openUrl
开发中使用以下代码可以实现快速拨打电话
NSString* phoneVersion = [[UIDevice currentDevice] systemVersion];
if
(phoneVersion.floatValue < 10.0) {
//iOS10 以前使用
[[UIApplication sharedApplication] openURL:[NSURL URLWithString:@
"[Tel://123456](tel://123456)"
]];
}
else
{
//iOS10 以后使用
[[UIApplication sharedApplication] openURL:[NSURL URLWithString:@
"[Tel://123456](tel://123456)"
]
options:@{}
completionHandler:nil];
}
只要给出对应的URL，系统就可以直接跳：
//拨打电话
[NSURL URLWithString:@
"[tel://123456](tel://123456)"
]
//发送短信
[NSURL URLWithString:@
"[sms://123456](sms://123456)"
