I am trying to set accessory view of cell which is UIButton. But it is not shown.
Here is the code
UIButton *accessory = [UIButton buttonWithType:UIButtonTypeCustom];
[accessory setImage:[UIImage imageNamed:#"plus.png"] forState:UIControlStateNormal];
[cell setAccessoryView:accessory];
Call [accessory sizeToFit]; to adjust its size according to the image.
You will need to set a frame to this accessory like this
UIButton *accessory = [UIButton buttonWithType:UIButtonTypeCustom];
[accessory setImage:[UIImage imageNamed:#"plus.png"] forState:UIControlStateNormal];
//Set the accessory frame
accessory.frame = CGRectMake(0, 0, 100, 100);
UIView* accessoryView = [[UIView alloc] initWithFrame:CGRectMake(0, 0, 24, 50)];
UIImageView* accessoryViewImage = [[UIImageView alloc] initWithImage:[UIImage imageNamed:#"arrow.png"]];
accessoryViewImage.center = CGPointMake(12, 25);
[accessoryView addSubview:accessoryViewImage];
[cell setAccessoryView:accessoryView];
[accessoryViewImage release];
[accessoryView release];
just do like this.

I am trying to develop an app with a navigation bar of custom size. (100px) In the navigation bar, I also want to include a back button. I have added both of them using the child view, but the back button is not working:
UIButton *backBtn = [UIButton buttonWithType:UIButtonTypeCustom];
UIImage *backBtnImage = [UIImage imageNamed:#"menueButton.png"];
UIImage *backBtnImagePressed = [UIImage imageNamed:#"menueButton.png"];
backBtn.exclusiveTouch = YES;
[backBtn addTarget:self action:#selector(back:) forControlEvents:UIControlEventTouchUpInside];
[backBtn setBackgroundImage:backBtnImage forState:UIControlStateNormal];
[backBtn setBackgroundImage:backBtnImagePressed forState:UIControlStateHighlighted];
backBtn.frame = CGRectMake(0, -40, 35, 32);
UIView *backButtonView = [[UIView alloc] initWithFrame:CGRectMake(0, -40, 35 , 32)];
[backButtonView addSubview:backBtn];
UIBarButtonItem *backButton = [[UIBarButtonItem alloc] initWithCustomView:backButtonView];
self.navigationItem.leftBarButtonItem = backButton;
My navigation bar size is 100 pixels tall, and when I use button position (0,0,35,32) it will work correctly. But in this case, the button is being displayed much lower than intended. What am I doing wrong?
self.btnBack = [UIButton buttonWithType:UIButtonTypeCustom];
[self.btnBack setImage:[UIImage imageNamed:#"back_active.png"] forState:UIControlStateNormal];
[self.btnBack addTarget:self action:#selector(back) forControlEvents:UIControlEventTouchUpInside];
self.btnBack.frame = CGRectMake(5, 9, 50, 30);
[self.navigationController.navigationBar addSubview:self.btnBack];
check this link also.
Update:for back button
-(void)back
{
[self.btnBack removeFromSuperview];
[self.navigationController popViewControllerAnimated animated:NO];
}
Try allocing backButtonView like this
UIView *backButtonView = [[UIView alloc] initWithFrame:CGRectMake(0, 0, 35 , 32)];
Change : orgin of view to (0,0)
Edit
Try
backBtn.frame = CGRectMake(0, 0, 35, 32);
UIView *backButtonView = [[UIView alloc] initWithFrame:CGRectMake(0, -40, 35 , 32)];
I have to create a UIBarButton on the having a globe and a text "Map" written on it.
What I have done:
I have added a UIButton with the image of the globe as backgroundImage.
Set the text on the button.
Then created a UIBarButton initWithCustomView from the above button.
Given it style as Bordered.
Result:
Now what i got is a plane button with the globe image stretched on that which is overlapping with the Text in it.
I have searched for this a lot but i only found links which show the image in background and the text above the button. Nothing like the image and text together.
Can anyone help me in creating it the way it is shown in the attachment.
Try this :
UIButton *button = [UIButton buttonWithType:UIButtonTypeCustom];
[button setTitle:#"Title" forState:UIControlStateNormal];
UIImage *butImage_on = [[UIImage imageNamed:#"closebutton_on.png"] stretchableImageWithLeftCapWidth:10 topCapHeight:10];
UIImage *butImage_over = [[UIImage imageNamed:#"closebutton_over.png"] stretchableImageWithLeftCapWidth:10 topCapHeight:10];
[button setBackgroundImage:butImage_on forState:UIControlStateNormal];
[button setBackgroundImage:butImage_over forState:UIControlStateHighlighted];
[button setImage:[UIImage imageNamed:#"globe.png"] forState:UIControlStateNormal];
[button addTarget:self action:#selector(closeProfilePage) forControlEvents:UIControlEventTouchUpInside];
button.frame = CGRectMake(0, 0, 61, 30);
[button setTitleEdgeInsets:UIEdgeInsetsMake(0, -15, 0, 2)];
[button setImageEdgeInsets:UIEdgeInsetsMake(30,
20,
0,
20)];
UIBarButtonItem *backButton = [[[UIBarButtonItem alloc] initWithCustomView:button] autorelease];
self.navigationItem.leftBarButtonItem = backButton;
Note: you need to manage insets according to your requirements.
Use image with #2x. if your graphices are high resolution. according to 640 X 960 px;:-
UIView *parentView1 = [[UIView alloc] initWithFrame:CGRectMake(0, 6,51, 44)];
UIButton *btnBack = [[UIButton alloc] initWithFrame:CGRectMake(0, 6, 51, 30)];
[btnBack setBackgroundImage:[UIImage imageNamed:#"back#2x.png"] forState:UIControlStateNormal];
[btnBack addTarget:self action:#selector(backButtonClicked) forControlEvents:UIControlEventTouchUpInside];
[parentView1 addSubview:btnBack];
[btnBack release];
UIBarButtonItem *homeBarButtomItem2 = [[UIBarButtonItem alloc] initWithCustomView:parentView1];
[parentView1 release];
[self.navigationItem setLeftBarButtonItem:homeBarButtomItem2];
[homeBarButtomItem2 release];
I want to display Image,Title name,and two left right buttons. That I have done successfully.
Here is the code:
UIView *view = [[UIView alloc]initWithFrame:CGRectMake(0, 0, 200, 100)];
UIButton *leftButton = [[UIButton alloc]init];
[leftButton setImage:[UIImage imageNamed:#"previous-arrow.png"] forState:UIControlStateNormal];
[leftButton addTarget:self action:#selector(goPrevious:) forControlEvents:UIControlEventTouchUpInside];
[leftButton setFrame:CGRectMake(20, 50, 14, 13)];
UIImageView *imageView = [[UIImageView alloc] initWithImage:[UIImage imageNamed:#"Title.png"]];
[imageView setFrame:CGRectMake(leftButton.frame.origin.x+leftButton.frame.size.width+4, 20, 50, 50)];
UILabel *nameLabel = [[UILabel alloc]initWithFrame:CGRectMake(imageView.frame.origin.x+imageView.frame.size.width+4, 30, 100, 40)];
NSString *cName = [NSString stringWithFormat:#"%#",[NameArray objectAtIndex:indexPath.section]];
[nameLabel setTextColor:[UIColor whiteColor]];
[nameLabel setBackgroundColor:[UIColor clearColor]];
[nameLabel setContentMode:UIViewContentModeScaleAspectFill];
[nameLabel setTextAlignment:UITextAlignmentLeft];
CGSize expectedLabelSize = [cName sizeWithFont:nameLabel.font
constrainedToSize:CGSizeMake(100, 40)
lineBreakMode:nameLabel.lineBreakMode];
[nameLabel setFrame:CGRectMake(imageView.frame.origin.x+imageView.frame.size.width+4, 35, expectedLabelSize.width, expectedLabelSize.height)];
nameLabel.text=cName;
UIButton *rightButton = [[UIButton alloc]init];
[rightButton setImage:[UIImage imageNamed:#"next-arrow.png"] forState:UIControlStateNormal];
[rightButton setFrame:CGRectMake(nameLabel.frame.origin.x+nameLabel.frame.size.width+4, 50, 14, 13)];
[rightButton addTarget:self action:#selector(next:) forControlEvents:UIControlEventTouchUpInside];
[view addSubview:nameLabel];
[view addSubview:imageView];
[view addSubview:leftButton];
[view addSubview:rightButton];
self.navigationItem.titleView = view;
This code is written in cellForRowAtIndexPath. The view is showing properly on navigation bar but after scrolling the tableview. Initially it is displaying on wrong coordinates.
Please Suggest.
Put this code in viewWillAppear or viewDidAppear. It's not meant to be in tableView protocol!
if ([cell.textLabel.text isEqualToString:#"Button"])
{
UIView *ButtonView = [[UIView alloc] initWithFrame:CGRectMake(100, 5, 100, 25)];
UIButton *Button = [UIButton buttonWithType:UIButtonTypeRoundedRect];
Button.frame = CGRectMake(90, 5, 90, 30);
[Button setTitle:#"PopOver" forState:UIControlStateNormal];
[ButtonView addSubview:Button];
[cell.contentView addSubview:ButtonView];
[Button addTarget:self action:#selector(showPickerPopupAction)forControlEvents:UIControlEventTouchUpInside];
Button.tag = indexPath.row;
}
- (void) showPickerPopupAction
{
NSLog( #"Button clicked." );
}
The Button's frame is almost completely outside the ButtonView's frame. If you set a backgroundColor on the ButtonView, you'll see that only the top-left corner of the button is in the ButtonView frame and only that corner will respond to touches.
Adjust the size of the ButtonView frame or the size and position of the Button frame so that the button is completely inside ButtonView.
Not sure why you need ButtonView in the first place. You could just add Button directly to the contentView.
Also, you should do [ButtonView release] after adding ButtonView to the cell.contentView.
cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:#"ButtonCell"] autorelease];
UIView *backgroundView = [[UIView alloc] initWithFrame:CGRectMake(0.0f, 0.0f, 320.0f, 44.0f)];
backgroundView.backgroundColor = [UIColor groupTableViewBackgroundColor];
cell.backgroundView = backgroundView;
UIButton *buttonLeft = [UIButton buttonWithType:UIButtonTypeRoundedRect];
[buttonLeft setTitle:#"Left" forState:UIControlStateNormal];
[buttonLeft setFrame: CGRectMake( 10.0f, 3.0f, 145.0f, 40.0f)];
[buttonLeft addTarget:self action:#selector(addToFavorites) forControlEvents:UIControlEventTouchUpInside];
UIButton *buttonRight = [UIButton buttonWithType:UIButtonTypeRoundedRect];
[buttonRight setTitle:#"Right" forState:UIControlStateNormal];
[buttonRight setFrame: CGRectMake( 165.0f, 3.0f, 145.0f, 40.0f)];
[buttonRight addTarget:self action:#selector(addToFavorites) forControlEvents:UIControlEventTouchUpInside];
[cell addSubview:buttonLeft];
[cell addSubview:buttonRight];
[backgroundView release];
-(void) addToFavorites {}
Works fine !!
I'm just wondering if anyone could help me change the position of a button label for a button that I've made with code.
Thanks a lot,
Chris
If you mean UIButton, look at UIButton's titleEdgeInsets property.
So the button label is an instance of UILabel, isn't it ?? Set the position of that label by setting the frame to it with respect to the UIButton frame.
UIButton *button = [UIButton buttonWithType:UIButtonTypeRoundedRect];
[button setFrame:CGRectMake(3, 20, w, h)];
UILabel *titleLabel = [[UILabel alloc] initWithFrame:CGRectMake(10, 20, w, h)];
[titleLabel setText:#"TITLE"];
[button addSubview:titleLabel];
[self.view addSubview:button];
[titleLabel release];
I hard coded the x and y positions of the button as well as for the label. You set some other value's and place the label in the respective position where ever you want.
If you want to set only the text position of that label you can do it like this:
UIButton *button = [UIButton buttonWithType:UIButtonTypeRoundedRect];
[button setFrame:CGRectMake(3, 20, w, h)];
UILabel *titleLabel = [[UILabel alloc] initWithFrame:CGRectMake(0, 0, w, h)];
[titleLabel setText:#"TITLE"];
[titleLabel setTextAlignment:UITextAlignmentCenter];//(UITextAlignmentRight/UITextAlignmentLeft)
[button addSubview:titleLabel];
[self.view addSubview:button];
[titleLabel release];
Hope it will help you.
UIButton *button = [UIButton buttonWithType:UIButtonTypeCustom];
button.frame = CGRectMake(0,0,50,32);
[button setBackgroundImage:[UIImage imageNamed:#"btn_back.png"] forState:UIControlStateNormal];
[button addTarget:self action:#selector(BackBtnClicked) forControlEvents:UIControlEventTouchUpInside];
UIView *backButtonView = [[UIView alloc] initWithFrame:CGRectMake(0, 0, 50, 32)];
backButtonView.bounds = CGRectOffset(backButtonView.bounds, -1, -4);
[backButtonView addSubview:button];
UIBarButtonItem *barButtonItem = [[UIBarButtonItem alloc] initWithCustomView:backButtonView];
//barButtonItem.imageInsets = UIEdgeInsetsMake(-6, 20, 30, 0);
[self.navigationItem setLeftBarButtonItem:barButtonItem];
