uislider

问题 I've been searching for a way to make the UISlider progress bar taller, that is, increase the height. However, I haven't had any success. I don't want to use a custom image or anything, just make it taller, so the UISlider doesn't look so thin. Am I missing something super obvious? 回答1: The accepted answer will undesirably change the slider's width in some cases, like if you're using a minimumValueImage and maximumValueImage . If you only want to change the height and leave everything else

问题 I'm having trouble with UISlider and AVPlayer scrubbing method. Every time the method is invoked the player restarts from 0. I tried debugging and seems that the slider value is right but when I Step Over, it's set 0, thus the player restarts. This is what I've tried: var desiredTime = CMTimeMake(Int64(self.progressSlider.value), 1) AudioManager.sharedInstance.audioPlayer.seekToTime(desiredTime) I've also tried looking at similar questions and found that it was the same when I tried their

问题 My code needs some help from professional xcoders :-) I have a draggable uitextview called "headline" that is a subview in "mainstage". I also added a pinch gesture to change the fontsize inside the uitextview. Everything works fine but the last essential feature that I really need is the rotation of the uitextview. So I added a uislider for rotation and volia! it also works. But after this transformation the uitextview goes crazy* when it becomes a new size via the pinch gesture. (*The

问题 I can detect single/double-taps in specific views with: NSSet *myTouches = [event touchesForView:mySpecificView.view]; but I want to detect a double-tap on the button of a slider and can't find any reference to it. Is there a replacement for "touchesForView:" where I can enter the name of my slider? usage: I have three sliders with their default value being directly in the center of the slider. Once the position of the slider has changed, I want a quick way to individually reset each slider

问题 I already have a slider that controls the output of a text label. -(IBAction)mySlider:(UISlider *)sender { _myTextLabel.text = [NSString stringWithFormat:@"%i", (int) sender.value]; } However, I also want a stepper to be able to changer the slider's position. So, if the slider has been set to 50, and the text label says 50, I want the stepper to increment to 51, 52, 53, etc. Does anyone know the code to do this? Thanks! 回答1: You will need to keep an reference for the UISlider . Make a handler

问题 I have a UISlider that slides with a range from 0.0 to 1.0. Out of the box, the slider lets users slide with a really high number of fraction digits, but I only want my users to be able to increment/decrement by .001 for each "tick" up or down of the slider. Is this possible to set up? Thank you! 回答1: How big is this slider? Even if you've got it spanning the full width of the screen in landscape mode, a change of 0.001 is only about half a pixel. It sounds like you just need to round the

问题 I'm playing songs in AVPlayer . I have created a separate view controller for my media player and initialization, and all the methods that I'm using for the player (play, pause, repeat, shuffle) are there in the same view controller. I update a slider like this: [NSTimer scheduledTimerWithTimeInterval:1.0 target:self selector:@selector(sliderUpdate:) userInfo:nil repeats:YES];` - (void) sliderUpdate:(id) sender{ int currentTime = (int)((song.player.currentTime.value)/song.player.currentTime

问题 I have a slider that goes from 1 to 10 and I want to store the value that the user chose with the slider every time. I want the value to get updated with the movement of the slider. This is what I have so far def PrintValue(): print value cmds.floatSliderGrp(label='Angle', field=True, minValue=0.0, maxValue=10.0, value=0 ,dc=PrintValue(PASSVALUE) ) I want to pass the value where the PASSVALUE argument is, is there a way to get the value from the slider? 回答1: 'value' is a flag for the

问题 I'm customizing a UISlider . I could set a custom thumb image that is higher than the usual thumb however I could not make the track higher when setting a higher minimum track image but the track height remained the same. It should be possible as in the iPod/Music App on the iPad the volume slider is also higher as the usual slider as you can see here: (source: cocoia.com) 回答1: You need to subclass the slider and override the trackRectForBounds: method, like this: - (CGRect)trackRectForBounds
