I have added FbLike button which provided in SDK 3.19.Its working fine but I need to change the image and text of button.I have googled but did not find anything.
Yes, this is possible the same way you would change the default FBLoginView button.
loginView.frame = CGRectMake(320/2 - 93/2, self.view.frame.size.height -200, 93, 93);
for (id loginObject in loginView.subviews)
{
if ([loginObject isKindOfClass:[UIButton class]])
{
UIButton * loginButton = loginObject;
UIImage *loginImage = [UIImage imageNamed:#"YOUR_IMAGE_HERE"];
loginButton.alpha = 0.7;
[loginButton setBackgroundImage:loginImage forState:UIControlStateNormal];
[loginButton setBackgroundImage:nil forState:UIControlStateSelected];
[loginButton setBackgroundImage:nil forState:UIControlStateHighlighted];
[loginButton sizeToFit];
}
if ([loginObject isKindOfClass:[UILabel class]])
{
UILabel * loginLabel = loginObject;
loginLabel.text = #"";
loginLabel.frame = CGRectMake(0, 0, 0, 0);
}
}

I have created a custom Facebook Login Button. Everything works but I can't get the image to center (top/bottom) in the button. The image it self is but when I create this button the image is lower.
//FB Button (Uses Facebook SDK)
self.fbLoginButton = [[FBLoginView alloc] init];
for (id loginObject in self.fbLoginButton.subviews)
{
if ([loginObject isKindOfClass:[UIButton class]])
{
UIButton * loginButton = loginObject;
UIImage *loginImage = [UIImage imageNamed:#"Facebook_White.png"];
[loginButton setBackgroundImage:loginImage forState:UIControlStateNormal];
[loginButton setBackgroundImage:nil forState:UIControlStateSelected];
[loginButton setBackgroundImage:nil forState:UIControlStateHighlighted];
[loginButton setTitle:nil forState:UIControlStateNormal];
[loginButton setTitle:nil forState:UIControlStateSelected];
[loginButton setTitle:nil forState:UIControlStateHighlighted];
}
if ([loginObject isKindOfClass:[UILabel class]])
{
UILabel * loginLabel = loginObject;
loginLabel.text = #"";
loginLabel.frame = CGRectMake(0, 0, 0, 0);
}
}
self.fbLoginButton.delegate = self;
self.fbLoginButton.readPermissions = #[#"public_profile", #"email"];
[[self.fbLoginButton layer]setBorderWidth:2.0];
[[self.fbLoginButton layer]setBorderColor:UIColorFromRGB(0xbbffd6).CGColor];
[buttonsArray addObject:self.fbLoginButton];
Here is what it looks like compared to the Twitter Button:
Here is the actual .png (the text is white so you can't see it unless it is against a background:
Any suggestions?
After playing around, this is what worked for me. Had to hard code the fbLoginView.frame and the loginButton.frame.
//FB Button (Uses Facebook SDK)
self.fbLoginView = [[FBLoginView alloc] init];
self.fbLoginView.readPermissions = #[#"public_profile", #"email"];
self.fbLoginView.frame = CGRectMake(0, 0, 35, 35);
[[self.fbLoginView layer]setBorderWidth:2.0];
[[self.fbLoginView layer]setBorderColor:UIColorFromRGB(0xbbffd6).CGColor];
for (id loginObject in self.fbLoginView.subviews)
{
if ([loginObject isKindOfClass:[UIButton class]])
{
UIButton * loginButton = loginObject;
loginButton.frame = CGRectMake(self.fbLoginView.frame.origin.x, self.fbLoginView.frame.origin.y, 35, 35);
UIImage *loginImage = [UIImage imageNamed:#"Facebook_White.png"];
[loginButton setBackgroundImage:loginImage forState:UIControlStateNormal];
[loginButton setBackgroundImage:nil forState:UIControlStateSelected];
[loginButton setBackgroundImage:nil forState:UIControlStateHighlighted];
}
if ([loginObject isKindOfClass:[UILabel class]])
{
UILabel * loginLabel = loginObject;
loginLabel.text = #"";
loginLabel.frame = CGRectMake(0, 0, 0, 0);
}
}
self.fbLoginView.delegate = self;
[socialButtonsArray addObject:self.fbLoginView];
I am created two buttons that are right next to each other to mimic a segmented control. I am doing this to customize the appearance beyond what the UIKit allows. I decided to use the selected property to keep a button pressed. I have two images that one for each state normal and selected.
The problem is that when I select a button, the button highlights and turns dark, because of the hightlight state. I decided to use the selected image for the highlight state too, but it flashes, any ideas or suggestions.
- (void)leftSegmentPressed:(id)sender
{
if ([sender isSelected]) {
[sender setSelected:NO];
}
else {
[sender setSelected:YES];
}
}
For the "selected" button, disable it and manually switch the image for the state.
- (void) viewDidLoad
{
[rightSegmentButton setImage:[UIImage imageNamed:#"unselected.png"] forState:UIControlStateNormal];
[rightSegmentButton setImage:[UIImage imageNamed:#"selected.png"] forState:UIControlStateDisabled];
[leftSegmentButton setImage:[UIImage imageNamed:#"unselected.png"] forState:UIControlStateNormal];
[leftSegmentButton setImage:[UIImage imageNamed:#"selected.png"] forState:UIControlStateDisabled];
}
- (void)leftSegmentPressed:(id)sender
{
sender.enabled = NO;
rightSegmentButton.enabled = YES;
}
- (void)rightSegmentPressed:(id)sender
{
sender.enabled = NO;
leftSegmentButton.enabled = YES;
}
Check whether the image you given is in your Bundle or check image name you given is in lower case or not. Then write like
[button1 setImage:[UIImage imageNamed:#"normal1.png"] forState:UIControlStateNormal];
[button1 setImage:[UIImage imageNamed:#"selected1.png"] forState:UIControlStateSelected];
[button2 setImage:[UIImage imageNamed:#"normal2.png"] forState:UIControlStateNormal];
[button2 setImage:[UIImage imageNamed:#"selected2.png"] forState:UIControlStateSelected];
button1.tag = 1;
button2.tag = 2;
[button1 addTarget:self action:#selector(buttonSelected:) forControlEvents:UIControlEventTouchUpInside]
[button2 addTarget:self action:#selector(buttonSelected:) forControlEvents:UIControlEventTouchUpInside]
in your button event method
-(void)buttonSelected:(id)sender {
if([sender tag] == 1) {
button1.selected = YES;
button2.selected = NO;
} else {
button1.selected = NO;
button2.selected = YES;
}
}
[button setAdjustsImageWhenHighlighted:NO];
This will prevent the flicker.
UIButton *yourButton1 = [[UIButton buttonWithType:UIButtonTypeRoundedRect] retain];
yourButton1.frame = CGRectMake(110.0, 360.0, 100.0, 30.0);
[yourButton1 setTitle:#"Left" forState:UIControlStateNormal];
yourButton.backgroundColor = [UIColor clearColor];
yourButton1.tag = 1;
[yourButton1 setTitleColor:[UIColor whiteColor] forState:UIControlStateNormal ];
UIImage *buttonImageNormal = [UIImage imageNamed:#"yourNormalImage.png"];// set normal image
UIImage *strechableButtonImageNormal = [buttonImageNormal stretchableImageWithLeftCapWidth:12 topCapHeight:0];
[yourButton1 setBackgroundImage:strechableButtonImageNormal forState:UIControlStateNormal];
UIImage *buttonImagePressed = [UIImage imageNamed:#"yourSelectedImage.png"];// set selected image
UIImage *strechableButtonImagePressed = [buttonImagePressed stretchableImageWithLeftCapWidth:12 topCapHeight:0];
[yourButton1 setBackgroundImage:strechableButtonImagePressed forState:UIControlStateHighlighted];
[yourButton1 addTarget:self action:#selector(leftSegmentPressed:) forControlEvents:UIControlEventTouchUpInside];
[self.view addSubview:yourButton1];
do same for another second button.
and in action method set bellow code..
- (void)leftSegmentPressed:(id)sender
{
UIButton *btnTemp = (UIBUtton *)sender;
if (btnTemp.tag == 1) {
[yourButton1 setSelected:YES];
[yourButton2 setSelected:NO];
}
else {
[yourButton1 setSelected:NO];
[yourButton2 setSelected:YES];
}
}
I am using iCarousel as shownh here with carousel type Liner Carousel and implemented delete functionalty .I am able to delete the image in carousel and when I attempt to delete any other iomage in the visible screen It is moved to carousel frame and deleted.
I need to delete the image from its original position.
- (void)loadView {
[super loadView];
self.view.backgroundColor = [UIColor blackColor];
carousel = [[iCarousel alloc] initWithFrame:CGRectMake(-130,300, 320, 100)];
carousel.dataSource = self;
carousel.delegate=self;
carousel.type = iCarouselTypeLinear;
carousel.scrollEnabled=YES;
imageView=[[UIImageView alloc]initWithFrame:CGRectMake(60, 50, 200, 200)];
[self.view addSubview:imageView];
}
- (UIView *)carousel:(iCarousel *)carousel viewForItemAtIndex:(NSUInteger)index reusingView:(UIView *)view
{
UIImage *image = [imagesArray objectAtIndex:index];
UIButton *button =[UIButton buttonWithType:UIButtonTypeCustom];
button.frame = CGRectMake(0,0, 60, 60);
[button setBackgroundImage:image forState:UIControlStateNormal];
[button setTitleColor:[UIColor blackColor] forState:UIControlStateNormal];
button.titleLabel.font = [button.titleLabel.font fontWithSize:50];
[button addTarget:self action:#selector(buttonTapped:) forControlEvents:UIControlEventTouchUpInside];
button.tag=index;
NSLog(#"tag is %d",button.tag);
UIButton *deleteButton=[UIButton buttonWithType:UIButtonTypeRoundedRect];
deleteButton.frame= CGRectMake(50, -5, 20 ,20);
UIImage *img = [UIImage imageNamed:#"close.png"];
[deleteButton setImage:img forState:UIControlStateNormal];
[deleteButton addTarget:self action:#selector(deleteButtonClicked:) forControlEvents:UIControlEventTouchUpInside];
[button addSubview:deleteButton];
return button;
}
-(void)deleteButtonClicked:(int )sender
{
NSInteger currentIndex = carousel.currentItemIndex;
[carousel removeItemAtIndex:currentIndex animated:YES];
}
Please help me out.
You shouldn't delete the item at the carousel.currentItemIndex because that is not the item corresponding to the button you clicked, that's just the currently centred item in the carousel.
To get the correct item index for the button you clicked, do this:
-(void)deleteButtonClicked:(id)sender
{
//get the index of the item view containing the button that was clicked
NSInteger index = [carousel indexOfItemViewOrSubview:sender];
//update the data model (always do this first)
[imagesArray removeObjectAtIndex:index];
//remove item from carousel
[carousel removeItemAtIndex:index animated:YES];
}
Try this:
NSInteger index = carousel.currentItemIndex;
[carousel removeItemAtIndex:index animated:YES];
[imagesArray removeObjectAtIndex:index];
add this also:
- (void)awakeFromNib
{
if (self) {
//set up carousel data
wrap = NO;
}
}
or make your
carousel.type = iCarouselTypeCustom;
to
carousel.type = iCarouselTypeLinear;
then implement this: [carousel reloadData];
My button is not responding to touch events, please find the code snippet as below.
I have added UIButton to UIView and set the UIView to UITableView's footerview.
Please let me know and thanks.
CGRect tblViewFrame = CGRectMake(self.view.bounds.origin.x, self.view.bounds.origin.y, self.view.bounds.size.width, 300);
self.tblViewSettings = [[[UITableView alloc]initWithFrame:tblViewFrame style:UITableViewStyleGrouped]autorelease];
self.tblViewSettings.backgroundColor = [UIColor clearColor];
self.tblViewSettings.showsVerticalScrollIndicator = FALSE;
self.tblViewSettings.delegate = self;
self.tblViewSettings.dataSource = self;
self.tblViewSettings.scrollEnabled = YES;
// Set the background color
self.view.backgroundColor = [UIColor clearColor];
UIView *buttonView = [[[UIView alloc]initWithFrame:CGRectMake(10,10, 320, 60)]autorelease];
self.signoutButton = [UIButton buttonWithType:UIButtonTypeRoundedRect];
self.signoutButton.frame = CGRectMake(10,10, 300, 40);
UIImage *image = [[UIImage imageNamed:#"btn-large1.png"] stretchableImageWithLeftCapWidth:22 topCapHeight:0];
NSString *strSignOut = NSLocalizedString(#"Sign Out", #"SignOut Button");
[self.signoutButton setTitle:strSignOut forState:UIControlStateNormal];
[self.signoutButton setTitleColor:[UIColor whiteColor] forState:UIControlStateNormal];
self.signoutButton.titleLabel.shadowOffset = CGSizeMake(0, -1);
[self.signoutButton setBackgroundImage:image forState:UIControlStateNormal];
self.signoutButton.titleLabel.font = [UIFont boldSystemFontOfSize:20.0];
[self.signoutButton addTarget:self action:#selector(signOutBtnTapped:) forControlEvents:UIControlEventTouchUpInside];
buttonView.backgroundColor = [UIColor clearColor];
[buttonView addSubview:self.signoutButton];
buttonView.userInteractionEnabled = YES;
//[self.view addSubview:buttonView];
self.tblViewSettings.tableFooterView = buttonView;
self.tblViewSettings.tableFooterView.userInteractionEnabled = YES;
[self.view addSubview:self.tblViewSettings];
-(IBAction)signOutBtnTapped:(id)sender{
}
I have looked at your code and applied it to my project. actually it works. i did not change anything from your code. i guess u must check out the frames of table view and the bottom view as everything else is working fine.
Try capturing the event for UIControlEventTouchDown instead of UIControlEventTouchUpInside in
[self.signoutButton addTarget:self action:#selector(signOutBtnTapped:) forControlEvents: UIControlEventTouchUpInside];
Everything else seems OK.
for Adding button in Footer view Section
- (UIView *)tableView:(UITableView *)tableView viewForFooterInSection:(NSInteger)section
{
UIView* customView;
customView = [[UIView alloc] initWithFrame:CGRectMake(0.0, 0.0, 320.0, 60.0)];
UIButton *Login_Btn = [UIButton buttonWithType:UIButtonTypeCustom];
[Login_Btn setImage:[UIImage imageNamed:#"btn_login.png"] forState:UIControlStateNormal];
Login_Btn.frame = kiPhoneButtonFrame;
[customView addSubview:Login_Btn];
[Login_Btn addTarget:self
action:#selector(Login_Btn_Clicked:)
forControlEvents:UIControlEventTouchUpInside];
return customView;
}
And Button Click Method
-(IBAction)Login_Btn_Clicked:(id)sender
{
// Code for button CLick which you want to do.
}
I tried to add reflection to my icarousel. Firstly my code was like this and it was working wright.
- (UIView *)carousel:(iCarousel *)carousel viewForItemAtIndex:(NSUInteger)index reusingView:(UIView *)view
{
UIButton* button = (UIButton *)view;
if (button == nil)
{
//no button available to recycle, so create new one
UIImage *image = [arrKitapKapaklari objectAtIndex:index];
button = [UIButton buttonWithType:UIButtonTypeCustom];
button.frame = CGRectMake(0.0f, 0.0f, image.size.width, image.size.height);
[button setTitleColor:[UIColor clearColor] forState:UIControlStateNormal];
[button setBackgroundImage:image forState:UIControlStateNormal];
button.titleLabel.font = [button.titleLabel.font fontWithSize:50];
[button addTarget:self action:#selector(buttonTapped:) forControlEvents:UIControlEventTouchUpInside];
}
//set button label
[button setTitle:[NSString stringWithFormat:#"%i", index] forState:UIControlStateNormal];
return button;
}
After changing, my code became like this:
- (UIView *)carousel:(iCarousel *)carousel viewForItemAtIndex:(NSUInteger)index reusingView:(ReflectionView *)view
{
UIButton* button = nil;
if (button == nil)
{
view = [[[ReflectionView alloc] initWithFrame:CGRectMake(0.0f, 0.0f, 150.0f, 200.0f)] autorelease];
//no button available to recycle, so create new one
UIImage *image = [arrKitapKapaklari objectAtIndex:index];
button = [UIButton buttonWithType:UIButtonTypeCustom];
button.frame = CGRectMake(0.0f, 0.0f, image.size.width, image.size.height);
[button setTitleColor:[UIColor clearColor] forState:UIControlStateNormal];
[button setBackgroundImage:image forState:UIControlStateNormal];
button.titleLabel.font = [button.titleLabel.font fontWithSize:50];
[button addTarget:self action:#selector(buttonTapped:) forControlEvents:UIControlEventTouchUpInside];
[view addSubview:button];
}
//set button label
[button setTitle:[NSString stringWithFormat:#"%i", index] forState:UIControlStateNormal];
[view update];
return view;
}
Reflection appears. But the problem is when i move the carousel view, images not flowing correctly. Sometimes another carousel view appears.
Do you have any idea what causes that?
Code should be:
- (UIView *)carousel:(iCarousel *)carousel viewForItemAtIndex:(NSUInteger)index reusingView:(ReflectionView *)view
{
UIButton* button = nil;
if (view == nil)
{
//no view available to recycle, so create new one
view = [[[ReflectionView alloc] initWithFrame:CGRectMake(0.0f, 0.0f, 150.0f, 200.0f)] autorelease];
button = [UIButton buttonWithType:UIButtonTypeCustom];
button.frame = view.bounds;
[button setTitleColor:[UIColor clearColor] forState:UIControlStateNormal];
button.titleLabel.font = [button.titleLabel.font fontWithSize:50];
[button addTarget:self action:#selector(buttonTapped:) forControlEvents:UIControlEventTouchUpInside];
button.tag = 99;
[view addSubview:button];
}
else
{
button = (UIButton *)[view viewWithTag:99];
}
//set button label
[button setTitle:[NSString stringWithFormat:#"%i", index] forState:UIControlStateNormal];
UIImage *image = [arrKitapKapaklari objectAtIndex:index];
[button setBackgroundImage:image forState:UIControlStateNormal];
[view update];
return view;
}
I use images with reflection built in them... don't need to do anything in code that way.. :p
I found my mistake. I am loading images here:
-(void) getImagesWithThread{
NSAutoreleasePool *pool;
pool = [[NSAutoreleasePool alloc] init];
//for(int i=0;i<bookCount;i++){
for(int i=0;i<bookCount;i++){
NSData * imageData = [[NSData alloc] initWithContentsOfURL: [NSURL URLWithString: [arrBookImages objectAtIndex:i]]];
UIImage *image = [[UIImage imageWithData: imageData] retain];
image = [self scaleToSize:CGSizeMake(140, 200) withImage:image];
if(image!=nil) [arrBookImages replaceObjectAtIndex:i withObject:image];
[image release]; }
[carousel reloadData];
[pool drain];
}
When i performed this in background it didn't reload correctly. İf i perform normally, it works. But i want to load them in a thread. I mean first i want to set images and replace them images from url. but i want them to appear one by one. Do you have any idea?
