iOS开发中Date Picker和UITool Bar控件的使用简介

get1Button.width = 50; 

[myToolBarItems addObject:myButton];      

C>加一个文本Label
复制代码
view plaincopy to clipboardprint?

 

UILabel *myLabel = [[UILabel alloc] initWithFrame:CGRectMake(40.0f, 20.0f, 45.0f, 10.0f)]; 

myLabel.font=[UIFont systemFontOfSize:10]; 

//myLabel.backgroundColor = [UIColor clearColor]; 

//myLabel.textAlignment=UITextAlignmentCenter; 

UIBarButtonItem *myButtonItem = [[UIBarButtonItem alloc]initWithCustomView:myLabel]; 

[myToolBarItems addObject: myButtonItem];    

[mylabel release]; 

[myButtonItem release];  

 

 

D>加一个进度条UIProgressView

复制代码
UIProgressView *myProgress = [[UIProgressView alloc] initWithFrame:CGRectMake(65.0f, 20.0f, 90.0f, 10.0f)]; 

 

UIBarButtonItem *myButtonItem = [[UIBarButtonItem alloc]initWithCustomView:myProgress]; 

[myToolBarItems addObject: myButtonItem]; 

[myProgress release];                                            

[myButtonItem release];  

可以加使用initWithCustomView制作各种button，这里就不在这里一个一个在加了。我想你应该也已经掌握了如何添加各种buttonItem的方法了。
