I am trying to add label (headerLabel) to another subview (introPadTutorial) here and it is not showing up on the screen. Can some please help me where am I making mistake?
//Header file
#property (nonatomic, retain) UIView *introPadTutorial;
//Implementation file
#synthesize introPadTutorial;
UIView *v = [_appDelegate getCurrentView];
CGRect tutorialFrame = [self getTableViewFrame];
introPadTutorial = [[UIView alloc] initWithFrame:CGRectMake(v.frame.size.width, 80, -tutorialFrame.size.width, v.frame.size.height)];
[introPadTutorial setBackgroundColor:[UIColor uberLightGray]];
[introPadTutorial setUserInteractionEnabled:YES];
UILabel *headerLabel = [[UILabel alloc] initWithFrame:CGRectMake(10, 10, 180, 180)];
[headerLabel setText:#"test test test"];
[headerLabel setBackgroundColor:[UIColor greenColor]];
[headerLabel setFont:[UIFont boldSystemFontOfSize:16.0f]];
[headerLabel setTextColor:[UIColor redColor]];
[headerLabel setShadowColor:[UIColor whiteColor]];
[headerLabel setShadowOffset:CGSizeMake(0, 1)];
[self.introPadTutorial addSubview:headerLabel];
[headerLabel release];
[v addSubview:introPadTutorial];
[introPadTutorial release];
Don't use a negative width to change the POSITION, use the origin to change the position.
Use this:
introPadTutorial = [[UIView alloc] initWithFrame:CGRectMake(v.frame.size.width - tutorialFrame.size.width, 80, tutorialFrame.size.width, v.frame.size.height)];
I think that should help make the subview actually show up.
May be your...
introPadTutorial = [[UIView alloc] initWithFrame:CGRectMake(v.frame.size.width, 80, -tutorialFrame.size.width, v.frame.size.height)];
should actually be...
introPadTutorial = [[UIView alloc] initWithFrame:CGRectMake(0, 80, tutorialFrame.size.width, v.frame.size.height)];
Is your introPadTutorial view showing up? You have a negative width in it's initWithFrame call.

I'm using the ZBar SDK to read QR codes on iPhone, however I added a button in that view. But the button is not working! Even i tap the button it doesn't go to the action method of that button. Where is the problem actually? Thanks in advance for the help.
-(UIView *)setSettingsButton
{
UIView *view=[[UIView alloc] initWithFrame:CGRectMake(0, 0, 320, 480)];
[view setBackgroundColor:[UIColor clearColor]];
UIToolbar *myToolBar = [[UIToolbar alloc] init];
UIBarButtonItem *button=[[UIBarButtonItem alloc] initWithTitle:#"Settings" style:UIBarButtonItemStyleBordered target:self action:#selector(settingsAction)];
[myToolBar setItems:[NSArray arrayWithObjects:button,nil]];
settingsLabel = [[UILabel alloc] initWithFrame:CGRectMake(20, 37, 281, 77)];
[settingsLabel setFont:[UIFont fontWithName:#"Arial-BoldMT" size:16]];
[settingsLabel setTextAlignment:UITextAlignmentCenter];
[settingsLabel setBackgroundColor:[UIColor clearColor]];
[settingsLabel setTextColor:[UIColor blueColor]];
[settingsLabel setNumberOfLines:1];
[settingsLabel setText:#"For settings scan admin QR"];
[view addSubview:settingsLabel];
settingsLabel.hidden = YES;
[myToolBar setBarStyle:UIBarStyleDefault];
CGRect toolBarFrame;
toolBarFrame = CGRectMake(0, 436, 320, 44);
[myToolBar setFrame:toolBarFrame];
[view addSubview:myToolBar];
return view;
}
-(void)settingsAction
{
settingsLabel.hidden = NO;
}
I can't see where the problem is, but if it helps, I've customized zBar camera views without any problems.
The most likely answer is that a clear views is obscuring the tool-bar view. Here's a library for debugging UIViews: https://github.com/domesticcatsoftware/DCIntrospect
I had the same problem once. It was because my view was too big. Try to change the view's size like UIView *view=[[UIView alloc] initWithFrame:CGRectMake(0, 0, 320, 380)];, you'll see if it works.
I am new to this iphone development .I am now stuck with a problem .In my application i require coverflow in which multiple labels should be shown.So for that i added an image as a sub view for view and then added the labels as a sub view for the image view.Every thing works fine for the first 7 elements But when i scroll it is showing the same elements again
I am using
https://github.com/nicklockwood/iCarousel
this to attain coverflow
- (UIView *)carousel:(iCarousel *)carousel viewForItemAtIndex:(NSUInteger)index reusingView:(ReflectionView *)view
{
UIImageView *imageView =nil;
UILabel *yourLabel=nil;
UILabel *yourLabel1=nil;
UILabel *yourLabel2=nil;
cardAvailableDataObject *singleCard=[self.cards objectAtIndex:index];
if (view == nil)
{
//set up reflection view
view = [[[ReflectionView alloc] initWithFrame:CGRectMake(0,0,200,self.view.frame.size.width/1.42)] autorelease];
imageView = [ [ UIImageView alloc ] initWithFrame:CGRectMake(0,0,200,self.view.frame.size.width/1.42)];
[view addSubview:imageView];
yourLabel = [[UILabel alloc] initWithFrame:CGRectMake(0, -5, 200, 50)];
yourLabel.textAlignment = UITextAlignmentCenter;
[yourLabel setTextColor:[UIColor colorWithRed:(38/255.f) green:(171/255.f) blue:(226/255.f) alpha:1.0f]];
[yourLabel setBackgroundColor:[UIColor clearColor]];
[yourLabel setFont:[UIFont fontWithName: #"Trebuchet MS" size: 17.0f]];
[imageView addSubview:yourLabel];
yourLabel1 = [[UILabel alloc] initWithFrame:CGRectMake(90, 40, 300, 20)];
[yourLabel1 setTextColor:[UIColor blackColor]];
[yourLabel1 setBackgroundColor:[UIColor clearColor]];
[yourLabel1 setFont:[UIFont fontWithName: #"Trebuchet MS" size: 12.0f]];
[imageView addSubview:yourLabel1];
yourLabel2 = [[UILabel alloc] initWithFrame:CGRectMake(90, 61, 300, 20)];
[yourLabel2 setTextColor:[UIColor blackColor]];
[yourLabel2 setBackgroundColor:[UIColor clearColor]];
[yourLabel2 setFont:[UIFont fontWithName: #"Trebuchet MS" size: 12.0f]];
[imageView addSubview:yourLabel2];
}
else
{
imageView = [[view subviews] lastObject];
yourLabel = [[imageView subviews] lastObject];
yourLabel1 = [[imageView subviews] lastObject];
yourLabel2= [[imageView subviews] lastObject];
}
yourLabel.text=singleCard.name;
yourLabel2.text=singleCard.companyname;
yourLabel1.text=singleCard.designation;
imageView.image=[profile objectAtIndex:index];
return view;
}
This is my code .Can any one suggest how to solve this
I'm trying to place an image (a square bracket for the focus) in the camera view of the ZBAR SDK? Can anyone please help me what needs to be done? thanks
You can set overlay of camera screen to set the cameraOverlayView property. Design a view as per your requirement and assign it:
reader.cameraOverlayView = [self CommomOverlay];
-(UIView *)CommomOverlay{
UIView *view = [[UIView alloc] initWithFrame:CGRectMake(0,0,320,480)];
UIImageView *TopBar = [[UIImageView alloc] initWithFrame:CGRectMake(0,0,320,58)];
[TopBar setImage:[UIImage imageNamed:#"topbar.png"]];
[view addSubview:TopBar];
UILabel *Toplabel = [[UILabel alloc] initWithFrame:CGRectMake(10, 9, 300, 30)];
[Toplabel setFont:[UIFont fontWithName:#"Arial-BoldMT" size:11]];
[Toplabel setTextAlignment:UITextAlignmentCenter];
[Toplabel setBackgroundColor:[UIColor clearColor]];
[Toplabel setTextColor:[UIColor colorWithRed:76/255.0 green:76/255.0 blue:76/255.0 alpha:1.0]];
[Toplabel setNumberOfLines:1];
[Toplabel setText:#"Scan now "];
[TopBar addSubview:Toplabel];
UIImageView *FrameImg = [[UIImageView alloc] initWithFrame:CGRectMake(60,150,193,170)];
[FrameImg setImage:[UIImage imageNamed:#"frame.png"]];
[view addSubview:FrameImg];
return view;
}
I have a custom made UINavigationBar (different size, background etc) that has inside a custom title view. I used this code to achieve this:
UIView * mainView = [[UIView alloc] initWithFrame:CGRectMake(0, 0, kScreenWidth, kScreenHeight)];
mainView.backgroundColor = [UIColor yellowColor];
UINavigationBar *navBar = [[UINavigationBar alloc] initWithFrame:CGRectMake(0,0,kScreenWidth,80)];
navBar.autoresizingMask = UIViewAutoresizingFlexibleWidth;
UINavigationItem *currentItem = [[UINavigationItem alloc] init];
UILabel *label = [[UILabel alloc] init];
label.font = [UIFont fontWithName:#"Helvetica-Bold" size: 30.0];
[label setBackgroundColor:[UIColor clearColor]];
[label setTextColor:[UIColor whiteColor]];
[label setText:self.title];
[label sizeToFit];
[currentItem setTitleView:label];
[label release];
[navBar pushNavigationItem:currentItem animated:NO];
[currentItem release];
[mainView addSubview:navBar];
[navBar release];
self.view = mainView;
[mainView release];
However, my problem now is that, even if the custom title view is correctly added, it's not vertically centered with the NavBar. What I am missing?
Thanks!
You can use setTitleVerticalPositionAdjustment:forBarMetrics: in iOS 5 to change the title position, it works on normal title e.g.:
CGFloat verticalOffset = -4;
[[UINavigationBar appearance] setTitleVerticalPositionAdjustment:verticalOffset forBarMetrics:UIBarMetricsDefault];
You created you UINavigationBar with a height of 80 points, when a standard UINavigationBar has 44 pts. It probably position it centred it on a 44 pts based centre...
You can try to make a UIView with a height of 80 pts and add the UILabel centred inside it. (not tested, just a guess)
i want to append two label texts(which are in different colors) in One label.any help please?
how can i do it?
you can use one UILabel with two other UILabels with their own setups as a subviews. smth like this
UILabel* mainLabel = [[UILabel alloc] initWithFrame:CGRectMake(100, 100, 120, 40)];
UILabel* firstSublabel = [[UILabel alloc] initWithFrame:CGRectMake(0, 0, 60, 40)];
[firstSublabel setText:#"asd"];
[firstSublabel setTextColor:[UIColor redColor]];
[mainLabel addSubview:firstSublabel];
[firstSublabel release];
UILabel* secondSublabel = [[UILabel alloc] initWithFrame:CGRectMake(0, 60, 60, 40)];
[secondSublabel setText:#"dfg"];
[secondSublabel setTextColor:[UIColor greenColor]];
[mainLabel addSubview:secondSublabel];
[secondSublabel release];
[self.view addSubview:mainLabel];
[mainLabel release];
Not really in a nice way.
There are some ideas for replacements in this question: Why is there no NSAttributedString on the iPhone?
