IOS development-UISearchBar of the UIKit control (search bar) and uikituisearchbar
Today, you need to use the search control because of your needs. You have never used this control before, so I went to Baidu and found a complete article. Thank you for this author.

However, I have not found any attribute or method for changing the font size. Please let me know. Thank you!

Initialization: UISearchBar inherits from UIView. We can create a searchBar like creating a View.

1 UISearchBar *bar = [[UISearchBar alloc]initWithFrame:CGRectMake(20, 100, 250, 40)];2 [self.view addSubview:bar];

1 // you can set the searchBar search 2 @ property (nonatomic) UIBarStyle barStyle; 3 // enumeration: 4 typedef NS_ENUM (NSInteger, UIBarStyle) {5 UIBarStyleDefault = 0, // The default style is the white search box. The extra background is gray 6 UIBarStyleBlack = 1. // The Black style is displayed. The black search box 7 // The following two enumerations are disabled, same as the black style 8 UIBarStyleBlackOpaque = 1, // Deprecated. use UIBarStyleBlack 9 UIBarStyleBlackTranslucent = 2, // Deprecated. use UIBarStyleBlack and set the translucent property to YES10 };

Set text in the search box

1 @property(nonatomic,copy) NSString *text; 

The official explanation of this attribute is to display a line of text at the top of the search box, which is actually the background text. Description:

1 @property(nonatomic,copy) NSString *prompt; 

1 bar. prompt = @ "search box"; 2 bar. text = @ "321111111111111111111111111"

The effect is as follows:

 

It is the same as placeholder of other text input controls and disappears when the text is entered.

1 @property(nonatomic,copy) NSString *placeholder;  

Whether to display a book button on the right of the search box. The default value is NO. The effect of YES is as follows:

1 @property(nonatomic) BOOL showsBookmarkButton; 

Whether to display the cancel button. The default value is NO. The effect of YES is as follows:

1 @property(nonatomic) BOOL showsCancelButton;

Whether to display the search result button. The default value is "NO". The effect of "YES" is as follows:

1 @property(nonatomic) BOOL showsSearchResultsButton;

Select the search result button

1 @property(nonatomic, getter=isSearchResultsButtonSelected) BOOL searchResultsButtonSelected ;

Set the show cancel button

1 - (void)setShowsCancelButton:(BOOL)showsCancelButton animated:(BOOL)animated;

Setting this color value will affect the color of the cursor in the search box.

1 @property(nonatomic,retain) UIColor *tintColor;

Setting this color will affect the background color of the search box.

1 @property(nonatomic,retain) UIColor *barTintColor;

Set the overall style of the search box

1 @property (nonatomic) UISearchBarStyle searchBarStyle;

The enumerated values are as follows:

1 typedef NS_ENUM (NSUInteger, UISearchBarStyle) {2 UISearchBarStyleDefault, // currently adjust background, // Display Background 4 UISearchBarStyleMinimal // Do Not Display Background 5} partition (7_0 );

 

Set to translucent

1 @property(nonatomic,assign,getter=isTranslucent) BOOL translucent;

Whether to display the attachment selection button view in the search bar. To display this view, first set this attribute to YES, and then add a button to the button array to use the following attribute:

1 @property(nonatomic) BOOL showsScopeBar ;

Set the button title for the select button View

1 @property(nonatomic,copy) NSArray *scopeButtonTitles ；2 3 @property(nonatomic) NSInteger selectedScopeButtonIndex;

Set a default selected button

bar = [[UISearchBar alloc]initWithFrame:CGRectMake(20, 100, 250, 200)];bar.showsScopeBar=YES;bar.scopeButtonTitles = @[@"12",@"2",@"3",@"4"];

Secondary view of the keyboard

1 @property (nonatomic, readwrite, retain) UIView *inputAccessoryView;

Set the background pattern of the search box

1 @property(nonatomic,retain) UIImage *backgroundImage;

Set the background pattern of the affiliated selection button View

1 @property(nonatomic,retain) UIImage *scopeBarBackgroundImage;

This method can be used to set and obtain the background pattern of the search box in a certain state enumeration.

-(Void) setBackgroundImage :( UIImage *) backgroundImage forBarPosition :( UIBarPosition) barPosition barMetrics :( UIBarMetrics) barMetrics;

-(UIImage *) backgroundImageForBarPosition :( UIBarPosition) barPosition barMetrics :( UIBarMetrics) barMetrics

This method is used to set and obtain the background pattern of TextField in the search box.

-(Void) setSearchFieldBackgroundImage :( UIImage *) backgroundImage forState :( UIControlState) state;

-(UIImage *) searchFieldBackgroundImageForState :( UIControlState) state;

This method is used to obtain and set the icon image pattern in the search bar.

-(Void) setImage :( UIImage *) iconImage forSearchBarIcon :( UISearchBarIcon) icon state :( UIControlState) state;

-(UIImage *) imageForSearchBarIcon :( UISearchBarIcon) icon state :( UIControlState) state;

This method is used to set and obtain the background pattern of the additional selection button view in the search box.

-(Void) setScopeBarButtonBackgroundImage :( UIImage *) backgroundImage forState :( UIControlState) state;

-(UIImage *) scopeBarButtonBackgroundImageForState :( UIControlState) state;

This method is used to obtain and set the pattern of the switch button in the additional selection button view.

-(Void) setScopeBarButtonDividerImage :( UIImage *) dividerImage forLeftSegmentState :( UIControlState) leftState rightSegmentState :( UIControlState) rightState;

-(UIImage *) scopeBarButtonDividerImageForLeftSegmentState :( UIControlState) leftState rightSegmentState :( UIControlState) rightState;

This method is used to set and retrieve the font attribute Dictionary of the title Text of the switch button.

-(Void) setScopeBarButtonTitleTextAttributes :( NSDictionary *) attributes forState :( UIControlState) state;

-(NSDictionary *) scopeBarButtonTitleTextAttributesForState :( UIControlState) state;

Position offset of search text in the search box

@ Property (nonatomic) UIOffset searchFieldBackgroundPositionAdjustment;

Position offset of textfield in the search box

@ Property (nonatomic) UIOffset searchTextPositionAdjustment;

Set the position offset of the image in the search bar

-(Void) setPositionAdjustment :( UIOffset) adjustment forSearchBarIcon :( UISearchBarIcon) icon;

-(UIOffset) positionAdjustmentForSearchBarIcon :( UISearchBarIcon) icon;

The image enumeration is as follows:

Typedef NS_ENUM (NSInteger, UISearchBarIcon) {UISearchBarIconSearch, // search icon UISearchBarIconClear, // clear icon UISearchBarIconBookmark, // book icon marker, // result list icon };

The following are some proxy methods for the search box control:

Callback when editing is to begin. If NO is returned, it cannot be edited.

-(BOOL) searchBarShouldBeginEditing :( UISearchBar *) searchBar;

Callback when editing is started

-(Void) searchBarTextDidBeginEditing :( UISearchBar *) searchBar;

Callback when editing is to end

-(BOOL) searchBarShouldEndEditing :( UISearchBar *) searchBar;

Callback with edited end

-(Void) searchBarTextDidEndEditing :( UISearchBar *) searchBar;

Callback for editing text changes

-(Void) searchBar :( UISearchBar *) searchBar textDidChange :( NSString *) searchText;

The callback before the edited text changes. If NO is returned, the new edited text cannot be added.

-(BOOL) searchBar :( UISearchBar *) searchBar shouldChangeTextInRange :( nsange) range replacementText :( NSString *) text;

Search button click callback

-(Void) searchBarSearchButtonClicked :( UISearchBar *) searchBar;

Book button click callback

-(Void) searchBarBookmarkButtonClicked :( UISearchBar *) searchBar;

Call back when the cancel button is clicked

-(Void) searchBarCancelButtonClicked :( UISearchBar *) searchBar;

Callback for clicking the search result button

-(Void) searchBarResultsListButtonClicked :( UISearchBar *) searchBar;

Callback triggered by the switch button in the additional view of the search bar

-(Void) searchBar :( UISearchBar *) searchBar selectedScopeButtonIndexDidChange :( NSInteger) selectedschange;
