執(zhí)行webview 的 stringByEvaluatingJavaScriptFromString 方法 報(bào)錯(cuò) ,
Thread 12: EXC_BREAKPOINT (code=1, subcode=0x1d3f11964)
原因:
// 創(chuàng)建隊(duì)列組，可以使多個(gè)網(wǎng)絡(luò)請(qǐng)求異步執(zhí)行，執(zhí)行完之后再進(jìn)行操作
dispatch_group_t group = dispatch_group_create();
//創(chuàng)建全局隊(duì)列
dispatch_queue_t queue = dispatch_get_global_queue(0, 0);
dispatch_group_async(group, queue, ^{
//不能執(zhí)行 stringByEvaluatingJavaScriptFromString,猜測(cè)stringByEvaluatingJavaScriptFromString是個(gè)同步方法,不能被執(zhí)行
});
