UISearchBar自定義
方式一.

//去掉陰影框線
self.searchBar.backgroundImage = [UIImage new];
//文字和搜索圖標(biāo) 在左邊
- (void)setHasCentredPlaceholder:(UISearchBar *)searchBar
{
SEL centerSelector = NSSelectorFromString([NSString stringWithFormat:@"%@%@", @"setCenter", @"Placeholder:"]);
if ([self.searchBar respondsToSelector:centerSelector])
{
NSMethodSignature *signature = [[UISearchBar class] instanceMethodSignatureForSelector:centerSelector];
NSInvocation *invocation = [NSInvocation invocationWithMethodSignature:signature];
[invocation setTarget:self.searchBar];
[invocation setSelector:centerSelector];
[invocation setArgument:&searchBar atIndex:2];
[invocation invoke];
}
}
xib:searcher的barTint和view的Tint的顏色設(shè)置white

//修改背景
//顏色——>Image
- (UIImage *)createImageWithColor: (UIColor *) color{
CGRect rect=CGRectMake(0.0f, 0.0f, 1.0f, 1.0f);
UIGraphicsBeginImageContext(rect.size);
CGContextRef context = UIGraphicsGetCurrentContext();
CGContextSetFillColorWithColor(context, [color CGColor]);
CGContextFillRect(context, rect);
UIImage *theImage = UIGraphicsGetImageFromCurrentImageContext();
UIGraphicsEndImageContext();
return theImage;
}
UISearchBar *searchBar = [[UISearchBar alloc] initWithFrame:CGRectMake(0, 0, self.view.frame.size.width, 44)];
//修改搜索框的顏色
searchBar.autocorrectionType = UITextAutocorrectionTypeNo;
searchBar.backgroundColor= [UIImage createImageWithColor:[UIColorclearColor]];;
NSArray *arr = searchBar.subviews;
for (UIView *subView in arr)
{
NSArray *arr2 = subView.subviews;
for (UIView *subView2 in arr2)
{
if ([subView2 isKindOfClass:NSClassFromString(@"UISearchBarBackground")])
{
[subView2 removeFromSuperview];
break;
}
}
}
UIView *view = [[UIView alloc] initWithFrame:searchBar.frame];
view.backgroundColor = [UIColor clearColor];
[searchBar insertSubview:view atIndex:0];
