开发小技巧：如何设置导航栏右侧的图标位置LBQ_DS经验分享

前言：开发中常有在导航栏添加图标的需求，可以直接用系统自定义的，但有时候希望图标在自己想要的位置出现，但系统自定义的按钮位置是固定的 所以我参照网上的资料 再通过自己的实践总结得出下面的两个方法：

刚开始没设置位置的时候，按钮和右边的距离很大：

方法一：如下代码所示

参考文章：http://www.jianshu.com/p/5f3eae0c0bd9

// 右侧

UIButton *button = [UIButton buttonWithType:UIButtonTypeCustom];

//修改按钮向右移动10pt

[button setFrame:CGRectMake(10.0, 1.0, 60, 25)];

[button setTitle:@"私信HR" forState:UIControlStateNormal];

[button setBackgroundImage:[UIImage imageNamed:@"com_sendToHr_Btn"] forState:UIControlStateNormal];

[button setTitleColor:kBlackColor forState:UIControlStateNormal];

button.titleLabel.font = KFontWithSize(12);

[button addTarget:self action:@selector(sendPrivateLetter) forControlEvents:UIControlEventTouchUpInside];

//把button添加到view中

UIView *view = [[UIView alloc] initWithFrame:CGRectMake(0.0, 0.0, 60.0, 25.0)];

  view.backgroundColor = [UIColor redColor];

[view addSubview:button];

self.navigationItem.rightBarButtonItem = [[UIBarButtonItem alloc] initWithCustomView:view];

把红色去掉之后：

方法二：代码如下所示：

// 右侧

UIButton *button = [UIButton buttonWithType:UIButtonTypeCustom];

//修改按钮向右移动10pt

[button setFrame:CGRectMake(0, 0, 60, 25)];

[button setTitle:@"私信HR" forState:UIControlStateNormal];

[button setBackgroundImage:[UIImage imageNamed:@"com_sendToHr_Btn"] forState:UIControlStateNormal];

[button setTitleColor:kBlackColor forState:UIControlStateNormal];

button.titleLabel.font = KFontWithSize(12);

[button addTarget:self action:@selector(sendPrivateLetter) forControlEvents:UIControlEventTouchUpInside];

/******/

UIBarButtonItem *rightItem = [[UIBarButtonItem alloc] initWithCustomView:button];

//增加一个UIBarButtonItem.

UIBarButtonItem *nagetiveSpacer = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemFixedSpace target:nil action:nil];

//这个值可以根据自己需要自己调整

nagetiveSpacer.width = -10;

self.navigationItem.rightBarButtonItems = @[nagetiveSpacer, rightItem];

/******/

效果：
