　UITextField *txfSearchField = [looksearchbar valueForKey:@"_searchField"];
[txfSearchField setBackgroundColor:[UIColor whiteColor]];
[txfSearchField setLeftViewMode:UITextFieldViewModeNever];
[txfSearchField setRightViewMode:UITextFieldViewModeNever];
[txfSearchField setBackground:[UIImage imageNamed:@"searchbar_bgImg.png"]];
[txfSearchField setBorderStyle:UITextBorderStyleNone];
//txfSearchField.layer.borderWidth = 8.0f;

txfSearchField.layer.borderColor = [UIColor clearColor].CGColor;
txfSearchField.clearButtonMode=UITextFieldViewModeNever;
