iOS 拨打系统电话弹窗延迟问题

iOS10.0后拨打系统电话延迟现象严重；
点击查看openURL方法查看

- (BOOL)openURL:(NSURL*)url NS_DEPRECATED_IOS(2_0, 10_0, "Please use openURL:options:completionHandler: instead") 

iOS10.0后让我们用openURL:options:completionHandler:代替；

上代码

方法一：

if (_telPhone.length == 0) {
return;
            }
NSString *callPhone = [NSString stringWithFormat:@"telprompt://%@", _telPhone];
CGFloat version = [[[UIDevice currentDevice]systemVersion]floatValue];
if (version >= 10.0) {
/// 大于等于10.0系统使用此openURL方法
                [[UIApplication sharedApplication] openURL:[NSURL URLWithString:callPhone] options:@{} completionHandler:nil];
            } else {
                [[UIApplication sharedApplication] openURL:[NSURL URLWithString:callPhone]];
            }

方法二：也可以写个线程

if (_telPhone.length == 0) {  
return;  
    }  
    NSString *callPhone = [NSString stringWithFormat:@"telprompt://%@", _telPhone];  
    dispatch_async(dispatch_get_global_queue(0, 0), ^{  
[[UIApplication sharedApplication] openURL:[NSURL URLWithString:callPhone]];  
    });
