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];
