如何在iphone的UIPinchGesture中放大后设置uiscrollview的内容大小

为此，我必须在iphone中实现

UIPinchGesture

，我的代码如下：

    - (void)handlePinch:(UIPinchGestureRecognizer*)recognizer
    {
      if ( [recognizer state] == UIGestureRecognizerStateBegan || 
            [recognizer state] == UIGestureRecognizerStateChanged ) 
     {
     NSLog(@"=======Scale Applied===========");
     if ( [recognizer scale]<1.0f ) 
     {
         [recognizer setScale:1.0f];
     }
    CGAffineTransform transform = CGAffineTransformMakeScale([recognizer scale],     [recognizer scale]);
    self.view.transform = transform;

-（void）handlePinch:（UIPinchGestureRecognitor*）识别器
{
如果（[Recognitor state]==UIgestureRecognitzerState开始||
[识别器状态]==UIgestureRecognitzerStateChanged）
{
NSLog（@“=============应用的比例===========”）；
如果（[Recognitor scale]您必须使用
UIScrollView
而不是
UIView
。完成此操作后，您必须调整滚动视图的内容大小

[myScrollView setContentSize:CGSizeMake(width, height)]

如果内容大于屏幕，则scrollview可自动滚动

希望能有帮助
