I am trying to make my uinavigationbar to align the same way as in the iOS6 version of my app. What I am finding is that on the iOS7 the uinavigationbar items are pulled in a bit towards the title. Also for example if you are hitting just a litle right of the uinavigationitem.rightButton, the hits are not registered, however if you hit left of it for atleast 20px you can get the hits. Can anyone help me with moving that touch area to the right as well?
Here is the code that I used to setup the button:
UIView *view = [[UIView alloc] initWithFrame:CGRectMake(0, 0, 100, 44)];
UIButton *rightButton = [UIButton buttonWithType:UIButtonTypeCustom];
rightButton.autoresizingMask = UIViewAutoresizingFlexibleHeight | UIViewAutoresizingFlexibleWidth;
rightButton.imageEdgeInsets = UIEdgeInsetsMake(0, 5, 0, 0);
rightButton.contentHorizontalAlignment = UIControlContentHorizontalAlignmentLeft;
rightButton.frame = view.bounds;
rightButton.bounds = CGRectMake(0,0,44,44);
[view addSubview:rightButton];
[rightButton setImage:[UIImage imageNamed:imageName] forState:UIControlStateNormal];
[rightButton setImage:[[UIImage imageNamed:imageName] imageWithOpacity:0.8] forState:UIControlStateHighlighted];
[rightButton addTarget:target action:sel forControlEvents:UIControlEventTouchUpInside];
navItem.rightBarButtonItem = [[UIBarButtonItem alloc] initWithCustomView:view];
Thanks,
Rajan
Use below code
UIImage *faceImage1= [UIImage imageNamed:#"slideshowarrow"];
UIButton *face1 = [UIButton buttonWithType:UIButtonTypeCustom];
face1.bounds = CGRectMake( 10, 0, faceImage1.size.width, faceImage1.size.height );
[face1 addTarget:self action:#selector(Goto_nextView) forControlEvents:UIControlEventTouchUpInside];
[face1 setImage:faceImage1 forState:UIControlStateNormal];
UIBarButtonItem *backButton1 = [[UIBarButtonItem alloc] initWithCustomView:face1];
self.navigationItem.rightBarButtonItem = backButton1;

I'm updating an app to ensure that it works as expected in iOS11. The only issue I've run into is that the navigation bar looks quite different in iOS11. The position of the elements and size is not the same between versions. I've looked at my code and i'm explicitly setting frame sizes and edge insets, why are these values are not respected in iOS11?
//-- Create Right Navigation Item Buttons
// create kabob btn
UIButton *kabobBtn = [UIButton buttonWithType:UIButtonTypeCustom];
[kabobBtn addTarget:self action:#selector(viewUsersClicked:)forControlEvents:UIControlEventTouchUpInside];
kabobBtn.clipsToBounds = YES;
[kabobBtn setImage:[UIImage imageNamed:#"KabobMenu2_0071bc_Right.png"]
forState:UIControlStateNormal];
[kabobBtn.imageView setContentMode:UIViewContentModeScaleAspectFit];
[kabobBtn setFrame:CGRectMake(0, 0, 32, 32)];
// create user profile button
UIButton *userBtn = [UIButton buttonWithType:UIButtonTypeCustom];
[userBtn setImage:[UIImage imageNamed:#"people.png"]
forState:UIControlStateNormal];
[userBtn addTarget:self action:#selector(viewUserProfileClicked:)forControlEvents:UIControlEventTouchUpInside];
[userBtn setFrame:CGRectMake(0, 0, 38, 38)];
userBtn.clipsToBounds = YES;
[userBtn.layer setCornerRadius:(38/2)];
[userBtn.layer setMasksToBounds:YES];
[userBtn.layer setBorderColor:[[UIColor blackColor]CGColor]];
[userBtn.layer setBorderWidth:1];
self.userPictureURL = [defaults objectForKey:#"userPicture"];
[userBtn setImage:[UIImage imageNamed:#"defaultUserImage.png"] forState:UIControlStateNormal];
[userBtn setContentMode:UIViewContentModeScaleAspectFill];
[userBtn setBackgroundColor:[UIColor clearColor]];
// add buttons to bar button items
UIBarButtonItem *barButton = [[UIBarButtonItem alloc] initWithCustomView:kabobBtn];
UIBarButtonItem *barButton2 = [[UIBarButtonItem alloc] initWithCustomView:userBtn];
// add bar button items to right bar button item array
self.navigationItem.rightBarButtonItems = #[barButton,barButton2];
//-- Create Left Hamburger Button
UIButton *customOpen = [UIButton buttonWithType:UIButtonTypeCustom];
[customOpen setFrame:CGRectMake(0, 0, 30, 44)];
[customOpen setImage:[UIImage imageNamed:#"hamburger.png"] forState:UIControlStateNormal];
[customOpen setImageEdgeInsets:UIEdgeInsetsMake(10, -5, 16, 10)];
UIBarButtonItem *openItem = [[UIBarButtonItem alloc] initWithCustomView:customOpen];
if(self.showHamburger){
self.navigationItem.leftBarButtonItem = openItem;
}else{
self.navigationItem.leftBarButtonItem = nil;
}
Apparently iOS 11 uses autolayout for nav bar buttons. Use auto layout constraints to set button width and height.
[userBtn.widthAnchor constraintEqualToConstant:38.f].active = YES;
[userBtn.heightAnchor constraintEqualToConstant:38.f].active = YES;
This should fix the stretching issue.
Thanks to this answer
Like image shows, I used UIBarbuttonItem as rightBarButtonItem, what I want to do is just change rightBarButton's title when I select a picture or deselect a picture, so I used code like this:
[self.rightBarButton setTitle:[NSString stringWithFormat:#"完成（%#/%#）",#(_selectedAssets.count),#(self.maxPicturesNum)]];
but the barbutton will show shin when its text changed, I try to use UIButton instead of UIBarButtonItem, and shin effect disappear indeed, but UIButton will be close to right bounds far, can you help me?
You can create UIButton and assign it to your rightBarButton
UIButton *rightButton = [[UIButton alloc] initWithFrame:someFrame];
[rightButton setBackgroundImage:someImage forState:UIControlStateNormal];
[rightButton addTarget:self action:#selector(back:) forControlEvents:UIControlEventTouchUpInside];
rightButton.titleLabel.text = [NSString stringWithFormat:#"完成（%#/%#）",#(_selectedAssets.count),#(self.maxPicturesNum)];
rightButton.titleLabel.font = someFont;
UIBarButtonItem *rightBarButtonItem = [[UIBarButtonItem alloc] initWithCustomView:rightButton];
self.rightBarButton = rightBarButtonItem;
And while updating label use rightButton.titleLabel.text
For Adjusting label use this:
- (void)setTitlePositionAdjustment:(UIOffset)adjustment
forBarMetrics:(UIBarMetrics)barMetrics
Finally,I do like this:
- (void)loadRightButtonItem{
UIButton *button = [UIButton buttonWithType:UIButtonTypeCustom];
button.frame = CGRectMake(30, 0, 120, 40);
button.contentHorizontalAlignment = UIControlContentHorizontalAlignmentRight;
[button setTitle:#"完成（0/9）" forState:UIControlStateNormal];
button.tintColor = [UIColor whiteColor];
[button setTitleShadowColor:[UIColor whiteColor] forState:UIControlStateHighlighted];
// [button setTitleColor:[self.buttonFolder titleColorForState:UIControlStateHighlighted] forState:UIControlStateHighlighted];
[button addTarget:self action:#selector(onFinishClicked:) forControlEvents:UIControlEventTouchUpInside];
UIView *view = [[UIView alloc] initWithFrame:CGRectMake(0, 0, 135, 40)];
UIBarButtonItem *item = [[UIBarButtonItem alloc] initWithCustomView:view];
[view addSubview:button];
self.navigationItem.rightBarButtonItem = item;
_rightBarButton = button;
}
It cancel the shin effect.
thanks to #RoHaN,your idea did great inspired me.
backButton = [UIButton buttonWithType:UIButtonTypeCustom];
[backButton addTarget:self action:#selector(gotoAmphorasViewController) forControlEvents:UIControlEventTouchUpInside];
[backButton setFrame:CGRectMake(0.0f,0.0f, 44,44)];
The problem i am facing is that though the button dimensions are44*44, wherever i tap anywhere around it, the the button action is fired.
Please try the bellow code : its working properly
- (void)viewDidLoad {
[super viewDidLoad];
UIImage *buttonImage = [UIImage imageNamed:#"back.png"];
UIButton *button = [UIButton buttonWithType:UIButtonTypeCustom];
[button setImage:buttonImage forState:UIControlStateNormal];
button.frame = CGRectMake(0, 0, buttonImage.size.width, buttonImage.size.height);
[button addTarget:self action:#selector(back) forControlEvents:UIControlEventTouchUpInside];
UIBarButtonItem *customBarItem = [[UIBarButtonItem alloc] initWithCustomView:button];
self.navigationItem.leftBarButtonItem = customBarItem;
[customBarItem release];
}
-(void)back {
[self.navigationController popViewControllerAnimated:YES];
}
Its not a bug. It is a default behaviour. In iPhone, for navigation bar buttons the touch detection is little more expanded rather than its frame. Just have a look on any other application. Everywhere the button get fired if we tap nearer but outside its frame.
It's the intended behaviour, if you really want to limit the area of the touch, you can wrap the button inside a UIView:
UIView *buttonContainer = [[UIView alloc] initWithFrame:CGRectMake(0, 0, 44, 44)];
[buttonContainer addSubview:button];
_barButton = [[UIBarButtonItem alloc] initWithCustomView:buttonContainer];
I am trying to use following code in my viewDidLoad method to add two UIBarButtonItems to the left side of the navigation bar, but only the second button is shown:
//nav bar buttons
UIView* leftButtonView = [[UIView alloc]initWithFrame:CGRectMake(0, 0, 40, 40)];
UIButton* leftButton = [UIButton buttonWithType:UIButtonTypeSystem];
leftButton.backgroundColor = [UIColor clearColor];
leftButton.frame = leftButtonView.frame;
[leftButton setImage:[UIImage imageNamed:#"toTop"] forState:UIControlStateNormal];
[leftButton setTitle:#"" forState:UIControlStateNormal];
leftButton.tintColor = [UIColor redColor]; //Your desired color.
leftButton.autoresizesSubviews = YES;
leftButton.autoresizingMask = UIViewAutoresizingFlexibleWidth | UIViewAutoresizingFlexibleLeftMargin;
[leftButton addTarget:self action:#selector(toTop:) forControlEvents:UIControlEventTouchUpInside];
UIView* leftButtonView2 = [[UIView alloc]initWithFrame:CGRectMake(85, 0, 40, 40)];
UIButton* leftButton2 = [UIButton buttonWithType:UIButtonTypeSystem];
leftButton2.backgroundColor = [UIColor clearColor];
leftButton2.frame = leftButtonView.frame;
[leftButton2 setImage:[UIImage imageNamed:#"toSectionTop"] forState:UIControlStateNormal];
[leftButton2 setTitle:#"" forState:UIControlStateNormal];
leftButton2.tintColor = [UIColor redColor]; //Your desired color.
leftButton2.autoresizesSubviews = YES;
leftButton2.autoresizingMask = UIViewAutoresizingFlexibleWidth | UIViewAutoresizingFlexibleLeftMargin;
[leftButton2 addTarget:self action:#selector(toTop:) forControlEvents:UIControlEventTouchUpInside];
[leftButtonView addSubview:leftButton];
[leftButtonView2 addSubview:leftButton2];
UIBarButtonItem* leftBarButton = [[UIBarButtonItem alloc]initWithCustomView:leftButtonView];
UIBarButtonItem* leftBarButton2 = [[UIBarButtonItem alloc]initWithCustomView:leftButtonView2];
self.navigationItem.leftBarButtonItem = leftBarButton;
self.navigationItem.leftBarButtonItem = leftBarButton2;
Any help is welcome. Thank you
You're setting the same property twice so the second setting replaces the first. Try:
self.navigationItem.leftBarButtonItems = #[ leftBarButton, leftBarButton2 ];
Note this is setting leftBarButtonItem*s*, which takes an array of bar buttons.
Also, you shouldn't need the container views, they add no value. Buttons are views so you can use them directly. Setting the frame origin of the view may also cause you issues.
Update - One Possible Solution
Based on answer given by Alexander Merchi in this post (UIBarButtonItem Custom view in UINavigationBar), a solution is found. But still don't know how to change the position of the image properly.
UIButton *btn = [UIButton buttonWithType:UIButtonTypeCustom];
[btn setFrame:CGRectMake(0, 0, 28.0f, 28.0f)]; // 28 points is the width or height of the button image
[btn setBackgroundImage:[UIImage imageNamed:#"button.png"] forState:UIControlStateNormal];
[btn addTarget:self action:#selector(onClickMenuButton) forControlEvents:UIControlEventTouchUpInside];
btnMenu = [[UIBarButtonItem alloc] initWithCustomView:btn];
Original Post
In iOS 6, the goal is like this:
while current result is like this:
My code is
btnMenu = [[UIBarButtonItem alloc] initWithImage:[UIImage imageNamed:#"button.png"]
style:UIBarButtonItemStylePlain
target:self
action:#selector(onClickMenuButton)];
button.png is this the white circle with white three bars inside and a tranparent background.
UIButton *rightButton = [UIButton buttonWithType:UIButtonTypeCustom];
rightButton.frame = CGRectMake(0, 0, 30, 30);
[rightButton setImage:[UIImage imageNamed:#"Button-normal"] forState:UIControlStateNormal];
[rightButton setImage:[UIImage imageNamed:#"logout-hover"] forState:UIControlStateHighlighted];
[rightButton addTarget:self action:#selector(logOut) forControlEvents:UIControlEventTouchUpInside];
UIBarButtonItem *rightBarButtonItem = [[UIBarButtonItem alloc] initWithCustomView:rightButton];
self.navigationItem.leftBarButtonItem = rightBarButtonItem;
I am accomplishing it by
UIImageView *uView = [[UIImageView alloc] initWithImage:[UIImage imageNamed:#"btn_back_ontouch_scr11.png"]];
UIButton *leftButton = [UIButton buttonWithType:UIButtonTypeCustom];
leftButton.bounds = CGRectMake( 0, 0, uView.frame.size.width, uView.frame.size.height );
[leftButton setImage:uView.image forState:UIControlStateHighlighted];
[leftButton setImage:[UIImage imageNamed:#"btn_back_normal_scr11.png"]forState:UIControlStateNormal];
[leftButton addTarget:self.navigationController action:#selector(popViewControllerAnimated:) forControlEvents:UIControlEventTouchUpInside];
UIBarButtonItem *aButton = [[UIBarButtonItem alloc] initWithCustomView:leftButton];
self.scrollView.indicatorStyle=UIScrollViewIndicatorStyleWhite;
self.navigationItem.leftBarButtonItem = aButton;
self.navigationItem.hidesBackButton = YES;
This should work.
