ios悬浮按钮的实现
我在网上找了很久没有找到一个悬浮按钮,所以才决定自己做一个,效果还不错。
github 下载demo:https://github.com/MartinLi841538513/MartinDemos (一切以demo为准)
集成大法:
一,首先引入MLFloatButton.h .m .xib 文件(在demo含)
二,在controller中集成成MLFloatButton
引入#import "MLFloatButton.h"
实现MLFloatButtonDelegate协议以及他的方法buttonTouchAction
然后通过loadFromNibWithFrame初始化floatButton(这里一定要在viewWillAppear实现,否则,popBack将会看不到效果)
prepareForSegue是跳转到另外一个界面也要能够显示该floatButton(通常我们需要这么做),此时我们需要重新设置代理和父视图。并在下一个controller的viewWillAppear实现addSubview,以及协议方法。
#import "FloatButtonViewController.h" #import "MLFloatButton.h" #import "SecondViewController.h" @interface FloatButtonViewController ()<MLFloatButtonDelegate> { MLFloatButton *floatButton; } @end @implementation FloatButtonViewController -(void)viewWillAppear:(BOOL)animated{ [super viewWillAppear:animated]; floatButton = [MLFloatButton loadFromNibWithFrame:CGRectMake(100, 100, 32, 32) addTarget:self InSuperView:self.view];//这里一定要在viewWillAppear实现,否则,popBack将会看不到效果 } #pragma mark - Navigation - (void)prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender { if ([segue.identifier isEqualToString:@"FloatButtonPush"]) { SecondViewController *target = segue.destinationViewController; target.floatButton = floatButton; target.floatButton.floatButtonDelegate = (id)target; //重新设置代理controller } } #pragma MLFloatButtonDelegate -(void)buttonTouchAction{ NSLog(@"button action"); } @end
在SecondViewController.h
#import "MLFloatButton.h" @interface SecondViewController : UIViewController @property(nonatomic,strong)MLFloatButton *floatButton; @end
在SecondViewController.m
#import "SecondViewController.h" @interface SecondViewController ()<MLFloatButtonDelegate> @end @implementation SecondViewController -(void)viewWillAppear:(BOOL)animated{ [super viewWillAppear:animated]; [self.floatButton showInFatherView:self.view]; } #pragma MLFloatButtonDelegate -(void)buttonTouchAction{ NSLog(@"SecondViewController floatButton touched"); } @end
