Search.showssearchresultsbutton =yes;

Set the right end of the control to display the search results button---Replace the available pictures

[Search Setimage:[uiimage imagenamed:@ "qiyi.png"]forsearchbaricon:uisearchbariconresultslist state: UIControlStateNormal];

pragma mark-Search bar Bottom selection bar

Copy Code code as follows:

The selection bar in the lower part of the search bar, and the contents of the array are the button headings

Search.scopebuttontitles = [Nsarray arraywithobjects:@ "IOS", @ "Android", @ "IPhone", nil];

Enter the index of the default selection bar button at the bottom of the search bar (that is, which selection bar appears first)

Search.selectedscopebuttonindex = 2;

Controls whether the selection bar in the bottom of the search bar is displayed (if shown, modify the search frame, not shown 80 is enough)

Set the bottom of the search bar background picture

Search.scopebarbackgroundimage = [UIImage imagenamed:@ "Qiyi.png"];

pragma mark-Agreement uisearchbardelegate

(not explained, see name, already very obvious)

Copy Code code as follows:

@ Edit Text

When Uisearchbar gets the focus and starts editing, execute the method

(BOOL) Searchbarshouldbeginediting: (Uisearchbar *) Searchbar; Return NO to not become-a-responder

(void) Searchbartextdidbeginediting: (Uisearchbar *) searchbar{//Called when text starts editing

[Searchbar Setshowscancelbutton:yes Animated:yes]; Animated Display Cancel button

}

(BOOL) Searchbarshouldendediting: (Uisearchbar *) Searchbar; Return NO to not resign-a-responder

(void) Searchbartextdidendediting: (Uisearchbar *) Searchbar; Called when text ends editing

(void) Searchbar: (Uisearchbar *) Searchbar textdidchange: (NSString *) searchtext{//called when text changes (including CL Ear

@ When the search content changes, execute the method. Useful, real time search can be implemented

}

Copy Code code as follows:

(BOOL) Searchbar: (Uisearchbar *) Searchbar Shouldchangetextinrange: (nsrange) Range Replacementtext: (NSString *) TextNS                 _available_ios (3_0); Called before text changes
@ button click

(void) searchbarsearchbuttonclicked: (Uisearchbar *) Searchbar; Called when keyboard search button pressed

(void) searchbarbookmarkbuttonclicked: (Uisearchbar *) Searchbar; Called when Bookmark button pressed

(void) searchbarcancelbuttonclicked: (Uisearchbar *) searchbar{//Called when Cancel button pressed

[Searchbar Setshowscancelbutton:no Animated:no]; Cancel Button Recycle

[Searchbar Resignfirstresponder]; Cancel first Response value, keyboard recycle, end of search

}

(void) searchbarresultslistbuttonclicked: (Uisearchbar *) Searchbarns_available_ios (3_2);//called When search results Button pressed

(void) Searchbar: (Uisearchbar *) Searchbar Selectedscopebuttonindexdidchange: (Nsinteger) Selectedscopens_available_ IOS (3_0);

Data Brush Select class: Nspredicate

Copy Code code as follows:

@ assume: Nsarray array = [[Nsarray alloc]initwithobjects:@ ' Luna ', @ "Moon", @ "", @ "Lion", @ "Coco", nil];

The processing of data occurs mainly in this method

(void) Searchbar: (Uisearchbar *) Searchbar textdidchange: (NSString *) searchtext{

Method One: ([c] case-insensitive [d] does not distinguish between pronounced symbols, that is, no accent mark [CD] is neither case sensitive nor distinguishes the pronunciation symbol. )

nspredicate * predicate = [nspredicate predicatewithformat:@ "SELF CONTAINS [CD]%@", SearchText];

Array provides a quick traversal, the type returned is Nsarray

NSLog (@ "%@", [_array filteredarrayusingpredicate:predicate]);

Method Two:

for (int i = 0; I count); i++) {

if ([predicate evaluatewithobject:[_array Objectatindex:i]]) {

NSLog (@ "%@", [arrayobjectatindex:i]);

}

}

}
