I'm trying to add a UIButton in a cell which already has a UIImageView in the background.
I put this code in configureCell
UIButton *mail = [[UIButton alloc] initWithFrame:CGRectMake(10, 270, 40, 40)];
[mail setImage:[UIImage imageNamed:#"mail.png"] forState:UIControlStateNormal];
mail.backgroundColor = [UIColor whiteColor];
[mail addTarget:self action:#selector(sendMail) forControlEvents:UIControlEventTouchUpInside];
[cell.contentView addSubview:mail];
It works but the image in the UIButton is seems darker
I tried these but it didn't changed anything
mail.alpha = 1;
[cell.contentView bringSubviewToFront:mail];
Does anyone have an explanation for this, and a solution as well.
I had the same problem once and I solved it by setting the button's image for the UIControlStateHighlighted
[mail setImage:[UIImage imageNamed:#"mail.png"] forState:UIControlStateHighlighted];
Hope it works for you
Try this
UIButton *mail=[UIButton buttonWithType:UIButtonTypeCustom];
mail.frame= CGRectMake(10, 270, 40, 40);
[mail setImage:[UIImage imageNamed:#"mail.png"] forState:UIControlStateNormal];
mail.backgroundColor = [UIColor clearColor];
[mail addTarget:self action:#selector(sendMail) forControlEvents:UIControlEventTouchUpInside];
[cell.contentView addSubview:mail];

I'm currently trying to add a button to my app. If the user push on it, it should display an alert.
I want to add the button to a section header of a tableview. Here is my code in tableView:viewForHeaderInSection:
UIImageView *headerView = [[[UIImageView alloc] initWithFrame:CGRectMake(0, 0, tableView.bounds.size.width, 20)] autorelease];
...
UIButton *button = [UIButton buttonWithType:UIButtonTypeCustom];
[button setFrame:CGRectMake(180, 4, 15, 15)];
UIImage *img=[UIImage imageNamed:#"myimg"];
[button setImage:img forState:UIControlStateNormal];
[button addTarget:self action:#selector(showMyAlert) forControlEvents:UIControlEventTouchUpInside];
[headerView addSubview:button];
return headerView;
And in the same class, I have the method :
-(void)showMyAlert{
NSLog(#"HERE SHOW ALERT");
...
}
The button is correctly displayed but the showMyAlert method is never called when I push on it.
Does anyone have an idea of what is wrong with my code ?
Thanks if you could help me :)
Change your UIImageView as UIView and return it as the header view.
UIView *headerView = [[[UIView alloc] initWithFrame:CGRectMake(0, 0, tableView.bounds.size.width, 20)] autorelease];
Make sure img is not nil. If that is nil, your button will have no image and you will see nothing.
Modified below lines of code, Try like this:-
[button addTarget:self action:#selector(showMyAlert:) forControlEvents:UIControlEventTouchUpInside];
-(IBAction)showMyAlert:(id)sender{
NSLog(#"HERE SHOW ALERT");
...
}
Try this, in viewDidLoad,
-(void)viewDidLoad
{
UIView *headerView = [[UIView alloc] initWithFrame:CGRectMake(XXX, YYY, XXX, YYY)];
UIImageView *imageView = [[[UIImageView alloc] initWithFrame:CGRectMake(0, 0, tableView.bounds.size.width, 20)] autorelease];
[headerView addSubview:imageView];
UIButton *button = [UIButton buttonWithType:UIButtonTypeCustom];
[button setFrame:CGRectMake(180, 4, 15, 15)];
UIImage *img=[UIImage imageNamed:#"myimg"];
[button setImage:img forState:UIControlStateNormal];
[button addTarget:self action:#selector(showMyAlert) forControlEvents:UIControlEventTouchUpInside];
[headerView addSubview:button];
self.tableView.tableHeaderView = headerView;
}
If I change it to be a subview of timerView it works fine but nothing else works.
timerView = [[UIView alloc] initWithFrame:CGRectMake(0, 278, 105, 33)];
[self.view addSubview:timerView];
UIImageView *changerBackground = [[UIImageView alloc] init];
[changerBackground setImage:[UIImage imageNamed:#"speedbackground.png"]];
changerBackground.frame = CGRectMake(-12 , -16, 105, 33);
[timerView addSubview:changerBackground];
UIButton *normal = [UIButton buttonWithType:UIButtonTypeCustom];
normal.frame = CGRectMake(40, 8, 22, 22);
[normal setBackgroundImage:[UIImage imageNamed:#"normalwhite.png"] forState:UIControlStateNormal];
[normal setBackgroundImage:[UIImage imageNamed:#"normalred.png"] forState:UIControlStateHighlighted];
[normal addTarget:self action:#selector(quickTest:) forControlEvents:UIControlEventTouchUpInside];
[changerBackground addSubview:normal];
[changerBackground setUserInteractionEnabled:YES];
will solve your issue. As the UIImageView disables the user interaction by default.
I want to add two buttons to a subview that appears over the parent view when the view will appear. The buttons are initialized correctly and appear but they don´t react when pressed. Does anybody know why? Here is my code:
-(void) viewWillAppear:(BOOL)animated{
[super viewWillAppear:animated];
self.view.backgroundColor = [UIColor blackColor];
//Animation View
imageView= [[UIImageView alloc] initWithFrame:CGRectMake(0, 499, 320, 0)];
imageView.image = [UIImage imageNamed:#"trans.png"];
[imageView setClipsToBounds:YES];
[imageView setContentMode:UIViewContentModeBottom];
[self.view addSubview:imageView];
[UIView animateWithDuration:1.0f
delay:0.5f
options:UIViewAnimationOptionCurveEaseOut
animations:^(void) {
imageView.frame = CGRectMake(0, 92, 320, 320);
}
completion:NULL];
[self.view bringSubviewToFront:imageView];
// Animation View Buttons
//1 Amazon
UIButton *button1 = [UIButton buttonWithType:UIButtonTypeCustom];
UIImage *button=[UIImage imageNamed:#"button.png"];
[button1 setImage:button forState:UIControlStateNormal];
button1.frame = CGRectMake(0, 290, 80, 30);
button1.backgroundColor=[UIColor whiteColor];
button1.showsTouchWhenHighlighted=YES;
[button1 addTarget:self
action:#selector(openAmazon:)
forControlEvents:UIControlEventTouchUpInside];
[imageView addSubview:button1];
//2 iTunes
UIButton *button2 = [UIButton buttonWithType:UIButtonTypeCustom];
[button2 setImage:button forState:UIControlStateNormal];
button2.frame = CGRectMake(82, 290, 80, 30);
button2.backgroundColor=[UIColor whiteColor];
button2.showsTouchWhenHighlighted=YES;
[button2 addTarget:self
action:#selector(openiTunes:)
forControlEvents:UIControlEventTouchUpInside];
[imageView addSubview:button2];
}
you need to use the option UIViewAnimationOptionAllowUserInteraction
...
options:UIViewAnimationOptionCurveEaseOut | UIViewAnimationOptionAllowUserInteraction
...
Make sure you set the userInteractionEnabled property on the imageView:
[imageView setUserInteractionEnabled:YES];
[self.view bringSubviewToFront:imageView];
you are bringing your image view to the front after increasing its frame, this is blocking the buttons actions
I have a UIBarButtonItem that I want hugging the very left of the screen. I've tried putting a fixed barbutton with width=0 before the button and other configurations but there's always several pixels between the button and x=0.
I've also tried changing the imageInset of the UIButton
UIButton *moreButton = [UIButton buttonWithType:UIButtonTypeCustom];
moreButton.frame = CGRectMake(0, 0, 60, 35);
[moreButton setImage:[UIImage imageNamed:#"Morebutton"] forState:UIControlStateNormal];
moreButton.imageEdgeInsets = UIEdgeInsetsMake(0, -8, 0, 8);
[moreButton addTarget:self action:#selector(pressedMoreButton:) forControlEvents:UIControlEventTouchUpInside];
UIBarButtonItem *moreBar = [[[UIBarButtonItem alloc] initWithCustomView:moreButton] autorelease];
But tapping near the edge of the screen doesn't trigger the selector (probably because only the image is moved but not the button itself) and increasing the size of the button doesn't affect the gap between the button and the left side.
Thanks
try to put your button to the container view and change position of button on the view.
UIButton *button = [UIButton buttonWithType:UIButtonTypeCustom];
[button setBackgroundImage:buttonImage forState:UIControlStateNormal];
button.contentMode = UIViewContentModeScaleAspectFit;
button.frame= CGRectMake(-4.0, 0.0, 30, 30);
[button addTarget:target action:action forControlEvents:UIControlEventTouchUpInside];
UIView *v=[[[UIView alloc] initWithFrame:CGRectMake(0.0, 0.0, cellTextSize.width+10, buttonImage.size.height)] autorelease];
v.backgroundColor = [UIColor clearColor];
[v addSubview:button];
return [[[UIBarButtonItem alloc] initWithCustomView:v] autorelease];
I want to create a UIButton that uses its setBackgroundImage, setImage, and setTitle properties, but when I add setTitle in combination with setImage and setBackgroundImage the title doesn't appear.
I've tried the following.
[button setBackgroundImage:[UIImage imageNamed:#"image3.jpg"] forState:UIControlStateNormal];
[button setImage:[UIImage imageNamed:#"month_pct_general.png"] forState:UIControlStateNormal];
[button setTitle:[NSString stringWithFormat:#"%d",[button tag]] forState:UIControlStateNormal];
[button setTitleColor:[UIColor whiteColor] forState:UIControlStateNormal];
[button.titleLabel setFont:[UIFont boldSystemFontOfSize:20.0f]];
[button setTitleEdgeInsets:UIEdgeInsetsMake(45, 0, 0, 25)];
your title on button and on title your all image it there so add label on the image like this.
UIButton *myButton = [[UIButton buttonWithType:UIButtonTypeCustom] retain];
[myButton setFrame:CGRectMake(0,3,70,32)];
[myButton setImage:[UIImage imageNamed:#"image.png"] forState:UIControlStateNormal];
[myButton addTarget:self action:#selector(compete) forControlEvents:UIControlEventTouchUpInside];
UILabel *Label=[[UILabel alloc]initWithFrame:CGRectMake(6, 5, 60, 20)];
[Label setText:#"label"];
Label.backgroundColor=[UIColor clearColor];
[Label setFont:[UIFont fontWithName:#"Helvetica-Bold" size:12]];
Label.textColor=[UIColor whiteColor];
[myButton addSubview:Label];
your all image above the title only so your title is in background so use label on image view.
If you are making GUI using interface builder, then click on the label and go to Editor-> Arrange -> Send to Front.
