NSArray *titleArray=@[@"最新活动",@"我的活动"];
UISegmentedControl *segment =[[UISegmentedControl alloc]initWithItems:titleArray]; segment.frame=CGRectMake(48, 100, 220, 30);
//背景颜色
segment.tintColor=[UIColor orangeColor];
//设置字体大小
[segment setTitleTextAttributes:[NSDictionary dictionaryWithObjectsAndKeys:[UIFont systemFontOfSize:15],NSFontAttributeName, nil] forState:UIControlStateNormal];
//添加点击事件
[segment addTarget:self action:@selector(segmentAction:) forControlEvents:UIControlEventValueChanged];
//设置默认选择项
segment.selectedSegmentIndex=0;
//点击后是否恢复原样
segment.momentary = YES;
//设置某一项宽度
[segmented setWidth:70.0 forSegmentAtIndex:2]; [self.view addSubview:segment];
方法实现
- (void)segmentAction:(UISegmentedControl *)seg{
if (seg.selectedSegmentIndex==0) {
NSLog(@"^o^");
}
else{
NSLog(@"oo");
}
}
1.2 UISwitch
//细节: 开关控件大小是固定的 (大小: 51X31)
UISwitch *mySwitch = [[UISwitch alloc] initWithFrame:CGRectMake(100, 100, 0, 0)];
mySwitch.onTintColor = [UIColor redColor];
mySwitch.tintColor = [UIColor blueColor];
mySwitch.thumbTintColor = [UIColor yellowColor];
[self.view addSubview:mySwitch];
//不要添加touchUpInside事件
[mySwitch addTarget:self action:@selector(dealSwitch:) forControlEvents:UIControlEventValueChanged];
方法实现
-(void)dealSwitch:(UISwitch *)s
{
NSLog(@"%d",s.isOn);
}
1.3 UIActivityIndicatorView
UIActivityIndicatorView *aiv = [[UIActivityIndicatorView alloc] initWithActivityIndicatorStyle:UIActivityIndicatorViewStyleGray];
aiv.center = CGPointMake(160, 240);
[self.view addSubview:aiv];
[aiv startAnimating];
//模拟下载完成
[NSTimer scheduledTimerWithTimeInterval:3 target:self selector:@selector(downloadFinish:) userInfo:aiv repeats:NO];
方法实现
-(void)downloadFinish:(NSTimer *)timer
{
UIActivityIndicatorView *aiv = timer.userInfo;
[aiv stopAnimating];
}
1.4 UISlider
UISlider *slider = [[UISlider alloc] initWithFrame:CGRectMake(100, 100, 100, 30)];

slider.maximumValue = 100;
slider.value = 50;
[self.view addSubview:slider];
//事件处理
[slider addTarget:self action:@selector(dealSlider:)
forControlEvents:UIControlEventValueChanged];
方法实现
-(void)dealSlider:(UISlider *)slider
{
NSLog(@"slider value = %f",slider.value);
}
1.5 UIStepper
//演示stepper和文本输入框的联合使用
// 控制购买商品的数据
UITextField *goodsNumTextFiled = [[UITextField alloc] initWithFrame:CGRectMake(20, 100, 70, 30)];
goodsNumTextFiled.borderStyle = UITextBorderStyleRoundedRect;

goodsNumTextFiled.text = @"1";
[self.view addSubview:goodsNumTextFiled];
UIStepper *stepper = [[UIStepper alloc] initWithFrame:CGRectMake(100, 100, 100, 30)];
stepper.minimumValue = 1;
stepper.maximumValue = 999999999999;
stepper.value = 2;
stepper.stepValue = 1; //每次+1
[self.view addSubview:stepper];
//添加事件处理
[stepper addTarget:self action:@selector(dealStepper:) forControlEvents:UIControlEventValueChanged];
方法实现
-(void)dealStepper:(UIStepper *)stepper
{
//取得textFiled指针
UITextField *tf = (UITextField *)[self.view viewWithTag:100];
tf.text = [NSString stringWithFormat:@"%d",(int)stepper.value];
}
1.6 UIProgressView
//创建的同时指定风格
UIProgressView *progressView = [[UIProgressView alloc] initWithProgressViewStyle:UIProgressViewStyleDefault];
progressView.frame = CGRectMake(100, 100, 200, 30);
//值的范围是0.0~1.0
progressView.progress = 0.5;
[self.view addSubview:progressView];
//模拟数据下载的过程
[NSTimer scheduledTimerWithTimeInterval:1/60.0 target:self selector:@selector(dealProgress:) userInfo:progressView repeats:YES];
方法实现
-(void)dealProgress:(NSTimer *)timer
{
timer.userInfo;
pv.progress += 0.004;
if(pv.progress >=1)
{
pv.progress=0;
}
}
1.7 UITextView
UITextView *textView = [[UITextView alloc] initWithFrame:CGRectMake(10, 30, 300, 450)];
textView.text = @"尽人事,听天命? 非也, 我命由我不由天。";
textView.backgroundColor = [UIColor orangeColor];
textView.font = [UIFont systemFontOfSize:18];
textView.tag = 100;
[self.view addSubview:textView];
1.8 UIActionSheet
UIActionSheet *action = [[UIActionSheet alloc] initWithTitle:@"分享" delegate:self cancelButtonTitle:@"取消按钮" destructiveButtonTitle:nil otherButtonTitles:@"新浪分享",@"微信分享",@"QQ分享",@"短信",@"邮件分享",nil];
[action showInView:self.view];
方法实现
- (void)actionSheet:(UIActionSheet *)actionSheet clickedButtonAtIndex:(NSInteger)buttonIndex
{
NSLog(@"buttonIndex = %ld",(long)buttonIndex);
}
1.9 UIAlertView
1.创建带有输入框的警告视图(带有一个输入框)
UIAlertView *alertView = [[UIAlertView alloc] init];
alertView.alertViewStyle = UIAlertViewStylePlainTextInput;
alertView.title = @"警告";
alertView.message = @"我是警告视图";
[alertView addButtonWithTitle:@"退出"];
[alertView show];
//处理警告视图的事件
//需要遵守协议 UIAlertViewDelegate
alertView.delegate = self;
方法实现
- (void)alertView:(UIAlertView *)alertView clickedButtonAtIndex:(NSInteger)buttonIndex {
//获取警告视图中得 输入框的文本, 如何获取?
UITextField *nameTextFiled = [alertView textFieldAtIndex:0];
NSLog(@"nameTextFiled.text = %@",nameTextFiled.text);
}
