i have implemented the following code in my project!
UIImage *add_item_icon = [UIImage imageNamed:#"add_item_icon.png"];
UIImage *img = [UIImage imageNamed:#"add_button.png"];
if(headerButton != nil)
[headerButton release];
headerButton = [[UIButton alloc] init];
headerButton.frame = CGRectMake(0, 0, 320, 42);
headerButton.backgroundColor = [UIColor clearColor];
headerButton.showsTouchWhenHighlighted = YES;
[headerButton setBackgroundImage:img forState:UIControlStateNormal];
[headerButton setTitle:#"Add New Gallery" forState:UIControlStateNormal];
[headerButton setImage:add_item_icon forState:UIControlStateNormal];
headerButton.titleLabel.font = [UIFont systemFontOfSize:16];
headerButton.titleLabel.textColor = [UIColor darkGrayColor];
[headerButton addTarget:self action:#selector(headerButtonClicked:) forControlEvents:UIControlEventTouchUpInside];
//[headerButton setTitleColor:[UIColor darkGrayColor] forState:UIControlStateSelected];
My question is whenever i click the button, the color which is assigned to the title has been changed. The requirement is it should not be like that. Any one pls guide me! as early possible.
Not sure what is in your -headerButtonClicked:, but you should remove anything that looks like this in -headerButtonClicked:
headerButton.titleLabel.textColor = [UIColor darkGrayColor];

I am facing trouble unexpected issue in iphone app. for whatever reason, I compile this, I get a SIGABRT error. it happens on the:
textFieldRounded=[[UITextField alloc]initWithframe: CGRectMake(20,50,280,31)];
textFieldRounded.borderStyle=UITextBorderStyleRoundedRect;
textFieldRounded.textColor=[UIColor blackColor];
textFieldRounded.font=[UIFont systemFontOfSize:17.0];
textFieldRounded.placeholder=#"enter your name";
textFieldRounded.backgroundColor=[UIColor whiteColor];
textFieldRounded.autocorrectionType=UITextAutocorrectionTypeNo;
textFieldRounded.backgroundColor=[UIColor clearColor];
textFieldRounded.keyboardType=UIKeyboardTypeDefault;
textFieldRounded.returnKeyType=UIReturnKeyDone;
textFieldRounded.clearButtonMode=UITextFieldViewModeWhileEditing;
[self.view addSubView:textFieldRounded];
textFieldRounded.delegate=self;
UIButton *button =[UIButton buttonWithType:UIButtonTypeRoundedRect];
[button addTarget:self action:#selector(buttonPressed:)
forControlEvents:UIControlEventTouchDown];
[button setTitle:#"Button" forstate:UIControlStateNormal];
button.frame = CGRectMake(20,108,97,37);
[self.view addSubview:button];
label= [[UILabel alloc] initWithFrame:CGRectMake(40,243,240,21)];
label.backgroundColor=[UIColor clearColor];
label.textAlignment,UITextAlignmentCenter;
label.text=#"Label";
[self.view addSubview:label];
CGRect myImageRect = CGRectMake(40.0f,190.0f,240.0f,128.0f);
image= [[UIImageView alloc] initWithFrame:myImageRect];
[image setImage:[UIImage imageNamed:#"Default#2x.png"]];
image.backgroundColor=[UIColor clearColor];
image.opaque =YES;
image.alpha=0;
[self.view addSubview:image];
[image release];
}
you can Creat UITextField, UIButton or UILabel like this bellow code:-
UITextField
UITextField *textField = [[UITextField alloc] initWithFrame:CGRectMake(10, 200, 300, 40)];
textField.borderStyle = UITextBorderStyleRoundedRect;
textField.font = [UIFont systemFontOfSize:15];
textField.placeholder = #"enter text";
textField.autocorrectionType = UITextAutocorrectionTypeNo;
textField.keyboardType = UIKeyboardTypeDefault;
textField.returnKeyType = UIReturnKeyDone;
textField.clearButtonMode = UITextFieldViewModeWhileEditing;
textField.contentVerticalAlignment = UIControlContentVerticalAlignmentCenter;
textField.delegate = self;
[self.view addSubview:textField];
[textField release];
UIButton
UIButton *button = [UIButton buttonWithType:UIButtonTypeRoundedRect];
[button addTarget:self action:#selector(aMethod:) forControlEvents:UIControlEventTouchUpInside];
[button setTitle:#"UIButton" forState:UIControlStateNormal];
button.frame = CGRectMake(80.0, 210.0, 160.0, 40.0);
[view addSubview:button];
[button release];
UILabel
UILabel *headingLabel = [[UILabel alloc] initWithFrame:CGRectMake(10, 240, 300, 30)];
[self.view addSubview:headingLabel];
// Optional
headingLabel.text = #"WELCOME";
headingLabel.textColor = [UIColor orangeColor];
headingLabel.textAlignment = UITextAlignmentCenter;
headingLabel.tag = 10;
headingLabel.backgroundColor = [UIColor clearColor];
headingLabel.font = [UIFont fontWithName:#"MarkerFelt-Thin" size:14.0];
headingLabel.hidden = NO;
headingLabel.highlighted = YES;
headingLabel.highlightedTextColor = [UIColor blueColor];
headingLabel.lineBreakMode = YES;
headingLabel.numberOfLines = 0;
UIImageView
UIImageView *myImage = [[UIImageView alloc] initWithFrame:CGRectMake(0, 0, 150, 150)];
myImage.image = [UIImage imageNamed:#"myImage.png"];
[self.view addSubview:myImage];
[mymyImage release];
Hope its helps you
I want to display two buttons inside the popoverview. I am using WEPOPOVER, I am able to display one btn.
But I am not sure how to display the two buttons.
UIButton *editBtn = [UIButton buttonWithType:UIButtonTypeCustom];
[editBtn setTitle:#"EDIT ME" forState:UIControlStateNormal];
[editBtn setFrame:CGRectMake(250, 0, 100,40)];
[editBtn addTarget:self action:#selector() forControlEvents:UIControlEventTouchUpInside];
[editBtn setTitleColor:[UIColor whiteColor] forState:UIControlStateNormal];
editBtn.titleLabel.shadowOffset = CGSizeMake(0, -1);
editBtn.titleLabel.font = [UIFont boldSystemFontOfSize:20];
editBtn.backgroundColor = [UIColor blackColor];
UIButton *deleteBtn = [UIButton buttonWithType:UIButtonTypeCustom];
[deleteBtn setTitle:#"Delete ME" forState:UIControlStateNormal];
[deleteBtn setFrame:CGRectMake(250, 0, 100,40)];
[deleteBtn addTarget:self action:#selector(doSubscription) forControlEvents:UIControlEventTouchUpInside];
[deleteBtn setTitleColor:[UIColor whiteColor] forState:UIControlStateNormal];
deleteBtn.titleLabel.shadowOffset = CGSizeMake(0, -1);
deleteBtn.titleLabel.font = [UIFont boldSystemFontOfSize:20];
deleteBtn.backgroundColor = [UIColor blackColor];
// place inside a temporary view controller and add to popover
UIViewController *viewCon = [[UIViewController alloc] init];
viewCon.view = (UIView *)[NSArray arrayWithObjects:editBtn,deleteBtn, nil];
viewCon.contentSizeForViewInPopover = editBtn.frame.size; // Set the content size
navPopover = [[WEPopoverController alloc] initWithContentViewController:viewCon];
[navPopover presentPopoverFromRect:editButton.frame
inView:self.view
permittedArrowDirections:UIPopoverArrowDirectionUp | UIPopoverArrowDirectionDown
animated:YES];
You have given the same frame for both buttons. So it shows just one button.
[editBtn setFrame:CGRectMake(250, 0, 100,40)];
[deleteBtn setFrame:CGRectMake(250, 0, 100,40)];
I have got a uipickerview which will be populated when pressing a uibutton.
This uipickerview has a uitoolbar control in the top of the uipickerview.
That tool bar has got uibuttons in it.It is working fine until i do the below thing.
I want to have that uittoolbar, on top of the uikeyboard.So I have added , that uitoolbar control as InputAccessoryView.
When i did this, the uitoolbar comes with uikeyboard.that is fine.
but when i tap on the button, which has to show the uipickerview with that toolbar and also needs to resign the toolbar.
So when tap on the button, i have resigned the uikeyboard.
the uipickerview is showing but the toolbar is not visible.
I have been trying to fix this for a long time, but really facing a tough time.
Please let me know.

I have a barbuttonitem that made programmatically above a navigation controller. I want to display it's title and background also a highlighted effect when i press that bar button.
Here's the code I use :
NSArray *segmentText = [segmentTextMutable copy];
UIImage *image = [[[UIImage alloc] init] autorelease];
image = [UIImage imageNamed:#"bunga.jpg"];
_docSegmentedControl = [[UISegmentedControl alloc] initWithItems:segmentText];
_docSegmentedControl.selectedSegmentIndex = 0;
_docSegmentedControl.autoresizingMask = UIViewAutoresizingFlexibleHeight;
_docSegmentedControl.segmentedControlStyle = UISegmentedControlStyleBezeled;
[_docSegmentedControl addTarget:self action:#selector(docSegmentAction:) forControlEvents:UIControlEventValueChanged];
[_docSegmentedControl setBackgroundColor:[UIColor colorWithPatternImage:image]];
UIView *barBackground = [[UIView alloc] initWithFrame:CGRectMake(0, 0, 40, 40)];
UIButton *barButton = [UIButton buttonWithType:UIButtonTypeCustom];
UIImage *buttonImage = [UIImage imageNamed:#"button.png"];
UIImage *buttonPressedImage = [UIImage imageNamed:#"buttonPressed.png"];
[[barButton titleLabel] setFont:[UIFont boldSystemFontOfSize:12.0]];
[barButton setTitleColor:[UIColor blackColor] forState:UIControlStateNormal];
[barButton setTitleColor:[UIColor whiteColor] forState:UIControlStateHighlighted];
[barButton setTitleShadowColor:[UIColor colorWithWhite:1.0 alpha:0.7] forState:UIControlStateNormal];
[barButton setTitleShadowColor:[UIColor clearColor] forState:UIControlStateHighlighted];
[[barButton titleLabel] setShadowOffset:CGSizeMake(0.0, 1.0)];
CGRect buttonFrame = CGRectMake(0, 0, 110.0, 40);
//buttonFrame.size.width = 110.0;
//buttonFrame.size.height = buttonFrame.size.height;
[barButton setFrame:buttonFrame];
[barButton setBackgroundImage:buttonImage forState:UIControlStateNormal];
[barButton setBackgroundImage:buttonPressedImage forState:UIControlStateHighlighted];
[barButton setTitle:docSegmentFileName forState:UIControlStateNormal];
[barButton addTarget:self action:#selector(docSegmentAction:) forControlEvents:UIControlEventTouchUpInside];
[barBackground addSubview:barButton];
UIBarButtonItem *segmentItem = [[UIBarButtonItem alloc] initWithCustomView:_docSegmentedControl];
self.navItem.leftBarButtonItem = segmentItem;
self.navItem.leftBarButtonItem.title = #"";
[self.navItem.leftBarButtonItem setCustomView:barBackground];
Unfortunately, this doesn't work. Instead of showing the UIBarButtonItem, it simply vanishes (it becomes 100% transparant). When I leave out the setCustomView method, the UIBarButtonItem appears, but is not customized. How can i solve this problem?
thank's...
You are removing the UISegmentedControl from the UIBarButtonItem when you call [self.navItem.leftBarButtonItem setCustomView:barBackground];. You need to modify the UISegmentedControl not the UIBarButtonItem.
I would like to know how to create a UISlider at runtime.
You can add a slider like ever other view:
UISlider *slider = [[[UISlider alloc] initWithFrame:CGRectMake(50, 50, 100, 40)] autorelease];
[slider addTarget:self action:#selector(controlValueChanged:) forControlEvents:UIControlEventValueChanged];
slider.minimumValue = 100.00;
slider.maximumValue = 1000.00;
slider.continuous = YES;
[self.view addSubview:slider];
Use a frame that suits your needs, and add to the appropriate view (I used self.view in this example). Feel free to configure as needed. ;-)
CGRect frame = CGRectMake(50, 170, 205, kSliderHeight);
customSlider = [[UISlider alloc] initWithFrame:frame];
[customSlider addTarget:self action:#selector(sliderAction:) forControlEvents:UIControlEventValueChanged];
customSlider.backgroundColor = [UIColor clearColor];
UIImage *stetchLeftTrack = [[UIImage imageNamed:#"yellowslide.png"] stretchableImageWithLeftCapWidth:10.0 topCapHeight:0.0];
UIImage *stetchRightTrack = [[UIImage imageNamed:#"orangeslide.png"] stretchableImageWithLeftCapWidth:10.0 topCapHeight:0.0];
[customSlider setThumbImage: [UIImage imageNamed:#"slider_ball.png"] forState:UIControlStateNormal];
[customSlider setMinimumTrackImage:stetchLeftTrack forState:UIControlStateNormal];
[customSlider setMaximumTrackImage:stetchRightTrack forState:UIControlStateNormal];
