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!

I am creating a UIPickerView, UIToolbar, UIBarButtonItem and UIButton programmatically. I'v set the custom picker as an inputView of a textView and everything works without problem except the Done button.
Does anyone have any idea of what the problem is?
The code I've used is:
// initialize picker
CGRect cgRect =[[UIScreen mainScreen] bounds];
CGSize cgSize = cgRect.size;
_picker = [[UIPickerView alloc] init];
_picker.frame=CGRectMake(0, 0, cgSize.width, cgSize.height);
_picker.showsSelectionIndicator = YES;
_picker.delegate = self;
// toolbar of picker
UIToolbar* toolbar = [[UIToolbar alloc] init];
toolbar.frame=CGRectMake(0, 0, cgSize.width, 35);
toolbar.barStyle = UIBarStyleBlackTranslucent;
UIBarButtonItem *flexibleSpaceLeft = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemFlexibleSpace target:nil action:nil];
UIButton *customButton = [[UIButton alloc]initWithFrame:CGRectMake(0, 0, 60, 33)];
[customButton setTitle:#"Done" forState:UIControlStateNormal];
[customButton addTarget:self action:#selector(doneClicked:) forControlEvents:UIControlEventTouchUpInside];
UIBarButtonItem *barCustomButton =[[UIBarButtonItem alloc] initWithCustomView:customButton];
NSMutableArray * arr = [NSMutableArray arrayWithObjects:flexibleSpaceLeft, barCustomButton, nil];
[toolbar setItems:arr animated:YES];
self.txtTeam.inputView = _picker;
[_picker addSubview:toolbar];
And the doneClicked method is;
-(void)doneClicked
{
NSLog(#"Done button clicked.");
[self.txtTeam resignFirstResponder];
}
But the Done button is not clickable.
UIButton *customButton = [UIButton buttonWithType:UIButtonTypeCustom];
[customButton setFrame:CGRectMake(0, 0, 30, 60)];
[customButton setTitle:#"Done" forState:UIControlStateNormal];
[customButton addTarget:self action:#selector(doneClicked:) forControlEvents:UIControlEventTouchUpInside];
UIBarButtonItem *barCustomButton =[[UIBarButtonItem alloc] initWithCustomView:customButton];
Try Like this..
You have set the selector for the button to call doneClicked: but the method is called doneClicked. Remove the : from the end of the method name in the selector and it should work.
Change your code to below:-
UIButton *customButton = [UIButton buttonWithType:UIButtonTypeCustom];
customButton.frame = CGRectMake(0, 0, 60, 33);
[customButton addTarget:self action:#selector(doneClicked) forControlEvents:UIControlEventTouchUpInside];
customButton.showsTouchWhenHighlighted = YES;
[customButton setTitle:#"Done" forState:UIControlStateNormal];
customButton.imageEdgeInsets = UIEdgeInsetsMake(10, 10, 10, 10);
UIBarButtonItem *barCustomButton =[[UIBarButtonItem alloc] initWithCustomView:customButton];
just comment the below your code and modify above
// UIButton *customButton = [[UIButton alloc]initWithFrame:CGRectMake(0, 0, 60, 33)];
// [customButton setTitle:#"Done" forState:UIControlStateNormal];
//[customButton addTarget:self action:#selector(doneClicked:) forControlEvents:UIControlEventTouchUpInside];
// UIBarButtonItem *barCustomButton =[[UIBarButtonItem alloc] initWithCustomView:customButton];
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 want to bring a view to my view controller with a little animation.
some thing like the Facebook app.
i use this code to bring the uiview to the screen and i want to know how i can do it with little animation:
self.tmpView = [[UIView alloc] initWithFrame:CGRectMake(20, 20, 280, 330)];
self.tmpView.backgroundColor = [UIColor yellowColor];
UIImage *tmpImg = [UIImage imageNamed:#"d.png"];
UIImageView *tmpImgView = [[UIImageView alloc] initWithFrame:CGRectMake(10, 10, 100, 100)];
tmpImgView.image = tmpImg;
UIButton *returnBTN = [[UIButton buttonWithType:UIButtonTypeRoundedRect] retain];
returnBTN.frame = CGRectMake(10, 110, 100, 25);
returnBTN.backgroundColor = [UIColor clearColor];
[returnBTN setTitle:#"חזור" forState:UIControlStateNormal];
[returnBTN addTarget:self action:#selector(backPressed) forControlEvents:UIControlEventTouchUpInside];
UIButton *orderBTN = [[UIButton buttonWithType:UIButtonTypeRoundedRect] retain];
[orderBTN setTag:tag];
orderBTN.frame = CGRectMake(130, 110, 100, 25);
orderBTN.backgroundColor = [UIColor clearColor];
[orderBTN setTitle:#"הזמן" forState:UIControlStateNormal];
[orderBTN addTarget:self action:#selector(orderPressed:) forControlEvents:UIControlEventTouchUpInside];
[self.tmpView addSubview:tmpImgView];
[self.tmpView addSubview:returnBTN];
[self.tmpView addSubview:orderBTN];
[self.view addSubview:self.tmpView];
[UIView transitionFromView:viewToMoveOut toView:viewToMoveIn duration:timeOfDuration options:(option1 | option2 | ...) completion:^(BOOL finished){
if (finished){
// code when animation finished.
}
}];
How about this:
addSubview animation
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];
