自定义UISearchBar的背景图

 

可以重写UISearchBar，然后调用layoutSubviews这个方法。

- (void)layoutSubviews {     UITextField *searchField;     NSUInteger numViews = [self.subviews count];     for(int i = 0; i < numViews; i++) {         if([[self.subviews objectAtIndex:i] isKindOfClass:[UITextField class]]) {             searchField = [self.subviews objectAtIndex:i];         }     }     if(!(searchField == nil)) {         searchField.textColor = [UIColor whiteColor];         [searchField.leftView setHidden:YES];         [searchField setBackground: [UIImage imageNamed:@"SearchBarBackground.png"] ];         [searchField setBorderStyle:UITextBorderStyleNone];     }           [super layoutSubviews]; }
