在众多移动应⽤用中,能看到各式各样的表格数据 。
在iOS中,要实现表格,数据,图片添加,按钮点击等方法的展示,最常用的做法就是使用UI中的基本控件来完成 。
首先在AppDelegate.m里初始化window:
#import "AppDelegate.h"
@interface AppDelegate ()
@end
@implementation AppDelegate
- (void)dealloc
{
[_window release]; //释放window
[super dealloc];
}
#pragma make -- app启动完成走这个方法
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
#//初始化Window对象
self.window = [[UIWindow alloc] initWithFrame:[UIScreen mainScreen].bounds];
#//设置颜色:
self.window.backgroundColor = [UIColor whiteColor];
#//让window可见:
[self.window makeKeyAndVisible];
#//为window创建根视图控制器:
UIViewController *vc = [[UIViewController alloc] init];
#//将vc设置为window的根视图控制器:
self.window.rootViewController = vc;
UILable : (标签控件的常用属性)
//初始化标签控件:
UILabel *label = [[UILabel alloc]
initWithFrame:CGRectMake(100, 200, 175, 100)];
//设置背景颜色:
label.backgroundColor = [UIColor grayColor];
//设置label要显示的文字:
label.text = @"Hello student!";
//设置文字对齐方式:(左中右三种 0.1.2)
label.textAlignment = NSTextAlignmentCenter; //给1也行
//设置字体颜色:
label.textColor = [UIColor yellowColor];
//设置字体和大小:
// label.font = [UIFont fontWithName:@"Zapfino" size:20];
//设置显示的行数(换行):(0表示自动去换行)
label.numberOfLines = 0;
//设置断行模式:
label.lineBreakMode = NSLineBreakByWordWrapping; //按
字母用Char换Word
UITextField :(文本框的常用属性)
//初始化文本框:
UITextField *textfield = [[UITextField alloc]
initWithFrame:CGRectMake(100, 100, 175, 50)];
//设置提示文字:
textfield.placeholder = @"请输入密码:";
//设置边框样式:
textfield.borderStyle = UITextBorderStyleRoundedRect;
//设置边框宽度和颜色:
textfield.layer.borderWidth = 5.0;
textfield.layer.borderColor = [UIColor blueColor].CGColor
//设置文本颜色:
textfield.textColor = [UIColor redColor];
//设置文本对齐方式:(0.1.2 左 中 右)
textfield.textAlignment = 0;
//设置字体:
textfield.font = [UIFont fontWithName:@"Helvetica-Bold" size:15];
#注意字体的书写一定要标准
//是否允许编辑:
textfield.enabled = YES; //(NO 不可编辑,默认为yes)
//开始输入时清空之前的内容:
textfield.clearsOnBeginEditing = NO; //(NO就清空了,默认为 YES)
//设置密码输入模式(小点):
textfield.secureTextEntry = YES; //no为正常输入
//设置键盘的样式:
// textfield.keyboardType = UIKeyboardTypeDefault;
// 比如只能输入数字textfield.keyboardType = UIKeyboardTypeNumberPad;
//设置键盘右下角按钮内容:
textfield.returnKeyType = UIReturnKeyNext; //有很多种
UIButton :(按钮的常用属性)
//初始化按钮:
UIButton *button = [UIButton buttonWithType:UIButtonTypeCustom];
//设置位子
button.frame = CGRectMake(100, 100, 175, 64);
//设置按钮文字:
[button setTitle:@"我是按钮" forState:UIControlStateNormal];
//设置边框:
// button.layer.borderWidth = 2.0;
//设置边框颜色:
// button.layer.borderColor= [UIColor greenColor].CGColor;
//设置背景颜色
// button.backgroundColor = [UIColor blackColor];
//设置圆角:
// button.layer.cornerRadius = 10;
//设置背景图:
// [button setBackgroundImage:[UIImage
imageNamed:@"1.jpg"] forState:UIControlStateNormal];
//设置前景图
// [button setImage:[UIImage imageNamed:@"666.jpg"]
forState:UIControlStateNormal];
// UIImage *frontImage = [button
imageForState:UIControlStateNormal];
// NSLog(@"%@", frontImage);
// //设置按钮字体颜色:
[button setTitleColor:[UIColor redColor]
forState:UIControlStateNormal];
//修改字体大小以及字体:
//修改字体大小以及字体:
button.titleLabel.font = [UIFont fontWithName:@"Zapfino"
size:20];
//获取字体颜色:
UIColor *wordColor = [button
titleColorForState:UIControlStateNormal];
NSLog(@"%@", wordColor);
//为按钮button添加点击事件:
[button addTarget:self action:@selector(didClickedDogButton:) forControlEvents:UIControlEventTouchUpInside];
//为按钮移除点击事件
[button removeTarget:self action:@selector(didClickedDogButton:) forControlEvents:UIControlEventTouchUpInside];
//最后将按钮添加到window上
[view addSubview:button];
#注意:按钮是系统自动释放 不用再release ,否则将会过度释放
UIImageView :(图片显示控件的常用属性)
//创建UIImageView对象:
UIImageView *imageView = [[UIImageView
alloc]initWithFrame:self.window.frame];
//设置颜色:
// imageView.backgroundColor = [UIColor orangeColor];
//为imageView设置图片:
// imageView.image = [UIImage imageNamed:@"1.jpg"];
更多图片的属性和方法以后会介绍,这里简单为大家做个植物大战僵尸中每个图片及方法的实现,希望能帮助大家理解:
# 首先我们需要将已有的图片文件拖到自己的工程里:比如下面
BackGround.png
//1).设置整体背景:
imageView.image = [UIImage
imageNamed:@"BackGround"];
#这里以向日癸为例,僵尸,瓜等同理
(因为没找到符合简书规格的图片,暂不上传 sorry)
//2).循环创建动画素材(UIImage对象)
NSMutableArray *flowerArray = [NSMutableArray array];
for (NSInteger i = 1; i <= 18; i++) {
//拼接每个图片的名字:
NSString *name = [NSString stringWithFormat:@"flower%ld.tiff", i];
UIImage *image = [UIImage imageNamed:name];
[flowerArray addObject:image];
}
//3).创建单独的UIImageView对象
UIImageView *flowerIamgeView = [[UIImageView alloc]initWithFrame:CGRectMake(50, 80, 73, 74)];
[imageView addSubview:flowerIamgeView];
[flowerIamgeView release];
//4).将数组赋值给imageView
flowerIamgeView.animationImages = flowerArray;//********
//5).设置播放图片的时间间隔(两张图片之间播放的时间差):
flowerIamgeView.animationDuration = 1.0f;
//6).设置一下重复次数:
// flowerIamgeView.animationRepeatCount = 5;
#当重复次数为0时就一直保持图片动态播放
//7).开始动画
[flowerIamgeView startAnimating];
//花动起来:
[UIView animateWithDuration:10 animations:^{
flowerIamgeView.frame = CGRectMake(200, 400, 146, 148);
}];
