I am using https://github.com/CEWendel/SWTableViewCell library to my project.
Certain situation I need to disable the particular button action of swipe cell.
I cannot find any property in their class file. If anyone crossed this, give me answer.
Here I have attaced my swipe options image:
For ex
: I want to disable the share button action.
Let's assume your share button is in the leftButtonsArray. In the method:
- (void)swipeableTableViewCell:(SWTableViewCell *)cell scrollingToState:(SWCellState)state
{
//case:left buttons opened
UIButton *shareButton = leftButtonsArray[theIndexOfTheShareButton];
shareButton.enabled = NO;
}
#karthikeyan You can hide the button for a particular row in tableview by the following code:
- (void)updateRightUtilityButtons:(NSArray *)rightUtilityButtons WithButtonWidth:(CGFloat) width {
_rightUtilityButtons = rightUtilityButtons;
[self.rightUtilityButtonsView updateUtilityButtons:rightUtilityButtons WithButtonWidth:width];
[self.rightUtilityButtonsView layoutIfNeeded];
[self layoutIfNeeded];
}
Add/update this methods to SWTableViewCell.m class, where rightUtilityButtons is an array of buttons you need to display for the particular row.
In case if you want to disable just user interaction you can achieve while adding button into array, just disable user interaction for that button by shareButton.userInteration = NO and then add to array and then pass the array to the method defined above. By this you can be sure that button is disabled.
But please provide the sample code that you have worked so that can update your code directly.
In case if you still didn't get revert back I'll give you the working code directly here.

I want to set a recent search history dropdown for UISearchbar . I have implemented a dropdown programatically using a UITableView
Logic:
How i have implemented is by setting a UITableView right below the UISearchBar and on click on the UISearchBar it will pop up .
Am initially hiding that tableview in viewdidload and in
-(BOOL)searchBarShouldBeginEditing:(UISearchBar *)searchBar am unhiding the tableview .
Iam facing too many problems with this :
1. The return button is not enabled when the searchbartext is empty .In that case if i have to cancel/hide the table view again i have to depend on tapgestures .
2. Clicking on the searchbartext again won't trigger any of its delegates. The only time it triggers the delegates on click on the searchbartext is when click on it for the first time then it calls -(BOOL)searchBarShouldBeginEditing:(UISearchBar *)searchBar
Do u guys have any other solution / way to implement this feature in a much better way than this ??
Do we have any custom made UISearchBar recent history dropdowns ??
I have searched for a custom UISearchBar recent history dropdown in cocoacontrols,code4app and cocoapods for this no hope dint find any .
Please help me with this .
For your first issue, you can add a category on UISearchBar something like this and this shall always enable your return button on keyboard when tapped on UISearchBar
#implementation UISearchBar (MyAddition)
- (void)alwaysEnableSearch {
// Loop around subviews of UISearchBar
NSMutableSet *viewsToCheck = [NSMutableSet setWithArray:[self subviews]];
while ([viewsToCheck count] > 0) {
UIView *searchBarSubview = [viewsToCheck anyObject];
[viewsToCheck addObjectsFromArray:searchBarSubview.subviews];
[viewsToCheck removeObject:searchBarSubview];
if ([searchBarSubview conformsToProtocol:#protocol(UITextInputTraits)]) {
#try {
// Force return key to be enabled
[(UITextField *)searchBarSubview setEnablesReturnKeyAutomatically:NO];
}
#catch (NSException *iException) {
}
}
}
}
For second issue, why don't you use shouldChangeTextInRange: delegate method which gets called for each entered character.
As a side note, this SO thread has a sample code to do this. This may help you.
Good luck!
I am re-writing the possible steps as per your recent clarification.
keep a flag/boolean to monitor tableview is hidden or not.
in the UISearchBar Delegate method check the serachbar's text field's [obj isFirstResponder] method.
a. if firstResponder =yes --> Show the histroy tableview OR Vice versa.After show/hide is accomplished call below method on UISearchBar' textfield.
*[searchbarobj.textfield resignFirstResponder];*
b. if firstResponder = No---> Don't do anything. leave the method.
I have an app with a UITableView of results in a center column, and a little search bar at the top. I want to dynamically add/remove a button that says "reset search" and pin it to the top of the view.
There are a couple ways to go about it, and I'm worried that they both look ugly or hacky to me. To wit:
Add the button in the storyboard editor, and show/hide it in code. The trouble is I've already got a bunch of views specified this way in the storyboard, and so positioning/selecting them is a huge pain since they overlap each other.
Add the button in code. Except now my UI is specified in two places: the stuff that's in the storyboard, and the additional modifications that take place in the code.
What's the standard way of doing something like this? And how can I prevent my storyboards from becoming a big mess when I've got buttons/dialogs/etc. that need to be dynamically shown/hidden?
Well my first answer is to not use storyboards in the first place. However, I understand that's not helpful in this case.
If I were you, I would do option 2. It's a one off for this single button and it has a specific use case. It doesn't hurt to specify it in code. The following is for the
.h
#property (nonatomic, strong) UIButton *resetButton;
And
.m
//I'm guessing you're using a VC, so I'd put this in viewDidLoad
self.resetButton = [[UIButton alloc]initWithFrame:YOUR FRAME];
self.resetButton.alpha = 0.0;
//any other styling
[self.view addSubview:self.resetButton];
self.resetButton addTarget:self action:#selector(onReset) forControlEvents:UIControlEventTouchUpInside];
//and then add these three methods
- (void)onReset {
//called when reset button is tapped
}
- (void)showResetButton {
[UIView animateWithDuration:.3 animations:^{
self.resetButton.alpha = 1.0;
}];
}
- (void)hideResetButton {
[UIView animateWithDuration:.3 animations:^{
self.resetButton.alpha = 0.0;
}];
}
I don't know if I have understood, but if you want to hide an object with an action, you can do so :
- (IBAction)myaction:(id)sender
{
self.object1.hidden = false ;
self.object2.hidden = true ;
self.object3.hidden = false ;
}
Both ways are perfect, I personally prefer the Storyboard one because it lets you arrange the button more easily and it's easier to add constraints for auto-layout(if needed) in Interface Builder than in code.
For your second question: If your storyboard is cluttered and views are all over the place, I would suggest that you select your views from the side bar, rather thank trying to click on them. Also, if you want to move the selected view, adjust the coordinates in the Utilities panel instead of dragging it with the mouse.
I have a UITableview as a contact list in which there are a lot of users. It has a thumbnail photo and profile details on each row. I want to make it like when clicking on thumbnail, it goes another page for photo and when clicking on the rest of the space it goes to somewhere else. By using table view delegate I know which row is clicked and pass data, like user id to a new ViewController. But can I know which row when the thumbnail is clicked?
I am using the tag to find the view from cell, like
UIImageView *thumbnailView = (UIImageView *) [cell viewWithTag:1];
I think I cannot label the row index by tag.
You can add gesture to thumbnail image and get events on it. Need to set tag for thumb image as per indexPath.row.
Add following code in you in cell datasource method (cellForRowIndexPath:) :
cell.YOURIMGVIEW.userInteractionEnabled = YES;
cell.YOURIMGVIEW.tag = indexPath.row;
UITapGestureRecognizer *clickable = [[UITapGestureRecognizer alloc] initWithTarget:self action:#selector(imageClicked:)];
clickable.numberOfTapsRequired = 1;
[cell.YOURIMGVIEW addGestureRecognizer:clickable];
[clickable release];
And also used below method :
-(void)imageClicked:(id)sender
{
UITapGestureRecognizer *gesture = (UITapGestureRecognizer *) sender;
NSLog(#"image tag is = %d", gesture.view.tag);
////////
You custome come goes Here !!!!!!!!!!!!!!
///////
}
You can use the photo as accessory view. Or use a UIButton with the photograph as background and set the action accordingly. (e.g. call a method on the view controller which then performs the push or segue. Doing so you will have to pass some data to the view controller indicating which row was actually clicked in. The number of the row can be used or you can set the tag of the button with some numeric id.)
Go the Easy way because doing it hard-way won't grant you a president award, right ?
Instead of UIImageView take a UIButton and set the Image on UIButton instance.
Set Button tag as the indexPath.row so that when you retrieve it you know which row is clicked. You can also sort it the other way but it seems quiet handy.
Add target into the button to a custom function. [ btnObj addTarget ...... ]
tyepcast you sender to a UIButton and receive the tag (indexpath.row)
You can remove all gesture recognizers and buttons in tableviewcell, and in your controller, you can implement below delegate;
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath;
To make this method triggered, you need to set tableview delegate as your controller, either via code as below, or using storyboard.
- (void)viewDidLoad {
self.tableview.delegate = self;
}
By doing this, it won't matter which item you clicked in your cell, delegate method will be called always.
I hope this helps.
I am new to iOS programming and using iOS 6. I see that, using XCode I can CTRL+drag action and outlets for button sand text field but not for the storyboard. I want to do some action when user clicks on the storyboard (taps away from the text field).
Here is my code:
- (IBAction)editingEnded:(UITextField *)sender {
NSLog(#"%#", #"in editingEnded");
[sender resignFirstResponder];
}
- (IBAction)buttonSelected:(UIButton *)sender {
if(_firstClick) {
[_textField resignFirstResponder];
}
}
I guess, you asked me to implement something like editingEnded? This is my delegate for editing did end action (how can I confirm this, there is no such annotation/attribute attached to this method?). However, this method alone didn't work. When i added the 2nd method buttonSelected as a delegate for another button on the story board, then editingEnded is also called due to [_textField resignFirstResponder];.
A storyboard is a container which contains your various UI elements, including your text field.
What you really want to do is set a delegate for your text field, which you can do with your view controller.
Then, when you click away from the text field, you can catch that happening via the delegate method "textFieldDidEndEditing:". You implement that function in your view controller, make certain your text field has your view controller set as the delegate, and you should be able to do whatever you want within your view controller's implementation of the "textFieldDidEndEditing:" function.
With a UIControl such as a UIButton you can use something like
myControl.state
to figure out whether the control is currently being pressed down.
However, I need to do the same with some UIBarButtonItems (which are not derived from UIControl), so that I can stop my table from editing while one of them is pressed down.
Here's my code:
- (BOOL)tableView:(UITableView *)tableView canEditRowAtIndexPath:(NSIndexPath *)indexPath {
//other checks
for(int b=0; b<self.toolbar.items.count; b++)
{
UIControl *currentControl= [self.toolbar.items objectAtIndex:b];
if(currentControl.state==UIControlStateHighlighted)
{
return NO;
}
}
return YES;
}
Obviously, it doesn't work, since it assumes that UIBarButtonItems can be treated as UIControls, but how would I do what I'm trying to do here?
If you want more control over your UIBarButtonItems the best thing to do is to recreate them as UIButtons (using custom art, etc), and then use the -initWithCustomView of UIBarButtonItem to create button items from actual UIViews.
This will give you full access to the usual button interactions methods: the only downside is you won't get the nice bar button style by default, and you'll have to provide the art for this yourself.
I had a similar problem before. I couldn't fix it, so I moved on. Here is what I did:
Use ToolBar instead of navigation bar, then use UIButton instead of UIBarButtonItem inside the toolbar.
