I want to set image as a background on my button. So i create an image:
then I want to implement it as stretchable:
UIButton *button = [[UIButton alloc] initWithFrame:CGRectMake(20, 20, 200, 400)];
[button setTitle:#"Test Button" forState:UIControlStateNormal];
UIImage *buttonImage = [_model.background resizableImageWithCapInsets:UIEdgeInsetsMake(6, 8, 6, 7)]; //this is screen 1
//UIImage *buttonImage = _model.background; //this is screen 2
[button addTarget:self action:#selector(buttonPressed:) forControlEvents: UIControlEventTouchUpInside];
[button setBackgroundImage:buttonImage forState:UIControlStateNormal];
[self addSubview:button];
I want to background stretch like in screen 2 but corners will sharp like screen 1. _model.background is UIImage contains original button background from the top of this post.
Am I using it right? I follow the documentation so UIEdgeInsetsMake(top,left,bottom,right) should be unstreachable corners, right?
According to the docs, the part inside the insets (the part not locked via cap settings) is tiled. So you should have a small 1 pixel region to tile. E.g. make the insets be UIEdgeIndetsMake(20,8,19,7)
This produces:
honestly, this is not the best picture for this effect but, please, try this line:
[button setBackgroundImage:[[UIImage imageNamed:#"image.png"] resizableImageWithCapInsets:UIEdgeInsetsMake(20.f, 62.f, 20.f, 62.f)] forState:UIControlStateNormal];

Hope all of you will be fine. Guys i have a situation, I have a uiview and uibutton as under:
UIView* containerView = [[UIView alloc] initWithFrame:CGRectMake(0, 200, self.view.frame.size.width, 70)];
containerView.backgroundColor = [UIColor whiteColor];
[self.view addSubview:containerView];
UIButton *button = [UIButton buttonWithType:UIButtonTypeRoundedRect];
button.backgroundColor = [UIColor redColor];
[button addTarget:self action:#selector(SettingPressed:) forControlEvents:UIControlEventTouchUpInside];
UIImage *image = [UIImage imageNamed:#"settings_button.png"];
[button setImage:image forState:UIControlStateHighlighted & UIControlStateNormal & UIControlStateSelected];
button.frame = CGRectMake(0,0, 40, 40);
button.center = containerView.center;
[containerView addSubview:button];
The problem is uibutton appear far from uiview instead of in the middle of uiview. What i am mistaking, please guide me.
Thanks.
First, when you change a view's center property the frame property will be changed automatically so you only should set the button center:
button.center = CGPointMake(containerView.frame.size.width / 2,
containerView.frame.size.height / 2);
Now, whenever you change the center property you need to manually tell the view to redraw itself using setNeedsDisplay :
[button setNeedsDisplay]
and lastly, the difference between frame and bounds that frame defines the position and size relative to the parent view while bounds describes the drawing area inside (or outside) the frame.
I'm currently making an iOS 8 application ready for the app store upon iOS 8 release, I don't obviously I cannot show much code as I'm keeping the project very quiet but I am creating a view controller with a scroll view and many objects throughout to create a profile for the user, however I'm trying to add a button to all the user to add projects to their profile and the button won't get added to the scroll view... Is there an unwritten rule with UIButtons and UIScrollViews?
Heres the code I'm using to create the button
UIButton *addProject = [[UIButton alloc] initWithFrame:CGRectMake(210, 285, 100, 18)];
[addProject setTitle:#"Show View" forState:UIControlStateNormal];
[addProject addTarget:self action:#selector(addProjectPressed:) forControlEvents:UIControlEventTouchUpInside];
[_scrollView addSubview:addProject];
Is there something I need to do differently to add it to the scroll view?
EDIT 1: _scrollView.contentSize = CGSizeMake(self.view.frame.size.width, 699);
EDIT 2: Also, the scroll view is created in the storyboard and has a frame of 0, 64, 320, 455 but the content size as above has a larger height
Try with this;
UIButton *addProject = [UIButton buttonWithType: UIButtonTypeRoundedRect];
addProject.frame = CGRectMake(210, 285, 100, 18);
[addProject setTitle:#"Show View" forState:UIControlStateNormal];
[addProject addTarget:self action:#selector(addProjectPressed:) forControlEvents:UIControlEventTouchUpInside];
[_scrollView addSubview:addProject];
Try to add this line;
addProject.backgroundColor = [UIColor redColor];
It's some time happens that it may not appear due to same background color.
UIButton *addProject = [UIButton buttonWithType: UIButtonTypeRoundedRect];
addProject.frame = CGRectMake(210, 285, 100, 18);
[addProject setTitle:#"Show View" forState:UIControlStateNormal];
[addProject addTarget:self action:#selector(addProjectPressed:) forControlEvents:UIControlEventTouchUpInside];
[_scrollView addSubview:addProject];
_scrollView.backgroundColor = [UIColor clearColor];
I am pretty new to iOS development, so this may seem to be a stupid question.. In my xib file, i have taken a UIImageView that will show an image when the page is loaded. But when a user taps on an image, I want the next view to be loaded.. But I am not able to do that because we cannot have a delegate not a target-action mechanism for a UIImage view.. Many places, I found a workaround.. using a button and then placing an image on it, and then using it.. but I want the first way to work.. Please help..
use UITapGestureRecognizer ,and Don't forget to set imageView.userInteractionEnabled = YES; because by default image not having UserInteraction.
UITapGestureRecognizer *singleTap = [[UITapGestureRecognizer alloc] initWithTarget:self action:#selector(handleSingleTap:)];
[singleTap setNumberOfTapsRequired:1];
[imageView addGestureRecognizer:singleTap];
-(void)handleSingleTap:(id)sender {
// push you view here
}
(OR) If you want
take button with BackGround image.
UIButton *button = [UIButton buttonWithType:UIButtonTypeCustom];
button.frame = CGRectMake(270,10,30,30);
[button setBackgroundImage:[UIImage imageNamed:#"image.png"] forState:UIControlStateNormal];
[button addTarget:self action:#selector(action:) forControlEvents:UIControlEventTouchUpInside];
Instead of Using UIImageView, you can use UIButton.
UIButton *myBtn = [UIButton buttonWithType:UIButtonTypeCustom];
[myBtn setBackgroundImage:[UIImage imageNamed:#"your_image_Name"] forState:UIControlStateNormal];
[myBtn setBackgroundImage:[UIImage #"your_image_Name"] forState:UIControlStateHighlighted];
[myBtn addTarget:self action:#selector(buttonAction:) forControlEvents:UIControlEventTouchUpInside];
also write button action:
-(void)buttonAction:(id)sender {
// Do whatever you want
}
In Case of XIB, Just use UIButton instead of UIImageView and set Background Image for both state Normal & Highlighted as you want. Rest you can manage button's action from XIB.
You can also add a fully transparent UIButton on top of your UIImageView... It should be preferred as each element has a clean semantics.
I have created a springboard like panel containing buttons as follows:
-(void)configurePanel{
self.criteriaPanel.scrollEnabled=YES;
self.criteriaPanel=[[UIScrollView alloc] initWithFrame:CGRectMake(
0.0f,
0.0f,
[UIScreen mainScreen].bounds.size.width,
(BUTTON_HEIGHT+(3*BUTTON_Y_OFFSET))
)];
UIView *scrollViewContent=[[UIView alloc]init];
NSArray *criteriaTypeButtonTitles=[NSArray arrayWithObjects:
#"Option1",
#"Option2",
#"Option3",
#"Option4",
#"Option5",
#"Option6",
nil
];
for (int i=0; i<[criteriaTypeButtonTitles count]; i++) {
UIButton *button = [UIButton buttonWithType:UIButtonTypeCustom];
button.tag=i;
button.frame = CGRectMake(
(((BUTTON_X_OFFSET*i)+(BUTTON_WIDTH*i))+BUTTON_X_OFFSET)
, BUTTON_Y_OFFSET
, BUTTON_WIDTH
, BUTTON_HEIGHT
);
[button setTitle:[criteriaTypeButtonTitles objectAtIndex:i] forState:UIControlStateNormal];
[button setTitleColor:[UIColor blueColor] forState:UIControlStateHighlighted];
button.titleLabel.font=[UIFont systemFontOfSize:13.0f];
[button setBackgroundColor:[UIColor grayColor]];
[button.layer setCornerRadius:10.0f];
[button.layer setBorderWidth:1.0f];
[button addTarget:self action:#selector(sortByButtonTap:) forControlEvents:UIControlEventTouchDown];
[scrollViewContent addSubview:button];
}
//based upon # of buttons
self.criteriaPanel.contentSize=CGSizeMake(
(([criteriaTypeButtonTitles count]*BUTTON_WIDTH)+([criteriaTypeButtonTitles count]*BUTTON_X_OFFSET)),
(BUTTON_HEIGHT+(2*BUTTON_Y_OFFSET)));
[self.criteriaPanel addSubview:scrollViewContent];
[self.view addSubview:self.criteriaPanel];
}
The panel displays correctly and scrolls, but the tap events (sortByButtonTap:) for the buttons are never called. I suspect this is related to the buttons being contained in a view which is contained in the scrollview. After reading a number of other questions and the docs I still can't figure out what the solution should be.
EDIT:
I experimented w/ adding the buttons to the UIScrollView (self.criteriaPanel) directly and the button taps call sortByButtonTap: so it is something to do w/ the buttons being in the scrollViewContent.
You might need to set userInteractionEnabled on the containing view scrollViewContent for the button to receive touch events:
[scrollViewContent setUserInteractionEnabled:YES];
What if you try:
[button setExclusiveTouch:YES];
Buttons tend to work abnormally when they are inside a view that also handles touch events.
Follow this code for your query,
Add UIButton in Scrollview
scrollview.pagingEnabled = YES;
UIButton *button = [UIButton buttonWithType:UIButtonTypeCustom];
button.frame = CGRectMake();
[button setTitle:#"X" forState:UIControlStateNormal];
[button setTitleColor:[UIColor clearColor] forState:UIControlStateNormal];
[button addTarget:self action:#selector(btnCloseClicked:withEvent:) forControlEvents:UIControlEventTouchUpInside];
[button addTarget:self action:#selector(btnCloseDraged:withEvent:) forControlEvents:UIControlEventTouchDragInside];
[button addTarget:self action:#selector(btnCloseDragedEnd:withEvent:) forControlEvents:UIControlEventTouchDragExit];
[scrollview addSubview:button];
scrollview.userInteractionEnabled = YES;
you can put this three methods of button manually.
Let me know if you still have query.
instead of:
[button addTarget:self
action:#selector(sortByButtonTap:)
forControlEvents:UIControlEventTouchDown];
try:
[button addTarget:self
action:#selector(sortByButtonTap:)
forControlEvents:UIControlEventTouchUpInside];
I think your problem is just that you set the wrong UIControlEvent to the UIButton. Change from UIControlEventTouchDown to UIControlEventTouchUpInside. If you connect a UIButton inside the Interface Builder it will always set it to this UIControlEvent:
Another reason:
Otherwise your UIScrollView controls the interactions because it needs to know if you want to scroll it. If you place UIButtons inside your UIScrollView they will be accessible but always with a little delay. This is why you should maybe change the settings for the UIScrollView:
You can disable delays content touches and UIButtons will be accessible immediately
I have a round button, but i will make it have a backgroud with image.
but when i do it, by setting the (what) property to an image, the button becomes rectangle because the image is a rectangle. How do I keep the button round?
Simply by doing this
#import <QuartzCore/QuartzCore.h>
myButton.layer.cornerRadius = 8;
Tested Code:
.h
-(void)vijayWithApple;
.m
-(void)vijayWithApple{
NSLog(#"vijayWithApple Called");
}
UIButton *button = [UIButton buttonWithType:UIButtonTypeCustom];
[button setImage:[UIImage imageNamed:#"Micky.png"] forState:UIControlStateNormal];
[button addTarget:self action:#selector(vijayWithApple) forControlEvents:UIControlEventTouchUpInside];
[button setTitle:#"Show View" forState:UIControlStateNormal];
button.frame = CGRectMake(135.0, 180.0, 40.0, 40.0);//width and height should be same value
button.clipsToBounds = YES;
button.layer.cornerRadius = 20;//half of the width
button.layer.borderColor=[UIColor redColor].CGColor;
button.layer.borderWidth=2.0f;
[self.view addSubview:button];
Restut
Best solution I have found especially for UITableCell. I put the code in awakeFromNib and worked right off the bat.
