I have a UITableViewCell that has an integrated UITextView. The goal is to make a cell that auto-expands while editing. The issue right now is that when the UITableViewController sends setEditing:YES, the UITextView scrolls and clips some of the text at the top.
I'm sure there is a better way to do this but I just don't know how...
#import "PLTextViewCell.h"
#implementation PLTextViewCell
#synthesize delegate=_delegate;
- (id)initWithStyle:(UITableViewCellStyle)style reuseIdentifier:(NSString *)reuseIdentifier {
if ((self = [super initWithStyle:style reuseIdentifier:reuseIdentifier])) {
_textView = [[UITextView alloc] initWithFrame:CGRectMake(90, 0, 200, 80)];
[_textView setEditable:NO];
[_textView setFont:[UIFont systemFontOfSize:15.0]];
[_textView setDelegate:self];
[_textView setScrollEnabled:NO];
[[self contentView] addSubview:_textView];
}
return self;
}
- (void)setEditing:(BOOL)editing animated:(BOOL)animated {
[super setEditing:editing animated:animated];
[_textView setEditable:editing];
[_textView scrollRangeToVisible:NSMakeRange(0, 1)];
[self textViewDidChange:_textView];
}
- (void)dealloc {
[_textView dealloc];
[super dealloc];
}
- (void)setTextValue:(NSString *)value {
[_textView setText:value];
[self textViewDidChange:_textView];
}
- (NSString *)textValue {
return [_textView text];
}
- (CGFloat)cellHeight {
CGSize mySize = [_textView contentSize];
NSLog(#"cell height: %f", mySize.height);
return mySize.height;
}
#pragma mark -
#pragma mark Text view delegate
- (void)textViewDidChange:(UITextView *)textView {
CGSize mySize = [_textView contentSize];
if (mySize.height > self.bounds.size.height) {
[textView scrollRectToVisible:CGRectMake(0,textView.contentSize.height-1,1,1) animated:NO];
if ([self delegate] != nil) {
[[self delegate] tableViewCellDidChangeHeight:self];
}
[textView setFrame:CGRectMake(90, 0, mySize.width, mySize.height)];
[self setNeedsLayout];
}
}
#end
Then the Table view implements a delegation method:
- (void)tableViewCellDidChangeHeight:(PLTextViewCell *)cell {
[self.tableView beginUpdates];
[self.tableView endUpdates];
}
Any ideas? Am I doing this all wrong?
Turns out that it was the UIEdgeInset combined with my textview not being tall enough. My mistake!

I create SearchBarView, a subclass of UIView, and added UISearchBar as a subview to it. After calling removeFromSuperview on SearchBarView (from searchBarSearchButtonClicked) the UISearchBar does not disappear. I tried to call removeFromSuperview on SearchBarView from where I created SearchBarView but it did not help. Any ideas why?
#import <UIKit/UIKit.h>
#interface SearchBarView : UIView <UISearchBarDelegate> {
UISearchBar *querySearchBar;
}
#end
#import "SearchBarView.h"
#implementation SearchBarView
- (id)initWithFrame:(CGRect)frame
{
self = [super initWithFrame:frame];
if (self) {
// Initialization code
querySearchBar = [[UISearchBar alloc] initWithFrame:CGRectMake(0,0,frame.size.width,44)];
querySearchBar.delegate = self;
[self addSubview:querySearchBar];
}
return self;
}
#pragma mark -
#pragma mark UISearchBarDelegate methods
- (void)searchBarSearchButtonClicked:(UISearchBar *)searchBar {
[self removeFromSuperview];
}
- (void)searchBarCancelButtonClicked:(UISearchBar *)searchBar
{
searchBar.text = #"";
[searchBar resignFirstResponder];
[searchBar setShowsCancelButton:NO animated:YES];
}
- (BOOL)searchBarShouldEndEditing:(UISearchBar *)searchBar
{
[searchBar setShowsCancelButton:NO animated:YES];
return YES;
}
- (BOOL)searchBarShouldBeginEditing:(UISearchBar *)searchBar
{
[searchBar setShowsCancelButton:YES animated:YES];
return YES;
}
#end
SearchBarView is created as follows:
SearchBarView *searchBarView = [[SearchBarView alloc] initWithFrame:CGRectMake(0, 0, 480, 300)];
UIView *rootView = [[[[UIApplication sharedApplication] delegate] window] rootViewController].view;
[rootView addSubview:searchBarView];
Your problem is
[self addSubview:querySearchBar];
If you add searchcontroller to subview, then when you do these it does not work.
[searchController.searchBar removeFromSuperview()]
self.definesPresentationContext = true
searchController.active = false
I suggest your to do
presentViewController(searchController, animated: true, completion: nil)
And try to dismiss searchController
[searchController.searchBar removeFromSuperview()]
try
[searchbar removefromsuperview];
Sounds like a question that has been answered... maybe but i have checked all of the possible solutions i believe and nothing will work for me.

I really for the life of me can not figure out why it wont display to my TableView, i have tried so many different tutorials.
any help is greatly appreciated.
You're never adding the menuList table view to your view. Add it and see if that does the trick:
// In -viewDidLoad
[self.view addSubview:menuList];
EDIT 1: Did you declare properties in your .h? These aren't visible, so it appears as if you're not creating or adding your table view to the view controller's view. However, if you are using IBOutlets, then this probably isn't the issue.
EDIT 2: From the comments below, your dataSource is nil, which is exactly why nothing is being displayed. Make sure your table view in Interface Builder has its dataSource outlet pointing to your view controller. To be double sure, delete the table view from Interface Builder and add it back again. Make sure your connections are exactly right. Also try cleaning the project and rebuilding, as well as restarting Xcode.
It looks like you are missing the required datasource method:
- (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView; {
return 1;
}
Also, it looks like you are not actually initializing your UIButton's, or anything you are adding as a subview. Are you using a nib?
I've successfully embedded a UITextView inside a UITableViewCell, and most of the table is working fine. However, when I enable editing on the UITextView and start editing, the table shifts up too far, obscuring the cursor. Is there a way to control how far the tableview scrolls? Manually scrolling the view to the cell works, but the view still scrolls up before scrolling back down and into view.
Here is an example of what I mean:
editing a UITextField - the field is neatly placed directly above the keyboard.
http://imageshack.us/photo/my-images/13/textfield.png/
editing a UITextView - the field is placed significantly above the keyboard removing the toolbar from the keyboard doesn't affect anything)
http://imageshack.us/photo/my-images/809/textview.png/
Here's all the code that is relevant to the UITextView in the UITableViewController object:
- (void)viewDidLoad
{
[super viewDidLoad];
self.navigationItem.rightBarButtonItem = self.editButtonItem;
[[NSNotificationCenter defaultCenter] addObserver: self

The TextViewCell is a subclass of UITableViewCell, and it is the cell that is giving me the problem with scrolling.Here's the implementation:
#implementation TextViewCell
#synthesize contents=_contents;
- (id)initWithStyle:(UITableViewCellStyle)style reuseIdentifier:(NSString *)reuseIdentifier
{
self = [super initWithStyle:style reuseIdentifier:reuseIdentifier];
if (self) {
_contents = [[UITextView alloc] initWithFrame:CGRectZero];
[self addSubview:_contents];
self.contents.font = [UIFont systemFontOfSize:17];
self.contents.dataDetectorTypes = UIDataDetectorTypeAll;
CGRect frame = CGRectMake(0, 0, self.window.frame.size.width, 44.0);
UIBarButtonItem *spacer = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemFlexibleSpace target:nil action:nil];
UIBarButtonItem *done = [[UIBarButtonItem alloc] initWithTitle:#"Done" style:UIBarButtonItemStyleDone target:self action:#selector(endTextViewEditing)];
UIToolbar *textViewToolbar = [[UIToolbar alloc] initWithFrame:frame];
textViewToolbar.barStyle = UIBarStyleBlackOpaque;
[textViewToolbar setItems:[NSArray arrayWithObjects:spacer, done, nil]];
self.contents.inputAccessoryView = textViewToolbar;
}
return self;
}
- (void)endTextViewEditing
{
[self.contents resignFirstResponder];
}
#define LEFT_MARGIN 15
#define TOP_MARGIN 5
- (void)layoutSubviews
{
[super layoutSubviews];
CGFloat width = self.frame.size.width - (LEFT_MARGIN *2);
CGFloat height = self.frame.size.height - (TOP_MARGIN *2);
self.contents.frame = CGRectMake(LEFT_MARGIN, TOP_MARGIN, width, height);
}
- (void)setSelected:(BOOL)selected animated:(BOOL)animated
{
//[super setSelected:selected animated:animated];
// Configure the view for the selected state
}

As it turns out, subclassing the UITableView and implementing the following fixed the problem:
- (void)setContentOffset:(CGPoint)contentOffset animated:(BOOL)animated
{
[super setContentOffset:contentOffset animated:animated];
return;
static int i = 0;
if (0 == i) {
i++;
} else {
i = 0;
[super setContentOffset:contentOffset animated:animated];
}
return;
}
Apparently the -setContentOffset:animated: message was sent 2x, and if the first one is allowed to run the second time round doesn't do it's job properly.
Does anyone have any insite as to why this would fix the problem?

Thank You
set delegate for other textfields and then remove condition if(textField == myTextField).
and
remove

I have a tableView:didSelectRowAtIndexPath: where I create a ViewController-Instance each time an item is selected. Sometimes it works fine for a long time, sometimes it crashes with a EXC_BAD_ACCESS very quickly. The debugger blames the line [super dealloc]; in the QuestionDetailViewController.
Why? I log the QuestionDetailViewController retainCount. That looks fine.

This:
- (void)viewDidDisappear:(BOOL)animated {

}
looks incredibly suspicious. Did you do [self retain]? If not, then why are you releasing? If you are, you're probably doing something wrong, because [self retain] is an incredibly rare thing to need to do.
Instead of:
[self.answerText release];
[self.titleLabel release];
[self.question release];
use:
self.answerText = nil;
self.titleLabel = nil;
self.question = nil;
or:
[answerText release]; answerText = nil;
[titleLabel release]; titleLabel = nil;
[question release]; question = nil;
