rightView UITextField的位置 [英] Position of rightView UITextField

问题描述

有没有办法在UITextField上调整rightView的位置？我尝试在视图上设置框架（设置为rightView）但它没有改变任何东西。

Is there a way to adjust the position of a rightView on UITextField? I tried setting the frame on the view (set as rightView) but it didn't change anything.

我想避免制作两个视图，一个作为右视图如果可能的话，一个作为rightView的子视图，我更改子视图的位置。

I'd like to avoid making two views, one as the rightView and one as the rightView's subview where I change the subview's position, if possible.

推荐答案

右侧叠加视图被放置在接收器的 rightViewRectForBounds ：方法返回的矩形中。

The right overlay view is placed in the rectangle returned by the rightViewRectForBounds: method of the receiver.

所以我建议你继承 UITextField 并覆盖此方法，如下所示：

So I suggest you subclass UITextField and override this method, something like this:

@interface CustomTextField: UITextField

@end

@implementation CustomTextField

// override rightViewRectForBounds method:
- (CGRect)rightViewRectForBounds:(CGRect)bounds{
    CGRect rightBounds = CGRectMake(bounds.origin.x + 10, 0, 30, 44);
    return rightBounds ;
}
