webview里拦截url

requesting是url的absultestring

if ([requestString containsString:@"weixin://"]) {//支付宝是alipays://

NSRange range = [requestString rangeOfString:@"weixin://"]; //截取的字符串起始位置

NSString * resultStr = [requestString substringFromIndex:range.location]; //截取字符串

NSURL *weixinURL = [NSURL URLWithString:resultStr];

[[UIApplication sharedApplication] openURL:weixinURL options:@{UIApplicationOpenURLOptionUniversalLinksOnly: @NO} completionHandler:^(BOOL success) {

}];

}
