Ios 在视图上显示自定义线

嗨，我想在视图中显示一条线，就像给定的图像一样

但当我这样做的时候，我会看到整个线路

我的代码-

UIView *lineView = [[UIView alloc] initWithFrame:CGRectMake(2,30, _MovetoSearch.frame.size.width, 1)];
lineView.backgroundColor = [UIColor whiteColor];
[_MovetoSearch addSubview:lineView];

如何制作上图所示的线条？

当您设置子图幅时，始终使用父图幅进行设置，因此，如果将来您可以更改父图幅，则无需更改子图幅，它将根据父图自动更改，如我所述

UIView *lineView = [[UIView alloc] initWithFrame:CGRectMake(_MovetoSearch.frame.origin.x+2,_MovetoSearch.frame.size.height-5, _MovetoSearch.frame.size.width-30, 1)];
    lineView.backgroundColor = [UIColor whiteColor];
    [_MovetoSearch addSubview:lineView];

我假设您的

searchBtn

也有类似的代码

UIButton *searchBtn = [UIButton buttonWithType:UIButtonTypeCustom];
[searchBtn setFrame:CGRectMake(_MovetoSearch.frame.size.width-32, 0, 32, 32)];    
[searchBtn setImage:[UIImage imageNamed:@"search.png"] forState:UIControlStateNormal];
[searchBtn setImage:[UIImage imageNamed:@"search.png"] forState:UIControlStateHighlighted];
[searchBtn addTarget:self action:@selector(searchBtnPressed) forControlEvents:UIControlEventTouchUpInside];

对于您的

UITextField

应该是

CGFloat fieldHeight = searchBtn.frame.size.height-2;
CGFloat fieldWidth = _MovetoSearch.frame.size.width - (searchBtn.frame.size.width + 4);

UITextField *textfield = [[UITextField alloc] initWithFrame:CGRectMake(2, 0, fieldWidth, fieldHeight)];
[textfield setBackgroundColor:[UIColor clearColor]];
[textfield setBorderStyle:UITextBorderStyleNone];
[textfield setNeedsDisplay];
[_MovetoSearch addSubview:textfield];

用于线视图

CGFloat fieldHeight = searchBtn.frame.size.height-2;
CGFloat fieldWidth = _MovetoSearch.frame.size.width - (searchBtn.frame.size.width + 4);

UIView *lineView = [[UIView alloc] initWithFrame:CGRectMake(2, fieldHeight+1, fieldWidth, 1)];
lineView.backgroundColor = [UIColor whiteColor];

[_MovetoSearch addSubview:lineView];

希望它对您有用

我建议您使用layer来完成这样的任务，不要过度使用UIView

CALayer * lineLayer = [CALayer alloc]init];
[lineLayer setFrame:CGRectMake(x,y,width,1)];
[lineLayer setBackgroundColor:[UIColor whiteColor].CGColor];
[self.view.layer addSublayer:lineLayer];

没有得到？你面临的问题是什么？“想在视图中显示一条线”，哪种视图？@Neon Samuel如何制作上述图像的线条什么是

\u MovetoSearch

，您是否在

\u MovetoSearch

视图中包含搜索图标图像？@Sujay move ToSearch是uiviewhi的实例您能告诉我您的答案如何适合我的问题吗？您说的是不同的东西文本字段行和按钮，但我想要一行吗解开按钮或uiview并在图像中显示。如果你是对的，我怎么能使用你的代码呢？这只是一个设计，我只是想让ed通过action top其他视图。我想像上面一样设计
