iOS随笔小记--openURL(打电话、发短信、打开链接)

1.打电话

UIApplication *app = [UIApplication sharedApplication];

[app openURL:[åNSURL URLWithString:@"tel://10086"]];

2.发短信

[app openURL:[NSURL URLWithString:@"sms://10086"]];

3.发邮件

[app openURL:[NSURL URLWithString:@"mailto://447640819@qq.com"]];

4.打开一个网页资源

[app openURL:[NSURL URLWithString:@"http://m.baidu.com"]];

5.可以通过设置UIApplication的idleTimerDisabled属性来指定iOS是否锁频：

// 禁用休闲时钟

[[UIApplication sharedApplication] setIdleTimerDisabled: YES];

[UIApplication sharedApplication].idleTimerDisabled = YES;
