Objective-C: [Common] _BSMachErr

最近发现在使用拨打电话时

 [[UIApplication sharedApplication] openURL:[NSURL URLWithString:@"tel:1231230123"]];

发现点击取消会报下面这个警告

[Common] _BSMachError: port 6b17; (os/kern) invalid capability (0x14) "Unable to insert COPY_SEND"

解决方法

dispatch_async(dispatch_get_global_queue(DISPATCH_QUEUE_PRIORITY_DEFAULT, 0), ^{
     [[UIApplication sharedApplication] openURL:[NSURL URLWithString:@"tel:1231230123"]];  
 });
