openUrl

開發(fā)中使用以下代碼可以實現(xiàn)快速撥打電話
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];

}
