//準備工作

1.刪除Main 2.ARC->MRC(YES->No) 3.刪除文件（ViewConTroller.h/.m） 4.strong->retain(AppDelegate.H)5.重寫dealloc

//第一步：創建window和當前屏幕一樣大[UIScreen mainScreen].bounds

self.window = [UIWindow alloc]initWithFrame:[UIScreen mainScreen].bounds];

//第二步：設置window顏色

self.window.backgroungColor = [UIColor whiteColor];

//第三步：設置window可見

[self.window makeKeyAndVisible];

//第四步：xcode7崩潰解決

self.window.rootViewController = [UIViewController alloc]init];

[UIViewController alloc]init];

//第五步：內存管理

[_window release];

//1.創建試圖設置frame

UIView *firstView = [UIView alloc]initWithFrame:CGRectMake(0,0,100,100)];

//2.設置屬性

firstView.bavkgroundColor = [UIColor redColor];

//3.添加到父試圖（window）顯示

[self.window addSubview：firstView];

//創建blueView

UIView *blueView = [UIView alloc] initWithFrame:CGRectMake(0,0,200,200)];

blueView.backgroundColor = [UIColor blueColor];

[self.window addSubview：blueView];

[blueView release];

//中心顯示

//數值設置（絕對坐標）

blueView.center = CGPointMake(375/2,667/2);

//通過其他控制件位置設置（相對坐標）

blueView.center = self.window.center;

//改變frame

blueView.frame = CGRectMake(200,100,100,200);

//居中

self.window addSubView:blueView;

//顯示隱藏

aView.hidden = NO;

//透明度alpha(0-1的浮點數)

aView.alpha = 1;

//標記值：tag

aView.tag = 1000;

//改變顏色：通過標記尋找試圖

UIView*tempView = [self.window viewWithTag:1000];

te,pView.backgroundColor = [UIColor purpleColor];

//父視圖（一個父視圖只有一個父試圖）

//子視圖（一個視圖可以有若干個子視圖）

//隨機顏色

cView.backgroundColor = [UIColor colorWithRed:arc4random() % 256 / 255.0 green:arc4random() % 256 / 255.0 blue:arc4random() % 256 / 255.0 alpha:1];

//UILabel

//1.創建+fram

? ?UILabel *label = [[UILabel alloc]initWithFrame:CGRectMake(100, 100, 200, 100)];

? ?//2.屬性設置

? ?label.backgroundColor = [UIColor yellowColor];

? ?//3.添加父視圖

? ?[self.window addSubview:label];

? ?//4.內存管理

? ?[label release];

/******label文字相關屬性*****/

//顯示文字text

//默認左對齊/居中顯示/文本黑色/行數為1/背景透明色

//居中改不了

//文本顏色 textColor

lable.textColor= [UIColor purpleColor];

//文本對齊方式 textAlignment

lable.textAlignment = NSTextAlignmentCenter;

//斷行模式（文本省略方式）lineBreakMode

lable.lineBreakMode = NSLineBreakByTruncatingMiddle;//中間省略

//文本行數 numberOflines

? ?//默認為1 為0時行數不限

? ?label.numberOfLines = 0;

? ?//label自適應 sizeToFit

? ?//如果文本不足一行寬高一起改變

? ?//如果文本超過一行只改變高

? ?//一定要寫在設置text之后如果寫在之前 label的size會置為0

? ?[label sizeToFit];

? ?//字體 font

? ?label.font = [UIFont systemFontOfSize:20];

? ?//陰影 shadow

? ?label.shadowColor = [UIColor blackColor];

? ?//陰影偏移量

? ?label.shadowOffset = CGSizeMake(10, 10);

//鍵盤回收:

//必須用到協議,設置代理人,實現方法;
