uislider

I have a custom UISlider that is relatively tough for big fingered people to grab hold of and slide due to the size of the "thumb image". Is there any way to increase the size of clickable / draggable area without altering the size of the image? Here's the code I have for creating the custom slider if that helps: [slider setMaximumTrackImage:[[UIImage imageNamed:@"max.png"] resizableImageWithCapInsets:UIEdgeInsetsMake(0, 20, 0, 20)] forState:UIControlStateNormal]; [slider setMinimumTrackImage:[[UIImage imageNamed:@"min.png"] resizableImageWithCapInsets:UIEdgeInsetsMake(0, 20, 0, 20)] forState

How to detect the event when the user has ended the drag of a slider pointer? If you don't need any data inbetween drag, than you should simply set: [mySlider setContinuous: NO]; This way you will receive valueChanged event only when the user stops moving the slider. You can add an action that takes two parameters, sender and an event, for UIControlEventValueChanged: [slider addTarget:self action:@selector(onSliderValChanged:forEvent:) forControlEvents:UIControlEventValueChanged] Then check the phase of the touch object in your handler: - (void)onSliderValChanged:(UISlider*)slider forEvent:

What I want to get is a UISlider which lets the user not only slide when he starts on its thumbRect , but also when he taps elsewhere. When the user taps on the slider but outside of the thumbRect , the slider should jump to that value and then still keeping up to the user's sliding gesture . What I have tried so far was implementing a subclass of UIGestureRecognizer like in this suggestion . It starts right then when a touch down somewhere outside the thumbRect occurs. The problem is that the slider sets its value but then further sliding gestures are ignored because the touch down recognizer

I am new to iPhone, How do I have my UISlider go from 1 to 100 in increments of 1 ? slider = [[UISlider alloc] init]; [slider addTarget:self action:@selector(sliderChange:) forControlEvents:UIControlEventValueChanged]; [slider setBackgroundColor:[UIColor clearColor]]; slider.minimumValue = 1; slider.maximumValue = 100; slider.continuous = YES; slider.value = 0.0; - (IBAction)sliderChange:(id)sender{ NSLog(@"slider.value=%f",slider.value); } When i slide my log shows... slider.value = 1.000000 slider.value = 1.123440 slider.value = 1.234550 slider.value = 1.345670 slider.value = 1.567890 . . .

Got a gesture related problem. I implemented UISwipeGestureRecognizer to get swipe left and right events and that is working fine. However the problem I'm facing is that the UISlider's I have in the same view are not playing nice. The sliding motion of the sliders is being mistaken as a swipe left/right. Any one experienced this problem before, got any ideas how to correct it? Many thanks. Here is the code contained within the view controller: - (void)viewDidLoad { [super viewDidLoad]; //Setup handling of LEFT and RIGHT swipes UISwipeGestureRecognizer *recognizer; recognizer = [
