是否可以动态创建UITextView？

Question

例如:触摸事件发生时将创建UITextView.

怎么做？

谢谢

Answer 1

您必须以编程方式执行此操作,我不认为这在Interface Builder中是可行的.

做一些像

UITextView *myTextView = [[UITextView alloc] init];
myTextView.text = @"some text";
//some other setup like setting the font for the UITextView...
[self addSubview:myTextView];
[myTextView sizeToFit];

在您查看的适当方法(例如- (void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event)或您的视图控制器.

Answer 2

UITextView*txtview =
    [[UITextView alloc]initWithFrame:CGRectMake(x,y,width,hight)];  
[txtview setDelegate:self];    
[txtview setReturnKeyType:UIReturnKeyDone];    
[txtview setTag:1];    
[txtview setCornerRadius:5];    
[self.scrollview txtview];
