若是想調用某個類的某個方法能夠寫成這樣,這個方法來自NSObject類

performSelector:
performSelector:withObject:
performSelector:withObject:withObject:

實際調用

[self performSelector:@selector(displayViews) withObject:nil afterDelay:1.0f];

 有三個方法分別是

//父視圖
[self.view superview]
//全部子視圖
 [self.view subviews]
//自身的window
 self.view.window

循環一個視圖下面全部視圖的方法

NSArray *allSubviews(UIView *aView)
{
    NSArray *results = [aView subviews];
for (UIView *eachView in [aView subviews])
    {
        NSArray *riz = allSubviews(eachView);
if (riz) {
            results = [results arrayByAddingObjectsFromArray:riz];
        }
    }
return results;
}

循環返回一個APPLICATION裏面全部的VIEW

// Return all views throughout the application
NSArray *allApplicationViews()
{
    NSArray *results = [[UIApplication sharedApplication] windows];
for (UIWindow *window in [[UIApplication sharedApplication] windows])
    {
        NSArray *riz = allSubviews(window);
if (riz) results = [results arrayByAddingObjectsFromArray: riz];
    }
return results;
}

找出全部的父視圖

// Return an array of parent views from the window down to the view
NSArray *pathToView(UIView *aView)
{
    NSMutableArray *array = [NSMutableArray arrayWithObject:aView];
    UIView *view = aView;
    UIWindow *window = aView.window;
while (view != window)
    {
        view = [view superview];
        [array insertObject:view atIndex:0];
    }
return array;
}

UIView提供了大量管理視圖的方法

//加一個視圖到一個視圖裏面
addSubview:
//將一個視圖移到前面
bringSubviewToFront:
//將一個視圖推送到背後
sendSubviewToBack:
//把視圖移除
removeFromSuperview
//插入視圖 並指定索引
insertSubview:atIndex:
//插入視圖在某個視圖之上
insertSubview:aboveSubview:
//插入視圖在某個視圖之下
insertSubview:belowSubview:
//交換兩個位置索引的視圖
exchangeSubviewAtIndex:withSubviewAtIndex:

視圖回調

//當加入視圖完成後調用
(void)didAddSubview:(UIView *)subview
//當視圖移動完成後調用
(void)didMoveToSuperview
//當視圖移動到新的WINDOW後調用
(void)didMoveToWindow
//在刪除視圖以後調用
(void)willRemoveSubview:(UIView *)subview
//當移動視圖以前調用
(void)didMoveToSuperview:(UIView *)subview
//當視圖移動到WINDOW以前調用
(void)didMoveToWindow

給UIView設置標記和檢索視圖

myview.tag = 1001;
[self.view viewWithTag:1001];
(UILable *)[self.view.window viewWithTag:1001];

視圖的幾何特徵

//框架
struct CGPoint {
  CGFloat x;
  CGFloat y;
};
typedefstruct CGPoint CGPoint;

/* Sizes. */

struct CGSize {
  CGFloat width;
  CGFloat height;
};
typedefstruct CGSize CGSize;

struct CGRect {
  CGPoint origin;
  CGSize size;
};
typedefstruct CGRect CGRect;



CGRect rect = CGRectMake(0,0,320,480);
UIView *view = [[UIView allow]initWithFrame:rect];

//將String轉成CGPoint 如 @」{3.0,2.5}」    {x,y}
CGPoint CGPointFromString (
   NSString *string
);

//將String轉成CGRect  @」{{3,2},{4,5}}」  {{x,y},{w, h}}
CGRect CGRectFromString (
   NSString *string
);

//將String轉成CGSize @」{3.0,2.5}」 {w, h}
CGSize CGSizeFromString (
   NSString *string
);

//CGPoint轉成NSString
NSString * NSStringFromCGPoint (
   CGPoint point
);

//CGRect轉成NSString
NSString * NSStringFromCGRect (
   CGRect rect
);

//CGSize轉成NSString
NSString * NSStringFromCGSize (
   CGSize size
);

//對一個CGRect進行修改 以這個的中心來修改 正數表示更小(縮小) 負數表示更大(放大)
CGRect CGRectInset (
   CGRect rect,
   CGFloat dx,
   CGFloat dy
);

//判斷兩個矩形是否相交
bool CGRectIntersectsRect (
   CGRect rect1,
   CGRect rect2
);

//初始爲0的
const CGPoint CGPointZero;
const CGRect CGRectZero;
const CGSize CGSizeZero;

//建立CGPoint
CGPoint CGPointMake (
   CGFloat x,
   CGFloat y
);
//建立CGRect
CGRect CGRectMake (
   CGFloat x,
   CGFloat y,
   CGFloat width,
   CGFloat height
);
//建立CGSize
CGSize CGSizeMake (
   CGFloat width,
   CGFloat height
);

仿射變換

CGAffineTransform form = CGAffineTransformMakeRotation(PI);
myview.transform = form;

如想復原

myview.transform = CGAffineTransformIdentity;

直接設置視圖的中心

myview.center = CGPointMake(100,200);

中心

CGRectGetMinX
CGRectGetMinY
//X的中間值
CGRectGetMidX
//Y的中間值
CGRectGetMidY
CGRectGetMaxX
CGRectGetMaxY

 定時器

NSTime *timer = [NSTimer scheduledTimerWithTimeInterval:0.1f target:self selector:@selector(move:) userInfo:nil repeats:YES];

 定義視圖邊界

typedefstruct UIEdgeInsets {
    CGFloat top, left, bottom, right;  // specify amount to inset (positive) for each of the edges. values can be negative to 'outset'
} UIEdgeInsets;
//eg
UIEdgeInsets insets = UIEdgeInsetsMake(5, 5, 5, 5);
CGRect innerRect = UIEdgeInsetsInsetRect([aView bounds], insets);
CGRect subRect = CGRectInset(innerRect, self.frame.size.width / 2.0f, self.frame.size.height / 2.0f);

仿射變換補充

//建立CGAffineTransform

//angle 在0-2*PI之間比較好  旋轉
CGAffineTransform transform = CGAffineTransformMakeRotation(angle);
//縮放
CGAffineTransform transform = CGAffineTransformMakeScale(0.5f,0.5f);
//改變位置的
CGAffineTransform transform = CGAffineTransformMakeTranslation(50,60);

//修改CGAffineTransform
//修改 縮放
CGAffineTransform scaled = CGAffineTransformScale(transform, degree, degree);
//修改 位置
CGAffineTransform transform = CGAffineTransformTranslate(
   CGAffineTransform t,
   CGFloat tx,
   CGFloat ty
);

//修改角度
CGAffineTransform transform = CGAffineTransformRotate (
   CGAffineTransform t,
   CGFloat angle
);
//最後設置到VIEW
 [self.view setTransform:scaled];

創建UIView動畫塊

  //首先創建CGContextRef

CGContextRef context = UIGraphicsGetCurrentContext();
//標記動畫開始
[UIView beginAnimations:nil context:context];
//定義動畫加速或減速的方式
[UIView setAnimationCurve:UIViewAnimationCurveEaseInOut];
//定義動畫的時長 1秒
[UIView setAnimationDuration:1.0];
//中間處理 位置變化，大小變化，旋轉，等等的
[[self.view viewWithTag:999] setAlpha:1.0f];
//標誌動畫塊結束
[UIView commitAnimations];
//還能夠設置回調
[UIView setAnimationDelegate:self];
//設置回調調用的方法
[UIView setAnimationDidStopSelector:@selector(animationFinished:)];

 視圖翻轉

UIView *whiteBackdrop = [self.view viewWithTag:100];
// Choose left or right flip 選擇左或右翻轉
if ([(UISegmentedControl *)self.navigationItem.titleView selectedSegmentIndex]){
[UIView setAnimationTransition: UIViewAnimationTransitionFlipFromLeft forView:whiteBackdrop cache:YES];
}else{
[UIView setAnimationTransition: UIViewAnimationTransitionFlipFromRight forView:whiteBackdrop cache:YES];
}
    NSInteger purple = [[whiteBackdrop subviews] indexOfObject:[whiteBackdrop viewWithTag:999]];
    NSInteger maroon = [[whiteBackdrop subviews] indexOfObject:[whiteBackdrop viewWithTag:998]];
//交換視圖
    [whiteBackdrop exchangeSubviewAtIndex:purple withSubviewAtIndex:maroon];

//還有上翻和下翻兩種 以下
typedefenum {
//沒有任何效果
    UIViewAnimationTransitionNone,
    UIViewAnimationTransitionFlipFromLeft,
    UIViewAnimationTransitionFlipFromRight,
    UIViewAnimationTransitionCurlUp,
    UIViewAnimationTransitionCurlDown,
} UIViewAnimationTransition;

 使用QuartzCore作動畫

//建立CATransition
CATransition *animation = [CATransition animation];
//設置代理
animation.delegate = self;
//設置動畫過渡的時間
animation.duration = 4.0f;
//定義動畫加速或減速的方式
animation.timingFunction = UIViewAnimationCurveEaseInOut;
//animation.type 表示設置過渡的種類 如 Fade,MoveIn,Push,Reveal
switch ([(UISegmentedControl *)self.navigationItem.titleView selectedSegmentIndex]) {
case 0:
            animation.type = kCATransitionFade;
break;
case 1:
            animation.type = kCATransitionMoveIn;
break;
case 2:
            animation.type = kCATransitionPush;
break;
case 3:
            animation.type = kCATransitionReveal;
default:
break;
    }
//設置漸變的方向，上下左右
if (isLeft)
        animation.subtype = kCATransitionFromRight;
else
        animation.subtype = kCATransitionFromLeft;

// Perform the animation
    UIView *whitebg = [self.view viewWithTag:10];
    NSInteger purple = [[whitebg subviews] indexOfObject:[whitebg viewWithTag:99]];
    NSInteger white = [[whitebg subviews] indexOfObject:[whitebg viewWithTag:100]];
    [whitebg exchangeSubviewAtIndex:purple withSubviewAtIndex:white];
    [[whitebg layer] addAnimation:animation forKey:@"animation"];

animation.type還能夠用如下的賦值

switch (theButton.tag) {
case 0:
            animation.type = @"cube";
break;
case 1:
            animation.type = @"suckEffect";
break;
case 2:
            animation.type = @"oglFlip";
break;
case 3:
            animation.type = @"rippleEffect";
break;
case 4:
            animation.type = @"pageCurl";
break;
case 5:
            animation.type = @"pageUnCurl";
break;
case 6:
            animation.type = @"cameraIrisHollowOpen ";
break;
case 7:
            animation.type = @"cameraIrisHollowClose ";
break;
default:
break;
    }

休眠一下

[NSThread sleepUntilDate:[NSDate dateWithTimeIntervalSinceNow:1.0f]];

一個簡單的經過圖片作的動畫

// Load butterfly p_w_picpaths
NSMutableArray *bflies = [NSMutableArray array];
for (int i = 1; i <= 17; i++){
    [bflies addObject:[UIImage p_w_picpathWithContentsOfFile:[[NSBundle mainBundle] pathForResource:[NSString stringWithFormat:@"bf_%d", i] ofType:@"png"]]];
}
UIImageView *butterflyView = [[UIImageView alloc] initWithFrame:CGRectMake(40.0f, 300.0f, 60.0f, 60.0f)];
butterflyView.tag = 300;
//設置動畫的圖片
butterflyView.animationImages = bflies;
//設置時間
butterflyView.animationDuration = 0.75f;
[self.view addSubview:butterflyView];
//開始動畫
[butterflyView startAnimating];
[butterflyView release];
