as title, can i position the UITableViewCellEditingStyleDelete button/icon to be within the tableviewcell of a grouped tableview rather than outside of it?
An excerpt from a Matt Gallagher blog post reveals a method
This is the original code to mimic the behavior you DON'T want:
- (void)setEditing:(BOOL)editing animated:(BOOL)animated
{
[self setNeedsLayout];
}
- (void)layoutSubviews
{
[UIView beginAnimations:nil context:nil];
[UIView setAnimationBeginsFromCurrentState:YES];
[super layoutSubviews];
if (((UITableView *)self.superview).isEditing)
{
CGRect contentFrame = self.contentView.frame;
contentFrame.origin.x = EDITING_HORIZONTAL_OFFSET;
self.contentView.frame = contentFrame;
}
else
{
CGRect contentFrame = self.contentView.frame;
contentFrame.origin.x = 0;
self.contentView.frame = contentFrame;
}
[UIView commitAnimations];
}
So if we made a change, we can make it do what you do want:
- (void)setEditing:(BOOL)editing animated:(BOOL)animated
{
[self setNeedsLayout];
}
- (void)layoutSubviews
{
[UIView beginAnimations:nil context:nil];
[UIView setAnimationBeginsFromCurrentState:YES];
[super layoutSubviews];
if (((UITableView *)self.superview).isEditing)
{
//don't resize and and move your frame here
CGRect contentFrame = self.contentView.frame;
contentFrame.origin.x = 0;
self.contentView.frame = contentFrame;
}
else
{
CGRect contentFrame = self.contentView.frame;
contentFrame.origin.x = 0;
self.contentView.frame = contentFrame;
}
[UIView commitAnimations];
}
You'll proabably have to tweak this, but it is a good start.

i have an nsarray of textfields and another of textarea. I have also a toolbar with next and previous button to manage navigation between my fields. I made a fonction in textfieldDidBeginEditing and another in textfieldDidEndEditing but it didn't work correctly.
my function is :
if (textField.frame.origin.y > 180) {
[UIScrollView beginAnimations:nil context:NULL];
[UIScrollView setAnimationDelegate:self];
[UIScrollView setAnimationDuration:0.4];
[UIScrollView setAnimationBeginsFromCurrentState:YES];
CGFloat updatedY = 150;
self.scrollView.frame = CGRectMake(self.scrollView.frame.origin.x,self.scrollView.frame.origin.y - updatedY, self.scrollView.frame.size.width,
self.scrollView.frame.size.height);
[UIScrollView commitAnimations];
}
Any help will be appreciated.
I think you want Keyboard handler. The one I am using is a very good keyboard handler.
Keyboard Handler by Sukhpal Singh
This is a very good tutorial from one of my good friend and You can use this.
For using this you just have to write a single line of code.
AutoScroller * scroller=[AutoScroller addAutoScrollTo:self.scrollView isDoneToolBarNeeded:NO];
yes its done.
Please try to use this one
- (BOOL)textViewShouldBeginEditing:(UITextView *)textView
{
[UIView beginAnimations:#"" context:nil];
[UIView setAnimationDuration:.30];
[self scrollViewToCenterOfScreen:textView];
[UIView commitAnimations];
return YES;
}
- (BOOL)textFieldShouldBeginEditing:(UITextField *)textField
{
[UIView beginAnimations:#"" context:nil];
[UIView setAnimationDuration:.30];
[self scrollViewToCenterOfScreen:textField];
[UIView commitAnimations];
return YES;
}
- (void)scrollViewToCenterOfScreen:(UIView *)theView
{
CGFloat y ;
CGFloat viewCenterY = theView.center.y;
CGRect applicationFrame = [[UIScreen mainScreen] applicationFrame];
CGFloat avaliableHeight = applicationFrame.size.height - 250;
y = viewCenterY - avaliableHeight / 2.0f;
if (y < 0)
{
y = 0;
}
[scrollView setContentOffset:CGPointMake(0, y)];
}
try this code:
- (void)textFieldDidBeginEditing:(UITextField *)textField;
{
[clientscrollview setContentOffset:CGPointMake(0, textField.center.y-180) animated:YES];
}
- (BOOL)textFieldShouldReturn:(UITextField *)textField
{
[clientscrollview setContentOffset:CGPointMake(0, 0) animated:YES];
[textField resignFirstResponder];
return YES;
}
- (void)textViewDidBeginEditing:(UITextView *)textView
{
[clientscrollview setContentOffset:CGPointMake(0,textView.center.y-180) animated:YES];
}
- (void)textViewDidEndEditing:(UITextView *)textView
{
[clientscrollview resignFirstResponder];
[clientscrollview setContentOffset:CGPointMake(0,0) animated:YES];
}
HA ii ,i have two tableview in one view tableview and tab,the tab is hidden below the mainview,the user can see only tableview in the mainview,for viewing the tab the user have to click button just above the tab,when the user tap the button it drage upwards to the mainview i have done this by using this code
-(IBAction) controlPanelShowHide:(id)sender
{
CGRect frame = tab.frame;
CGRect viewframe = hideviewoftab.frame;
[UIView beginAnimations:nil context:nil];
[UIView setAnimationDuration:0.9];
if (!self.isExpanded)
{
self.isExpanded = YES;
if (frame.origin.y -=240) {
tab.frame = frame;
}
if (imageframe.origin.y -=240) {
btnShowHide.frame =imageframe;
}
if (viewframe.origin.y -=240) {
hideviewoftab.frame =viewframe;
}
} else {
self.isExpanded = NO;
if (frame.origin.y +=240) {
tab.frame = frame;
}
if (imageframe.origin.y +=240) {
btnShowHide.frame =imageframe;
}
if (viewframe.origin.y +=240) {
hideviewoftab.frame =viewframe;
}
}
[UIView commitAnimations];
}
every things work fine with this code,but i need to drag this tab with touch event ,i.e. when the user tap and hold it and drag any-ware on the screen (upwards only)> i think this is done through - (void) touchesMoved:(NSSet*)touches withEvent:(UIEvent*)eventBut how can we done this ?sorry for the very very poor english.Hope you understand my question.
thanks in advance.
EDIT:
- (void) touchesBegan:(NSSet*)touches withEvent:(UIEvent*)event
{ CGPoint pt = [[touches anyObject] locationInView:self];
[tab beginAnimations:nil context:nil];
[tab setAnimationDuration:0.1];
CGRect newFrame = tab.frame;
newFrame.origin.y += pt.y - touchingPoint.y;
newFrame.origin.x += pt.x - touchingPoint.x;
[self setFrame:newFrame];
[tab commitAnimations];
}
- (void) touchesMoved:(NSSet*)touches withEvent:(UIEvent*)event
{
CGPoint pt = [[touches anyObject] locationInView:self];
[tab beginAnimations:nil context:nil];
[tab setAnimationDuration:0.1];
CGRect newFrame = tab.frame;
newFrame.origin.y += pt.y - touchingPoint.y;
[self setFrame:newFrame];
[tab commitAnimations];
}

How can we move a view vertically upward and downwards?
Here modify the - (void) touchesMoved:(NSSet*)touches withEvent:(UIEvent*)event method with this code
- (void) touchesMoved:(NSSet*)touches withEvent:(UIEvent*)event
{
CGPoint pt = [[touches anyObject] locationInView:self];
[UITableView beginAnimations:nil context:nil];
[UITableView setAnimationDuration:0.1];
CGRect newFrame = self.frame;
newFrame.origin.y += pt.y - touchingPoint.y;
newFrame.origin.x += pt.x - touchingPoint.x;
[self setFrame:newFrame];
[UITableView commitAnimations];
}
I am trying to animate a UITextView (myTextView) that is a subview inside a UIScrollView (scrollView).
[UIView beginAnimations:nil context:NULL];
[UIView setAnimationDuration:1];
[UIView setAnimationTransition:UIViewAnimationTransitionCurlDown forView:myTextView cache:YES];
[scrollView addSubview:myTextView];
[UIView commitAnimations];
myTextView appears without animation!
What kind of animation do you want to do? If you want to fade in, for example, you have to do
[scrollView addSubview:myTextView];
myTextView.alpha = 0.0;
[UIView beginAnimations:nil context:NULL];
[UIView setAnimationDuration:1];
[UIView setAnimationTransition:UIViewAnimationTransitionCurlDown forView:myTextView cache:YES];
myTextView.alpha = 1.0;
[UIView commitAnimations];
You can change several properties (e.g.: frame, transform) to make animations.
http://www.4shared.com/dir/-PGqZEXR/zoominzoomout.html just add this file with your project and call it through this functions
here im2 is UIVIEW and i paste image on it then passing this through view didload like this
- (void)viewDidLoad {
[self loadFlowersInView:im2];
[self.view addSubview:im2];
}
now attach this function like this
- (void) loadFlowersInView: (UIView *) backdrop {
NSString *create_button = nil; // Add the flowers to random points on the screen
for (int i = 0; i < 1; i++) {
MagPicAppDelegate *appdelegate = (MagPicAppDelegate *)[[UIApplication sharedApplication] delegate];
NSString *whichFlower = appdelegate.imageName;
UIImage *stemp = [UIImage imageNamed:#"approve.png"];
DragView *dragger = [[DragView alloc] initWithImage:stemp];
dragger.userInteractionEnabled = YES;
dragger.center = CGPointMake(160.0f, 140.0f);
[im2 addSubview:dragger];
[dragger release];
}
[self.view addSubview:im2];
[im2 release];
}
i have a simple app, it consist of 2 textview, 1 uiview as a coretext subclass, and then 1 scrollview. the others part is subviews from scrollview. I use this scrollview because i need to scroll the textviews and uiview at the same time. I already scroll all of them together, but the problem is, the keyboard hiding some lines in the textview. I have to change the frame of scrollview when keyboard appear, but it still not help.
This is my code :
UIScrollView *scrollView;
UIView *viewTextView;
UITextView *lineNumberTextView;
UITextView *codeTextView;
-(void) viewWillAppear:(BOOL)animated{
[super viewWillAppear:animated];
[[NSNotificationCenter defaultCenter]
addObserver:self
selector:#selector(keyboardWillAppear:)
name:UIKeyboardWillShowNotification
object:nil];
[[NSNotificationCenter defaultCenter]
addObserver:self
selector:#selector(keyboardWillDisappear:)
name:UIKeyboardWillHideNotification
object:nil];
self.scrollView.frame = CGRectMake(0, 88, self.codeTextView.frame.size.width,
self.codeTextView.frame.size.height);
scrollView.contentSize = CGSizeMake(self.view.frame.size.width, viewTextView.frame.size.height);
[scrollView addSubview:viewTextView];
CGAffineTransform translationCoreText = CGAffineTransformMakeTranslation(60, 7);
[viewTextView setTransform:translationCoreText];
[scrollView addSubview:lineNumberTextView];
[self.scrollView setScrollEnabled:YES];
[self.codeTextView setScrollEnabled:NO];
}
-(void)keyboardWillAppear:(NSNotification *)notification {
[UIView beginAnimations:nil context:NULL];
[UIView setAnimationDuration:[[[notification userInfo]
objectForKey:UIKeyboardAnimationDurationUserInfoKey] doubleValue]];
CGRect keyboardEndingUncorrectedFrame = [[[notification userInfo]
objectForKey:UIKeyboardFrameEndUserInfoKey ] CGRectValue];
CGRect keyboardEndingFrame =
[self.view convertRect:keyboardEndingUncorrectedFrame
fromView:nil];
self.scrollView.frame = CGRectMake(0, 88, self.codeTextView.frame.size.width,
self.codeTextView.frame.size.height - keyboardEndingFrame.size.height);
[UIView commitAnimations];
}
-(void)keyboardWillDisappear:(NSNotification *) notification {
[UIView beginAnimations:nil context:NULL];
[UIView setAnimationDuration:[[[notification userInfo]
objectForKey:UIKeyboardAnimationDurationUserInfoKey] doubleValue]];
CGRect keyboardEndingUncorrectedFrame = [[[notification userInfo]
objectForKey:UIKeyboardFrameEndUserInfoKey] CGRectValue];
CGRect keyboardEndingFrame =
[self.view convertRect:keyboardEndingUncorrectedFrame
fromView:nil];
self.scrollView.frame = CGRectMake(0, 88, self.codeTextView.frame.size.width,
self.codeTextView.frame.size.height + keyboardEndingFrame.size.height);
[UIView commitAnimations];
}
can somebody help me please?
UPDATE
this is a pic from this problem :
some text still hiding by the keyboard after i do my code
UPDATE AGAIN
i think the keyboard still hiding the text because i set the textview scroll enable to be NO. is that right??
i have add this code to the keyboardwillappear method
codeBuilderSelectedRange = self.codeTextView.selectedRange;
[self.viewTextViewScroll setContentOffset:CGPointMake(0, (CGFloat)codeBuilderSelectedRange.location) animated:YES];
but it just make the textview dissappear from the view...can somebody tell the answer?

Here is some code that I have used. Basically, what we're going to do is animate the position of the view whenever a UITextField gets focus. To do this, we must make our UIViewController a delegate of our UITextFields
The first delegate method you need to implement is - (void)textFieldDidBeginEditing:(UITextField *)textField
static const CGFloat KEYBOARD_ANIMATION_DURATION = 0.3;
static const CGFloat MINIMUM_SCROLL_FRACTION = 0.2;
static const CGFloat MAXIMUM_SCROLL_FRACTION = 0.8;
static const CGFloat PORTRAIT_KEYBOARD_HEIGHT = 216;
static const CGFloat LANDSCAPE_KEYBOARD_HEIGHT = 162;
- (void)textFieldDidBeginEditing:(UITextField *)textField
{
CGRect textFieldRect = [self.view.window convertRect:textField.bounds
fromView:textField];
CGRect viewRect = [self.view.window convertRect:self.view.bounds
fromView:self.view];
CGFloat midline = textFieldRect.origin.y + 0.5
* textFieldRect.size.height;
CGFloat numerator = midline - viewRect.origin.y
- MINIMUM_SCROLL_FRACTION * viewRect.size.height;
CGFloat denominator = (MAXIMUM_SCROLL_FRACTION - MINIMUM_SCROLL_FRACTION)
* viewRect.size.height;
CGFloat heightFraction = numerator / denominator;
if (heightFraction < 0.0)
{
heightFraction = 0.0;
}
else if (heightFraction > 1.0)
{
heightFraction = 1.0;
}
UIInterfaceOrientation orientation =
[[UIApplication sharedApplication] statusBarOrientation];
if (orientation == UIInterfaceOrientationPortrait ||
orientation == UIInterfaceOrientationPortraitUpsideDown)
{
animatedDistance = floor(PORTRAIT_KEYBOARD_HEIGHT * heightFraction);
}
else
{
animatedDistance = floor(LANDSCAPE_KEYBOARD_HEIGHT * heightFraction);
}
CGRect viewFrame = self.view.frame;
viewFrame.origin.y -= animatedDistance;
[UIView beginAnimations:nil context:NULL];
[UIView setAnimationBeginsFromCurrentState:YES];
[UIView setAnimationDuration:KEYBOARD_ANIMATION_DURATION];
[self.view setFrame:viewFrame];
[UIView commitAnimations];
}
}
Now that the view has been 'pushed up' when a UITextField is selected, we want to make sure that we slide it back down when we're done:
- (void) textFieldDidEndEditing:(UITextField *)textField
{
CGRect viewFrame = self.view.frame;
viewFrame.origin.y += animatedDistance;
[UIView beginAnimations:nil context:NULL];
[UIView setAnimationBeginsFromCurrentState:YES];
[UIView setAnimationDuration:KEYBOARD_ANIMATION_DURATION];
[self.view setFrame:viewFrame];
[UIView commitAnimations];
}
This was taken from one of my favorite Cocoa blogs, Cocoa With Love. Cheezy name, but Matt's got some great posts on Objective-C development.
Specifically for UITextView (not UITextField)
you may have a look at the following tutorial: http://codingcluster.blogspot.in/2012/03/iphone-make-uitextview-move-up-when.html
i have implemented it and it is working as expected(at least for me)
I have added some table and other vies in a scrollview. scrolling in tables are working fine. But in the parent scrollview, when scrolling, a vacillating vertical scrollbars are shown, sometimes it even come to the middle of the screen. sometime show at the left side of the screen. and not limited to the vertical scrollbar region. When I set the showsVerticalScrollIndicator = NO, it is not shown. But do you know why the scrollbar is moving around.
DashboardView is a subclass of UIScrollView.
dashboard=[[DashboardView alloc] initWithFrame:fullScreenRect];
dashboard.contentSize = CGSizeMake(320,700); // must do!
dashboard.showsVerticalScrollIndicator = YES;
dashboard.bounces = YES;
self.view = dashboard;
#implementation DashboardView
- (id)initWithFrame:(CGRect)frame {
if (self = [super initWithFrame:frame]) {
// Initialization code
}
return self;
}
- (void)drawRect:(CGRect)rect {
// Drawing code
}
- (void) layoutSubviews{
NSArray *views = self.subviews;
[UIView beginAnimations:#"CollapseExpand" context:nil];
[UIView setAnimationDuration:0.5];
[UIView setAnimationBeginsFromCurrentState:YES];
[UIView setAnimationCurve:UIViewAnimationCurveEaseIn];
UIView *view = [views objectAtIndex: 0];
CGRect rect = view.frame;
for (int i = 1; i < [views count]; i++ ) {
view = [views objectAtIndex:i];
view.frame = CGRectMake(rect.origin.x, rect.origin.y + rect.size.height, view.frame.size.width, view.frame.size.height);
rect = view.frame;
}
[UIView commitAnimations];
}
Remember that scrollbars is subviews of scroll too. Exclude it from views array, before doing something with views.
Yap. that solved my problem. It seems Scrollbars are a kind of UIImageView. If anybody need it, this is my new code which works fine.
(void) layoutSubviews{
NSArray *views = self.subviews;
[UIView beginAnimations:#"CollapseExpand" context:nil];
[UIView setAnimationDuration:0.5];
[UIView setAnimationBeginsFromCurrentState:YES];
[UIView setAnimationCurve:UIViewAnimationCurveEaseIn];
//CGRect fullScreenRect=[[UIScreen mainScreen] applicationFrame];
// [self.view insertSubview:balanceView belowSubview:profileView];
UIView *view = [views objectAtIndex: 0];
CGRect rect = view.frame;
for (int i = 1; i < [views count]; i++ ) {
view = [views objectAtIndex:i];
if ([view isMemberOfClass: [UIView class] ]) {
//CFShow(view);
view.frame = CGRectMake(rect.origin.x, rect.origin.y + rect.size.height, view.frame.size.width, view.frame.size.height);
rect = view.frame;
}
}
[UIView commitAnimations];
}
