Solution iOS phone prompt box response slow

Add a class method, and then call directly

+ (void) Callphonestr: (nsstring*) phonestr WITHVC: (Uiviewcontroller *) selfvc{if (Phonestr.length >=) {NSString *
STR2 = [[Uidevice currentdevice] systemversion]; if ([str2 compare:@ "10.2" options:nsnumericsearch] = = Nsordereddescending | | [Str2 compare:@ "10.2" options:nsnumericsearch] = = nsorderedsame) {nsstring* phonestr = [NSString stringwithformat:@]
telprompt://%@ ", Phonestr]; [[UIApplication sharedapplication] Openurl:[nsurl urlwithstring:phonestr] options:@{} completionHandler:^ (BOOL

Success) {NSLog (@ "phone success");  }else {nsmutablestring* str1 = [[nsmutablestring alloc]initwithstring:phonestr];//exists heap area, variable string if (Phonestr.length = 10) {[Str1 insertstring:@ "-" atindex:3];//inserts a string into one of the other strings [str1 insertstring:@ "-" atindex:7];// Inserts a string into one of the other strings}else {[str1 insertstring:@ "-" atindex:3];//inserts a string into one of the other strings [str1 insertstring:@ "-"

Set PopOver to point to item alert.popoverPresentationController.barButtonItem = Selfvc.navigationItem.leftBarButtonItem; Add button [Alert addaction:[uialertaction actionwithtitle:@ ' call ' style:uialertactionstyledestructive handler:^ (
