UISearchBar 文本字段中的自定义清除按钮 [英] Custom clear button in UISearchBar text field
本文介绍了UISearchBar 文本字段中的自定义清除按钮的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧!
问题描述
我试过了:
UITextField *searchtextfield = [searchBar.subviews objectAtIndex:1];
UIButton *cButton = [UIButton buttonWithType:UIButtonTypeCustom];
cButton.frame = CGRectMake(0, 0, 20 , 20);
cButton.backgroundColor = [UIColor clearColor];
[cButton setImage:[UIImage imageNamed:@"x-button"] forState:UIControlStateNormal];//your button image.
cButton.contentMode = UIViewContentModeScaleToFill;
[cButton addTarget:self action:@selector(xButtonPressed) forControlEvents:UIControlEventTouchUpInside];//This is the custom event
[searchtextfield setRightView:cButton];
[searchtextfield setRightViewMode:UITextFieldViewModeWhileEditing];
但是效果不是很好...它显示自定义按钮,但是当您键入内容时,旧按钮又回来了...
But it doesn't work very well... It displays custom button, but when you type something, the old one get's back...
我该怎么做?
推荐答案
如果你想在 UISearchBar 中设置自定义清除按钮,试试这个:
If you want to set a custom clear button in a UISearchBar try this:
[[UISearchBar appearance] setImage:[UIImage imageNamed:@"MyClearButton.png"] forSearchBarIcon:UISearchBarIconClear state:UIControlStateNormal];
不要忘记为 UIControlStateHighlighted
[[UISearchBar appearance] setImage:[UIImage imageNamed:@"HighlightedClearButton.png"] forSearchBarIcon:UISearchBarIconClear state:UIControlStateHighlighted];
