我试图打开应用程序“计算器”,但我不知道该计划计算器的计划是什么?
- (IBAction)btnColetorClick:(id)sender
{
NSString *customURL = @"calculator://";
if ([[UIApplication sharedApplication] canOpenURL:[NSURL URLWithString:customURL]])
{
[[UIApplication sharedApplication] openURL:[NSURL URLWithString:customURL]];
}
else
{
UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"URL error"
message:[NSString stringWithFormat:@"No custom URL defined for %@", customURL]
delegate:self
cancelButtonTitle:@"Ok"
otherButtonTitles:nil];
[alert show];
}
}
