QuickTime播放器UIWebView上的iOS 9在播放按下後發出警告

Question

當頁面加載時，我想在UIWebView（iOS 9.2.1）上播放m3u8鏈接時按下時會出現quickTime播放器的播放圖標（僅限於iPhone設備）玩家填滿所有的屏幕和日誌給出了這樣的警告：

This application is modifying the autolayout engine from a background thread, which can lead to engine corruption and weird crashes. This will cause an exception in a future release.

這不會對任何iPad設備僅適用於iPhone的人出現。

即使試圖在一個「瘦」應用程序仍然相同的警告，我用在UIWebView中的負載要求：

dispatch_async(dispatch_get_main_queue(), ^{ 
    NSString *rec = [_m3u8 string"]; 
    NSURL *url = [NSURL URLWithString:rec]; 
    NSURLRequest *request = [NSURLRequest requestWithURL:url]; 
    self.WebView.allowsInlineMediaPlayback = YES; 
    [self.WebView loadRequest:request]; 
}); 

由於任何人誰幫助。

Answer 1

好還是不UIWebView的很成功但有一個名爲「WKWebView」的對象是<WebKit/WebKit.h>的一部分來實現：

#import <WebKit/WebKit.h> 

然後在您的viewDidLoad等初始化：

WKWebView *w = [[WKWebView alloc]initWithFrame:self.view.bounds]; 
NSURL *url = [NSURL URLWithString:@"yourLink.m3u8"]; 
NSURLRequest *request = [NSURLRequest requestWithURL:url]; 
[w loadRequest:request]; 
[self.view addSubview:w]; 

還有一件事添加到您的.plist文件中：

App Transport Security Settings - Dictionary。

允許任意加載= YES。

它比UIWebView快得多，我沒有在日誌中看到上面提到的警告。

乾杯。
