I am seeing that "Back" button title is missing when my screen title is big. I needed to show the entire title. Is there any workaround to this?
Please see attached the screenshot of navigation bar I see with long title.
Make your screen title smaller. You can take control of it by using a titleView that's a UILabel. The advantage is that you can set its size, and that it can truncate its text and/or make the text occupy two lines if the text is too big (rather than just growing, as the title does).
UIView *iv = [[UIView alloc] initWithFrame:CGRectMake(0,0,170,35)];
[iv setBackgroundColor:[UIColor whiteColor]];
_titleLabel = [[UILabel alloc] initWithFrame:CGRectMake(0, 0, 170, 35)];
_titleLabel.textAlignment = UITextAlignmentCenter;
[_titleLabel setFont:[UIFont boldSystemFontOfSize:16.0]];
[_titleLabel setBackgroundColor:[UIColor clearColor]];
[_titleLabel setTextColor:[UIColor blackColor]];
[_titleLabel setText:#""];
_titleLabel.clipsToBounds = false;
iv.clipsToBounds = false;
[iv addSubview:_titleLabel];
[self.navigationItem setTitleView:iv];
also you need
#property (strong, nonatomic) UILabel* titleLabel;

Currently I made a back Label for background and add UIButton on UILabel. It's showing in iOS 7 but in iOS 8 it's not showing . If I replace UILabel with UIView then It's working fine.
If I use UILabel in iOS 8 using this code For showing UILabel and subview UIButton
UILabel *downLabel = [[UILabel alloc]init];
downLabel.frame = CGRectMake(0, SCREEN_HEIGHT*0.92, SCREEN_WIDTH,SCREEN_HEIGHT*0.08 );
[downLabel setBackgroundColor:[UIColor colorWithRed:(66/255.f) green:(67/255.f) blue:(63/255.f) alpha:1]];
downLabel.userInteractionEnabled = YES;
[self.view addSubview:downLabel];
UIButton *downbtnobj = [[UIButton alloc]initWithFrame:CGRectMake(SCREEN_WIDTH*0.68,downLabel.frame.size.height/10,SCREEN_WIDTH*0.30,downLabel.frame.size.height/1.25)];
UIImage *btndownImage = [UIImage imageNamed:#"img 3.png"];
[downbtnobj setImage:btndownImage forState:UIControlStateNormal];
[downbtnobj addTarget:self action:#selector(bulletInButtonClicked) forControlEvents:UIControlEventTouchUpInside];
[downLabel addSubview:downbtnobj];
Now You can see only UILabel is showing but button is not showing on UILabel.
One another this If I replace UILabel by UIView then It's showing perfect.
UIView *downLabel = [[UIView alloc]init];
downLabel.frame = CGRectMake(0, SCREEN_HEIGHT*0.92, SCREEN_WIDTH,SCREEN_HEIGHT*0.08 );
[downLabel setBackgroundColor:[UIColor colorWithRed:(66/255.f) green:(67/255.f) blue:(63/255.f) alpha:1]];
downLabel.userInteractionEnabled = YES;
[self.view addSubview:downLabel];
UIButton *downbtnobj = [[UIButton alloc]initWithFrame:CGRectMake(SCREEN_WIDTH*0.68,downLabel.frame.size.height/10,SCREEN_WIDTH*0.30,downLabel.frame.size.height/1.25)];
UIImage *btndownImage = [UIImage imageNamed:#"img 3.png"];
[downbtnobj setImage:btndownImage forState:UIControlStateNormal];
[downbtnobj addTarget:self action:#selector(bulletInButtonClicked) forControlEvents:UIControlEventTouchUpInside];
[downLabel addSubview:downbtnobj];
In this code you can see I replace only UILabel by UIView. Now button is showing.
Can any help why subviews not showing on UILabel in iOS8
It's not clear what is different about labels in iOS 8, but if you call layoutIfNeeded on your label, that fixes the problem (it needs to be after you set the frame),
UILabel *downLabel = [[UILabel alloc]init];
downLabel.frame = CGRectMake(0, SCREEN_HEIGHT*0.92, SCREEN_WIDTH,SCREEN_HEIGHT*0.08 );
[downLabel layoutIfNeeded];
[downLabel setBackgroundColor:[UIColor colorWithRed:(66/255.f) green:(67/255.f) blue:(63/255.f) alpha:1]];
downLabel.userInteractionEnabled = YES;
[self.view addSubview:downLabel];
After Edit:
I also found out that if you set the text (any time after you create the label), then the button appears.
Very Simple way you need set clipsToBounds on your UILabel
downLabel.clipsToBounds = YES;
I've seen a few other examples, but I haven't seen anything that actually sticks. What I want is essentially what a tableViewHeader does. I have a tableViewController with a navigation bar. I want to put a view into place that shows some search criteria in a small bar directly below the navbar. But I need it to stick when the user swipes to view the results.
I've tried adding a UIView as a subview to the navigation bar, but it always sits at the top of the Navigation Bar, overlaying everything.
Here's what worked:
// Create a custom navigation view
_navigationView = [[UIView alloc] init];
_navigationView.backgroundColor = [UIColor whiteColor];
_navigationView.frame = CGRectMake(0.0f,
self.navigationController.navigationBar.frame.origin.y + 44.0f,
self.view.frame.size.width,
30.0f);
// Create bottom border for the custom navigation view
_navigationViewBorder = [[UIView alloc] init];
_navigationViewBorder.backgroundColor = [UIColor darkGrayColor];
_navigationViewBorder.tag = 1;
_navigationViewBorder.frame = CGRectMake(0.0f,
self.navigationController.navigationBar.frame.origin.y + 74.0f,
self.view.frame.size.width,
0.5f);
// Add labels for date, results, and the time range
_dateDisplay = [[UILabel alloc] initWithFrame:CGRectMake(10, 0, 70, 15)];
[_dateDisplay setFont:[UIFont fontWithName:#"HelveticaNeue" size:13]];
[_dateDisplay setText:#""];
_timeRangeDisplay = [[UILabel alloc] initWithFrame:CGRectMake(98, 0, 135, 15)];
[_timeRangeDisplay setFont:[UIFont fontWithName:#"HelveticaNeue-Bold" size:13]];
[_timeRangeDisplay setText:#""];
_resultsDisplay = [[UILabel alloc] initWithFrame:CGRectMake(240, 0, 80, 15)];
[_resultsDisplay setFont:[UIFont fontWithName:#"HelveticaNeue" size:13]];
[_resultsDisplay setText:#""];
[_navigationView addSubview: _dateDisplay];
[_navigationView addSubview: _timeRangeDisplay];
[_navigationView addSubview: _resultsDisplay];
// Add two views to the navigation bar
[self.navigationController.navigationBar.superview insertSubview:_navigationView belowSubview:self.navigationController.navigationBar];
[self.navigationController.navigationBar.superview insertSubview:_navigationViewBorder belowSubview:_navigationView];
Why not add the view to your viewController's view, and set up its constraints so that it sits just below the navigationBar, but above the tableView?
If it's only supposed to be there some of the time, you can animate its constraints to show/hide it.
Imagine I have dialog and size of this dialog is 200x200 and I want to present on the iPhone screen temporary (can dismiss with button).
I try it. but the view controller that I presented is replace current scene (dialog and white background border).
I want to present with custom size (200x200) at center of iPhone screen and see my content as background
I try to set dialog's background colour to clearColor and It doesn't work.
Thanks in advance.
Create your button like this,
[button addTarget:self action:#selector(ButtonFun) forControlEvents:UIControlEventTouchUpInside];
-(void)ButtonFun {
UIView *newView1 = [[UIView alloc] initWithFrame:CGRectMake(0,0,200,200)];
newView1.backgroundColor = [UIColor whiteColor];
UITextView *textView = [[UITextView alloc] initWithFrame:CGRectMake(0, 0, 200, 200)];
textView.text = #"Write your dialog";
[textView setFont:[UIFont fontWithName:#"ArialMT" size:15]];
textView.textAlignment = NSTextAlignmentCenter;
[newView1 addSubview:textView];
newView1.center = self.view.center;
[self.view addSubview:newView1];
}
To remove this UIView use UITapGestureRecognizer,or simply
[newView1 removeFromSuperview];
Does anyone have a clue on how to create a multiline navigation/top bar in iOS? I want something similar to the status line in WhatsApp (the one that displays last seen or the current status information).
Any advice would be appreciated.
I want to achieve something like in the image (Francis Whitman / last seen [...]):
By default, a UINavigationController will use the title property of the currently-displayed view controller for the title in its navigation bar. You can have it display any arbitrary view, however, by setting the titleView property of the view controller’s navigationItem property, as so:
// In your view controller’s implementation (.m) file:
- (id)initWithNibName:(NSString *)nibName
bundle:(NSStirng *)nibBundle
{
self = [super initWithNibName:nibName bundle:nibBundle];
if (self) {
UIView *myTitleView = [[UIView alloc] initWithFrame:CGRectMake(0.0f,
0.0f,
250.0f,
44.0f)];
[myView setBackgroundColor:[UIColor greenColor]];
[[self navigationItem] setTitleView:myTitleView];
}
return self;
}
UILabel *label = [[UILabel alloc]initWithFrame:CGRectMake(0, 0, self.view.frame.size.width/2, 200)];
[label setBackgroundColor:[UIColor clearColor]];
[label setTextColor:[UIColor whiteColor]];
[label setTextAlignment:NSTextAlignmentCenter];
[label setNumberOfLines:0];
[label setText:_certificate.name];
self.navigationItem.titleView = label;
Well I need to change a text on my navigation control bar to fit a movie "title" longer than the space available. I've see more code for resize the text using a label like this:
UILabel *bigLabel = [[UILabel alloc] initWithFrame:CGRectMake(0, 0, 120, 30)];
bigLabel.text = titoloSource;
bigLabel.font = [UIFont systemFontOfSize:22.0];
[bigLabel setFont:[UIFont boldSystemFontOfSize:16.0]];
[bigLabel setBackgroundColor:[UIColor clearColor]];
[bigLabel setTextColor:[UIColor whiteColor]];
[bigLabel setText:self.title];
[self.navigationController.navigationBar.topItem setTitleView:bigLabel];
self.navigationItem.titleView = bigLabel;
But I Know that the appel GUI line guide say that we can't make a small text below a certain measure. Now I've think: WHY CAN'T I MAKE an animated slider text?
So, Someone know a way to make a text animated that scroll all the "title" inside a label???
thanks
