Currently I made a back Label for background and add UIButton on UILabel. It's showing in iOS 7 but in iOS 8 it's not showing . If I replace UILabel with UIView then It's working fine.
If I use UILabel in iOS 8 using this code For showing UILabel and subview UIButton
UILabel *downLabel = [[UILabel alloc]init];
downLabel.frame = CGRectMake(0, SCREEN_HEIGHT*0.92, SCREEN_WIDTH,SCREEN_HEIGHT*0.08 );
[downLabel setBackgroundColor:[UIColor colorWithRed:(66/255.f) green:(67/255.f) blue:(63/255.f) alpha:1]];
downLabel.userInteractionEnabled = YES;
[self.view addSubview:downLabel];
UIButton *downbtnobj = [[UIButton alloc]initWithFrame:CGRectMake(SCREEN_WIDTH*0.68,downLabel.frame.size.height/10,SCREEN_WIDTH*0.30,downLabel.frame.size.height/1.25)];
UIImage *btndownImage = [UIImage imageNamed:#"img 3.png"];
[downbtnobj setImage:btndownImage forState:UIControlStateNormal];
[downbtnobj addTarget:self action:#selector(bulletInButtonClicked) forControlEvents:UIControlEventTouchUpInside];
[downLabel addSubview:downbtnobj];
Now You can see only UILabel is showing but button is not showing on UILabel.
One another this If I replace UILabel by UIView then It's showing perfect.
UIView *downLabel = [[UIView alloc]init];
downLabel.frame = CGRectMake(0, SCREEN_HEIGHT*0.92, SCREEN_WIDTH,SCREEN_HEIGHT*0.08 );
[downLabel setBackgroundColor:[UIColor colorWithRed:(66/255.f) green:(67/255.f) blue:(63/255.f) alpha:1]];
downLabel.userInteractionEnabled = YES;
[self.view addSubview:downLabel];
UIButton *downbtnobj = [[UIButton alloc]initWithFrame:CGRectMake(SCREEN_WIDTH*0.68,downLabel.frame.size.height/10,SCREEN_WIDTH*0.30,downLabel.frame.size.height/1.25)];
UIImage *btndownImage = [UIImage imageNamed:#"img 3.png"];
[downbtnobj setImage:btndownImage forState:UIControlStateNormal];
[downbtnobj addTarget:self action:#selector(bulletInButtonClicked) forControlEvents:UIControlEventTouchUpInside];
[downLabel addSubview:downbtnobj];
In this code you can see I replace only UILabel by UIView. Now button is showing.
Can any help why subviews not showing on UILabel in iOS8
It's not clear what is different about labels in iOS 8, but if you call layoutIfNeeded on your label, that fixes the problem (it needs to be after you set the frame),
UILabel *downLabel = [[UILabel alloc]init];
downLabel.frame = CGRectMake(0, SCREEN_HEIGHT*0.92, SCREEN_WIDTH,SCREEN_HEIGHT*0.08 );
[downLabel layoutIfNeeded];
[downLabel setBackgroundColor:[UIColor colorWithRed:(66/255.f) green:(67/255.f) blue:(63/255.f) alpha:1]];
downLabel.userInteractionEnabled = YES;
[self.view addSubview:downLabel];
After Edit:
I also found out that if you set the text (any time after you create the label), then the button appears.
Very Simple way you need set clipsToBounds on your UILabel
downLabel.clipsToBounds = YES;

I added the date label and the share button via code. Now I want to add a static button in the right top corner to open a slide out menu(I'm using MMDrawerController). If I'm adding the via code, it's moving with the carousel.
If I'm adding a button on the name label(My App) on the storyboard, it's not getting clicked and the carousel gesture is being registered instead of the button click.
How should I proceed to add a button for a slide out menu on the right ?
-(UIView *)carousel:(iCarousel *)carousel viewForItemAtIndex:(NSInteger)index reusingView:(UIView *)view{
UIView *magView = nil;
CGFloat height = self.myCarousel.bounds.size.height;
CGFloat width = self.myCarousel.bounds.size.width;
//Magazine View
magView = [[UIView alloc] initWithFrame:CGRectMake(0, 40, width/1.35, height/1.75)];
magView.backgroundColor = [UIColor clearColor];
UIImageView *magImage = [[UIImageView alloc] initWithImage:[UIImage imageNamed:#"4 1:2.jpg"]];
magImage.frame = CGRectMake(0, 0, width/1.35, height/1.75);
[magView addSubview:magImage];
//Date Label
UILabel *dateLabel = nil;
dateLabel = [[UILabel alloc] initWithFrame:CGRectMake(0, height/1.7, width/4, height/25)];
dateLabel.backgroundColor = [UIColor clearColor];
dateLabel.text = #"12-03-2017";
dateLabel.font = [UIFont fontWithName:#"Roboto-Black" size:5];
dateLabel.textColor = [UIColor whiteColor];
//Share Button
UIButton *shareButton = nil;
shareButton = [[UIButton alloc] initWithFrame:CGRectMake(width/1.49, height/1.7, height/25, height/25)];
shareButton.backgroundColor = [UIColor clearColor];
[shareButton setBackgroundImage:[UIImage imageNamed:#"share_icon_1x"] forState:UIControlStateNormal];
[magView addSubview:dateLabel];
[magView addSubview:shareButton];
return magView;
}

How do I proceed to add the button ?
Add button to storyboard and after adding carousel programmatically. add code to bring the button to top on view.
[self.view bringSubviewToFront:button];
if you are adding it programmatically then just after [self.view addSubview:carousel];
call [self.view bringSubviewToFront:button](make sure button is added on view before calling it)
I solved the issue. Instead of taking the view of the ViewController I dragged/dropped another view onto the ViewController and displayed the carousel on it. Now I can set the button easily. Thanks for the help though. Cheers
It will help you
[xyzButton.superview setUserInteractionEnabled:YES];

I have navigation bar with custom view on it. UIImageView and UILabel are subviews of titleView. And I add UITapGestureRecognizer to titleView to make it show another UIViewController when the user taps on it. When you tap on titleView other UIViewController opens. But when you click on back button in my titleView size of UIImageView changes. Here is the code
UIView *titleView = [[UIView alloc] initWithFrame: CGRectMake(0, 0, self.view.frame.size.width, 30)];
UILabel *title = [[UILabel alloc] initWithFrame: CGRectMake(0, 0, self.view.frame.size.width/2, 30)];
title.text = _groupName;
[title setTextColor:[self colorFromHexString:#"#474747"]];
[title setFont:[UIFont fontWithName:#"Roboto-Bold" size:16]];
[title setTextAlignment:NSTextAlignmentCenter];
[title setBackgroundColor:[UIColor clearColor]];
_imageView.frame = CGRectMake(0, 0, 30, 30);
_imageView.layer.cornerRadius = 15.0;
_imageView.layer.masksToBounds = YES;
_imageView.layer.borderColor = [UIColor lightGrayColor].CGColor;
_imageView.layer.borderWidth = 0.1;
_imageView.contentMode = UIViewContentModeScaleAspectFit;
title.frame = CGRectMake(title.frame.origin.x+20, title.frame.origin.y, self.view.frame.size.width/2, 30);
UITapGestureRecognizer *recognizer;
recognizer = [[UITapGestureRecognizer alloc]initWithTarget:self action:#selector(titleTapped:)];
titleView.userInteractionEnabled = YES;
[titleView addGestureRecognizer:recognizer];
[titleView addSubview:title];
[titleView setBackgroundColor:[UIColor clearColor]];
[titleView addSubview:_imageView];
self.navigationItem.titleView = titleView;
Here are the images where you can see the changes
I check your code Add clips to bounds and do not need to title frame two times.
_imageView.frame = CGRectMake(0, 0, 30, 30);
_imageView.layer.cornerRadius = 15.0;
_imageView.layer.masksToBounds = YES;
_imageView.clipsToBounds = true;
Rather than setting the frame of the views directly, you might try using Auto Layout; I suspect what's happening is that your custom view is getting re-layed-out after the back button, and it's reverting to the image view's instrinsicSize.
What you could do instead is turn off translatesAutoresizingMaskIntoConstraints on the subviews, and then add constraints to position them, and finally add width and height constraints to the image view.
Using Auto Layout is also recommended if you ever intend to internationalize your app -- if you set up your constraints correctly, then the translated title will fit and you won't have to ever play around with hardcoded values.
Actually i want to place image and label on the toolbar as a UIBarButtonItem and provide a clickable effect to that Button.
So what i have done here is I have created one custom view and placed Image and Label on the same custom view and finally placed this custom view as UIBarButtonItem CustomView.
But when i set target and action for the same UIBarButtonItem, it is not calling the selector method.
The entire code is below.
Can anybody suggest me what's the mistake in my code ? and is there any other approach to achieve the same ????
Early suggestions would be much appreciated.
- (void)viewDidLoad
{
[super viewDidLoad];
[self.navigationController setToolbarHidden:NO];
UIView *customView = [[UIView alloc]
initWithFrame:CGRectMake(0,0,self.navigationController.toolbar.frame.size.width,self.navigationController.toolbar.frame.size.height)];
customView.backgroundColor = [UIColor colorWithRed:62.0/255.0 green:187.0/255.0 blue:150.0/255.0 alpha:1.0];
[self.navigationController.toolbar addSubview:customView];
UIImageView *imgView = [[UIImageView alloc]initWithFrame:CGRectMake(60,0,44,44)];
imgView.image = [UIImage imageNamed:#"documentImage.png"];
[customView addSubview:imgView];
UILabel *lbl = [[UILabel alloc]initWithFrame:CGRectMake(104,0,145,44)];
lbl.text = #"Scan Document";
lbl.textAlignment = NSTextAlignmentLeft;
[customView addSubview:lbl];
UIBarButtonItem *bar = [[UIBarButtonItem alloc]initWithCustomView:customView];
bar.target = self;
bar.action = #selector(scanDocument);
self.toolbarItems = [NSArray arrayWithObjects:bar, nil];
}
If you want to create button right hand side here is the code. i have already implemented it and working fine.
//Button Right side
UIImage *imgFavRest = [UIImage imageNamed:#"documentImage.png"];
UIButton *cart = [UIButton buttonWithType:UIButtonTypeCustom];
[cart setImage:imgFavRest forState:UIControlStateNormal];
cart.frame = CGRectMake(0, 0, imgFavRest.size.width, imgFavRest.size.height);
[cart addTarget:self action:#selector(showCart) forControlEvents:UIControlEventTouchUpInside];
UIBarButtonItem *rightBtn = [[UIBarButtonItem alloc] initWithCustomView:cart];
self.navigationItem.rightBarButtonItem = rightBtn;
Then use method like this . that's all
-(void)cartItemCount{
// Method
}
float textwidth = 50; // according to your text
UIImage *image = [UIImage imageNamed:#"logout"];
UIButton *btn = [UIButton buttonWithType:UIButtonTypeCustom];
btn.bounds = CGRectMake( 10, 0, image.size.width+textwidth, image.size.height );
[btn addTarget:self action:#selector(scanDocument) forControlEvents:UIControlEventTouchUpInside];
[btn setImage:image forState:UIControlStateNormal];
[btn setTitle:#"test" forState:UIControlStateNormal];
[btn setTitleEdgeInsets:UIEdgeInsetsMake(0.0, 5.0, 0.0, 0.0)];
//Adjust the coordinates and size of your button as your requirement.This is a sample code to guide you.
//PS:Take a UIButton in the nib file>Make it a custom button>Connect the IBOutlet to your custom button in the nib file.Thats it.
UIBarButtonItem *rightButton = [[UIBarButtonItem alloc] initWithCustomView:btn];
self.navigationItem.rightBarButtonItem = rightButton;
I see very complicated answers, all of them using code. However, if you are using Interface Builder, there is a very easy way to do this:
Select the button and set a title and an image. Note that if you set
the background instead of the image then the image will be resized if
it is smaller than the button.IB basic image and title
Set the position of both items by changing the edge and insets. You
could even control the alignment of both in the Control section.
IB position set IB Control set
You could even use the same approach by code, without creating UILabels and UIImages inside as other solutions proposed. Always Keep It Simple!
EDIT: Attached a small example having the 3 things set (title, image and background) with correct insets Button preview
Note:: UIBarButtonItem inherits from UIBarItem and NSObject so it doesn't know anything about touches. It would be nice if the docs mentioned that the action and target properties only apply if the custom view is a UIButton.
Imagine I have dialog and size of this dialog is 200x200 and I want to present on the iPhone screen temporary (can dismiss with button).
I try it. but the view controller that I presented is replace current scene (dialog and white background border).
I want to present with custom size (200x200) at center of iPhone screen and see my content as background
I try to set dialog's background colour to clearColor and It doesn't work.
Thanks in advance.
Create your button like this,
[button addTarget:self action:#selector(ButtonFun) forControlEvents:UIControlEventTouchUpInside];
-(void)ButtonFun {
UIView *newView1 = [[UIView alloc] initWithFrame:CGRectMake(0,0,200,200)];
newView1.backgroundColor = [UIColor whiteColor];
UITextView *textView = [[UITextView alloc] initWithFrame:CGRectMake(0, 0, 200, 200)];
textView.text = #"Write your dialog";
[textView setFont:[UIFont fontWithName:#"ArialMT" size:15]];
textView.textAlignment = NSTextAlignmentCenter;
[newView1 addSubview:textView];
newView1.center = self.view.center;
[self.view addSubview:newView1];
}
To remove this UIView use UITapGestureRecognizer,or simply
[newView1 removeFromSuperview];
I'm trying to add multiple subview programmatically, but my buttons inside those subviews are not working. The buttons were also added as subviews programmatically.
Here's the code, hopefully will explain more about what I mean.
self = [super initWithFrame:frame];
if (self) {
// Initialization code
}
[self setBackgroundColor:[UIColor clearColor]];
// UIView container of selected image with comment button.
UIView *containerOfSelectedImage = [[UIView alloc] initWithFrame:CGRectMake(0, 20, 0, 350)];
NSLog(#"%f", self.frame.size.width);
// image view of selected photo by user.
UIImageView *userImage = [[UIImageView alloc]initWithImage:[UIImage imageNamed:#"nature_01.jpg"]];
[userImage setFrame :CGRectMake(0, 0, 340, 300)];
// comment button with action of recodering user's comment.
UIButton *commentButton = [UIButton buttonWithType:UIButtonTypeCustom];
//[commentButton setBackgroundColor : [UIColor clearColor]];
float y = userImage.frame.size.height + 5.0f;
[commentButton setFrame : CGRectMake(32.0f, y, 24.0f, 24.0f)];
[commentButton addTarget:self action:#selector(audioRecordAction) forControlEvents:UIControlEventTouchDown];
[commentButton setImage:[UIImage imageNamed:#"comments-24.png"] forState:UIControlStateNormal];
[containerOfSelectedImage addSubview:userImage];
[containerOfSelectedImage addSubview:commentButton];
[self addSubview:containerOfSelectedImage];
[self addSubView:self.commentContainerView];
return self;
You need to increase the frame of the containerOfSelectedImage. Currently the width is 0.
The containerOfSelectedImage's frame has to be big enough so the button fits inside it. If the button is outside that frame it will show up but you can't touch him.
To debug this issues you can use a tool like Reveal App. If any of your buttons is outside the frame of the parent then the touch will not be detected.
Change [commentButton addTarget:self action:#selector(audioRecordAction) forControlEvents:UIControlEventTouchDown]; to [commentButton addTarget:self action:#selector(audioRecordAction) forControlEvents:UIControlEventTouchUpInside];
