推荐答案
将此文件放入头文件中:
put this into your header file:
@interface YourViewController : UIViewController <UIAlertViewDelegate>
将此信息添加到课程中并附上提醒:
put this into the class with your alert:
- (void)alertOKCancelAction {
// open a alert with an OK and cancel button
UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"Open?" message:@"Open Website?" delegate:self cancelButtonTitle:@"Cancel" otherButtonTitles:@"Open", nil];
alert.tag = 1;
[alert show];
[alert release];
}
添加此方法:
- (void)alertView:(UIAlertView *)alert clickedButtonAtIndex:(NSInteger)buttonIndex
{
// the user clicked one of the OK/Cancel buttons
if(alert.tag == 1)
{
if(buttonIndex == alert.cancelButtonIndex)
{
NSLog(@"cancel");
}
else
{
NSLog(@"ok");
[[UIApplication sharedApplication] openURL:[NSURL URLWithString: @"http://www.google.com"]];
}
}
}
