1.移除视图的所有子视图

2.自定义视图(UIView)

4.自定义签名视图(可以手写字) 

5.图片拉伸的几种方式，计算文本占用空间大小

6.UILable相关

9.UIScrollView相关

10.UISearchController相关

11.UICollectionView相关

12.单元格右侧样式

13.自定义UISlider样式

14.启动引导页视图

移除视图的所有子视图

[[self.view subviews] makeObjectsPerformSelector:@selector(removeFromSuperview)];

或者 

    NSArray *viewsToRemove = [self.view subviews];
    
    for (UIView *view in viewsToRemove) {
        
        [view removeFromSuperview];
        
    }

自定义视图(UIView)

//FaceView.m文件 

@implementation FaceView 
-(id)initWithFrame:(CGRect)frame{
    self=[super initWithFrame:frame];
    if (self) {
      
    }
    return self;
}

//自己实现drawRect方法重绘 ,也可以不实现该方法，自己定义执行界面处理方法执行
-(void) drawRect:(CGRect)rect{ //省略实现。。。 
     
}
@end

处理悬浮窗口(类似微信视频)，等比缩放  

将要加载的view放在主window上或者根视图控制器上，利用transform将视图等比缩放

下面将一个视图在AppDelegate中处理

  FloatingView *view=[[FloatingView alloc] initWithFrame:CGRectMake(50, 50, 200, 200)];
    //添加拖动手势，使视图达到悬浮窗的拖动效果
    UIPanGestureRecognizer *panGestures=[[UIPanGestureRecognizer alloc] initWithTarget:self action:@selector(handlePanGestures:)];
    [view addGestureRecognizer:panGestures];
    //单击视图手势
    UITapGestureRecognizer *tapGestures=[[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(narrowView:)];
    [view addGestureRecognizer:tapGestures];
    [self.window addSubview:view];

//点击等比缩小视图
-(void)narrowView:(UITapGestureRecognizer *)sender{
    //等比缩放视图
    sender.view.transform=CGAffineTransformScale(sender.view.transform, 0.5, 0.5);
}

//处理视频视图拖动事件
-(void)handlePanGestures:(UIPanGestureRecognizer *)sender{
if(sender.state!=UIGestureRecognizerStateEnded&&sender.state!=UIGestureRecognizerStateFailed) {
         //通过使用 locationInView 这个方法,来获取到手势的坐标
        CGPoint location=[sender locationInView:sender.view.superview];
        sender.view.center=location;
    }
}

图片拉伸的几种方式，计算文本占用空间大小

*ios4提供的方法：

　　- (UIImage *)stretchableImageWithLeftCapWidth:(NSInteger)leftCapWidth topCapHeight:(NSInteger)topCapHeight

　　这个函数是UIImage的一个实例函数，它的功能是创建一个内容可拉伸，而边角不拉伸的图片，需要两个参数，第一个是不拉伸区域距离左边框的宽度，第二个参数是不拉伸区域距离上边框的宽度，其操作本质是对一个像素的复制拉伸，故没有渐变效果，这也是其缺点所在。

　　参数的意义是，如果参数指定10，5。那么，图片左边10个点，上边5个点。不会被拉伸，x坐标为11的点会被横向复制，y坐标为6的点会被纵向复制。注意：只是对一个点像素进行复制到指定的宽度。

*ios5提供的方法:

　　- (UIImage *)resizableImageCapInsets:(UIEdgeInsets)Insets

　　其中Insets这个参数的格式是(top,left,bottom,right)，从上、左、下、右分别在图片上画了一道线，这样就给一个图片指定了一个矩形区域。只有在框里面的部分才会被拉伸，而框外面的部分则保持改变。比如(20,5,10,5)，意思是下图矩形里面的部分可以被拉伸，而其余部分不变。

*ios6提供的方法：

　　- (UIImage *)resizableImageWithCapInsets:(UIEdgeInsets)capInsets resizingMode:(UIImageResizingMode)resizingMode

　　关于Insets参数，与ios5是相同的，不同的是其后增加了一个拉伸的模式，ios6.0的版本提供了

　　UIImageResizingModeTile和 UIImageResizingModeStretch两种模式，从名字就可以看出，是平铺模式和拉伸模式。平铺就是复制你Insets指定的矩形区域块来填充你所指定的图片区域，而拉伸就是通过拉伸你Insets指定的矩形区域块来填充你 所需的图片区域。图片的resize由一个点变成了一个矩形块，这样你的所指定块的渐变效果，也是可以呈现出来的。

示例：

float bgImgViewX=self.frame.size.width-90-messageSize.width;
//背影图片
UIImage *bgImg=[UIImage imageNamed:@"send_bg.png"];
self.bgImgView=[[UIImageView alloc] initWithImage:[bgImg resizableImageWithCapInsets:UIEdgeInsetsMake(10, 10, 10, 15) resizingMode:UIImageResizingModeStretch]];
self.bgImgView.frame = CGRectMake(bgImgViewX, 14.0f, messageSize.width+30.0f, messageSize.height+20.0f);

计算文本要占用的空间大小 

//CGSizeMake(200, 500)是允许最大占范围
CGSize messageSize=[messageText boundingRectWithSize:CGSizeMake(200, 500) options:NSStringDrawingUsesLineFragmentOrigin attributes:@{NSFontAttributeName:[UIFont systemFontOfSize:20.0f]} context:nil].size;

UILable相关

UILable文字增加阴影效果

//文本加阴影

self.messageLable.shadowColor=[UIColor blackColor];

//正数右下角有阴影效果，负数左上角有阴影效果

self.messageLable.shadowOffset=CGSizeMake(0, 1.0);

UIButton相关

设置按钮边框颜色，边框线大小

//设置按钮边框线粗细

[self.twoVideoBtn.layer setBorderWidth:1.0f];

//设置按钮边框颜色

self.twoVideoBtn.layer.borderColor = [[UIColor colorWithRed:193/255.0green:193/255.0 blue:193/255.0 alpha:1] CGColor];

UISegmentedControl分段控件

UISegmentedControl *segmentedControl=[[UISegmentedControl alloc] initWithItems:@[@"One",@"Two",@"Three"]];
//设置默认选中栏，按下标从零开始。
segmentedControl.selectedSegmentIndex=0;
//momentary设置为YES，不显示选择状态
//segmentedControl.momentary=YES;
[segmentedControl addTarget:self action:@selector(changedValue:) forControlEvents:UIControlEventValueChanged];
self.navigationItem.titleView=segmentedControl;

-(void)changedValue:(UISegmentedControl *)sender{
//   int x= sender.selectedSegmentIndex;
}
