UIAlertView带有文本字段和ios 6中的三个按钮问题 [英] UIAlertView with textfield and three buttons issue in ios 6

问题描述

     UIAlertView* alert = [[UIAlertView alloc] initWithTitle:@"Enter Student Name"        message:nil delegate:self cancelButtonTitle:@"Cancel" otherButtonTitles:@"Save", @"Save and Add", nil];
                alert.tag = 1;
                alert.transform=CGAffineTransformMakeScale(1.0, 0.75);
                alert.alertViewStyle=UIAlertViewStylePlainTextInput;
                [alert show];

-(void)willPresentAlertView:(UIAlertView *)alertView {

    if (alertView.tag == 1) {


        for (UIView *view in alertView.subviews) {
            if ([view isKindOfClass:[UITextField class]]||
                [view isKindOfClass:[UIButton class]] || view.frame.size.height==31) {
                CGRect rect=view.frame;
                rect.origin.y += 65;
                view.frame = rect;
            }
        }

    }


}

因为我正在使用textfield和三个按钮显示alertview，它在ios 7中工作正常，但在ios 6中没有。
查看两个ios图片 - >

As i am showing alertview with textfield and three buttons its working fine in ios 7 but not in ios 6 . have a look at both ios images -- >

因为你们都可以看到ios 6的警报视图受到干扰......但我没有得到我在那里做错了什么。

as you all can see the alertview of ios 6 is disturbed ... but i am not getting what i am doing wrong there .

推荐答案

试试此代码

  UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"Enter Student Name"
                                                message:@""
                                               delegate:self
                                      cancelButtonTitle:@"Cancel"
                                      otherButtonTitles:@"Save",@"Save & Add",nil];

alert.alertViewStyle = UIAlertViewStylePlainTextInput;
[alert show];



-(void)willPresentAlertView:(UIAlertView *)alertView {

if ([[[UIDevice currentDevice] systemVersion] floatValue] <7) 

   {
    [alertView setFrame:CGRectMake(17, 30, 286, 280)];
    NSArray *subviewArray = [alertView subviews];
    UILabel *message = (UILabel *)[subviewArray objectAtIndex:2];
    [message setFrame:CGRectMake(10, 46, 260, 20)];
    UIButton *cancelbutton = (UIButton *)[subviewArray objectAtIndex:3];
    [cancelbutton setFrame:CGRectMake(10, 125, 260, 42)];
    UIButton *savebutton = (UIButton *)[subviewArray objectAtIndex:4];
    [savebutton setFrame:CGRectMake(10, 170, 260, 42)];
    UIButton *saveAddbutton = (UIButton *)[subviewArray objectAtIndex:5];
    [saveAddbutton setFrame:CGRectMake(10, 220, 260, 42)];
    UITextField *textfield = (UITextField *)[subviewArray objectAtIndex:6];
    [textfield setFrame:CGRectMake(10, 80, 266, 50)];
    UITextField *placeTF = (UITextField *)[subviewArray objectAtIndex:7];
    [placeTF setFrame:CGRectMake(15, 70, 256, 50)];
   }

}

对于轮换问题，请使用此代码

For rotation problem use this code

- (void)didRotateFromInterfaceOrientation:(UIInterfaceOrientation)fromInterfaceOrientation{
if (UIInterfaceOrientationPortrait == UIInterfaceOrientationIsPortrait(fromInterfaceOrientation))
{
           [alert setFrame:CGRectMake(100, 10, 286, 320)];
    NSArray *subviewArray = [alert subviews];
    UILabel *messageLB = (UILabel *)[subviewArray objectAtIndex:2];
    [messageLB setFrame:CGRectMake(10, 46, 260, 20)];
    UIButton *cancelBT = (UIButton *)[subviewArray objectAtIndex:3];
    [cancelBT setFrame:CGRectMake(10, 125, 260, 42)];
    UIButton *okBT = (UIButton *)[subviewArray objectAtIndex:4];
    [okBT setFrame:CGRectMake(10, 170, 260, 42)];
    UIButton *searchBT = (UIButton *)[subviewArray objectAtIndex:5];
    [searchBT setFrame:CGRectMake(10, 220, 260, 42)];
    UITextField *plateTF = (UITextField *)[subviewArray objectAtIndex:6];
    [plateTF setFrame:CGRectMake(10, 80, 266, 50)];
    UITextField *placeTF = (UITextField *)[subviewArray objectAtIndex:7];
    [placeTF setFrame:CGRectMake(15, 70, 256, 50)];


}
else{

    [alert setFrame:CGRectMake(17, 30, 286, 280)];
    NSArray *subviewArray = [alert subviews];
    UILabel *messageLB = (UILabel *)[subviewArray objectAtIndex:2];
    [messageLB setFrame:CGRectMake(10, 46, 260, 20)];
    UIButton *cancelBT = (UIButton *)[subviewArray objectAtIndex:3];
    [cancelBT setFrame:CGRectMake(10, 125, 260, 42)];
    UIButton *okBT = (UIButton *)[subviewArray objectAtIndex:4];
    [okBT setFrame:CGRectMake(10, 170, 260, 42)];
    UIButton *searchBT = (UIButton *)[subviewArray objectAtIndex:5];
    [searchBT setFrame:CGRectMake(10, 220, 260, 42)];
    UITextField *plateTF = (UITextField *)[subviewArray objectAtIndex:6];
    [plateTF setFrame:CGRectMake(10, 80, 266, 50)];
    UITextField *placeTF = (UITextField *)[subviewArray objectAtIndex:7];
    [placeTF setFrame:CGRectMake(15, 70, 256, 50)];

}
}
