How to make a UIImageView a button? - ios

I have a UIImageView like so:
UIImage *image = [UIImage imageNamed:#"test.png"];
UIImageView *imageView = [[UIImageView alloc] initWithImage:image];
imageView.frame = CGRectMake(0, 0, 30, 30);
imageView.layer.cornerRadius = 5.0;
imageView.layer.masksToBounds = YES;
imageView.layer.borderColor = [UIColor lightGrayColor].CGColor;
imageView.layer.borderWidth = 0.1;
[self.view addSubview:imageView];
Couple of issues/questions:
How do I make this a clickable button?
I want to link to Settings (in my app) but do I have to create that image wheel like the settings icon that so many apps use or is it standard icon in iOS 7?
This is the icon I'm talking about:
Why doesn't my border show up?

1) If you want a button, you should use a UIButton and use [UIButton setImage: forState:]
2) Alternatively, you can add a UITapGestureRecognizer to your current UIImageView

here 2 choice u have to use your method
.h file
#import <QuartzCore/QuartzCore.h> //for radius and corner
1. UIButton
UIButton *btn1 = [UIButton buttonWithType:UIButtonTypeCustom];
[btn1 setTitle:#"Cool title" forState:UIControlStateNormal];
[btn1 setFrame:CGRectMake(7, 7, 150, 160)];
[btn1 setImage:[UIImage imageNamed:#"test.png"] forState:UIControlStateNormal];
[btn1 addTarget:self action:#selector(selectFav) forControlEvents:UIControlEventTouchUpInside];
[self.view addSubview:btn1];
-(void) selectFav
{ //what ever you do like
}
2. UITap Gesture for UIImage View
UIImage *image = [UIImage imageNamed:#"test.png"];
UIImageView *imageView = [[UIImageView alloc] initWithImage:image];
imageView.frame = CGRectMake(0, 0, 30, 30);
imageView.layer.cornerRadius = 5.0;
imageView.layer.masksToBounds = YES;
imageView.layer.borderColor = [UIColor lightGrayColor].CGColor;
imageView.layer.borderWidth = 0.1;
UITapGestureRecognizer *tapGesture1 = [[UITapGestureRecognizer alloc] initWithTarget:self action:#selector(tapGesture:)];
tapGesture1.numberOfTapsRequired = 1;
[tapGesture1 setDelegate:self];
[imgView addGestureRecognizer:tapGesture1];
[self.view addSubview:imageView];
- (void) tapGesture: (id)sender
{
//handle Tap...
}

Try:
UIImage *image = [UIImage imageNamed:#"test.png"];
UIImageView *imageView = [[UIImageView alloc] initWithImage:image];
imageView.frame = CGRectMake(0, 0, 30, 30);
imageView.layer.cornerRadius = 5.0;
imageView.layer.masksToBounds = YES;
imageView.layer.borderColor = [UIColor lightGrayColor].CGColor;
imageView.layer.borderWidth = 0.1;
/* Here's the button Start */
UIButton *theButton = [[UIButton alloc]initWithFrame:CGRectMake(imageView.frame.origin.x, imageView.frame.origin.y, imageView.frame.size.width, imageView.frame.size.height)];
theButton.backgroundColor = [UIColor clearColor];
theButton.showsTouchWhenHighlighted = YES;
[theButton addTarget:self action:#selector(yourAction) forControlEvents:UIControlEventTouchUpInside];
[imageView addSubview:theButton];
/* Here's the button End */
[self.view addSubview:imageView];
Your border:
0.1 means is 1/10th of a point - try 1.0 for a nice fine line
Also set:
imageView.clipsToBounds = YES;

1:if you have image view and want to clickable
UIImage *image = [UIImage imageNamed:#"test.png"];
UIImageView *imageView = [[UIImageView alloc] initWithImage:image];
2: Add gesture to image view like this, but don’t forget to setUserInteractionEnabled:YES
UITapGestureRecognizer *TapGestureRecognizer = [[UITapGestureRecognizer alloc] initWithTarget:self action:#selector(markerMove:)];
[TapGestureRecognizer setNumberOfTapsRequired:1];
[TapGestureRecognizer setNumberOfTouchesRequired:1];
[imageView setUserInteractionEnabled:YES];
[imageView addGestureRecognizer: TapGestureRecognizer];

Wrong UIImageView dimensions on navigationItem

I am trying to add an image on navigation bar but the dimensions are wrong.
UIImageView* menuButton=[[UIImageView alloc]initWithFrame:CGRectMake(4, 7, 20, 20)];
menuButton.image=[UIImage imageNamed: Model.icon.MapList];
UIBarButtonItem *accountBarItem = [[UIBarButtonItem alloc] initWithCustomView:menuButton];
self.navigationItem.leftBarButtonItem = accountBarItem;
It seams that I don't have any control on the dimensions of the image, because when I change the values of initWithFrame nothing changes.
Also this problem appears only on iPhones greater than iPhone 5 model.
What am I missing?
You can just use simple button and set image for it.
UIButton *b = [UIButton buttonWithType:UIButtonTypeCustom];
[b setFrame:CGRectMake(0.0f, 0.0f, 25.0f, 25.0f)];
[b addTarget:self action:#selector(randomMsg) forControlEvents:UIControlEventTouchUpInside];
[b setImage:[UIImage imageNamed: Model.icon.MapList] forState:UIControlStateNormal];
UIBarButtonItem *item = [[UIBarButtonItem alloc] initWithCustomView:b];
self.navigationItem.leftBarButtonItem = item;
If you have wrong aspect ratio , you can use
[[b imageView] setContentMode: UIViewContentModeScaleAspectFit];
I'd recommend adding a border to your image view so you can see what's going on.
Here's what you're currently experiencing (using the imageView directly as the custom view of the bar button item):
- (void)_addImageViewToLeftButtonItemWithoutOuterView {
UIImageView *profileImageView = [[UIImageView alloc] initWithImage:[UIImage imageNamed:#"Homer.jpg"]];
[profileImageView setFrame:CGRectMake(0, 0, 40, 40)];
profileImageView.layer.cornerRadius = 20.0f;
profileImageView.layer.masksToBounds = YES;
profileImageView.clipsToBounds = YES;
profileImageView.layer.borderColor = [UIColor blackColor].CGColor;
profileImageView.layer.borderWidth = 1.0f;
UIBarButtonItem *rbi = [[UIBarButtonItem alloc] initWithCustomView:profileImageView];
self.navigationItem.leftBarButtonItem = rbi;
}
This is what it looks like without aspect fit:
And with aspect fit set:
And this is what I believe you want:
- (void)_addImageViewToLeftButtonItemWithOuterView {
UIView *profileView = [[UIView alloc] initWithFrame:CGRectMake(0, 0, 40, 40)];
profileView.layer.borderColor = [[UIColor redColor] CGColor];
profileView.layer.borderWidth = 2.0f;
UIImageView *profileImageView = [[UIImageView alloc] initWithImage:[UIImage imageNamed:#"Homer.jpg"]];
profileImageView.contentMode = UIViewContentModeScaleAspectFit;
[profileImageView setFrame:CGRectMake(0, 0, 40, 40)];
profileImageView.layer.cornerRadius = 20.0f;
profileImageView.layer.masksToBounds = YES;
profileImageView.clipsToBounds = YES;
profileImageView.layer.borderColor = [UIColor blackColor].CGColor;
profileImageView.layer.borderWidth = 1.0f;
[profileView addSubview:profileImageView];
UIBarButtonItem *lbi = [[UIBarButtonItem alloc] initWithCustomView:profileView];
self.navigationItem.leftBarButtonItem = lbi;
}
Which results in this:
As you probably noticed, the sorta trick here is that you don't want to add the image view directly as the custom view within initWithCustomView of the UIBarButtonItem. Instead you want to use an outer view to hold the imageView, then you can adjust the frame of your subview to move it around.
Here's one more example if you wanted the image further to the right (obviously you won't want the border for the outer image view, but I've just left it there for demonstration purposes):
- (void)_addImageViewToLeftButtonItemWithOuterView {
// adjust this to 80 width (it always starts at the origin of the bar button item
UIView *profileView = [[UIView alloc] initWithFrame:CGRectMake(0, 0, 80, 40)];
profileView.layer.borderColor = [[UIColor redColor] CGColor];
profileView.layer.borderWidth = 2.0f;
UIImageView *profileImageView = [[UIImageView alloc] initWithImage:[UIImage imageNamed:#"Homer.jpg"]];
profileImageView.contentMode = UIViewContentModeScaleAspectFit;
// and adjust this to be offset by 40 (move it to the right some)
[profileImageView setFrame:CGRectMake(40, 0, 40, 40)];
profileImageView.layer.cornerRadius = 20.0f;
profileImageView.layer.masksToBounds = YES;
profileImageView.clipsToBounds = YES;
profileImageView.layer.borderColor = [UIColor blackColor].CGColor;
profileImageView.layer.borderWidth = 1.0f;
[profileView addSubview:profileImageView];
UIBarButtonItem *lbi = [[UIBarButtonItem alloc] initWithCustomView:profileView];
self.navigationItem.leftBarButtonItem = lbi;
}

Unable to set Background only for UiImageView only

Im trying to give a background for an image view only as white. Following is my code.
dataArray = [[NSMutableArray alloc] init];
[dataArray addObject:#"Knowledge"];
[dataArray addObject:#"Client"];
float screenWidth = [UIScreen mainScreen].bounds.size.width;
float pickerWidth = screenWidth * 3 / 4;
float xPoint = screenWidth / 2 - pickerWidth / 2;
pickerView = [[UIPickerView alloc] init];
pickerView.transform = CGAffineTransformMakeScale(1, 1);
[pickerView setDataSource: self];
[pickerView setDelegate: self];
[pickerView setFrame: CGRectMake(xPoint, 200.0f, pickerWidth, 200.0f)];
pickerView.showsSelectionIndicator = YES;
[pickerView selectRow:2 inComponent:0 animated:YES];
UIImageView *imageview = [[UIImageView alloc]
initWithFrame:CGRectMake(30, 20, 300, 400)];
[imageview setImage:[UIImage imageNamed:#"logo.png"]];
[imageview setContentMode:UIViewContentModeScaleAspectFit];
[imageview setBackgroundColor: [UIColor whiteColor]];
[self.view addSubview:imageview];
[self.view addSubview: pickerView];
Im facing two problems while doing so,
The background colour is being applied for both UIImageView and UiPickerView thought I have specified specifically as [imageview setBackgroundColor: [UIColor whiteColor]]; when it has to be only for UiImage.
The alignment changes when the phone is in landscape mode though I have given a proper coordinates. How can I sort this out?
Set pickerview's background color like,
pickerView.backgroundColor = [UIColor lightGrayColor]; //desired color
hope this will help :)
Try this code:
imageView.backgroundColor = [UIColor clearColor];
imageView.opaque = NO;
Try this :-
UIImageView *backgroundView = [[UIImageView alloc] initWithImage:[UIImage imageNamed:#"background"]];
[self.view addSubview:backgroundView];

here I am trying to make to click listener, first is on button and another is on tap in any part of this window like as textField etc. so my two new view will push
Change the buttons to properties.
Give the buttons tags.
Logically
determine by identifying the sender and see if it is > or < the other
button (which you need to keep in memory by making them properties or
instance variables).
load custom Xibs, and all of these will work with 0 lines of code.

Showing UIButton Done on UIScrollview for images

Want to show UIButton done on UIScrollView for images. With the below code UIButton is showing but when I scroll UIImageViews, it shows only on very first imageview where as I want UIButton done should show on all image views in UIScrollView.
- (void)viewDidLoad
{
self.view.backgroundColor = [UIColor blackColor];
UIScrollView *imageScrollView = [[UIScrollView alloc] initWithFrame:CGRectMake(0, 0, self.view.frame.size.width, self.view.frame.size.height)];
UIButton *myButton = [UIButton buttonWithType:UIButtonTypeCustom];
[myButton addTarget:self action:#selector(dismissView:) forControlEvents:UIControlEventTouchUpInside];
myButton.frame = CGRectMake(0, 0, 60, 35);
[myButton.layer setMasksToBounds:YES];
[myButton.layer setCornerRadius:10.0f];
myButton.layer.borderWidth = 2;
myButton.layer.borderColor = [[UIColor whiteColor] CGColor];
[myButton setTitle:#"Done" forState:UIControlStateNormal];
myButton.backgroundColor = [UIColor blackColor];
UIBarButtonItem *button = [[UIBarButtonItem alloc] initWithCustomView:myButton];
[[self navigationItem] setRightBarButtonItem:button animated:YES];
imageScrollView.pagingEnabled = YES;
NSInteger numberOfViews = 61;
for (int i = 0; i < numberOfViews; i++) {
CGFloat xOrigin = i * self.view.frame.size.width;
NSString *imageName = [NSString stringWithFormat:#"image%d.png", i];
UIImage *image = [UIImage imageNamed:imageName];
UIImageView *imageView = [[UIImageView alloc] initWithImage:image];
imageView.frame = CGRectMake(xOrigin, 0, self.view.frame.size.width, self.view.frame.size.height);
[imageScrollView addSubview:imageView];
[imageScrollView addSubview:myButton];
[imageView release];
}
imageScrollView.contentSize = CGSizeMake(self.view.frame.size.width * numberOfViews, self.view.frame.size.height);
[self.view addSubview:imageScrollView];
[imageScrollView release];
}
How should I code it that UIButton Done should show on all image views when I scroll it.
Add your UIButton in for loop i.e. it can add each time when your new ImageView is add.
And change its x_Origin for each imageView -
- (void)viewDidLoad
{
[super viewDidLoad];
// Do any additional setup after loading the view, typically from a nib.
UIScrollView *imageScrollView = [[UIScrollView alloc] initWithFrame:CGRectMake(0, 0, self.view.frame.size.width, self.view.frame.size.height)];
imageScrollView.pagingEnabled = YES;
NSInteger numberOfViews = 61;
for (int i = 0; i < numberOfViews; i++)
{
CGFloat xOrigin = i * self.view.frame.size.width;
UIButton *myButton = [UIButton buttonWithType:UIButtonTypeCustom];
[myButton addTarget:self action:#selector(dismissView) forControlEvents:UIControlEventTouchUpInside];
myButton.frame = CGRectMake(xOrigin, 0, 60, 35);
[myButton setTitle:#"Done" forState:UIControlStateNormal];
myButton.backgroundColor = [UIColor blackColor];
[myButton.layer setMasksToBounds:YES];
[myButton.layer setCornerRadius:10.0f];
myButton.layer.borderWidth = 2;
myButton.layer.borderColor = [[UIColor whiteColor] CGColor];
NSString *imageName = [NSString stringWithFormat:#"image%d.png", i];
UIImage *image = [UIImage imageNamed:imageName];
UIImageView *imageView = [[UIImageView alloc] initWithImage:image];
imageView.frame = CGRectMake(xOrigin, 0, self.view.frame.size.width, self.view.frame.size.height);
[imageScrollView addSubview:imageView];
[imageScrollView addSubview:myButton];
}
imageScrollView.contentSize = CGSizeMake(self.view.frame.size.width * numberOfViews, self.view.frame.size.height);
[self.view addSubview:imageScrollView];
}
Remove these 2 lines
UIBarButtonItem *button = [[UIBarButtonItem alloc] initWithCustomView:myButton];
[[self navigationItem] setRightBarButtonItem:button animated:YES];
There is no need to do this. This means you're setting that button on rightBarButton of NavigationBar but in your case i think you dont want to do so.
Set frame for myButton in for loop similar to imageview frame.
myButton.frame= CGRectMake(xOrigin, 0, self.myButton.frame.size.width, self.myButton.frame.size.height);

uibutton is not getting displayed

Based off your question, you'd like to add the UIButton as a subview to the UIImageView - I'm guessing in the for loop? Immediate problem I see is that the actual button is being generated outside of the for loop. I think your for loop is intended to look like this:
for (int i = 1; i <= myImagesCount; i++)
{
NSString *imageName = [NSString stringWithFormat:#"screen-%d.jpg", i];
UIImage *image = [UIImage imageNamed:imageName];
UIImageView *imageView = [[UIImageView alloc] initWithImage:image];
UIButton *button = [UIButton buttonWithType:UIButtonTypeRoundedRect];
[button addTarget:self action:#selector(buttonHandler) forControlEvents:UIControlEventAllEvents];
[button setTitle:#"point" forState:UIControlStateNormal];
button.frame = CGRectMake(0.0, 0.0, 100.0, 40.0);
button.backgroundColor = [UIColor blackColor];
CGRect rect = imageView.frame;
rect.size.height = myScrollView.frame.size.height;
NSLog(#"%d -----",self.view.frame.size.width);
rect.size.width = myScrollView.frame.size.width;
imageView.frame = rect;
imageView.tag = i;
[imageView addSubview:button];
[myScrollView addSubview:imageView];
[imageView release];
}
Try this
Declare button globally and set
[self layoutScrollImages];
[self.view bringSubViewToFront:button];
