[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;        

A.需要 1. 上学DatePicker的主导配置2.应用TextField召唤钦命项目标输入键盘View，这里运用DatePicker3.给输入键盘上方加...

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；

1. 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。
