I want to add a UIImageView and UIButton inside UITextView. UITextView height changes on clicking enter button. I want the UIView with image and cancel button to be placed above the text. Is it possible?
I have tried using Bezier path. But my image comes inline with the text, but I want my text to come in next line. Also the button is not tapable when I add it in this method.
UIBezierPath * imgRect = [UIBezierPath bezierPathWithRect:CGRectMake(0, 0, 50, 50)];
self.commentText.textContainer.exclusionPaths = #[imgRect];
UIImageView *spacerView = [[UIImageView alloc] initWithFrame:CGRectMake(0, 0, 50, 50)];
spacerView.image = _pickedImageForComment;
UIButton *cancelButton = [UIButton buttonWithType:UIButtonTypeCustom];
[cancelButton addTarget:self
action:#selector(buttonsClicked:)
forControlEvents:UIControlEventTouchUpInside];
cancelButton.frame = CGRectMake(30, 0, 19, 19);
[cancelButton setImage:[UIImage imageNamed:#"remove_image"] forState:UIControlStateNormal];
[spacerView addSubview:cancelButton];
[_commentText addSubview:spacerView];

I'm new in objective-C and I've create a project that use a button to change some elements from my view. I would like that depending on what part of the button I click, it displays different elements than previous.
For exemple when I click on the left area from button a red circle appears and when I click in the middle, it's the blue circle that appears and in the right area it's a green circle.
I tried searching on google and stackoverflow but I have trouble understanding how the selector used in this case. Could someone help me?
PS: Sorry for the mistakes, my English is not very good
I help you.
First you need the create the small custom view programmatically or through the xib or storyboard
UIView *viewButton = [[UIView alloc] initWithFrame: CGRectMake ( 100, 100, 300, 300)];
[self.view addSubView:viewButton];
Then Create the 3 buttons inside the viewButton
//First Button
UIButton *buttonLeftRed = [UIButton buttonWithType:UIButtonTypeCustom];
OR
UIButton *buttonLeftRed = [UIButton buttonWithType:UIButtonTypeSystem];
buttonLeftRed.frame = CGRectMake(0, 0, 100, 100);
buttonLeftRed.tag = 1;
[buttonLeftRed setTitle:#"Red" forState:UIControlStateNormal];
[buttonLeftRed addTarget:self
action:#selector(actionPressMeOne:) forControlEvents:UIControlEventTouchUpInside];
[viewButton addSubview:buttonLeftRed];
//Second Button
UIButton *buttonMiddleBlue = [UIButton buttonWithType:UIButtonTypeCustom];
OR
UIButton *buttonMiddleBlue = [UIButton buttonWithType:UIButtonTypeSystem];
buttonMiddleBlue.frame = CGRectMake(100, 0, 100, 100);
buttonMiddleBlue.tag = 2;
[buttonMiddleBlue setTitle:#"Blue" forState:UIControlStateNormal];
[buttonMiddleBlue addTarget:self
action:#selector(actionPressMeSecond:) forControlEvents:UIControlEventTouchUpInside];
[viewButton addSubview:buttonMiddleBlue];
//Third Button
UIButton *buttonRightGreen = [UIButton buttonWithType:UIButtonTypeCustom];
OR
UIButton *buttonRightGreen = [UIButton buttonWithType:UIButtonTypeSystem];
buttonRightGreen.frame = CGRectMake(200, 0, 100, 100);
buttonRightGreen.tag = 3;
[buttonRightGreen setTitle:#"Blue" forState:UIControlStateNormal];
[buttonRightGreen addTarget:self
action:#selector(actionPressMeThird:) forControlEvents:UIControlEventTouchUpInside];
[viewButton addSubview:buttonRightGreen];
If you want to change circle button, you have to import the Quartzcore Framework
#import <QuartzCore/QuartzCore.h>
#pragma mark - UIButton Action Methods
//First
- (void)actionPressMeOne:(UIButton *)sender
{
NSLog(#"Pressed Button Tag is - %#",sender.tag);
UIButton *button = sender;
//Then do whatever you want to do here
//half of the width
button.layer.cornerRadius = button.frame.size.width/2.0f;
button.layer.borderColor=[UIColor redColor].CGColor;
button.layer.borderWidth=2.0f;
button.clipsToBounds = YES;
[button setBackgroundColor:[UIColor redColor]];
}
//Second
- (void)actionPressMeSecond:(UIButton *)sender
{
NSLog(#"Pressed Button Tag is - %#",sender.tag);
UIButton *buttonTwo = sender;
//Then do whatever you want to do here
//half of the width
buttonTwo.layer.cornerRadius = button.frame.size.width/2.0f;
buttonTwo.layer.borderColor=[UIColor blueColor].CGColor;
buttonTwo.layer.borderWidth=2.0f;
buttonTwo.clipsToBounds = YES;
[buttonTwo setBackgroundColor:[UIColor blueColor]];
}
//Third
- (void)actionPressMeThird:(UIButton *)sender
{
NSLog(#"Pressed Button Tag is - %#",sender.tag);
UIButton *buttonThree = sender;
//Then do whatever you want to do here
//half of the width
buttonThree.layer.cornerRadius = button.frame.size.width/2.0f;
buttonThree.layer.borderColor=[UIColor greenColor].CGColor;
buttonThree.layer.borderWidth=2.0f;
buttonThree.clipsToBounds = YES;
[buttonThree setBackgroundColor:[UIColor greenColor]];
}
Thank You:-)
I have used the title inset to display the text name under the UIButton.
Here's my code and the output:
[button setTitleEdgeInsets:UIEdgeInsetsMake(60, 0, 0, 0)];
Here's my expected output:
I have used the UIButton and set the title and UIImage as background. So how to show the title label under the UIButton?
What you're trying to do is correct; you just need to set the inset edges as done below. Then you need to increase your button frame so that it can hold the title and image in the same time.
[button setTitleEdgeInsets:UIEdgeInsetsMake(60, 0, 0, 0)];
[button setImageEdgeInsets:UIEdgeInsetsMake(0.0f, 0.f, button.titleLabel.frame.size.height, 0.f)];
This can also be done via storyboards as #VD Patel suggests that is up to you which approach you prefer.
You could also do this with a separate UIImageview and a button that would be easier to handle and would be more efficient.
Please Select button in xib first. then select Attribute Inspector, in this Select Title in "Edge" and set appropriate "Inset" as per Requirements.
please take a look with below code and set insets as per your Requirements.
UIButton *myButton = [UIButton buttonWithType:UIButtonTypeCustom];
myButton.frame = CGRectMake(0, 0, self.view.bounds.size.width, 40);
[myButton setImage:[UIImage imageNamed:#"imageName"] forState:UIControlStateNormal];
[myButton setTitle:#"Rate us on app store" forState:UIControlStateNormal];
[myButton setTitleEdgeInsets:UIEdgeInsetsMake(2, 50, 2, 20)];//set ur title insects myButton
[myButton setImageEdgeInsets:UIEdgeInsetsMake(2, -200, 2, 2)];//make negative edge for left side
[myButton setBackgroundColor:[UIColor greenColor]];
[self.view myButton];
Create an UIImageView,UILabel and UIButton. And later add ImageView and Label as subview to Button.
UILabel *lbl = [[UILabel alloc] initWithFrame:CGRectMake(0, 200, 200, 100)];
lbl.textAlignment = NSTextAlignmentCenter;
[lbl setText:#"Mono"];
UIImageView * imgView = [[UIImageView alloc] initWithFrame:CGRectMake(0, 0, 200, 200)];
imgView.image = [UIImage imageNamed:#"your_image.png"];
[imgView setUserInteractionEnabled:NO];
UIButton *btn = [UIButton buttonWithType:UIButtonTypeCustom];
[btn addSubview:imgView];
[btn addSubview:lbl];
[btn setFrame:CGRectMake(0, 20, 200, 300)];
[btn addTarget:self action:#selector(OnButtonClick:) forControlEvents:UIControlEventTouchUpInside];
[self.view addSubview:btn];
Try adding this code in viewDidLoad Method.
I have one UIButton. In that UIButton i have to show text and image. Image should be displayed after the text. Based on text i want to adjust the button frame.
See the image. After the text "I am a Button", i want to add a image like arrow.
UIButton *titleButton = [UIButton buttonWithType:UIButtonTypeCustom];
NSString *name = #"I am a button";
titleButton.titleLabel.text = [NSString stringWithFormat:#"%#", name];
titleButton.titleLabel.textColor = [UIColor whiteColor];
CGSize stringSize = [name sizeWithAttributes:#{NSFontAttributeName: [UIFont fontWithName:#"MyriadPro-Cond" size:24]}];
CGRect frame = CGRectMake(300, 30, stringSize.width, 30);
//frame.size.width = stringSize.width;
[titleButton setFrame:frame];
UIImageView *image = [[UIImageView alloc]initWithImage:[UIImage imageNamed:#"home.png"]];
image.frame = CGRectMake(stringSize.width, 14, 20, 13);
titleButton.imageEdgeInsets = UIEdgeInsetsMake(0, 0, stringSize.width+20, 0);
[titleButton addSubview:image];
I written code like this. But it is not working. Anyone can make it correct. Thanks in advance
You dont have to add a UIImageView over the UIButton to get this behaviour. The UIButton has itself has some properties. Set the orange image as the background image of the button, set the arrow image as the image of the button. Then adjust the insets of the title and the image of the button to move the title to the left and the arrow image to the right.
[btn setBackgroundImage:[UIImage imageNamed:#"orange_bg"] forState:UIControlStateNormal];
[btn setImage:[UIImage imageNamed:#"arrow"] forState:UIControlStateNormal];
[btn setTitleEdgeInsets:UIEdgeInsetsMake(0, 0, -60, 0)];
[btn setImageEdgeInsets:UIEdgeInsetsMake(0, 0, 125, 0)];
You have to adjust the insets according to your image and button sizes.
I have a UIButton and the button background is set to an image. Added
an image view on the top right corner of the button and I set it
to different image when the button is clicked to show the selection.
When I try to automate this using instruments. I don’t see any subviews
(image views) in the UIAutomator.logElementTree()method does not show
any image views.
How to identify the image views added as subview in the UIButton?
Here is the code.
UIButton *button = [UIButton buttonWithType:UIButtonTypeCustom];
button.frame = CGRectMake(40, 40, 100, 100);
[button addTarget:self action:#selector(didTapButton:) forControlEvents:UIControlEventTouchUpInside];
[button setBackgroundImage:[UIImage imageNamed:#“testImage.png”] forState:UIControlStateNormal];
UIImageView *imageview = [[UIImageView alloc] initWithImage:image];
imageview.frame = CGRectMake(70,30,20,20);
[button addSubview:imageview];
You have to set the accessibilityEnabled & accessibilityLabel.
UIButton *button = [UIButton buttonWithType:UIButtonTypeCustom];
button.frame = CGRectMake(40, 40, 100, 100);
[button addTarget:self action:#selector(didTapButton:) forControlEvents:UIControlEventTouchUpInside];
button.accessibilityEnabled = YES;
button.accessibilityLabel =#"My Button";
[button setBackgroundImage:[UIImage imageNamed:#“testImage.png”] forState:UIControlStateNormal];
UIImageView *imageview = [[UIImageView alloc] initWithImage:image];
imageview.accessibilityEnabled = YES;
imageview.accessibilityLabel = #"My Image";
imageview.frame = CGRectMake(70,30,20,20);
[button addSubview:imageview];
Refer this tutorial
Sweet Angel's answer is enough if you have a single UIImageView subview. However, I would suggest using tags to identify subviews.
imageView.tag = 1346;//Any arbitrary number (I am unsure if there are any limitations to the values you can use, but all 4 digit numbers work fine for me).
Then to get the imageView:
UIImageView* imageView = (UIImageView*)[button viewWithTag:1346];
That's it.
If you want to identify imageview on button taped, try following code :
- (IBAction)didTapButton:(UIButton *)sender
{
for (id view in sender.subviews)
{
if ([view isKindOfClass:[UIImageView class]])
{
NSLog(#"Image view captured.....");
}
}
}
I've been using Interface Builder and storyboard to make my application, but for this signature capturing API, everything was done in code.
I'm trying to implement it to my application, but I can't figure out how to add an UIView and Buttons on to my scrollview.
I got it to appear in my view controller, but it isn't connected to the scrollview at all; it appears on top.
Here's my code.
- (void)viewDidLoad
{
[super viewDidLoad];
CGFloat padding = self.view.frame.size.width/15;
UIView *autoGraphView = [[[UIView alloc] initWithFrame:CGRectMake(padding, 300, 280, 160)] autorelease];
autoGraphView.layer.borderColor = [UIColor lightGrayColor].CGColor;
autoGraphView.layer.borderWidth = 3;
autoGraphView.layer.cornerRadius = 10;
[autoGraphView setBackgroundColor:[UIColor whiteColor]];
[self.view addSubview:autoGraphView];
self.autoGraph = [T1Autograph autographWithView:autoGraphView delegate:self];
[autoGraph setLicenseCode:#"4fabb271f7d93f07346bd02cec7a1ebe10ab7bec"];
[autoGraph setShowDate:YES];
[autoGraph setShowHash:YES];
UIButton *clearButton = [UIButton buttonWithType:UIButtonTypeRoundedRect];
// init withFrame:CGRectMake (50, 300, 200, 60)];
[clearButton setFrame:CGRectMake(padding, 480, 130, 30)];
[clearButton setTitle:#"Clear" forState:UIControlStateNormal];
[clearButton setTitleColor:[UIColor blackColor] forState:UIControlStateNormal];
[clearButton addTarget:self action:#selector(clearButtonAction:) forControlEvents:UIControlEventTouchUpInside];
[self.view addSubview:clearButton];
UIButton *autoDone = [UIButton buttonWithType:UIButtonTypeRoundedRect];
// initWithFrame:CGRectMake (50, 300, 200, 60)];
[autoDone setFrame:CGRectMake(150 + padding, 480, 130, 30)];
[autoDone setTitle:#"Done" forState:UIControlStateNormal];
[autoDone setTitleColor:[UIColor blackColor] forState:UIControlStateNormal];
[autoDone addTarget:self action:#selector(doneButtonAction:) forControlEvents:UIControlEventTouchUpInside];
[self.view addSubview:autoDone];
}
You need to add the subviews to the scrollview, if the root view of your viewcontroller is not the scrollview, you need to get access to it one way or another, typically through an IBOutlet, and add them that way
