延展： 狀態欄 高度 24， 導航欄 高度 44， 工具欄 高度 49.

控件 預留 Padding/ UIEdgeInsets.

有意思

UIBarButtonItem * fixedButton = [[UIBarButtonItem alloc ] initWithBarButtonSystemItem: UIBarButtonSystemItemFixedSpace target: tarObject action: nil ];
    fixedButton.width = kScreenWidth/7;

?

tempToolBar.items = @[cancelButton, fixedButton, confirmButton] ;

沒有 預料到 左右 預留的 間距， 應該是 UITextField 的 inputAccsoryView 造成的。

沒想到 兩個圖片 中間 還有間距， 什么鬼。

+ (UIToolbar *)createAccessoryToolbarWithExeSel: (SEL ) exeSel withTarget: (id) tarObject withCancelSel: (SEL) cancelSel withExeBtnTag: (NSInteger ) exeTag
{
    CGFloat theButtonWidth = (kScreenWidth-15*2 -10)/2;
    UIToolbar * tempToolBar = [[UIToolbar alloc ] initWithFrame: CGRectMake(0, 0, kScreenWidth,  50) ];
    tempToolBar.barStyle =  UIBarStyleDefault;
    tempToolBar.translucent = YES;
    tempToolBar.backgroundColor = [ZheUtil colorWithHexString: @"#53C168" ];
    
    
    tempToolBar.userInteractionEnabled = YES;
    
   
    UIButton * confirmBtn = [UIButton buttonWithType: UIButtonTypeCustom ];
    confirmBtn.frame = CGRectMake( 0 , 0, theButtonWidth, 50 ) ;
    [confirmBtn setTitle: @"確定" forState: UIControlStateNormal ];
    confirmBtn.titleLabel.font = [UIFont systemFontOfSize: 15 ];
    [confirmBtn setTitleColor: [UIColor whiteColor] forState: UIControlStateNormal ];
    [confirmBtn addTarget: tarObject action: exeSel forControlEvents: UIControlEventTouchUpInside ];
    confirmBtn.backgroundColor = [UIColor blueColor ];
    confirmBtn.titleLabel.textAlignment = NSTextAlignmentCenter;
    confirmBtn.tag = exeTag;
    
    
    UIBarButtonItem * confirmButton = [[UIBarButtonItem alloc ] initWithCustomView: confirmBtn ];
    
    
    
    UIButton * cancelBtn = [UIButton buttonWithType: UIButtonTypeCustom ];
    cancelBtn.frame = CGRectMake( 0 , 0, theButtonWidth, 50 ) ;
    cancelBtn.titleLabel.textAlignment = NSTextAlignmentCenter;
    [cancelBtn addTarget: tarObject action: cancelSel forControlEvents: UIControlEventTouchUpInside ];
    [cancelBtn setTitle: @"取消" forState: UIControlStateNormal ];
    cancelBtn.titleLabel.font = [UIFont systemFontOfSize: 15 ];
    [cancelBtn setTitleColor: [UIColor whiteColor] forState: UIControlStateNormal ];
    cancelBtn.backgroundColor = [UIColor magentaColor ];
    UIBarButtonItem * cancelButton = [[UIBarButtonItem alloc ] initWithCustomView: cancelBtn ];
    
    [tempToolBar setItems: @[cancelButton, confirmButton] animated: YES ];
    
    return tempToolBar;
}

OK 了， 自己算出來的。
