[iOS底工控件,ios底子控件
A.需求 1. 上学DatePicker的着力配置
2.选用TextField召唤钦命项指标输入键盘View,这里运用DatePicker
3.给输入键盘上方加上多个UIToolBar,达成如关闭键盘等效能
B.DatePicker使用 1.DatePicker的首要性属性 1 // 1.创建DatePicker 2
UIDatePicker *datePicker = [[UIDatePicker alloc] init]; 3 //
2.设置形式 4 [datePicker setDatePickerMode:UIDatePickerModeDate]; 5 //
3.设置locale 6 [datePicker setLocale:[NSLocale
localeWithLocaleIdentifier:@"zh_CN"]]; 7 //
4.设置textField的响应键盘为DatePicker 8 [self.textField
setInputView:datePicker]; 1 // 1.创建UIToolBar 2 UIToolbar *toolBar
= [[UIToolbar alloc] init]; 3 // toolBar.backgroundColor = [UIColor
grayColor]; 4 // toolBar.tintColor = [UIColor blueColor]; 5
toolBar.barTintColor = [UIColor grayColor]; //
那个才是UIToolBar的背景观 6 toolBar.frame = CGRectMake(0, 0, 320, 44卡塔尔国;
// 必需设置好size,UIToolBar工夫显得,不然只好显示Item,且不能点击 7 //
2.成立Item 8 UIBarButtonItem *item1 = [[UIBarButtonItem alloc]
initWithTitle:@"上一个" style:UIBarButtonItemStylePlain target:self
action:@selector(previousClicked)]; 9 10 UIBarButtonItem *item2 =
[[UIBarButtonItem alloc] initWithTitle:@"下一个"
style:UIBarButtonItemStylePlain target:self
action:@selector(nextClicked)]; 11 12 UIBarButtonItem *item3 =
[[UIBarButtonItem alloc] initWithTitle:@"完成"
style:UIBarButtonItemStylePlain target:self
action:@selector(finishClicked)]; 13 14 // 间隙Item 15 UIBarButtonItem
*spaceItem = [[UIBarButtonItem alloc]
initWithBarButtonSystemItem:UIBarButtonSystemItemFlexibleSpace
target:self action:nil]; 16 17 // 3.添加Item到UIToolBar 18
toolBar.items = @[item1, item2, spaceItem, item3]; 19 20 //
4.增加UIToolBar到键盘上方,设置为textField的帮手视图 21
self.textField.inputAccessoryView = toolBar;

DatePicker展现时间的控件:有暗中同意宽度,不用安装数据源和代办;
- 在UIToolBar 上丰盛相近的控件
能够在toolBar上增加任何View。其实它的法规是把你要丰富的View先加到UIBarButtonItem里头,最终再把UIBarButtonItem数组叁次性放到toolbar的items里面。
怎么着改成普通话的?
self.navigationController.navigationBar.barStyle = UIBarStyleBlackOpaque ;
1.先是,咱们看一下UIBbarButtonItem有怎么着开首化方法,这也得以看看,它能够被定义为何东东,然后加到UIToolBar上边去。
1> 查看当前系统是还是不是为华语,把模拟器改成普通话;
//设置工具栏的背景颜色
听别人讲SDK的文书档案,大家得以窥见UIBarButtonItem好似下三种初阶化的主意:
2> 属性,locale接收地面;
NSMutableArray *buttons = [[NSMutableArray alloc]initWithCapacity:4];
-initWithTitle(添加button用这个)
借使默许展现不相符必要,时间有两种情势能够设置,在model中开展设置,时间可以自定义。
//设置加多按钮的数码
-initWithImage
安装最时辰间和最大时间,超过就能自动回到最时辰间;
UIBarButtonItem *flexibleSpaceItem;
-initWithBarButtonSystemItem(增多体系自定义的button,形状跟大小都曾经固化了)上边链接里面有按键图片样式
最大的用项在于自定义键盘:弹出三个日期接受器出来;
flexibleSpaceItem =[[[UIBarButtonItem alloc]
initWithBarButtonSystemItem:UIBarButtonSystemItemFlexibleSpace
-initWithCustomView(加多除此之外button以外的View)
UIDatePicker *picker = [[UIDatePicker alloc] init];
target:self
第4种方法正是大家加多各类调味品的接口,所现在天的不同凡响其余也是它。
[picker setLocale:[NSLocale localeWithLocaleIdentifier:@"zh-CN"]];
action:NULL]autorelease];
2.在UIToolBar上边加多Title
picker.datePickerMode = UIDatePickerModeDate;
[buttons addObject:flexibleSpaceItem];
view plaincopy to clipboardprint?
_viewfield = [[UITextField alloc] initWithFrame:CGRectMake(20, button.frame.origin.y + 30 +10, [UIScreen mainScreen].bounds.size.width-40, 40)];
//UIBarButtonSystemItemFixedSpace和UIBarButtonSystemItemFlexibleSpace都是系统提供的用于占位的开关样式。
UIToolbar *myToolBar = [[UIToolbar alloc] initWithFrame:
_viewfield.keyboardType = UIKeyboardTypeDefault;
//使开关与开关之间有间隔
CGRectMake(0.0f, 0.0f, 320.0f, 44.0f)];
_view田野先生.placeholder = @"请输入密码";
UIBarButtonItem *Item;
_viewfield.leftViewMode = UITextFieldViewModeAlways;
Item = [[UIBarButtonItem alloc]
NSMutableArray *myToolBarItems = [NSMutableArray array];
_viewfield.contentVerticalAlignment = UIControlContentVerticalAlignmentCenter;
initWithImage:[UIImage imageNamed:@"down.png"]
[myToolBarItems addObject:[[[UIBarButtonItem alloc]
_viewfield.textColor = [UIColor darkTextColor];
style:UIBarButtonItemStylePlain
initWithTitle:@"myTile"
_viewfield.font = [UIFont fontWithName:@"Arial" size:20.0];
target:self
style:UIBarButtonItemStylePlain
_viewfield.clearButtonMode = UITextFieldViewModeAlways;
action:@selector(decrement:)];
target:self
_viewfield.borderStyle = UITextBorderStyleRoundedRect;
[buttons addObject:Item];
action:@selector(action)] autorelease]];
_viewfield.secureTextEntry = YES;
//加多先是个Logo开关
[myToolBar setItems:myToolBarItems animated:YES];
_viewfield.returnKeyType = UIReturnKeyDone;
Item = [[UIBarButtonItem alloc]
[myToolBar release];
_viewfield.delegate = self;
initWithImage:[UIImage imageNamed:@"up.png"]
[myToolBarItems];
[self.view addSubview:_viewfield];
style:UIBarButtonItemStylePlain
_viewfield.inputView = picker;
target:self
setItems传入值大概说items是一个对象数组。
UIToolbar *tool = [[UIToolbar alloc] init];
action:@selector(increment:)];
3.在UIToolBar上面增添image
tool.barTintColor = [UIColor brownColor];
[buttons addObject:Item];
view plaincopy to clipboardprint?
tool.frame = CGRectMake(0, 0, [UIScreen mainScreen].bounds.size.width, 44);
//加多第叁个Logo开关
[myToolBarItems addObject:[[[UIBarButtonItem alloc]
UIBarButtonItem *item1 = [[UIBarButtonItem alloc] initWithTitle:@"上一个" style:UIBarButtonItemStylePlain target:self action:@selector(itemClick:)];
flexibleSpaceItem = [[[UIBarButtonItem alloc]
initWithImage:[UIImage imageNamed:@"myImage.png"]
UIBarButtonItem *item2 = [[UIBarButtonItem alloc] initWithTitle:@"下一个" style:UIBarButtonItemStylePlain target:self action:@selector(itemClick:)];
initWithBarButtonSystemItem:UIBarButtonSystemItemFlexibleSpace
style:UIBarButtonItemStylePlain
UIBarButtonItem *space = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemFlexibleSpace target:nil action:nil];
target:self
target:self
UIBarButtonItem *item3 = [[UIBarButtonItem alloc] initWithTitle:@"完成" style:UIBarButtonItemStylePlain target:self action:@selector(itemClick:)];
action:NULL]autorelease];
action:@selector(action)]];
tool.items = @[item1, item2, space, item3];
[buttons addObject:flexibleSpaceItem];
4.在UIToolBar上边增多SystemItem
_viewfield.inputAccessoryView = tool;
UIToolbar *toolBar = [[UIToolbar alloc]init];
[myToolBarItems addObject:[[[UIBarButtonItem alloc]
toolBar.barStyle = UIBarStyleBlackOpaque ;
initWithBarButtonSystemItem:UIBarButtonSystemItemPlay
[toolBar setItems:buttons animated:YES];
target:self
[toolBar sizeToFit];
action:@selector(action)] autorelease]];
self.navigationItem.titleView = toolBar ;
Note:
//将那几个开关增添到toolbar上面去
initWithBarButtonSystemItem初始化:
2.在UIToolBar 上添加 UILabel
- (id)initWithBarButtonSystemItem:(UIBarButtonSystemItem)systemItem target:(id)target action:(SEL)action
UILabel *myLabel = [[UILabel alloc] initWithFrame:CGRectMake(40.0f, 20.0f, 45.0f, 10.0f)];
Defines system defaults for commonly used items.
myLabel.font=[UIFont systemFontOfSize:10];
typedef enum {
myLabel.backgroundColor = [UIColor whiteColor];
UIBarButtonSystemItemDone,
myLabel.textAlignment=UITextAlignmentCenter;
UIBarButtonSystemItemCancel,
myLabel.text = @"aa";
UIBarButtonSystemItemEdit,
UIBarButtonItem *myButtonItem = [[UIBarButtonItem alloc]initWithCustomView:myLabel];
UIBarButtonSystemItemSave,
[buttons addObject: myButtonItem]; //添Gavin本
UIBarButtonSystemItemAdd,
3.在UIToolBar 上添加 滑动条UIProgressView
UIBarButtonSystemItemFlexibleSpace,
UIProgressView *myProgress = [[UIProgressView alloc] initWithFrame:
UIBarButtonSystemItemFixedSpace,
CGRectMake(65.0f, 20.0f, 90.0f, 10.0f)];
UIBarButtonSystemItemCompose,
UIBarButtonItem *myButton = [[UIBarButtonItem alloc]initWithCustomView:myProgress];
UIBarButtonSystemItemReply,
[buttons addObject: myButton]; //增加滑动条
UIBarButtonSystemItemAction,
4.在UIToolBar上增多UISegmentedControl UISegmentedControl的作用是足以让有同生龙活虎效果的按键紧密的排列在豆蔻梢头道
UIBarButtonSystemItemOrganize,
NSArray *buttonNames = [NSArray arrayWithObjects:@"One", @"Two", @"Three", @"Four", nil];
UIBarButtonSystemItemBookmarks,
UISegmentedControl* segmentedControl = [[UISegmentedControl alloc] initWithItems:buttonNames];
UIBarButtonSystemItemSearch,
segmentedControl.momentary = YES;
UIBarButtonSystemItemRefresh,
//要是它棉被服装置为YES,选按时亮 点击过后不亮 假若注释掉选中的项一贯被显示高亮
UIBarButtonSystemItemStop,
[(UITextView *)self.view setText:@""];
UIBarButtonSystemItemCamera,
segmentedControl.autoresizingMask = UIViewAutoresizingFlexibleWidth;//若出界的话则自动扩张其调幅
UIBarButtonSystemItemTrash,
segmentedControl.segmentedControlStyle = UISegmentedControlStyleBar;
UIBarButtonSystemItemPlay,
segmentedControl.frame = CGRectMake(0, 0, 400, 30);
UIBarButtonSystemItemPause,
[segmentedControl addTarget:self action:@selector(segmentAction:)
UIBarButtonSystemItemRewind,
forControlEvents:UIControlEventValueChanged];
UIBarButtonSystemItemFastForward,
//self.navigationItem.titleView = segmentedControl;
UIBarButtonSystemItemUndo, // iPhoneOS 3.0
[self.navigationController.navigationBar addSubview: segmentedControl]; //与地点一句话相像的效果
UIBarButtonSystemItemRedo, // iPhoneOS 3.0
-(void) segmentAction: (id) sender
} UIBarButtonSystemItem;
{
5.在UIToolBar下边增多其他种种控件,最轻松意义,最棒玩的,笔者把它坐落于最终来说。大家应用initWithCustomView来成功,
switch([sender selectedSegmentIndex] + 1)
此处须要看一下initWithCustomView的概念:
{
- (id)initWithCustomView:(UIView *)customView
case 1: [(UITextView *) self.view setText:@"nnOne"]; break;
能够见见,它的参数是二个VIEW,所以我们给它的配料要科学哦才行哦,不然,你就等着时间DIDADIDA的消亡吧.
case 2: [(UITextView *) self.view setText:@"nnTwo"]; break;
A>加二个按键switch:
case 3: [(UITextView *) self.view setText:@"nnThree"]; break;
[myToolBarItems addObject:[[[UIBarButtonItem alloc]
case 4: [(UITextView *) self.view setText:@"nnFour"]; break;
initWithCustomView:[[[UISwitch alloc] init] autorelease]]
default: break;
autorelease]];
}
B>加三个开关UIBarButtonItem
}
UIBarButtonItem *myButton = [[[UIBarButtonItem alloc]
5.在UIToolBar上添加Title
initWithTitle:@"myButton"
UIToolbar *myToolBar = [[UIToolbar alloc] initWithFrame:
style:UIBarButtonItemStyleBordered
CGRectMake(0.0f, 0.0f, 320.0f, 44.0f)];
target:self
NSMutableArray *myToolBarItems = [NSMutableArray array];
action:@selector(action)]autorelease];
[myToolBarItems addObject:[[[UIBarButtonItem alloc]
get1Button.width = 50;
initWithTitle:@"myTile"
[myToolBarItems addObject:myButton];
style:UIBarButtonItemStylePlain
C>加一个文本Label
target:self
view plaincopy to clipboardprint?
action:@selector(action)] autorelease]];
UILabel *myLabel = [[UILabel alloc] initWithFrame:CGRectMake(40.0f, 20.0f, 45.0f, 10.0f)];
[myToolBar setItems:myToolBarItems animated:YES];
myLabel.font=[UIFont systemFontOfSize:10];
6.在UIToolBar上添加image
//myLabel.backgroundColor = [UIColor clearColor];
[myToolBarItems addObject:[[[UIBarButtonItem alloc]
//myLabel.textAlignment=UITextAlignmentCenter;
initWithImage:[UIImage imageNamed:@"myImage.png"]
UIBarButtonItem *myButtonItem = [[UIBarButtonItem alloc]initWithCustomView:myLabel];
style:UIBarButtonItemStylePlain
[myToolBarItems addObject: myButtonItem];
target:self
[mylabel release];
action:@selector(action)]];
[myButtonItem release];
7.在UIToolBar上添加SystemItem
[myToolBarItems addObject:[[[UIBarButtonItem alloc]
D>加三个进度条UIProgressView
initWithBarButtonSystemItem:UIBarButtonSystemItemPlay
UIProgressView *myProgress = [[UIProgressView alloc] initWithFrame:CGRectMake(65.0f, 20.0f, 90.0f, 10.0f)];
target:self
UIBarButtonItem *myButtonItem = [[UIBarButtonItem alloc]initWithCustomView:myProgress];
action:@selector(action)] autorelease]];
[myToolBarItems addObject: myButtonItem];
[myProgress release];
[myButtonItem release];
能够加运用initWithCustomView制作各样button,这里就不在此二个二个在加了。作者想你应当也曾经调整了什么加多种种buttonItem的法门了。
