NSAlert 警告提示窗有以下两种方式展示：
- (IBAction)alertButton:(id)sender {
NSString *title1 =NSLocalizedString(@"Ok", nil);//本地化添加一个Localizable.string文件
NSString *title2 =NSLocalizedString(@"Cancel", nil);
NSString *messagetext =NSLocalizedString(@"messagetext3", nil);
NSString *informativetext =NSLocalizedString(@"Please select the day or the latest", nil);
[self alertSheetFirstBtnTitle:title1 SecondBtnTitle:title2 MessageText:messagetext InformativeText:informativetext];
}
//卷帘式对话框alert：
-(void)alertSheetFirstBtnTitle:(NSString *)firstname SecondBtnTitle:(NSString *)secondname MessageText:(NSString *)messagetext InformativeText:(NSString *)informativetext{
NSAlert *alert = [[NSAlert alloc] init];
[alert addButtonWithTitle:firstname];
[alert addButtonWithTitle:secondname];
// [alert addButtonWithTitle:@"chenglibin1"];//可以添加三个按钮
[alert setMessageText:messagetext];
[alert setInformativeText:informativetext];
[alert setAlertStyle:NSWarningAlertStyle];
[alert beginSheetModalForWindow:self.window completionHandler:^(NSInteger result) {
if (result == NSAlertFirstButtonReturn) {//响应第一个按钮被按下：name：firstname；
//...
NSLog(@"Ok");
}
if (result == NSAlertSecondButtonReturn) {
NSLog(@"Cancel");
}
if (result == NSAlertThirdButtonReturn) {
NSLog(@"chenglibin1");
}
}];
}
//nsalert 采用Modal Window 的方式展示：
-(void)alertModalFirstBtnTitle:(NSString *)firstname SecondBtnTitle:(NSString *)secondname MessageText:(NSString *)messagetext InformativeText:(NSString *)informativetext{
NSAlert *alert = [[NSAlert alloc] init];
[alert addButtonWithTitle:firstname];
[alert addButtonWithTitle:secondname];
// [alert addButtonWithTitle:@"chenglibin1"];//可以添加三个按钮
[alert setMessageText:messagetext];
[alert setInformativeText:informativetext];
[alert setAlertStyle:NSWarningAlertStyle];
NSUInteger action = [alert runModal];
//响应window的按钮事件
if(action == NSAlertFirstButtonReturn)
{
NSLog(@"defaultButton clicked!");
}
else if(action == NSAlertSecondButtonReturn )
{
NSLog(@"alternateButton clicked!");
}
else if(action == NSAlertThirdButtonReturn)
{
NSLog(@"otherButton clicked!");
}
}
