视图在 iOS 中自动取消隐藏

Question

I have created a view on interface & reducing its height on click of a button with uianimation.Below is the code for the animation

@IBAction func filterClick(sender: AnyObject) {

    STF_Search.resignFirstResponder()
    UIView.animateWithDuration(0.3, animations:{

        if(self.isFilter==false){

            self.filterView.frame=CGRectMake(0,117,self.view.frame.size.width,50)
            self.STVRA.frame=CGRectMake(0, 168,self.STVRA.frame.size.width,self.STVRA.frame.size.height)
            self.isFilter=true
        }
        else{

            self.filterView.frame=CGRectMake(0,117,self.view.frame.size.width,0)
            self.tableView.frame=CGRectMake(0, 117,self.STVRA.frame.size.width,self.STVRA.frame.size.height)
            self.dateTo="nil"
            self.dateFrom="nil"
            self.isControlls(true)
            self.isFilter=false
        }
    }
        ,completion: {(_) -> Void in

            if(self.isFilter==true){

                self.isControlls(false)
            }
            else{

             self.callRAListWebApi()

            }
    })
}

Code working perfectly if I don't call the method "self.callRAListWebApi()" on the other hand in above scenario when execution of this methods complete the "filterView" gets into its default height-> 50 which is not supposed as per the logic it should be "0" ("callRAListWebApi" is a method where I am hitting a web api & getting some json response) I cant understand this unusual behaviour of "filter view" of coming in its original height.I have checked everything there is no clue.

创建视图的autolayout ，因为问题是因为您正在直接更改框架。
