当我们编辑UITextField时，移动带有一些UITextFields的UIView

Question

我有一个UIView。里面，我有两个文本字段 - username和password，和一个submit UIButton。我把我的UIView放在屏幕的中心。所以现在当我编辑我的username and password field时，我的密码字段被键盘隐藏了。

所以当我的键盘打开时，可以显示我的“带有这两个文本字段的全部UIView”？

请帮助一些code.Thanks！

更新的代码：

@implementation ViewController 
@synthesize scrollView; 


- (void)viewDidLoad { 
    [super viewDidLoad]; 
    // Do any additional setup after loading the view, typically from a nib. 
} 

- (void)didReceiveMemoryWarning { 
    [super didReceiveMemoryWarning]; 
    // Dispose of any resources that can be recreated. 
} 
-(void)textFieldDidBeginEditing:(UITextField *)textField { 
    self.scrollView.contentSize = CGSizeMake(self.scrollView.contentSize.width, (self.scrollView.contentSize.height + 260)); 
    self.scrollView.contentOffset = CGPointMake(0,120); 
} 

-(void)textFieldDidEndEditing:(UITextField *)textField { 
    self.scrollView.contentOffset = CGPointZero; 
    self.scrollView.contentSize = CGSizeMake([UIScreen mainScreen].bounds.size.width, [UIScreen mainScreen].bounds.size.height); 
}

更改UIView到UIScrollView。然后在textFieldDidBeginEditing方法中将键盘高度（通常为260）添加到您的滚动视图的contentSize并相应地更改contentOffset。不要忘了复位contentSize和contentOffset回到正常值textFieldDidEndEditing

-(void)textFieldDidBeginEditing:(UITextField *)textField { 
    self.scrollView.contentSize = CGSizeMake(self.scrollView.contentSize.width, (self.scrollView.contentSize.height + 260)); 
    self.scrollView.contentOffset = CGPointMake(0, <desired height>); 
} 

-(void)textFieldDidEndEditing:(UITextField *)textField { 
    self.scrollView.contentOffset = CGPointZero; 
    self.scrollView.contentSize = CGSizeMake([UIScreen mainScreen].bounds.size.width, [UIScreen mainScreen].bounds.size.height); 
}
