在iOS中使用Phonegap防止Webview被上下拖动

在使用PhoneGap制作App的时候，iOS作为承载App页面的容器的Webview，在手指向下或者向上滑动屏幕时，除了页面本身的滚动外，还经常会看到整体页面底部和屏幕底部被拖动出黑屏

为了防止这一滑动，可以通过修改修改项目中的MainViewController.m，重新设置WebView来实现

1	- (void)webViewDidFinishLoad:(UIWebView*)theWebView

2

{

3	// Black base color for background matches the native apps

4	theWebView.backgroundColor = [UIColorblackColor];

5

6	[(UIScrollView *)[[theWebView subviews] objectAtIndex:0] setBounces:NO];

7

8	return [superwebViewDidFinishLoad:theWebView];

9

}

 

在驿驴项目修改的地方是

p.p1 { margin: 0.0px 0.0px 0.0px 0.0px; font: 11.0px Menlo; color: #000000 }
p.p2 { margin: 0.0px 0.0px 0.0px 0.0px; font: 11.0px Menlo; color: #d12f1b }

span.s1 { }

span.s3 { color: #703daa }
span.s4 { color: #000000 }
span.s5 { color: #78492a }
span.s6 { font: 11.0px Menlo; color: #000000 }
span.s7 { font: 11.0px Menlo }
span.s8 { color: #272ad8 }
span.s9 { color: #4f8187 }
span.s10 { color: #31595d }
span.s11 { color: #3e1e81 }

- (void)webViewDidFinishLoad:(UIWebView*)webView

{

VerboseLog(@"webView didFinishLoad (before). state=%d loadCount=%d", _state, _loadCount);

BOOL fireCallback = NO;

// 禁止滚动上下滚动

[(UIScrollView *)[[webView subviews] objectAtIndex:0] setBounces:NO];

switch (_state) {

case STATE_IDLE:

break;

case STATE_WAITING_FOR_LOAD_START:

NSLog(@"CDVWebViewDelegate: Unexpected didFinish while waiting for load start.");

break;

case STATE_WAITING_FOR_LOAD_FINISH:

if (_loadCount == 1) {

fireCallback = YES;

_state = STATE_IDLE;

}

_loadCount -= 1;

break;

case STATE_IOS5_POLLING_FOR_LOAD_START:

[self pollForPageLoadStart:webView];

break;

case STATE_IOS5_POLLING_FOR_LOAD_FINISH:

[self pollForPageLoadFinish:webView];

break;

}

VerboseLog(@"webView didFinishLoad (after). state=%d loadCount=%d fireCallback=%d", _state, _loadCount, fireCallback);

if (fireCallback && [_delegate respondsToSelector:@selector(webViewDidFinishLoad:)]) {

[_delegate webViewDidFinishLoad:webView];

}

}

其实还可以这样

修改config.xml

<preference name="WebViewBounce" value="false" />

<preference name="DisallowOverscroll" value="true" />
