iOS controlling a slider value and text label value with a stepper

谁说我不能喝 提交于 2020-01-16 18:10:09
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 Figuring out whether the plus or minus button was pressed in UIStepper I use this method: - (void)stepperOneChanged:(UIStepper*)stepperOne And I compare stepperOne.value with a global value saved in my TableView Class.

So to clarify i will show the "bad" code i am using: - (void)stepperOneChanged:(UIStepper*)stepperOne { BOOL PlusButtonPressed=NO; if(stepperOne.value>globalValue) { PlusButtonPressed =YES; } globalValue=stepperOne.value; ////do what you need

时间秒杀一切 提交于 2019-12-13 06:03:53
问题 I have the following code. However, the line stepper.value = [NSNumber numberWithDouble:loadNumber]; errors with the error 'Sending NSNumber *__strong to a parameter of incompatible type 'double''. I think the stepper will only accept a double, but am unsure what I am doing wrong to set it.

How to get stepper and longpress to coexist?

Just to be clear, here is the way the screen was set up when I tried this. App was set up with a simple view controller. A subview was added to this view (could have been a controller, but I just

Stepper value reset after loaded from coredate

吃可爱长大的小学妹 提交于 2019-12-12 02:57:57
问题 I am building a UITabledetail view, which contains a stepper and a UILabel. The uilabel will show the number of stepper pressed. My problem comes when i used core data to save the value of the uilabel. e.g. the final value of the uilabel is 30.

Below is my code. - (IBAction)stepperValueChanged:(id
