searchbar下的搜索图标及textfiled样式修改

自定义searchbar,重写layoutSubviews就行了，只是ios7以下与IOS7获取UITextField的方法不同

-(void)layoutSubviews

{

UITextField *searchField;

searchField = Nil;

if (!IsiOS7()) {

NSUInteger nums = [self.subviews
count];

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

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

searchField = [self.subviews
objectAtIndex:i];

[searchField retain];

}

}

}else{

searchField = [self
valueForKey:@"_searchField"];

[searchField initWithFrame:CGRectMake(0, 0,IsPad()?768-60:self.frame.size.width, 44)];

searchField.textAlignment = NSTextAlignmentLeft;

}

if(!(searchField == nil)) {

[searchField setBorderStyle:UITextBorderStyleRoundedRect];

//自定义放大镜图片

UIImage *image = [UIImage
imageNamed: @"search_ico2"];

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

if (!IsiOS7()) {

iView.frame = CGRectMake(10, 4, 24, 24);

searchField.leftView.hidden = YES;

[searchField addSubview:iView];

}

else

{

iView.frame = CGRectMake(0, 0, 26, 26);

searchField.leftView = iView;

}

//修改文本框背景色

searchField.backgroundColor = VUIColorFromRGB(0xe9d9ca);

searchField.textColor = VUIColorFromRGB(0x000000);

//改变placeholder字体颜色

[searchField setValue:VUIColorFromRGB(0xcbbcab) forKeyPath:@"_placeholderLabel.textColor"];

[iView release];

}

[super
layoutSubviews];

}
