iOS Summary _ Achieve UIButton graphics and text mix, while displaying words and pictures

We often need to use buttons that require text and images to be displayed simultaneously, for example:

We need to define a UIButton subclass.

Implementation file

-(ID) initWithFrame: (cgrect) frame

{

self = [super initwithframe: frame];

if (self) {

//Can be adjusted according to your own needs

self. Titlelabel. TextAlignment=nstextalignmentright;

Self. Titlelabel. font=[uifontsystemfontofsize:14.0];

self. ImageView . Contentmode = Uiviewcontentmodeleft;

}

return self;

}

Methods for overriding parent class UIButton

Rect with a more button set and returns the text label of the RECT

-(cgrect) Titlerectforcontentrect: (cgrect) contentrect

{

cgfloat Titlew = contentrect. size. width-+;

cgfloat Titleh = contentrect. size. height;

cgfloat Titlex = 0;

cgfloat Titley = 0;

Contentrect = (cgrect) {{Titlex,titley},{titlew,titleh}};

return Contentrect;

}

Rect with a more button set and returns a Uiimageview rect

-(cgrect) Imagerectforcontentrect: (cgrect) contentrect

{

cgfloat Imagew = ;

cgfloat Imageh = ;

cgfloat ImageX = contentrect. size. width-up;

cgfloat imagey = 2.5;

Contentrect = (cgrect) {{Imagex,imagey},{imagew,imageh}};

return Contentrect;

}

Using subclasses of UIButton

Yxpbutton *selectareabutton=[[yxpbuttonalloc] initwithframe:cgrectmake (5, +) ];

[Selectareabutton settitle:@ "graphic mixed"forstate: UIControlStateNormal];

[Selectareabutton setimage: [UIImageimagenamed:@ "Location" ]forstate:uicontrolstatenormal];

[Selectareabutton settitlecolor: [uicolorwhitecolor] Forstate:uicontrolstatenormal];

[NavigationbgviewAddsubview: Selectareabutton];

So that you can implement a button of the graphic mixed
