2015-02-03 22:44:17.472 descuentos[1430:55158] *** Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '-[UIButton value]: unrecognized selector sent to instance 0x7fde78d95440'
*** First throw call stack:
How can I fix this error? I think this is a thread error.
Here is my code:
- (IBAction)TipsSlider:(id)sender {
UISlider *slider = sender;
float valorFloat = slider.value;
int valInt = (int)valorFloat;
_dataSlider.text = [[NSString alloc]initWithFormat:#"%d", valInt];
}
- (IBAction)calcular:(id)sender {
UISlider *slider = sender;
float valorFloat = slider.value;
int valInt = (int)valorFloat;
_dataSlider.text = [[NSString alloc]initWithFormat:#"%d", valInt];
float valorIn= [[entrada text] floatValue];
float resultado = (valorFloat / 100) * valorIn;
NSString *resultadoFinal = [[NSString alloc]initWithFormat:#"%4.2f",resultado];
_salidaResultado.text = resultadoFinal;
}
It looks like you have connected an IBAction from a UIButton when you intended to use a UISlider.
You then assign the sender of the action (which is a button) to a slider and try to access its "value", only that UIButton instances do not respond to a "value" message and that's why you get the crash.
So, make sure you are "ctrl+dragging" from a slider in IB.

i have created one custom cell and put button on it
and button event is like this
[cell.BtnRequest addTarget:self action:#selector(didTapButton:) forControlEvents:UIControlEventTouchUpInside];
and didtapbutton code is this
- (void)didTapButton:(id)sender {
WorkerDetailsVC *wvc=[self.storyboard instantiateViewControllerWithIdentifier:#"workerdetailsvc"];
NSIndexPath *indepath = [self.tblorderdata indexPathForCell:sender];
wvc.arrworkarrequest=[arrData objectAtIndex:indepath.row];
NSLog(#" arr send :%#", wvc.arrworkarrequest);
wvc.struserid = struserid;
[self.navigationController pushViewController:wvc animated:YES];
}
and on the next page i got the array arrworkarrequest and after the load all next page it will show error like this

Your problem is that sender is of type UIButton not UITableViewCell so it's getting stuck in the [self.tblorderdata indexPathForCell:sender] because that method call expects a type of UITableViewCell.
You need to find the Cell that the button is in. You may be able to do this using a while loop (although it's a bit horrible). Something like:
id obj = sender;
while (![obj isKindOfClass:[UITableViewCell class]]) {
obj = [sender superview];
}
[self.tblorderdata indexPathForCell:obj];
This feels like it's abusing the view hierarchy though.
This happens if you compare the length of a string directly
for example
NSString *myString = #"2";
using this statement will generate the error
if(myString.length==2)
I want to design a level select scene in my game. What I want is a very abstract design which consists of a single UIPickerView that has the width of the screen and about 200 px in height.
The following is from LevelSelect.m , which is a subclass of SKScene
-(id)initWithSize:(CGSize)size{
if (self = [super initWithSize:size]) {
/* Setup your scene here */
self.backgroundColor = [SKColor whiteColor];
for (int i = 0; i < 10; i++) {
NSString* levelString = [NSString stringWithFormat:#"Level %i",i];
[levelData setObject:levelString atIndexedSubscript:i];
}
UIPickerView *levelPickerView = [[UIPickerView alloc] initWithFrame:CGRectMake(self.scene.size.width/2, self.scene.size.height/2, self.scene.size.width, 200)];
levelPickerView.dataSource = self;
levelPickerView.delegate = self;
levelPickerView.showsSelectionIndicator = YES;
[self addChild:levelPickerView];
}
return self;
}
I implemented the UIPickerView data source and delegate methods. But when i load the scene i get the following error .

thanks in advance.
Im attempting to make the title of a UIButton the favorites count of the particular tweet from twitter. I can functionally attain the number and I am successfully authorized with Twitter. Here is how I am attempting to set the Title:
//Set number of Favorites for Tweet
NSObject *favoritesCount = [[tweet objectForKey:#"user"]objectForKey:#"favourites_count"];
UIButton *favoritesButton = (UIButton *)[cell viewWithTag:204];
favoritesButton.titleLabel.text = favoritesCount;
When I run this I get the error at favoritesButton.titleLabel.text = favoritesCount;
Here is the error I am getting:
*** Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '-[__NSCFNumber length]: unrecognized selector sent to instance 0x8d3a3a0'
Title should be NSString value. You need to set title as NSString not NSObject.
NSInteger favoritesCount = [[tweet objectForKey:#"user"]objectForKey:#"favourites_count"];
UIButton *favoritesButton = (UIButton *)[cell viewWithTag:204];
favoritesButton.titleLabel.text = [NSString stringWithFormat:#"%d",favoritesCount];
In my game, when I load a new level, the previous level seems to be still remaining in the view.. Each level has its own class and they all draw something on the screen. So if I have 2 or more levels of images loaded, that makes my game too slow. What can I do to unload the previous level? Thanks in advance..
- (void) finishedLevel: (Level *) level
{
levelNumber++;
levelClass = NSClassFromString([NSString stringWithFormat:
#"Level_%d", levelNumber]);
if (!levelClass) levelClass = [Level class];
currentLevel = [[levelClass alloc] initWithView: self.mainView];
self.mainView.levelLabel.text = [NSString stringWithFormat:#"Level %d", levelNumber];
gameRunning = NO;
}
I tried using the following but didn't really work
levelClass = NSClassFromString([NSString stringWithFormat:#"Level_%d", levelNumber-1]);
[levelClass removeFromSuperview];
Error message
