iOS app调用打电话功能

赶着下班就不多说了， 初始化 UIWebView 名为 _phoneCallWebView，调用如下方法，注意下方 红色区域

#pragma mark -----打电话-------------

- (void)openPhoneCallViewWithphoneNumber:(NSString *)phoneNum

{

if (_phoneCallWebView == nil) {

_phoneCallWebView = [[UIWebView alloc] initWithFrame:CGRectZero];

}

NSString *newPhoneString = [要调用打电话功能的ViewController dealWithPhoneNumber:phoneNum];

if ([要调用打电话功能的ViewController isMobileNumber:newPhoneString]) {

NSURL* dialUrl = [NSURL URLWithString:[NSString stringWithFormat:@"tel:%@", newPhoneString]];

if ([[UIApplication sharedApplication] canOpenURL:dialUrl])

{

if (_phoneCallWebView) {

[_phoneCallWebView loadRequest:[NSURLRequest requestWithURL:dialUrl]];

}

else{

[[UIApplication sharedApplication] openURL:dialUrl];

}

}

else

{

UIAlertController *alert = [UIAlertController alertControllerWithTitle:@"温馨提示" message:@"设备不支持"
preferredStyle:UIAlertControllerStyleAlert];

UIAlertAction *cacelAction = [UIAlertAction actionWithTitle:@"确定" style:UIAlertActionStyleCancel handler:nil];

[alert addAction:cacelAction];

[self presentViewController:alert animated:YES completion:nil];

alert = nil;

}

} else {

UIAlertController *alert = [UIAlertController alertControllerWithTitle:@"温馨提示" message:@"您选择的号码不合法"
preferredStyle:UIAlertControllerStyleAlert];

UIAlertAction *cacelAction = [UIAlertAction actionWithTitle:@"确定" style:UIAlertActionStyleCancel handler:nil];

[alert addAction:cacelAction];

[self presentViewController:alert animated:YES completion:nil];

alert = nil;

}

}
