IOS 中弹框的实现方法整理
#define iOS8Later ([UIDevice currentDevice].systemVersion.doublevalue >= 8.0)
ios 8以前的弹框
@interface RootViewController ()@end
UIalertView * alert = [[UIalertView alloc] initWithTitle:@"登陆失败" message:@"请重新输入用户名和密码" delegate:self cancelButtonTitle:@"取消" otherButtonTitles:@"确定", nil];
[alert show];
#pragma mark - UIalertView Delegate Methods -
- (void)alertView:(UIalertView *)alertView clickedButtonAtIndex:(NSInteger)buttonIndex
{
if(buttonIndex == 0)
{
NSLog(@"点击取消按钮后,想要的操作,可以加此处");
}
else if(buttonIndex == 1)
{
NSLog(@"点击确定按钮后,想要的操作,可以加此处");
}
}
ios8以后的弹框
UIalertController *_alertVC = [UIalertController alertControllerWithTitle:@"登陆失败" message:@"请重新输入用户名和密码" preferredStyle:UIalertControllerStylealert];
//警告类型,红色字体 UIalertActionStyleDestructive
// UIalertAction *_doAction = [UIalertAction actionWithTitle:@"确定" style:UIalertActionStyleDestructive handler:nil];
// [_alertVC addAction:_doAction];
UIalertAction *_doAction = [UIalertAction actionWithTitle:@"确定" style:UIalertActionStyleDefault handler:^(UIalertAction * _Nonnull action)
{
NSLog(@"点击确定按钮后,想要的操作,可以加此处");
}];
[_alertVC addAction:_doAction];
// UIalertAction *_cancleAction = [UIalertAction actionWithTitle:@"取消" style:UIalertActionStyleCancel handler:nil];
// [_alertVC addAction:_cancleAction];
UIalertAction *_cancleAction = [UIalertAction actionWithTitle:@"取消" style:UIalertActionStyleCancel handler:^(UIalertAction * _Nonnull action)
{
NSLog(@"点击取消按钮后,想要的操作");
}];
[_alertVC addAction:_cancleAction];
[self presentViewController:_alertVC animated:YES completion:nil];
//警告类型,红色字体 UIalertActionStyleDestructive,如下图所示的效果
UIalertAction *_doAction = [UIalertAction actionWithTitle:@"确定" style:UIalertActionStyleDestructive handler:nil];
[_alertVC addAction:_doAction];
