看到标题你可能会觉得奇怪 推送消息提示框不是系统自己弹出来的吗？ 为什么还要自己自定义呢？
因为项目需求是这样的：最近需要做 远程推送通知 和一个客服系统 包括店铺客服和官方客服两个模块 如果有新的消息推送的时候 如果用户当前不在客服界面的时候 要求无论是在app前台 还是app退到后台 顶部都要弹出系统的那种消息提示框
这样的需求 我们就只能自定义一个在app内 弹出消息提示框
实现步骤如下：
1.我们自定义一个view 为 STPushView 推送消息的提示框view
#import <UIKit/UIKit.h>
#import "STPushModel.h"
@interface STPushView : UIView
/** *推送数据模型 */
@property(nonatomic,strong) STPushModel *model;
+(instancetype)shareInstance;
+ (void)show;
+ (void)hide;
@end
#import "STPushView.h"
#import "AppDelegate.h"
@interface STPushView()
@property (nonatomic, weak) UIImageView *imageV;
@property (nonatomic,weak ) UILabel *timLabel;
@property (nonatomic,weak ) UILabel *content;
@end
@implementation STPushView
static STPushView *_instance = nil;
+(instancetype)shareInstance
{
static dispatch_once_t onceToken;
dispatch_once(&onceToken, ^{
_instance = [[STPushView alloc] init];
});
return _instance;
}
+(instancetype) allocWithZone:(struct _NSZone *)zone
{
if (!_instance) {
_instance = [super allocWithZone:zone];
}
return _instance ;
}
- (instancetype)initWithFrame:(CGRect)frame
{

self.backgroundColor = CUSTOMCOLOR(15, 14, 12);

UIImageView *imageV = [[UIImageView alloc] init];
imageV.userInteractionEnabled = NO;
imageV.image = [UIImage imageNamed:@"logo"];
imageV.layer.cornerRadius = 5;
[self addSubview:imageV];
self.imageV = imageV;
[imageV mas_makeConstraints:^(MASConstraintMaker *make) {
make.left.equalTo(self).offset(margin);

}];
UILabel *titleLabel = [[UILabel alloc] init];
titleLabel.textColor = [UIColor whiteColor];

titleLabel.text = @"121店官方客服";
[self addSubview:titleLabel];
[titleLabel mas_makeConstraints:^(MASConstraintMaker *make) {
make.left.equalTo(imageV.mas_right).offset(margin);

make.height.mas_equalTo(16);
}];
[titleLabel sizeToFit];

[self addSubview:content];
self.content = content;
[content mas_makeConstraints:^(MASConstraintMaker *make) {
make.left.equalTo(imageV.mas_right).offset(margin);
make.top.equalTo(titleLabel.mas_bottom).offset(-3);
make.right.equalTo(self.mas_right).offset(-margin);
make.height.mas_equalTo(35);
}];
UIView *toolbar = [[UIView alloc] init];
toolbar.backgroundColor = CUSTOMCOLOR(121, 101, 81);
toolbar.layer.cornerRadius = 3;
[self addSubview:toolbar];
[toolbar mas_makeConstraints:^(MASConstraintMaker *make) {
make.width.mas_equalTo(35);
make.height.mas_equalTo(6);
make.centerX.equalTo(self.mas_centerX);

return self;

self.content.text = model.content;

pushView.hidden = NO;
