嗨,大家好,我将此IBAction链接到一个按钮:
- (IBAction)showCurl:(id)sender {
alert1 = [[UIAlertView alloc]initWithTitle:@"Loading" message:nil delegate:self cancelButtonTitle:nil otherButtonTitles:nil];
[alert1 show];
}
和一个clickedButtonIndex自动运行,但是不知何故它不会加载SecondViewController:
#pragma mark UIAlertView
- (void)alertView:(UIAlertView *)alert1 clickedButtonAtIndex:(NSInteger)buttonIndex {
if(buttonIndex == 0){
SecondViewController *sampleView = [[SecondController alloc] init];
[sampleView setModalTransitionStyle:UIModalTransitionStylePartialCurl];
[self presentModalViewController:sampleView animated:YES];
}
else{
// Cancel prompt
}
}
我在这里想念什么吗?
最佳答案
如果您没有为警报视图提供某些按钮标题,则不会有任何按钮可以点击,并且不会调用该委托方法。
- (IBAction)showCurl:(id)sender {
alert1 = [[UIAlertView alloc] initWithTitle:@"Loading" message:nil delegate:self cancelButtonTitle:@"OK" otherButtonTitles:nil];
[alert1 show];
}
关于objective-c - clickedButtonAtIndex:不起作用,我们在Stack Overflow上找到一个类似的问题:https://stackoverflow.com/questions/10435632/
