縮放uiscrollview也放大一個

我在我的項目中有一個屏幕，其中包含3 UIScrollView。這些滾動視圖包含一個圖像，當我試圖縮放滾動視圖我不知道如何，但他們都放大在一起。縮放uiscrollview也放大一個

這是我的代碼：

if ([FrameString isEqualToString:@"LB"]) { 
    leftButton.hidden = YES; 

    if (imageLeft == nil) { 
     imageLeft = [[UIImageView alloc]initWithImage:pickedImage]; 
    } 

    imageLeft.frame = CGRectMake(0 , 0, imageLeft.frame.size.width/4, imageLeft.frame.size.height/4); 
    self.Scrollview.maximumZoomScale = 0.9; 
    self.Scrollview.minimumZoomScale = 0.6; 
    self.Scrollview.frame = CGRectMake(self.Scrollview.frame.origin.x, self.Scrollview.frame.origin.y, self.Scrollview.frame.size.width, self.Scrollview.frame.size.height); 
    [self.Scrollview setContentSize:CGSizeMake(imageLeft.frame.size.width, imageLeft.frame.size.height)]; 
    self.Scrollview.clipsToBounds = YES; 
    self.Scrollview.delegate = self; 
    [self.Scrollview setScrollEnabled:YES]; 
    [self.Scrollview addSubview:imageLeft]; 
} 

if ([FrameString isEqualToString:@"RDB"]) { 
    RightDownButton.hidden = YES; 
    if (RightDown == nil) { 
     RightDown = [[UIImageView alloc]initWithImage:pickedImage]; 
    } 

    RightDown.frame = CGRectMake(0 , 0, RightDown.frame.size.width/3, RightDown.frame.size.height/3); 
    self.scrollview1.maximumZoomScale = 0.9; 
    self.scrollview1.minimumZoomScale = 0.6; 
    self.scrollview1.frame = CGRectMake(self.scrollview1.frame.origin.x, self.scrollview1.frame.origin.y, self.scrollview1.frame.size.width, self.scrollview1.frame.size.height); 
    [self.scrollview1 setContentSize:CGSizeMake(RightDown.frame.size.width, RightDown.frame.size.height)]; 
    self.scrollview1.clipsToBounds = YES; 
    self.scrollview1.delegate = self; 
    [self.scrollview1 setScrollEnabled:YES]; 
    [self.scrollview1 addSubview:RightDown]; 

} 
if ([FrameString isEqualToString:@"RUB"]) { 
    rightUpButton.hidden = YES; 
    if (RightUp == nil) { 
     RightUp = [[UIImageView alloc]initWithImage:pickedImage]; 
    } 

    RightUp.frame = CGRectMake(0 , 0, RightUp.frame.size.width/3, RightUp.frame.size.height/3); 
    self.scrollview2.maximumZoomScale = 0.9; 
    self.scrollview2.minimumZoomScale = 0.6; 
    self.scrollview2.frame = CGRectMake(self.scrollview2.frame.origin.x, self.scrollview2.frame.origin.y, self.scrollview2.frame.size.width, self.scrollview2.frame.size.height); 
    [self.scrollview2 setContentSize:CGSizeMake(RightUp.frame.size.width, RightUp.frame.size.height)]; 
    self.scrollview2.clipsToBounds = YES; 
    self.scrollview2.delegate = self; 
    [self.scrollview2 setScrollEnabled:YES]; 
    [self.scrollview2 addSubview:RightUp]; 
}

在縮小，其呼籲雙方scrollViews相同的委託。因此，無論哪個scrollView正在縮放，委託方法中的所有內容都得到了實現。

一個簡單的方法來解決這個問題是設置一個標籤爲兩個scrollviews

像self.Scrollview.tag = 1 ADN self.scrollview1.tag = 2

檢查在滾動視圖的委託方法

標籤且僅當運行標籤匹配您感興趣的標籤。

例如： -

- (UIView *)viewForZoomingInScrollView:(UIScrollView *)scrollView{ 

if (scrollView.tag == TagYouAreInterestedIn){ 
    //do stuff 

    } 
    return view; 
}

希望這會有所幫助。
