需要注意的是立磁，iOS9以上的系統(tǒng)需要在info.plist添加白名單
<key>LSApplicationQueriesSchemes</key>
<array>
<string>wechat</string>
<string>weixin</string>
<string>alipay</string>
<string>alipayshare</string>
<string>mqq</string>
</array>
if([[UIApplication sharedApplication] canOpenURL:[NSURL URLWithString:@"mqq://"]])
{
NSString *QQ = @"1099779883";
//調(diào)用QQ客戶端,發(fā)起QQ臨時會話
NSString *url = [NSString stringWithFormat:@"mqq://im/chat?chat_type=wpa&uin=%@&version=1&src_type=web",QQ];
[[UIApplication sharedApplication] openURL:[NSURL URLWithString:url]];
}
else{
UIAlertView * alert = [[UIAlertView alloc] initWithTitle:@"溫馨提示" message:@"手機(jī)未安裝QQ" delegate:self cancelButtonTitle:@"確定" otherButtonTitles:nil, nil];
[alert show];
}
