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 ()<UIAlertViewDelegate> @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];
