Custom Uisearchbar "Cancel button"

Requirements: Uisearchbar the Cancel button, there is no public method to modify its properties. But we can still set the "Cancel button" by traversing Uisearchbar's child controls.

effect: Change the "Cancel" text in the Uisearchbar Cancel button to "search".

The code is as follows:

-(void) Setsearchbar: (Uisearchbar *) searchbar{

Uisearchbar *searchbar = [[Uisearchbar alloc] Initwithframe:cgrectmake (0, 0, Kscreenwidth, 44)];

[Searchbar Setshowscancelbutton:yes]; //Show right Cancel button (required)

/*1. Traverse Uisearchbar's child control, find Uinavgationbutton in "Level two child control", which is the "Cancel button" we want to change;

2. Get Uinagationbar (inherit from UIButton) and modify its properties;

*/

For (UIView *view in [[Searchbar.subviews Lastobject] subviews]) {

if ([View Iskindofclass:[uibutton class]]) {

UIButton *cancelbtn = (UIButton *) view;

[Cancelbtn settitle:@ "search" forstate:uicontrolstatenormal]; //Key steps

}

}

[Self.view Addsubview:searchbar];

}

Effect:
