UIView alpha is disappering after UIButton is clicked - ios

I have a container UIView and a UIView with alpha 0.7f in it, also a custom UIButton with image added to that container UIView. Now whenever I click on the button a big square chunk on transparent UIView disappears and stays that way. I have no idea why this happens. Can anyone help me figure this out?
UIWindow* window = [[UIApplication sharedApplication] keyWindow];
UIView *viewTestOverViewContainer = [[UIView alloc] initWithFrame:window.bounds];
UIView *viewOverlay = [[UIView alloc] initWithFrame:viewTestOverViewContainer.frame];
viewOverlay.backgroundColor = [UIColor blackColor];
viewOverlay.alpha = 0.7;
[viewTestOverViewContainer addSubview:viewOverlay];
float x = (window.bounds.size.width/2)-98;
float y = (window.bounds.size.height/2)-98;
UIView *viewTestPicContainer = [[UIImageView alloc] initWithFrame:CGRectMake(x, y, 204, 204)];
viewTestPicContainer.backgroundColor = [UIColor whiteColor];
viewTestPicContainer.layer.cornerRadius = viewTestPicContainer.frame.size.width / 2;
viewTestPicContainer.clipsToBounds = YES;
viewTestPicContainer.backgroundColor = [UIColor whiteColor];
[viewTestPicContainer setContentMode:UIViewContentModeScaleAspectFill];
UIImageView *imgViewTestPic = [[UIImageView alloc] initWithFrame:CGRectMake(2, 2, 200, 200)];
imgViewTestPic.image = [UIImage imageNamed:#"portrait_eyes_14.jpg"];
imgViewTestPic.layer.cornerRadius = imgViewTestPic.frame.size.width / 2;
imgViewTestPic.clipsToBounds = YES;
imgViewTestPic.backgroundColor = [UIColor whiteColor];
[imgViewTestPic setContentMode:UIViewContentModeScaleAspectFill];
[viewTestPicContainer addSubview:imgViewTestPic];
[viewTestOverViewContainer addSubview:viewTestPicContainer];
UIButton *btnLeftArrow = [UIButton buttonWithType:UIButtonTypeCustom];
btnLeftArrow.frame = CGRectMake(46, 275, 12, 20);
[btnLeftArrow setImage:[UIImage imageNamed:#"popup-left-arrow"] forState:UIControlStateNormal];
[viewTestOverViewContainer addSubview:btnLeftArrow];
UIButton *btnRightArrow = [UIButton buttonWithType:UIButtonTypeCustom];
btnRightArrow.frame = CGRectMake(270, 275, 12, 20);
[btnRightArrow setImage:[UIImage imageNamed:#"popup-right-arrow"] forState:UIControlStateNormal];
[viewTestOverViewContainer addSubview:btnRightArrow];
[window addSubview:viewTestOverViewContainer];

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;
}

}
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.

UIButton's title property logs correctly but not showing up when adding button as subview

I have a UIButton that I have created, and I can successfully add it as a subview and see it on the screen. The problem is, when I try using:
[myButton setTitle:#"My Title" forState:UIControlStateNormal];
The button does not show a title when I run the app. If I NSLog the button's title after using the above method, it has in fact been set to the title that I'm passing in.
Here's my code. This is inside a UIView subclass. I realize that some of this logic might not belong in a UIView subclass but I'm just trying to get this to work as fast as possible:
// Set the view's frame, background color, corner radius
self.frame = CGRectMake(45, 200, 235, 187);
self.backgroundColor = [UIColor whiteColor];
self.layer.borderWidth = 1;
self.layer.borderColor = [UIColor grayColor].CGColor;
self.layer.cornerRadius = 5;
// Create the popup's body text label
self.popupBodyTextLabel = [[UILabel alloc]initWithFrame:CGRectMake(0, 0, 100, 150)];
self.popupBodyTextLabel.text = #"Text goes here.";
// Add text view to popup's subviews
[self addSubview:self.popupBodyTextLabel];
// Create ok button
UIButton *myButton = [[UIButton alloc]initWithFrame:CGRectMake(0, 143, 120, 44)];
myButton.backgroundColor = [UIColor whiteColor];
myButton.layer.borderWidth = 1;
myButton.layer.borderColor = [UIColor grayColor].CGColor;
[myButton setTitle:#"OK" forState:UIControlStateNormal];
// Round the button's bottom left corner
UIBezierPath *myButtonMaskPath = [UIBezierPath bezierPathWithRoundedRect:myButton.bounds byRoundingCorners:(UIRectCornerBottomLeft) cornerRadii:CGSizeMake(5.0, 5.0)];
CAShapeLayer *okButtonMaskLayer = [[CAShapeLayer alloc] init];
myButtonMaskLayer.frame = myButton.bounds;
myButtonMaskLayer.path = myButtonMaskPath.CGPath;
myButton.layer.mask = myButtonMaskLayer;
// Add selector to button
[myButton addTarget:self action:#selector(myButtonTapped:) forControlEvents:UIControlEventTouchUpInside];
// Add button to subviews
[self addSubview:myButton];
// Create the background view
self.backgroundView = [[UIView alloc]initWithFrame:CGRectMake(0, 0, [UIScreen mainScreen].bounds.size.width, [UIScreen mainScreen].bounds.size.height)];
self.backgroundView.backgroundColor = [UIColor grayColor];
self.backgroundView.alpha = 0.5f;
// Show our new views
[[[UIApplication sharedApplication] keyWindow] addSubview:self.backgroundView];
[[[UIApplication sharedApplication] keyWindow] addSubview:[MPPopupView shared]];
The code for setting button title is right, so use this code to set title color
[myButton setTitleColor:[UIColor blackColor] forState:UIControlStateNormal];

Not called button after adding in to container

I have container view, where I add some image and button.
Container view is property of UIView.
I'll add my Container View to ScrollView like this:
#property (nonatomic,strong) UIView *containerView;
..
containerView = [[UIView alloc] init];
for (int i=0;i<5;i++) {
UIImageView *whiteBack = [[UIImageView alloc] initWithFrame:CGRectMake(0, 0, 235-height, 385-height-height)];
whiteBack.center = CGPointMake(_scrollView.frame.size.width * i+_scrollView.frame.size.width/2, self.view.bounds.size.height/2-131+height);
whiteBack.backgroundColor = [UIColor darkGrayColor];
whiteBack.layer.cornerRadius = 3;
whiteBack.layer.masksToBounds = YES;
[containerView addSubview:whiteBack];
UIImageView *img = [[UIImageView alloc] initWithFrame:CGRectMake(0, 0, 228-height, 340-height-height)];
img.center = CGPointMake(_scrollView.frame.size.width * i+_scrollView.frame.size.width/2, self.view.bounds.size.height/2-150+height);
img.image = [UIImage imageNamed:[NSString stringWithFormat:#"poster0%i.jpg",i+1]];
[containerView addSubview:img];
UIButton *infoButton = [UIButton buttonWithType:UIButtonTypeCustom];
infoButton.frame = CGRectMake(233, 0, 25, 25);
infoButton.center = CGPointMake(_scrollView.frame.size.width * i+_scrollView.frame.size.width/2-100, 325-height);
[infoButton addTarget:self action:#selector(flipImage:) forControlEvents:UIControlEventTouchUpInside];
infoButton.tag = i;
infoButton.backgroundColor = [UIColor clearColor];
[infoButton setImage:[UIImage imageNamed:#"upload-50"] forState:UIControlStateNormal];
[infoButton setTintColor:[UIColor whiteColor]];
[containerView addSubview:infoButton];
}
[self.scrollView addSubview:containerView];
///
- (void) flipImage :(id) sender {
NSLog(#"infoButton pressed:%i",[sender tag]);
}
but when I pressed button nothing happens!
Your container view has a zero frame (because you just did [[UIView alloc] init];). This means that it never receives any touches because you can never hit it. This goes for the subviews too.
The reason you see the subviews is that views, by default, do not clip drawing to their bounds.
To fix, set the frame of your container view to an appropriate size for the subviews you're adding.

How to make the SubView of a UIView, placed out of UIView frame, interactive?

I have added a UIView to a View of a View Controller. Say:
CGRect paneRect = {10.0f, 10.0f, 300.0f, 50.0f};
UIView *pane = [[UIView alloc] initWithFrame:paneRect];
pane.backgroundColor = [UIColor greenColor];
pane.userInteractionEnabled = YES;
pane.clipsToBounds = NO;
[self.view addSubview:pane];
Then I've added a UIButton to pane:
CGRect testRect = {10.0f, 25.0f, pane.frame.size.width - 20.0f, 50.0f};
UIButton *test = [UIButton buttonWithType:UIButtonTypeRoundedRect];
[test setTitle:#"test" forState:UIControlStateNormal];
[test setFrame:testRect];
[pane addSubview:test];
Now half of the "test" button is within the pane and the other half is out. The upper half is interactive and responds to touches however the lower half is not.
Is it possible to make the whole "test" button interactive and touchable instead of its half?
If you really want to make these view stick with each other then you can do some thing like this
CGRect mainViewRect = {10.0f, 10.0f, 300.0f, 75.0f};
UIView *mainView = [[UIView alloc] initWithFrame:mainViewRect];
mainView.backgroundColor = [UIColor clearColor];
mainView.userInteractionEnabled = YES;
[self.view addSubview:mainView];
CGRect paneRect = {0.0f, 0.0f, 300.0f, 50.0f};
UIView *pane = [[UIView alloc] initWithFrame:paneRect];
pane.backgroundColor = [UIColor greenColor];
pane.userInteractionEnabled = YES;
pane.clipsToBounds = NO;
[mainView addSubview:pane];
CGRect testRect = {10.0f, 25.0f, pane.frame.size.width - 20.0f, 50.0f};
UIButton *test = [UIButton buttonWithType:UIButtonTypeRoundedRect];
[test setTitle:#"test" forState:UIControlStateNormal];
[test setFrame:testRect];
[mainView addSubview:test];
just do Like this Way
CGRect paneRect = {10.0f, 10.0f, 300.0f, 50.0f};
UIView *pane = [[UIView alloc] initWithFrame:paneRect];
pane.backgroundColor = [UIColor greenColor];
pane.userInteractionEnabled = NO;
pane.clipsToBounds = NO;
[self.view addSubview:pane];
CGRect testRect = {10.0f, 25.0f, pane.frame.size.width - 20.0f, 50.0f};
UIButton *test = [UIButton buttonWithType:UIButtonTypeRoundedRect];
[test setTitle:#"test" forState:UIControlStateNormal];
test.userInteractionEnabled = YES;
[test setFrame:testRect];
[pane addSubview:test];
For Action of UIButton just add
[test addTarget:self action:#selector(processButtonCLick) forControlEvents:UIControlEventTouchUpInside];
If you want to uibutton center of pane Add
test.center =pane.center;
