizeMake(5.0f, 5.0f)];
[self.view addSubview:button];

Am I setting the wrong property, or is it the way that I'm setting shadowColor that's wrong?
Thanks.
Have you tried:
[button setTitleShadowColor:[UIColor blueColor] forState:UIControlStateNormal];
