在iphone中以uibutton programmaticaly添加图像

Question

我是iphone开发的新手.我试图用图像开发按钮(当我点击按钮时图像会显示)这个应用程序将像iphone中的programmaticaly一样开发.

任何人都可以帮我解决我的问题.

先感谢您.

做这个:

UIImage *newButtonImage = [UIImage imageNamed:@"imageInMyProject.png"];
//Create image object from bundle. Name must include filetype; is case sensetive.

[myButton setImage:newButtonImage forState:UIControlStateNormal];
 //Set the image for the button when it is in it's default state. 

这种做事方式很棒,因为您可以根据需要将图像设置为不同的显示方式.可以在此处找到不同的UIControlStates:http://developer.apple.com/library/ios/#documentation/uikit/reference/UIControl_Class/Reference/Reference.html#//apple_ref/c/tdef/UIControlState

快乐编码:)
