  • ios文本、键盘、按钮的练习

    一.贴图为快

    二.知识点

    1.文本

    2.键盘

     1>自动隐藏,方法1:Did End on Exit事件,添加hideKeyboard方法,调用resignFirstResponder让让输入对象放弃其获取输入的权利;

                       方法2:(主要针对数字键盘)触摸背景来隐藏键盘。

     2>Keyboard属性,默认,Number Pad,Email Address等。

    3.按钮

     1>给按钮添加背景图片,在视图加载时设置,

    - (void)viewDidLoad{

    //在视图加载时设置按钮模板
    UIImage *normalImage = [[UIImage imageNamed:@"whiteButton.png"] stretchableImageWithLeftCapWidth:12.0 topCapHeight:0.0];
    UIImage *pressedImage = [[UIImage imageNamed:@"blueButton.png"] stretchableImageWithLeftCapWidth:12.0 topCapHeight:0.0];
    [self.theButton setBackgroundImage:normalImage forState:UIControlStateNormal];

    [super viewDidLoad];

    [self.theButton setBackgroundImage:pressedImage forState:UIControlStateHighlighted];

    }

    2>createStory方法

    self.theStory.text=[self.theTemplate.text stringByReplacingOccurrencesOfString:@"<place>" withString:self.thePlace.text];
    self.theStory.text=[self.theStory.text stringByReplacingOccurrencesOfString:@"<verb>" withString:self.theVerb.text];
    self.theStory.text=[self.theStory.text stringByReplacingOccurrencesOfString:@"<number>" withString:self.theNumber.text];
