iOS uiwebview 大小跟隨內容自適應
- (void)viewDidLoad {
[superviewDidLoad];
// Do any additional setup after loading the view, typically from a nib.
NSString *str=@"<body><div id='webview_content_wrapper'>jhkhkjhkjhk<img src='f_static_002.gif' style='width=14px;height=14px;'>jhkjjhkh kjhkjhk<img src='f_static_002.gif' style='width=14px;height=14px;'>jhk jjhkhk jhkjhk<img src='f_static_002.gif' style='width=14px;height=14px;'>jhkjhj</div></body>";
[_webloadHTMLString:str baseURL:[NSURLfileURLWithPath:[[NSBundlemainBundle] resourcePath] ]];
_web.scrollView.bounces = NO;
_web.scrollView.showsHorizontalScrollIndicator = NO;
_web.scrollView.scrollEnabled = NO;
// _web.delegate=self;
[_websizeToFit];
dispatch_after(dispatch_time(
// [_web sizeToFit];
_web.frame=CGRectMake(0, 0, _web.frame.size.width, 1);
CGSize s=[_web sizeThatFits:CGSizeZero];
NSLog(@"%g %g ",s.width,s.height);
CGRect r=_web.frame;
NSLog(@"%g %g %g %g"
r.size=s;
_web.frame=r;
NSLog(@"%g %g %g %g",r.origin.x,r.origin.y,r.size.width,r.size.height);
self.view.backgroundColor=[UIColorblueColor];
});
}
也可以在webViewDidFinishLoad:(UIWebView *)webView用延後執行的效果。不過這個經常不準
