I have this code:
UIButton *btn1 = [UIButton buttonWithType:UIButtonTypeCustom];
UIImage *imgIcon = imageNamed(#"icon_1.png");
[btn1 setImage:imgIcon forState:UIControlStateNormal];
CGPointMake(textField.frame.size.width+textField.frame.origin.x+btnTalk.frame.size.width/2, textField.frame.origin.y+textField.frame.size.height/2);
[btnTalk addTarget:textField action:#selector(Hello:) forControlEvents:UIControlEventTouchUpInside];
[self.view addSubview:btnTalk];
i can tap in UIbutton and it works
but i want to call with other button
i want create one IBAction for call this UIButton
i writes this code but doesn't work & textfield is (objectOfAnotherClass)
-(IBAction)call1
{
[textField Hello];
}
I think you should do like this:
[btnTalk addTarget:self action:#selector(Hello:) forControlEvents:UIControlEventTouchUpInside];
-(IBAction)call1
{
[self Hello:nil];
}
I think that you are looking for sendActionsForControlEvents that helps you to 'simulate' the action of touching the button... Here the method description.

We are trying to trigger display button from static library project using webview. while integrating static library with single view application we have got the output design. but when we tried to attempt action by clicking on Button its not working.
Below is the code,which we have used inside cocoa touch static library
UIButton *imageButton = [UIButton buttonWithType:UIButtonTypeCustom];
imageButton.frame = CGRectMake(self.view.frame.size.width-50, 10, 50, 50);
[imageButton setImage:[UIImage imageNamed:#"close.png"] forState:UIControlStateNormal];
imageButton.adjustsImageWhenHighlighted = NO;
// [imageButton addTarget:self action:#selector(close:) forControlEvents:UIControlEventTouchUpInside];
[imageButton addTarget:self action:#selector(hideWebViewBtn:) forControlEvents:UIControlEventTouchUpInside];
-(IBAction)hideWebViewBtn:(id)sender {
NSLog(#"Hide Button clicked");
[self.adView removeFromSuperview];
self.adView = nil;
return;
}
Below is the screenshot which displayed in single view application after integration and running.
Once i click on the button its not getting clicked.
try this,whether self button is triggering or not..
[self.myButton sendActionsForControlEvents:UIControlEventTouchUpInside];
It worked for me
You should add your button to a super view.And also,the super view should enable user interfaces.
[yourSuperView addSubView:button];yourSuperView.userInteractionEnabled=YES;
How about you change your return type of your 'hideWebViewBtn' method from 'IBAction' to 'void'?
"Once i click on the button its not getting clicked." You mean that u click the close button,but it doesn't call the function hideWebViewBtn:() ?
You can try this.
UIButton *imageButton = [[UIButton alloc] initWithFrame:CGRectMake(self.view.frame.size.width-100, 10, 50, 50)];
[imageButton setImage:[UIImage imageNamed:#"close.png"] forState:UIControlStateNormal];
[self.view addSubview:imageButton];
[self.view bringSubviewToFront:imageButton];
[imageButton removeTarget:self action:NULL forControlEvents:UIControlEventAllEvents];
[imageButton addTarget:self action:#selector(hideWebViewBtn:) forControlEvents:UIControlEventTouchUpInside];
Hope it works for you. Thanks!
I want to create and remove uibutton. (iOS7)
My viewDidLoad function creates uibutton in the following way:
for (char a = 'A'; a <= 'Z'; a++)
{
position = position+10;
UIButton *button = [UIButton buttonWithType:UIButtonTypeRoundedRect];
[button addTarget:self
action:#selector(getByCharacter:)
forControlEvents:UIControlEventTouchUpInside];
[button setTitle:[NSString stringWithFormat:#"%c", a] forState:UIControlStateNormal];
button.frame = CGRectMake(position, self.view.frame.size.height-40, 10.0, 10.0);
button.tintColor = [UIColor whiteColor];
[self.view addSubview:button];
}
Now I want to remove specific uibutton based on button text.
- (IBAction)getByCharacter:(id)sender{
}
I don't know how to do this. Can anyone provide some sample code?
You can remove the button by calling
[sender removeFromSuperview];
in your callback (getByCharacter:). When you attach the selector to the button, the sender parameter will be the button which triggered the event. That means that you have an instance of it. With this instance you can now calll the removeFromSuperview method.
First you need to get the button's title text and then remove it from superView if it matches to the specific character,
- (IBAction)getByCharacter:(id)sender{
UIButton *myButton = (UIButton *) sender;
if([myButton.titleLabel.text isEqualToString:#"C"]{
[myButton removeFromSuperView];
}
}
I have set a UIButton like this :
UIButton *learnmorebutton = [UIButton buttonWithType:UIButtonTypeRoundedRect];
and I have
[learnmorebutton addTarget:self action:#selector(myAction) forControlEvents:UIControlEventTouchUpInside];
and i have a void
- (void)myAction
{
}
but i cannot see learnmorebutton in the void, and thats because #property.
is this correct ?
All UIControls pass themselves as a "sender" to their target action methods IF the selector you give them takes 1 parameter.
Make these changes:(note the colon after the myAction selector on the first line)
[learnmorebutton addTarget:self action:#selector(myAction:) forControlEvents:UIControlEventTouchUpInside];
- (void)myAction:(UIButton *)sender
{
//sender is the button that was tapped
sender.backgroundColor = [UIColor redColor]; //or whatever color you wanted here.
}
Introduction:
I'm creating my UIBUTTON at runtime. And my UIButton is in a TableView. The whole function of this UIButton is: If I click on "delete OFF" or "delete ON" (normal void Method) I can delete each cell in my TableView. I took the position of my UIButton on the right side like the real delete-method.
First of all, I know that Objective-C has got a delete-method! But I cant use this method, because I have Sliders in my TableView and sliders with Objective-C delete method doesn't work together.
Because of this, I have written this Code:
- (UITableViewCell *) getCellContentView:(NSString *)cellIdentifier {
if (allowchange==YES) //<- Button to activate the delete mode
{
UIButton *playButton = [[UIButton buttonWithType:UIButtonTypeRoundedRect] retain];
playButton.frame = CGRectMake(700, 23, 45, 25);
[playButton setBackgroundImage:[UIImage imageNamed:#"button_delete.png"]
forState:UIControlStateNormal];
[self.view addSubview:playButton];
[playButton addTarget:self action:#selector(deleteRow:) forControlEvents:UIControlEventTouchDown];
playButton.tag=count;
[cell.contentView addSubview:playButton];
[playButton release];}}
When I touch the button at that time I want to change image & when i release the touch button image is as it is.
I want to apply below code but it's not with my expectation.
please give me any suggestion.....
-(IBAction)actionEnter:(id)sender{
if ([sender isSelected]) {
[sender setImage:[UIImage imageNamed:#"enter-hover.png"]
forState:UIControlStateNormal];
[sender setSelected:NO];
} else {
[sender setImage:[UIImage imageNamed:#"enter.png"]
forState:UIControlStateSelected];
[sender setSelected:YES];
}
You can use UIControlStateHighlighted for this.
[myButton setImage:[UIImage imageNamed:#"enter-hover.png"]
forState:UIControlStateHighlighted];
You can also set this from interface builder by setting the image for highlighted state.
I think this should do it. Set the images after creating the button
[yourButton setImage:[UIImage imageNamed:#"enter-hover.png"]
forState:UIControlStateSelected];
[yourButton setImage:[UIImage imageNamed:#"enter.png"]
forState:UIControlStateNormal];
and do this
- (IBAction)actionEnter:(id)sender{
UIButton *button = (UIButton *)sender;
button.selected = !button.selected;
}
In Swift:
button.setImage(UIImage(named: "enter.png"), forState: [.Selected, .Highlighted])
I think, you could set the image in the beginning for normal and selected state ..
Try with below when you create the UIButton object. [Use the images as per your requirement]
[myButton setImage:[UIImage imageNamed:#"enter.png"]
forState:UIControlStateNormal];
[myButton setImage:[UIImage imageNamed:#"enter-hover.png"]
forState:UIControlStateSelected];
#7KV7 got me thinking. I have favorite and ignore buttons that I want to use to mark favorite pictures and pictures that I never want to see again. I used his method to initialize the buttons and then slightly modified his method to toggle the buttons on and off.
In this example, if you mark a picture as a favorite, you want to turn off the ignore button and vice versa. The delegate handles the database stuff.
self.favoriteButton = [UIButton buttonWithType:UIButtonTypeCustom];
self.ignoreButton = [UIButton buttonWithType:UIButtonTypeCustom];
[self.favoriteButton setImage:[UIImage imageNamed:#"Favorite-Selected"]
forState:UIControlStateSelected];
[self.favoriteButton setImage:[UIImage imageNamed:#"Favorite"]
forState:UIControlStateNormal];
[self.ignoreButton setImage:[UIImage imageNamed:#"Ignore-Selected"]
forState:UIControlStateSelected];
[self.ignoreButton setImage:[UIImage imageNamed:#"Ignore"]
forState:UIControlStateNormal];
If you are just toggling a button on or off, you won’t need to make it a property, since the buttonPressed sender knows which button has been pressed. I need to have them be property since I need to tell the opposite button to turn its highlight off.
- (void)favoriteIgnore:(UIButton *)buttonPressed {
// Toggle the tapped button
buttonPressed.selected = ( buttonPressed.selected) ? NO : YES;
id <ScoringToolbarDelegate> TB_delegate = _delegate;
// Turn off the other button and call the delegate
if ([buttonPressed.currentTitle isEqualToString:#"favorite"]) {
self.ignoreButton.selected = NO;
[TB_delegate favoriteButtonPressed];
} else {
self.favoriteButton.selected = NO;
[TB_delegate ignoreButtonPressed];
}
}
to change the image immediately use the backgroundImage property.
