IOS開發之UISearchBar自訂外觀

               MySearchBar.h如下：

@interface MySearchBar : UISearchBar

- (void)layoutSubviews;

@end

MySearchBar.m如下：

#import "MySearchBar.h"

@implementation MySearchBar

- (void)layoutSubviews {

UITextField *searchField;

NSUInteger numViews = [self.subviews
count];

for(int i =
0; i < numViews; i++) {

if([[self.subviews
objectAtIndex:i] isKindOfClass:[UITextField
class]]) { //conform?

searchField = [self.subviews
objectAtIndex:i];

}

}

if(!(searchField ==
nil)) {

searchField.textColor = [UIColor
redColor];

[searchField
setBorderStyle:UITextBorderStyleRoundedRect];

UIImage *image = [UIImage
imageNamed: @"出發位置.png"];

UIImageView *iView = [[UIImageView
alloc] initWithImage:image];

searchField.leftView = iView;

}

[super
layoutSubviews];

}

@end

應用：

MySearchBar *searchBar = [MySearchBar alloc]  initWithRct:CGRectMark(10, 10 ,100,30)];

   searchBar.backgroundColor = [UIColor
clearColor];   //修改搜尋方塊背景

    searchBar.showsScopeBar =
NO;  

    

    [[searchBar.subviews
objectAtIndex:0]removeFromSuperview]; 
//去掉搜尋方塊背景

    for (UIView *subview
in searchBar.subviews) {  

        if ([subview
isKindOfClass:NSClassFromString(@"UISearchBarBackground")]) {  

            [subview removeFromSuperview];  

            break;  

        }  

    } 

    

//    UIView *baView = [[UIView alloc] init];

//    baView.backgroundColor = [UIColor clearColor];

//    

//    [searchBar insertSubview:baView atIndex:1];
