Terminating app due to uncaught exception
'NSInvalidArgumentException', reason: '-[UISlider
setPopUpViewCornerRadius:]: unrecognized selector sent to instance
0xa44bef0'
Code:
self.slider1.maximumValue = 255.0;
self.slider1.popUpViewCornerRadius = 25.0;
[self.slider1 setMaxFractionDigitsDisplayed:0];
self.slider1.popUpViewColor = [UIColor colorWithHue:0.55 saturation:0.8 brightness:0.9 alpha:0.7];
self.slider1.font = [UIFont fontWithName:#"GillSans-Bold" size:22];
self.slider1.textColor = [UIColor colorWithHue:0.55 saturation:1.0 brightness:0.5 alpha:1];
Please guide me, Thanks in Advance
UISlider doesn't have this property popUpViewCornerRadius, because of that this error is occurring. You will need to remove this below line.
self.slider1.popUpViewCornerRadius = 25.0;
When you are allocating self.slider you need to use ASValueTrackingSlider instead of UISlider.
if you are using story board or xib you need to give ASValueTrackingSlider in identity inspector. like
http://cocoadocs.org/docsets/ASValueTrackingSlider/0.9.2/Classes/ASValueTrackingSlider.html refer the link.
UiSlider does not have this property of
popUpViewCornerRadius
Either remove this line else this property would be included in the Custom class.
So change the UISlider *slider1 to ASValueTrackingSlider *slider1

I have an Application, that takes Restaurants from shared Google Api and displays it in a table view.Then i use
Carbon-kit
for pull to refresh content of tableview
refresh = [[CarbonSwipeRefresh alloc] initWithScrollView:self.tblRest];
//[refresh setMarginTop:120];
[refresh setColors:#[[UIColor blueColor], [UIColor redColor], [UIColor orangeColor], [UIColor greenColor]]];
[self.view addSubview:refresh];
[refresh addTarget:self action:#selector(pullToRefresh:) forControlEvents:UIControlEventValueChanged];
When i scroll my table and try to refresh it, It gives me below error:-
Terminating app due to uncaught exception 'NSRangeException', reason: '*** -[__NSArrayM objectAtIndex:]: index 2 beyond bounds for empty array'
please help me for this error.
Thanking you in advance.
This is happening because you must be initializing your array again while refreshing.
I am using this link here to change the font and color of title in navigation bar. I also tried this. Both of them run fine in ios8 but when i test in ios7 each time it crashes at "NSFontAttributeName". If i remove the code to set the font and only set the color , it works.
The crash message that I get is * Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '*** -[__NSPlaceholderDictionary initWithObjects:forKeys:count:]: attempt to insert nil object from objects[1]
Any help would be appreciated. Hope my problem is clear.
Use this code:
UINavigationBar *navBar = [UINavigationBar appearance];
[navBar setTitleTextAttributes:#{NSFontAttributeName: [UIFont fontWithName:#"yourFont" size:15]];
Try this, it works fine for me in both IOS8 as well as IOS7
`
NSShadow * shadow = [[NSShadow alloc] init];
shadow.shadowColor = [UIColor clearColor];
shadow.shadowOffset = CGSizeMake(0, 0);
[self.navigationBar setTitleTextAttributes:#{NSForegroundColorAttributeName:#"custom-color",
NSShadowAttributeName: shadow,
NSFontAttributeName: #"font-name",
}];`
I have this code:
UIGraphicsBeginImageContextWithOptions(CGSizeMake(100, 100), NO, 0);
UIFont* font = [UIFont systemFontOfSize:12.0f];
NSDictionary* attributes = #{ NSFontAttributeName: font };
[#"hello" drawInRect:CGRectMake(0, 0, 100, 100) withAttributes:attributes];
UIGraphicsEndImageContext();
It crashes in drawInRect with
-[__NSDictionaryI font]: unrecognized selector sent to instance 0xcb77be0
* Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '-[__NSDictionaryI font]:
unrecognized selector sent to instance 0xcb77be0'
It works fine if I use deprecated
[#"hello" drawInRect:CGRectMake(0, 0, 100, 100) withFont:font];
What am I doing wrong?
The reason is you deployed your app on old iOS versio (<7.0) which didn't support method drawInRect:withAttributes:. Also, that's why you could run the deprecated one without problem.
I wand to disable userinteraction for a UIButton of type RoundedRect. I tried
[previousAudio userInteractionEnabled:NO];
But got the exception
Terminating app due to uncaught exception NSInvalidArgumentException, reason: -[UIRoundedRectButton userInteractionEnabled:]: unrecognized selector sent to instance
what can I do instead to disable userinteraction ?
Thanks.
you can use previousAudio.enabled = NO OR YES instad of [previousAudio userInteractionEnabled:NO];
It should be:
[previousAudio setUserInteractionEnabled:NO];
or
previousAudio.userInteractionEnabled = NO;
Because there's no userInteractionEnabled: selector. userInteractionEnabled is getter. In order to set property you should use button.userInteractionEnabled = NO or [button setUserInteractionEnabled:NO]
Use setUserInteractionEnabled:NO instead of userInteractionEnabled:NO
[previousAudio setUserInteractionEnabled:NO];
It doesn't matter that your button is roundedRect or has some other property.
you can set it as desiabled previousAudio.enabled = NO or you can set a condition in the iBAction method
-(IBAction)previousAudioPressed:(id)sender{
if (condition ){
//do something
}
}
I have a UIView in which i have written the following method:
- (void)drawLabels:(NSMutableArray*)labelArray{
for (int i=0; i<[labelArray count]; i++) {
CGRect labelFrame = CGRectMake(0, 0, 50, 50);
labelFrame = CGRectInset(labelFrame, 5, 5);
UILabel *label = (UILabel*)[labelArray objectAtIndex:i];
[self addSubview:label];
}
The code crashes with the following error :
-[UIDeviceRGBColor superview]: unrecognized selector sent to instance 0x6e397c0
2012-11-27 18:37:33.559 QuartzSample[57621:f803] * Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '-[UIDeviceRGBColor superview]: unrecognized selector sent to instance 0x6e397c0'

terminate called throwing an exception(lldb)
I wish to place the labels on the view with all the formatting(color, font,size,etc.).
Also when i put the following code :
NSLog(#"%#",[labelArray objectAtIndex:i]);
i get the following in console:
UIDeviceRGBColorSpace 0 1 0 0.3
Can anybody elaborate ?
It seems you are settings labelFrame but you are not using it.
Before using addSubView, ensure label is not nil
To configure the font and size of a UILabel use setFont: method passing a UIFont as parameter
To configure the color use .textColor property passing a UIColor as parameter
