An component WebView for ios
PAWeView is an extensible WebView which is built on top of WKWebView, the modern WebKit framework debuted in iOS 8.0. It provides fast Web for developing sophisticated iOS native or hybrid applications.
For a complete example on how to use PAWeView, see the Sample Project.
- Deployment: iOS 8.0
- #import "PAWebView.h"

//初始化单例 PAWebView *webView = [PAWebView shareInstance]; //加载网页 [webView loadRequestURL:[NSMutableURLRequest requestWithURL:[NSURL URLWithString:@"https://www.sina.cn"] cachePolicy:NSURLRequestReloadIgnoringLocalCacheData timeoutInterval:20.0f]]; [self.navigationController pushViewController:webView animated:YES]; //缓存沿用了 NSURLRequest 的缓存机制，用户可以自定义设置； typedef NS_ENUM(NSUInteger, NSURLRequestCachePolicy) { NSURLRequestUseProtocolCachePolicy = 0, //默认的缓存策略 NSURLRequestReloadIgnoringLocalCacheData = 1, //忽略缓存，从服务端加载数据； NSURLRequestReloadIgnoringLocalAndRemoteCacheData = 4, // Unimplemented NSURLRequestReloadIgnoringCacheData = NSURLRequestReloadIgnoringLocalCacheData, NSURLRequestReturnCacheDataElseLoad = 2, NSURLRequestReturnCacheDataDontLoad = 3, NSURLRequestReloadRevalidatingCacheData = 5, // Unimplemented }; - Refress
//重新加载网页
[webView reload];
//无视缓存，重新加载服务器最新的网
[webView reloadFromOrigin];
- JS->Native
/* messageHander实现JS调用Native */
- (void)addMessageHander
{
//注入交互事件，实现 PAWKScriptMessageHandler 代理
[webView addScriptMessageHandlerWithName:@[@"AliPay",@"weixin"]];
//通过block的形式实现
[webView addScriptMessageHandlerWithName:@[@"AliPay",@"weixin"] observeValue:^(WKUserContentController *userContentController, WKScriptMessage *message) {
//JS调用OC处理
NSLog(@"name:%@;body:%@",message.name,message.body);
}];
}
/* 实现 PAWKScriptMessageHandler 代理 */
- (void)PAUserContentController: (WKUserContentController *) userContentController didReceiveScriptMessage:(WKScriptMessage *)message{
//JS调用OC处理
NSLog(@"name:%@;body:%@",message.name,message.body);
}
- Native -> JS
//方式一、
[[PAWebView shareInstance] callJS:@"alert('调用JS成功')"];
//方式二、
[[PAWebView shareInstance] callJS:@"alert('调用JS成功')" handler:^(id response, NSError *error) {
NSLog(@"调用js回调事件");
}];
