我正在尝试使用
swift制作活动指示器,但有一些我缺少的东西
以下是启动活动按钮按钮的代码：
Indicator = ActivityIndicator().StartActivityIndicator(ViewController());
这是停止活动按钮的代码
ActivityIndicator().StopActivityIndicator(ViewController(),indicator: Indicator);
和ACtivity指标类的代码是
class ActivityIndicator: NSObject {
var myActivityIndicator:UIActivityIndicatorView!
func StartActivityIndicator(obj:UIViewController) -> UIActivityIndicatorView
{
self.myActivityIndicator = UIActivityIndicatorView(frame:CGRectMake(100,100,100)) as UIActivityIndicatorView;
self.myActivityIndicator.activityIndicatorViewStyle = UIActivityIndicatorViewStyle.Gray
self.myActivityIndicator.center = obj.view.center;
obj.view.addSubview(myActivityIndicator);
self.myActivityIndicator.startAnimating();
return self.myActivityIndicator;
}
func StopActivityIndicator(obj:UIViewController,indicator:UIActivityIndicatorView)-> Void
{
indicator.removeFromSuperview();
}
}
Thanks Problem Solved
while am writing code I kNow that time that I have to pass self in the
function but at that time I didn’t kNow What type is self referencing
so I I can’t receive until I kNow the type then I decide to try to
receive different type (UIView,
UIActivityIndicatorView,UIViewController) then I found That it should
be UIViewController but I forgot that it should be pass with self and
I looking for what to pass in function calling and I thought let’s try
UIViewController and it didn’t give me error so I thought it’s right
but when it’s not working I thought I am close enough so it’s better
to ask expert about the problem. And as I expected problem is solved
within few minutes
Swift 3版
class ActivityIndicator: NSObject {
var myActivityIndicator:UIActivityIndicatorView!
func StartActivityIndicator(obj:UIViewController) -> UIActivityIndicatorView
{
self.myActivityIndicator = UIActivityIndicatorView(frame:CGRect(x: 100,y: 100,width: 100,height: 100)) as UIActivityIndicatorView
self.myActivityIndicator.activityIndicatorViewStyle = UIActivityIndicatorViewStyle.gray
self.myActivityIndicator.center = obj.view.center;
obj.view.addSubview(myActivityIndicator);
self.myActivityIndicator.startAnimating();
return self.myActivityIndicator;
}
func StopActivityIndicator(obj:UIViewController,indicator:UIActivityIndicatorView)-> Void
{
indicator.removeFromSuperview();
}
}
