Premise: At that time saw someone write this similar assistivetouch demo, but there is a problem, the first can not change the location, the second switch page cannot be used, the third run occasionally crashes. Then he went to the Niang, the forum have looked up some information, and then combined to write a demo.
Idea: the implementation of global needs in the APPDELEGATE.M file Didfinishlaunchingwithoptions method inside the implementation
1. Create a new class that inherits from UIWindow Assistivetouch

Code in the AssistiveTouch.h file

#import <UIKit/UIKit.h> @interface assistivetouch:uiwindow{    UIButton *_button;} -(ID) initWithFrame: (CGRect) frame; @end

Code in the ASSISTIVETOUCH.M file

#import "ASSISTIVETOUCH.H" @interface Assistivetouch () @end @implementation assistivetouch/*//only override DrawRect: If you perform custom drawing.//an empty implementation adversely affects performance during animation.-(void) DrawRect: (    CGRect) Rect {//Drawing code}*/-(ID) initWithFrame: (cgrect) frame{self = [super Initwithframe:frame];        if (self) {self.backgroundcolor = [uicolor Clearcolor];        Self.windowlevel = Uiwindowlevelalert + 1;//This sentence is very important [self makekeyandvisible];        _button = [UIButton buttonwithtype:uibuttontypecustom];        _button.backgroundcolor = [Uicolor Graycolor];        _button.frame = CGRectMake (0, 0, frame.size.width, frame.size.height);        _button.layer.cornerradius = FRAME.SIZE.WIDTH/2;        [_button addtarget:self Action: @selector (choose) forcontrolevents:uicontroleventtouchupinside]; [Self addsubview:_button];//puts a drag gesture to change the position of the control uipangesturerecognizer *pan = [[Uipangesturerecognizer alloc] Initwit Htarget:self Action: @selector (changepostion:)];    [_button Addgesturerecognizer:pan]; } return self;} Button Event-(void) choose{NSLog (@ "hover window");}    Gesture Event--change position-(void) Changepostion: (Uipangesturerecognizer *) pan{cgpoint point = [Pan translationinview:self];    CGFloat width = [UIScreen mainscreen].bounds.size.width;    CGFloat height = [UIScreen mainscreen].bounds.size.height;    CGRect originalframe = self.frame; if (originalframe.origin.x >= 0 && originalframe.origin.x+originalframe.size.width <= width) {origin    Alframe.origin.x + = Point.x;        } if (originalframe.origin.y >= 0 && originalframe.origin.y+originalframe.size.height <= height) {    ORIGINALFRAME.ORIGIN.Y + = Point.y;    } self.frame = Originalframe;    [Pan Settranslation:cgpointzero inview:self];    if (pan.state = = Uigesturerecognizerstatebegan) {_button.enabled = NO; }else if (pan.state = = uigesturerecognizerstatechanged) {} else {CGRect frame = Self.frame;        Whether the record is out of bounds BOOL isover = NO;            if (frame.origin.x < 0) {frame.origin.x = 0;        Isover = YES;            } else if (Frame.origin.x+frame.size.width > width) {frame.origin.x = Width-frame.size.width;        Isover = YES;            } if (Frame.origin.y < 0) {frame.origin.y = 0;        Isover = YES;            } else if (Frame.origin.y+frame.size.height > height) {frame.origin.y = Height-frame.size.height;        Isover = YES;            } if (isover) {[UIView animatewithduration:0.3 animations:^{self.frame = frame;        }];    } _button.enabled = YES; }} @end
