一：
- (void)viewDidLoad
{
[super viewDidLoad];//1UIImage* clearImg = [CDViewController imageWithColor:[UIColor clearColor] andHeight:32.0f];//2[_searchBar setBackgroundImage:clearImg];//3[_searchBar setSearchFieldBackgroundImage:clearImg forState:UIControlStateNormal];//4[_searchBar setBackgroundColor:[UIColor clearColor]];
}+ (UIImage*) imageWithColor:(UIColor*)color andHeight:(CGFloat)height
{
CGRect rect= CGRectMake(0.0f,0.0f,1.0f, height);
UIGraphicsBeginImageContext(rect.size);
CGContextRef context=UIGraphicsGetCurrentContext();
CGContextSetFillColorWithColor(context, [color CGColor]);
CGContextFillRect(context, rect);
UIImage*image =UIGraphicsGetImageFromCurrentImageContext();
UIGraphicsEndImageContext();returnimage;
}
二：直接调，就完事了！
- (void)viewDidLoad
{
[super viewDidLoad];//1UIImage* clearImg = [CDViewController imageWithColor:[UIColor clearColor] andHeight:32.0f];
//2[_searchBar setBackgroundImage:clearImg];
//3[_searchBar setSearchFieldBackgroundImage:clearImg forState:UIControlStateNormal];
//4[_searchBar setBackgroundColor:[UIColor clearColor]];
}
+(UISearchBar*)createSearchBarWithFrame:(CGRect)frame andTarget:(id) target andWithPlaceHolderTitle:(NSString *)title{
UISearchBar * searchBar = [[UISearchBar alloc]initWithFrame:frame];
searchBar.placeholder= title;
searchBar.delegate = target;
[searchBar setContentMode:UIViewContentModeBottomLeft];
searchBar.tintColor=LTColor(0, 122, 255, 1.0);
searchBar.backgroundColor = [UIColor clearColor];
for (UIView *view in searchBar.subviews) {
// for before iOS7.0
if ([view isKindOfClass:NSClassFromString(@"UISearchBarBackground")]) {
[view removeFromSuperview];
break;
}
// for later iOS7.0(include)
if ([view isKindOfClass:NSClassFromString(@"UIView")] && view.subviews.count > 0) {
[[view.subviews objectAtIndex:0] removeFromSuperview];
break;
}
}
return searchBar;
}
