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：
