将标签转换为全局变量

i need to get a value from a stepper into a global variable. i first tried to do this,

我需要从步进器获取一个值到全局变量。我第一次尝试这样做，

NSInteger MYGlobalVariable =0;


-(IBAction)time:(UIStepper *)sender {
int value = [sender value];
MYGlobalVariable = (int)value;}


reloadtimer=[NSTimer scheduledTimerWithTimeInterval:MYGlobalVariable target:self selector:@selector(WebViewLoad:) userInfo:nil repeats:YES];}

the last part of that code was a timer from my webview, but the gvariable wont change with the stepper, so is there a way this works or ..

该代码的最后一部分是来自我的webview的计时器，但是gvariable不会随着步进器而改变，所以有一种方法可行或者......

i could do the stepper with a label and then convert that into the global variable? but i dont know how to do that either

我可以用标签做步进器然后将其转换为全局变量？但我也不知道该怎么做
