iPhone开发中如何使UIWebView响应Touch事件是本文要介绍的内容,主要是来介绍如何使UIWebView响应Touch事件,具体内容来看本文详解。UIWebView响应不了Touch事件,很久以前就很难解决。***有一个叫做UICWebView的东西,虽然用了private api,但是可以用。
不过UICWebView或者任何用UIWebDocumentView获得事件的方法在iOS4 100%会出错(因为UIWebDocumentView这个东西没了)。用下面的方法可以让UIWebView响应Touch事件,而且不会影响滚动拖拽的bouncing。
如果需要touch的个数或者坐标,也很简单,不过需要自己修改代码里的JavaScript。
- - (void)viewDidLoad {
- [super viewDidLoad];
- selfself.webView.delegate=self;
- NSString *resourcePath = [ [NSBundle mainBundle] resourcePath];
- NSString *filePath = [resourcePath stringByAppendingPathComponent:@"test.html"];
- NSString *htmlstring=[[NSString alloc] initWithContentsOfFile:filePath encoding:NSUTF8StringEncoding error:nil];
- NSString *newHTMLString=[htmlstring stringByAppendingString:@"<script language=\"javascript\">
- document.ontouchstart=function(){
- document.location=\"myweb:touch:start\"; };
- document.ontouchend=function(){
- document.location=\"myweb:touch:end\";
- };
- document.ontouchmove=function(){
- document.location=\"myweb:touch:move\";
- }
- </script>"
- ];
- [self.webView loadHTMLString:newHTMLString baseURL:[NSURL fileURLWithPath:[[NSBundle mainBundle] bundlePath]]];
- [htmlstring release];
- }
- - (BOOL)webView:(UIWebView*)webView shouldStartLoadWithRequest:(NSURLRequest*)
- request navigationType:(UIWebViewNavigationType)navigationType {
- NSString *requestString = [[request URL] absoluteString];
- NSArray *components = [requestString componentsSeparatedByString:@":"];
- if ([components count] > 1 && [(NSString *)[components objectAtIndex:0] isEqualToString:@"myweb"]) {
- if([(NSString *)[components objectAtIndex:1] isEqualToString:@"touch"])
- {
- NSLog(@"%@",[components objectAtIndex:2]);
- }
- return NO;
- }
- return YES;
- }
