按钮的代码就不写了。直接写主要代码。
<key>LSApplicationQueriesSchemes</key>
<array>
<string>tel</string>
<string>telprompt</string>
</array>
plist里加上述代码就是意思申请打电话权限
-(void)callPhoneStr:(NSString*)phoneStr {
NSString *str2 = [[UIDevicecurrentDevice] systemVersion];
if ([str2compare:@"10.2"options:NSNumericSearch] ==NSOrderedDescending || [str2compare:@"10.2"options:NSNumericSearch] ==NSOrderedSame)
{
NSLog(@">=10.2");
NSString* PhoneStr = [NSStringstringWithFormat:@"tel://%@",phoneStr];
if ([PhoneStrhasPrefix:@"sms:"] || [PhoneStrhasPrefix:@"tel:"]) {
UIApplication * app = [UIApplicationsharedApplication];
if ([appcanOpenURL:[NSURLURLWithString:PhoneStr]]) {
[app openURL:[NSURLURLWithString:PhoneStr ]options:@{}completionHandler:nil ];
}
}
}else {
NSMutableString* str1 = [[NSMutableStringalloc]initWithString:phoneStr];//存在堆区，可变字符串
NSString * str = [NSStringstringWithFormat:@"是否拨打电话\n%@",str1];
UIAlertController *alert = [UIAlertControlleralertControllerWithTitle:strmessage: nilpreferredStyle:UIAlertControllerStyleAlert];
[alert addAction:[UIAlertActionactionWithTitle:@"呼叫"style:UIAlertActionStyleDestructivehandler:^(UIAlertAction *action) {
NSLog(@"点击了呼叫按钮10.2下");
NSString* PhoneStr = [NSStringstringWithFormat:@"tel://%@",phoneStr];
if ([PhoneStrhasPrefix:@"sms:"] || [PhoneStrhasPrefix:@"tel:"]) {
UIApplication * app = [UIApplicationsharedApplication];
if ([appcanOpenURL:[NSURLURLWithString:PhoneStr]]) {
[app UIApplication:[NSURLURLWithString:PhoneStr]];
}
}
}]];
[alert addAction:[UIAlertActionactionWithTitle:@"取消"style:UIAlertActionStyleCancelhandler:^(UIAlertAction *action) {
NSLog(@"点击了取消按钮");
}]];
[selfpresentViewController:alertanimated:YEScompletion:nil];
}
}
一定要区分一下ios系统版本，因为api是不一样的，因为版本不一样，方法是不一样的。10.2那个里面的方法自己可以弹出一个弹出框，另外一个需要用UIAlertController来制作弹出框。
