Objective-C自定义弹层UIActionSheet

系统弹层不好看？那就自己封装一个弹层小控件吧~

新建一个类，继承自UIView，（类名MessagePopView）

头文件中的代码：

#import <UIKit/UIKit.h>

@interface MessagePopView : UIView

-(void) hidePopView;

-(void) showPopView;

@end

.m文件实现：

#import "MessagePopView.h"

#define SCREEN_WIDTH ([UIScreen mainScreen].bounds.size.width)

#define SCREEN_HEIGHT ([UIScreen mainScreen].bounds.size.height)

@interface MessagePopView ()

@property (strong, nonatomic)UIImageView *imgView;

@property (strong, nonatomic)UIImageView *imgViewMessage;

@property (strong, nonatomic)UILabel *backgroundLabel;

@property (strong, nonatomic)UIView *contentView;

@property (nonatomic, strong)UIButton *clearMessageBtn;

@property (nonatomic, strong)UIButton *cancelBtn;

@end

@implementation MessagePopView

- (instancetype)initWithFrame:(CGRect)frame{

if (self = [super initWithFrame:frame]) {

[self drawView];

}

return self;

}

- (void)drawView{

//半透明背景

self.imgView = [[UIImageView alloc]initWithImage:[UIImage imageNamed:@"show_pop_view_bk"]];

self.imgView.frame = CGRectMake(0, 0, SCREEN_WIDTH, SCREEN_HEIGHT);

self.imgView.userInteractionEnabled = YES;

UITapGestureRecognizer *tapGesture = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(hidePopView)];//添加手势，点击隐藏

[self.imgView addGestureRecognizer:tapGesture];

[self addSubview:self.imgView];

//弹层容器视图

self.contentView = [[UIView alloc]init];

self.contentView.frame = CGRectMake(0, SCREEN_HEIGHT, SCREEN_WIDTH, 100);

//弹层背景图

self.imgViewMessage = [[UIImageView alloc]initWithImage:[UIImage imageNamed:@"show_manage_pop_view_bk"]];

self.imgViewMessage.frame = CGRectMake(0, 0, SCREEN_WIDTH, 100);

self.imgViewMessage.userInteractionEnabled = YES;

[self.contentView addSubview:self.imgViewMessage];

self.clearMessageBtn = [UIButton buttonWithType:UIButtonTypeCustom];

self.clearMessageBtn.frame = CGRectMake(0, 0, SCREEN_WIDTH, 45);

self.clearMessageBtn.backgroundColor = [UIColor whiteColor];

[self.clearMessageBtn setTitle:@"确认" forState:UIControlStateNormal];

[self.clearMessageBtn setTitleColor:[UIColor redColor] forState:UIControlStateNormal];

[self.clearMessageBtn addTarget:self action:@selector(MessageClick) forControlEvents:UIControlEventTouchUpInside];

[self.contentView addSubview:self.clearMessageBtn];

self.cancelBtn = [UIButton buttonWithType:UIButtonTypeCustom];

self.cancelBtn.frame = CGRectMake(0, 55, SCREEN_WIDTH, 45);

self.cancelBtn.backgroundColor = [UIColor whiteColor];

[self.cancelBtn setTitleColor:[UIColor blackColor] forState:UIControlStateNormal];

[self.cancelBtn setTitle:@"取消" forState:UIControlStateNormal];

[self.cancelBtn addTarget:self action:@selector(hidePopView) forControlEvents:UIControlEventTouchUpInside];

[self.contentView addSubview:self.cancelBtn];

[self.imgView addSubview:self.contentView];

}

//点击确认的事件

- (void)MessageClick{

/**

* 这里添加其他操作

*/

[self hidePopView];

}

//隐藏弹层

-(void) hidePopView

{

[UIView animateWithDuration:0.3 animations:^{

self.contentView.frame = CGRectMake(0.0f, SCREEN_HEIGHT + 100 , self.frame.size.width, self.contentView.frame.size.height );

} completion:^(BOOL finished) {

self.hidden = YES;

[self removeFromSuperview];

}];

}

//显示弹层

-(void) showPopView

{

[UIView animateWithDuration:0.5 animations:^{

self.hidden = NO;

self.contentView.frame = CGRectMake(0.0f, SCREEN_HEIGHT - 100, self.frame.size.width, self.contentView.frame.size.height);

}];

self.imgView.hidden = NO;

}

@end

调用：

- (void)viewDidLoad {

[super viewDidLoad];

// Do any additional setup after loading the view, typically from a nib.

UIButton *button = [UIButton buttonWithType:UIButtonTypeCustom];

button.backgroundColor = [UIColor redColor];

button.frame = CGRectMake(100, 100, 100, 100);

[button setTitle:@"点我" forState:UIControlStateNormal];

[self.view addSubview:button];

[button addTarget:self action:@selector(show) forControlEvents:UIControlEventTouchUpInside];

}

- (void)show{

_MessagePopView = [MessagePopView new];

[_MessagePopView setFrame:CGRectMake(0, 0, [UIScreen mainScreen].bounds.size.width, [UIScreen mainScreen].bounds.size.height)];

_MessagePopView.frame = CGRectMake(0, 0, SCREEN_WIDTH, SCREEN_HEIGHT);

[self.view addSubview:_MessagePopView];

[_MessagePopView showPopView];

}

效果图：



自己切不好图的话也可用UILabel代替~设置一下透明度就好
