Hi I want to show a line in over view like given image.
But when i am doing this i m getting line in complete view .
My code-
UIView *lineView = [[UIView alloc] initWithFrame:CGRectMake(2,30, _MovetoSearch.frame.size.width, 1)];
lineView.backgroundColor = [UIColor whiteColor];
[_MovetoSearch addSubview:lineView];
How to make line like above image ?
When you set child view frame that time always set it using parent view frame so if in future you can change parent frame then no need to change child frame its automatically change as per parent view like I write as follow.
UIView *lineView = [[UIView alloc] initWithFrame:CGRectMake(_MovetoSearch.frame.origin.x+2,_MovetoSearch.frame.size.height-5, _MovetoSearch.frame.size.width-30, 1)];
lineView.backgroundColor = [UIColor whiteColor];
[_MovetoSearch addSubview:lineView];
I assume your searchBtn is having similar kind of code
UIButton *searchBtn = [UIButton buttonWithType:UIButtonTypeCustom];
[searchBtn setFrame:CGRectMake(_MovetoSearch.frame.size.width-32, 0, 32, 32)];
[searchBtn setImage:[UIImage imageNamed:#"search.png"] forState:UIControlStateNormal];
[searchBtn setImage:[UIImage imageNamed:#"search.png"] forState:UIControlStateHighlighted];
[searchBtn addTarget:self action:#selector(searchBtnPressed) forControlEvents:UIControlEventTouchUpInside];
For your UITextField should be
CGFloat fieldHeight = searchBtn.frame.size.height-2;
CGFloat fieldWidth = _MovetoSearch.frame.size.width - (searchBtn.frame.size.width + 4);
UITextField *textfield = [[UITextField alloc] initWithFrame:CGRectMake(2, 0, fieldWidth, fieldHeight)];
[textfield setBackgroundColor:[UIColor clearColor]];
[textfield setBorderStyle:UITextBorderStyleNone];
[textfield setNeedsDisplay];
[_MovetoSearch addSubview:textfield];
for line view
CGFloat fieldHeight = searchBtn.frame.size.height-2;
CGFloat fieldWidth = _MovetoSearch.frame.size.width - (searchBtn.frame.size.width + 4);
UIView *lineView = [[UIView alloc] initWithFrame:CGRectMake(2, fieldHeight+1, fieldWidth, 1)];
lineView.backgroundColor = [UIColor whiteColor];
[_MovetoSearch addSubview:lineView];
Hope it will work for you
I would suggest to use layer for such task and not overuse UIView.
CALayer * lineLayer = [CALayer alloc]init];
[lineLayer setFrame:CGRectMake(x,y,width,1)];
[lineLayer setBackgroundColor:[UIColor whiteColor].CGColor];
[self.view.layer addSublayer:lineLayer];

I'm setting up a subclass of UIView to roll my own UIAlertView style view. I've got everything set up properly with displaying the view, but I'm at a bit of a loss as to how to dismiss the view properly. Specifically, when a user taps on the button in the view, it needs to animate out of the main view. This is the code for the view itself:
+ (void)showCustomAlertWithTitle:(NSString *)titleString andMessage:(NSString *)messageString inView:(UIView *)view andButton1Title: (NSString *)button1Title andButton2Title: (NSString *)button2Title
{
UIWindow *window = [[[UIApplication sharedApplication] windows] lastObject];
CGRect windowFrame = window.frame;
[view setAlpha:0.5f];
UIColor *buttonColor = [UIColor colorWithRed:0/255.0f green:130/255.0f blue:216/255.0f alpha:1];
UIColor *titleColor = [UIColor colorWithRed:0/255.0f green:153/255.0f blue:102/255.0f alpha:1];
// Shade
UILabel *shadeWindow = [[UILabel alloc] initWithFrame:CGRectMake(0, 0, windowFrame.size.width, windowFrame.size.height)];
shadeWindow.backgroundColor = [UIColor blackColor];
shadeWindow.alpha = 0.50f;
// Define size and origin of alert box
float alertBoxHeight = 225;
float alertBoxWidth = 200;
float alertBoxXorigin = windowFrame.size.width / 2 - (alertBoxWidth / 2);
float alertBoxYorigin = windowFrame.size.height / 2 - (alertBoxHeight / 2);
// Initialize background
UIView *alertBackground = [[UIView alloc] initWithFrame:CGRectMake(alertBoxXorigin, alertBoxYorigin, alertBoxWidth, alertBoxHeight)];
alertBackground.layer.cornerRadius = 5.0f;
[alertBackground.layer setMasksToBounds:YES];
alertBackground.layer.backgroundColor = [UIColor whiteColor].CGColor;
// Title Label
UILabel *titleLabel = [[UILabel alloc] initWithFrame:CGRectMake(0, 0, alertBoxWidth, 40)];
titleLabel.text = titleString;
titleLabel.textAlignment = NSTextAlignmentCenter;
titleLabel.textColor = titleColor;
titleLabel.layer.backgroundColor = [UIColor colorWithRed:0 green:0 blue:0 alpha:0.05f].CGColor;
[titleLabel setFont:[UIFont fontWithName:#"AvenirNext-Bold" size:20.0]];
// Title Divider
UILabel *titleDivider = [[UILabel alloc] initWithFrame:CGRectMake(0, 40, alertBoxWidth, 1.0)];
titleDivider.backgroundColor = [UIColor grayColor];
titleDivider.alpha = 0.5f;
// Alert Message Text
UITextView *alertMessage = [[UITextView alloc] initWithFrame:CGRectMake(0, 40, alertBoxWidth, alertBoxHeight - 90)];

}
else
{
button1.frame = CGRectMake(10, alertBoxHeight - 50, (alertBoxWidth / 2) - 20, 40);
button2.frame = CGRectMake(alertBoxWidth / 2 + 10, alertBoxHeight - 50, (alertBoxWidth / 2) - 20, 40);
}
button1.layer.backgroundColor = buttonColor.CGColor;
[button1 setTitle:button1Title forState:UIControlStateNormal];
[button1.titleLabel setFont:[UIFont fontWithName:#"AvenirNext-Bold" size:15.0f]];
button1.layer.cornerRadius = 2.5f;
[button1.layer setMasksToBounds:YES];

}
When button1 is tapped, for instance, I need to have it animate the view out of the superView and remove it from the stack. I'm not sure how to handle this. Does anyone have any ideas?
To permanently remove a view, I generally use the UIView instance method removeFromSuperview. followed by a line setting the relevant variable to nil:
[myAlertView removeFromSuperview];
myAlertView = nil;
In your case then, I think you need to move the view off the screen by animating the its bounds property, then use the above couple of lines to remove any references to it.
Just found the answer here:
Dismiss view controller from #selector without creating seperate method
Had to download some custom classes but it worked:
[button1 addEventHandler:^(id sender, UIEvent *event)
{
[UIView animateWithDuration:0.25f animations:^{
[alertBackground setAlpha:0.0f];
[shadeWindow setAlpha:0.0f];
[window setAlpha:0.0f];
}];
} forControlEvent:UIControlEventTouchUpInside];
Custom classes can be found here:

i am trying to show comments list by using subview. I added subview to self.view, and i added a tableview to it in order to show comments list. now i want to enable user to add comment, i tried to add another subview to the first one with text field and button, but the view shown up and the text field and button do not. this is the code i use to do so:
GRect screenRect = [[UIScreen mainScreen] bounds];
CGFloat screenWidth = screenRect.size.width;
CGFloat screenHeight = screenRect.size.height;
// notification button
myView = [[UIView alloc] initWithFrame:CGRectMake(0, 0, screenWidth,screenHeight )];
[myView setBackgroundColor:[UIColor whiteColor]];
commentView = [[UIView alloc] initWithFrame:CGRectMake(0,screenHeight-70,screenWidth,70)];
[commentView setBackgroundColor:[UIColor redColor]];
table = [[UITableView alloc] initWithFrame:CGRectMake(0,50, screenWidth, screenHeight-100)];;
table.dataSource=self;
table.delegate=self;
UILabel *currentdate = [[UILabel alloc] initWithFrame:CGRectMake(0,10,screenWidth-40,50)];
currentdate.backgroundColor = [UIColor clearColor];
[currentdate setTextColor: [UIColor blueColor]];
[currentdate setText:#"Comments"];
currentdate.textAlignment= UITextAlignmentCenter;
currentdate.font = [UIFont fontWithName:#"Helvetica" size:20.0];
commentFeild = [[UITextField alloc] initWithFrame:CGRectMake(50,screenHeight-50,screenWidth-50,50)];
commentFeild.placeholder=#"add comment";
commentFeild.backgroundColor = [UIColor whiteColor];
[commentFeild setTextColor: [UIColor blueColor]];
commentFeild.textAlignment= UITextAlignmentRight;
commentFeild.font = [UIFont fontWithName:#"Helvetica" size:15.0];
[commentFeild.layer setCornerRadius:14.0f];
[commentFeild setTag:2030];
//[commentFeild setDelegate:self];
UIButton *doneBtn=[UIButton buttonWithType:UIButtonTypeRoundedRect];
doneBtn.frame = CGRectMake(screenWidth-45, 10,40, 30);
doneBtn.backgroundColor = [ UIColor clearColor];
[doneBtn setTitle:#"Done" forState:UIControlStateNormal];
[doneBtn setTitleColor:[UIColor blueColor] forState:UIControlStateNormal];
[doneBtn addTarget:self action:#selector(hide) forControlEvents:UIControlEventTouchUpInside];
UIButton *add=[UIButton buttonWithType:UIButtonTypeRoundedRect];
add.frame = CGRectMake(0,screenHeight-50,40,50);
add.backgroundColor = [ UIColor clearColor];
[add setTitle:#"add" forState:UIControlStateNormal];
[add setTitleColor:[UIColor blueColor] forState:UIControlStateNormal];
[add addTarget:self action:#selector(addComment) forControlEvents:UIControlEventTouchUpInside];
if(![taskObject.status isEqualToString:#"doneTask"])
{
[commentView addSubview:commentFeild];
[commentView addSubview:add];
}
[myView addSubview:doneBtn];
[myView addSubview:currentdate];
[myView addSubview:table];
[myView addSubview:commentView];
[self.view addSubview:myView];
You are adding commentFeild in commentView.
commentView = [[UIView alloc] initWithFrame:CGRectMake(0,screenHeight-70,screenWidth,70)];
Height of commentView is 70 and y position of commentField is screenHeight-50 this y position is to large as compare to commentView height.
x and y position of child view is calculated from parents x and y.
The frame of the commentField is causing the problem as the y value is very large the comment textfield is not displayed in the commentview
Correct the frame and it will show up
commentFeild = [[UITextField alloc] initWithFrame:CGRectMake(50,0,screenWidth-50,50)];
note :frame of a view is depending only to its parent view not any supers of the parent,In your case commentField's frame depends on comment view dimensions and nothing to do with any other superview
In my project I want to show a first run view when starting the app for te first time. To do this I added a UIView to my mainViewCntroller.m. To dismiss this (overlayed) view I put a button on the view called acceptButton. What code do I have to add to the Button to remove this view from the stack?
What do I do wrong?
Here's my code:
- (void) firstRun {
if (((AppDelegate*)[UIApplication sharedApplication].delegate).firstRun)
{
CGFloat height = [[UIScreen mainScreen] bounds].size.height;
CGFloat width = [[UIScreen mainScreen] bounds].size.width;
NSLog(#"%f", height);
CGRect myFrame = CGRectMake(0, 0, width, height);
UIView *myView = [[UIView alloc] initWithFrame:myFrame];
myView.backgroundColor = [UIColor scrollViewTexturedBackgroundColor];
myView.tag = 12345;
[self.view addSubview:myView];
// Create a ScrollView and a label
UIScrollView *discScroll = [[UIScrollView alloc] initWithFrame:CGRectMake(20.0f, 0.0f, self.view.frame.size.width - 20, self.view.frame.size.height -70)];
discScroll.autoresizingMask = UIViewAutoresizingFlexibleWidth | UIViewAutoresizingFlexibleHeight;
UILabel *discLabel = [[UILabel alloc] initWithFrame:CGRectMake(0,0,0,0)];
discLabel.autoresizingMask = UIViewAutoresizingFlexibleWidth | UIViewAutoresizingFlexibleHeight;
NSString *labelText = NSLocalizedString (#"InfoText",#"");
[discLabel setText:labelText];
// Tell the label to use an unlimited number of lines
[discLabel setNumberOfLines:0];
[discLabel setNumberOfLines:0];
[discLabel setBackgroundColor:[UIColor clearColor]];
[discLabel setFont:[UIFont boldSystemFontOfSize:17]];
discLabel.textColor = [UIColor colorWithRed:255 green:255 blue:255 alpha:1.0];
//[infoLabel sizeToFit];
CGSize infoLabelSize = [discLabel.text sizeWithFont:discLabel.font
constrainedToSize:CGSizeMake(discScroll.frame.size.width, 5000)
lineBreakMode:UILineBreakModeWordWrap];
discLabel.frame = CGRectMake(0, 0, infoLabelSize.width, infoLabelSize.height);
discScroll.contentSize = infoLabelSize;
[discScroll addSubview:discLabel];
[self.view addSubview:discScroll];
UIButton *acceptButton = [UIButton buttonWithType:UIButtonTypeRoundedRect];
acceptButton.frame = CGRectMake(110, [[UIScreen mainScreen] bounds].size.height - 74, 100, 44);
// position in the parent view and set the size of the button
[acceptButton setTitle:#"Click Me!" forState:UIControlStateNormal];
// add targets and actions
[acceptButton addTarget:self action:#selector(buttonClicked:) forControlEvents:UIControlEventTouchUpInside];
// add to a view
[self.view addSubview:acceptButton];
}
}
-(IBAction)buttonClicked:(id)sender
{
[[self.myView viewWithTag:12345] removeFromSuperview];
}
In my mainViewController.h is the following property:
#property (weak, nonatomic) IBOutlet UIView *myView;
EDIT I've post the complete code. Maybe something else is in the way.
Ive written it in Xcode, following Code works for me.
Ive opened a new XCode Project (Single View based), and just added following Code:
- (void)viewDidAppear:(BOOL)animated{
[super viewDidAppear:animated];
UIView *myView = [[UIView alloc] initWithFrame:CGRectMake(0, 0, self.view.frame.size.width, self.view.frame.size.height)];
myView.backgroundColor = [UIColor scrollViewTexturedBackgroundColor];
myView.tag = 12345;
[self.view addSubview:myView];
UIButton *acceptButton = [UIButton buttonWithType:UIButtonTypeRoundedRect];
acceptButton.frame = CGRectMake(0, 0, 100, 44);
[acceptButton setTitle:#"Click Me!" forState:UIControlStateNormal];
[acceptButton addTarget:self action:#selector(buttonClicked) forControlEvents:UIControlEventTouchUpInside];
[myView addSubview:acceptButton];
[myView release];
}
- (void)buttonClicked{
[[self.view viewWithTag:12345] removeFromSuperview];
}
This worked for me in iPhone Simulator.... Just this code in the MainViewController.m nothing else... Just give it a try, hope it works for you too :-)
[acceptButton addTarget:self action:#selector(buttonClicked:) forControlEvents:UIControlEventTouchUpInside];
when your method is called acceptButton, change to
[acceptButton addTarget:self action:#selector(acceptButton:) forControlEvents:UIControlEventTouchUpInside];
your target is set to buttonClicked but you are using acceptButton
[acceptButton addTarget:self action:#selector(buttonClicked:) forControlEvents:UIControlEventTouchUpInside];
-(IBAction)buttonClicked:(id)sender
{
[self.myView removeFromSuperview];
}
The problem lies with the [acceptButton addTarget:self action:#selector(buttonClicked:) line. Change buttonClicked to your method acceptButton: in that call.
[acceptButton addTarget:self action:#selector(buttonClicked:) forControlEvents:UIControlEventTouchUpInside];
The exception is clear, there is no function named "buttonClicked"
Just change the part of your code with below code;
[acceptButton addTarget:self action:#selector(acceptButton:) forControlEvents:UIControlEventTouchUpInside];
just give it a tag...
UIView *myView = [[UIView alloc] initWithFrame:myFrame];
myView.backgroundColor = [UIColor scrollViewTexturedBackgroundColor];
myView.tag = 12345;
[self.view addSubview:myView];
[myView release];
-(IBAction)acceptButton:(id)sender{
[[self.view viewWithTag:12345] removeFromSuperview];
}
Also change
action:#selector(buttonClicked:)
to
action:#selector(acceptButton:)
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;
I am designing a viewcontroller which have several button bar, each bar canbe clicked and show a content view.like:
http://i.stack.imgur.com/m5V4Q.png
When I click the buttonbar, it's frame will expand bigger, and you can see the content in it(which is a button).
First, a bar button(320*30 size) and a contentView is a set, they are subviews of listview. And several listview makes the whole view.
Second, when I click it, the list view will expand from 320*30 to 320*180, the contentview in it will expand from 300*0 to 300 * 130(20 pixel of margin). and I set the clipsToBounds of contentview to Yes to make sure the content in contentview won't show when the frame height is 0.
Now,the click can show the contentview exactly as I want. But here is a problem: I can't click the button in it, and I tried to set their userInteractionEnabled to yes . And even I set the contentview as user-defined,which I set the view's userInteractionEnabled to yes and overwrite the touchbegin function to show a alertView. Those test are failed, no reaction found. And I checked and sure that there shouldn't be any view covered it.
What's the reason might be?
The code of setup the list view is:
NSArray *array = [titleArray objectAtIndex:i];
NSString *ShenSuoTitle = [array objectAtIndex:0];
NSString *ShenSuoContent = [array objectAtIndex:1];
UIView *listView = [[UIView alloc] initWithFrame:CGRectMake(0, totalHeight, 320, ShenSuoViewHeight)];
[listView setBackgroundColor:[UIColor blackColor]];
[listView setTag:[[NSString stringWithFormat:#"%d",(i+1)] intValue]];
[self.scrollView addSubview:listView];
totalHeight = totalHeight + 1 + ShenSuoViewHeight;
UIView *titleView = [[UIView alloc] initWithFrame:CGRectMake(0, 0, 320, ShenSuoViewHeight)];
[titleView setBackgroundColor:[UIColor whiteColor]];
[titleView setTag:[[NSString stringWithFormat:#"%d1",i+1] intValue]];
[listView addSubview:titleView];
UIButton *btn = [UIButton buttonWithType:UIButtonTypeCustom];
[btn setTag:[[NSString stringWithFormat:#"%d2",i+1] intValue]];
[btn setFrame:CGRectMake(0, 0, 320, ShenSuoViewHeight)];
[btn addTarget:self action:#selector(reSetFrame:) forControlEvents:UIControlEventTouchUpInside];
[titleView addSubview:btn];
UIImageView *img = [[UIImageView alloc] initWithFrame:CGRectMake(5, 12, 30, 30)];
img.image = [UIImage imageNamed:#"list_ico.png"];
[img setTag:[[NSString stringWithFormat:#"%d3",i+1] intValue]];
[titleView addSubview:img];
NSLog(#"img:%f,%f",img.frame.origin.y,img.frame.size.height);
UILabel *labTitle = [[UILabel alloc] initWithFrame:CGRectMake(35, 15, 100, 25)];
labTitle.textColor = [UIColor blackColor];
labTitle.backgroundColor = [UIColor clearColor];
labTitle.font = [UIFont boldSystemFontOfSize:15];
labTitle.text = ShenSuoTitle;
[titleView addSubview:labTitle];
NSLog(#"labTitle:%f,%f",labTitle.frame.origin.y,labTitle.frame.size.height);
//add a label for selected
UILabel *selectedLabel = [[UILabel alloc] initWithFrame:CGRectMake(214, 14, 86, 21)];
selectedLabel.textColor = [UIColor grayColor];
//selectedLabel.alpha = 0.75;
selectedLabel.backgroundColor = [UIColor clearColor];
selectedLabel.text = #"All";
selectedLabel.font = [UIFont boldSystemFontOfSize:15];
[selectedLabel setTag:[[NSString stringWithFormat:#"%d5",i+1] intValue]];
[titleView addSubview:selectedLabel];
NSLog(#"selectedLabel:%f,%f",selectedLabel.frame.origin.y,selectedLabel.frame.size.height);
UIView *content = [[UIView alloc] initWithFrame:CGRectMake(10, 10 + ShenSuoViewHeight, 300, 0)];
content.backgroundColor = [UIColor grayColor];
UILabel *testLa = [[UILabel alloc]initWithFrame:CGRectMake(0, 0, 100, 30)];
testLa.text = #"Label";
UIButton *testBut = [UIButton buttonWithType:UIButtonTypeRoundedRect];
testBut.frame = CGRectMake(0, 40, 100, 30);
testBut.titleLabel.textColor = [UIColor greenColor];
testBut.titleLabel.text = #"Button";
content.tag = [[NSString stringWithFormat:#"%d4",i+1] intValue];
[content addSubview:testLa];
[content addSubview:testBut];
content.clipsToBounds = YES;
[testLa release];
[listView addSubview:content];
[content release];
[labTitle release];
[img release];
[titleView release];
[listView release];
the code handle the click to make the list view expands is:
UIView *titleView = (UIView *)[self.view viewWithTag:[[NSString stringWithFormat:#"%d1",i+1] intValue]];
titleView.backgroundColor = [UIColor colorWithRed:0.92 green:0.92 blue:0.92 alpha:0.9];
UIView *listView = (UIView *)[self.view viewWithTag:[[NSString stringWithFormat:#"%d",i+1] intValue]];
listView.frame = CGRectMake(0, totalHeight, 320, ShenSuoViewHeight);
totalHeight = totalHeight + 1 + 20 + 180 + ShenSuoViewHeight;
UIView *content = [self.view viewWithTag:[[NSString stringWithFormat:#"%d4",i+1] intValue]];
content.frame = CGRectMake(10, 10 + ShenSuoViewHeight, 300, 180);
UIImageView *img = (UIImageView*)[self.view viewWithTag:[[NSString stringWithFormat:#"%d3",i+1] intValue]];
img.image = [UIImage imageNamed:#"list_ico_d.png"];
I'm not sure I follow your situation exactly, and some code would be nice. To answer your question though, the reason is most likely that the touch is being intercepted elsewhere. It may also be that you just forgot to connect an action method to the button. Try using breakpoints or NSLogs to see what methods are being triggered and which aren't.
Thanks a lot. It is due to my fault. The code of expanding the bar which setting the listview's frame is wrong, it should add in the expanded height. This leads the visual is ok but the clicking not be handled.
So this problem closed.
