来自 XIB 添加 UISwitch

解决方案

我有很多用户面临同样的问题，所以这可能是 UISwitch 的错误，所以我现在才找到临时解决方案.我发现了一个 gitHub 自定义 KLSwitch 现在使用它希望苹果会在 xCode 的下一次更新中解决这个问题:-

Hi Today i seen in UISwitch's Event ValueChanged: Calling continuously while i am change to On to Off or Off to On and my finger moved still on right side as well as left side. I atteched GIF image for more clear with NSLog.

My Value Changed Method is:

- (IBAction)changeSwitch:(id)sender{

    if([sender isOn]){
        NSLog(@"Switch is ON");
    } else{
        NSLog(@"Switch is OFF");
    }
    
}

iOS6 the same code of Switch working Fine as we expectation:

so can anyone suggest me that call only one time its state On or off. or is this is a bug or what..?

UPDATE

Here it is my Demo of it:
