想了解iOS在状态栏上显示提醒信息的功能定制的相关内容吗，踏歌寻方在本文为您仔细讲解iOS状态栏上显示提醒信息的相关知识和一些Code实例，欢迎阅读和指正，我们先划重点：ios状态栏,ios,显示状态栏,ios,显示提示信息，下面大家一起来学习吧。

先看效果图

实现这个效果，用到了JDStatusBarNotification，这是一个易于使用和定制的在状态栏上显示提醒信息的控件，可自定义颜色、字体以及动画，支持进度条展示，并可以显示活动指示器。

假设这么一个场景，需要调接口修改个人资料，这时有3个状态，正在修改、修改成功、修改失败。我们可以写一个公共类，方便调用，譬如 NSObject+Common。

.h文件写方法

#import <Foundation/Foundation.h>

@interface NSObject (Common)

- (void)showStatusBarQueryStr:(NSString *)tipStr;
- (void)showStatusBarSuccessStr:(NSString *)tipStr;
//此方法在实际开发中调用，调接口失败返回的error
- (void)showStatusBarError:(NSError *)error;
//...
- (void)showStatusBarErrorStr:(NSString *)tipStr;

@end

.m文件实现方法

#import "NSObject+Common.h"
#import "JDStatusBarNotification.h"

@implementation NSObject (Common)

//error返回的tipStr
- (NSString *)tipFromError:(NSError *)error {
 if (error && error.userInfo) {
  NSMutableString *tipStr = [[NSMutableString alloc] init];
  if ([error.userInfo objectForKey:@"msg"]) {
   NSArray *msgArray = [[error.userInfo objectForKey:@"msg"] allValues];
   NSUInteger num = [msgArray count];
   for (int i = 0; i < num; i++) {
    NSString *msgStr = [msgArray objectAtIndex:i];
    if (i+1 < num) {
     [tipStr appendString:[NSString stringWithFormat:@"%@\n", msgStr]];
    }else{
     [tipStr appendString:msgStr];
    }
   }
  }else{
   if ([error.userInfo objectForKey:@"NSLocalizedDescription"]) {
    tipStr = [error.userInfo objectForKey:@"NSLocalizedDescription"];
   }else{
    [tipStr appendFormat:@"ErrorCode%ld", (long)error.code];
   }
  }
  return tipStr;
 }
 return nil;
}

- (void)showStatusBarQueryStr:(NSString *)tipStr {
 [JDStatusBarNotification showWithStatus:tipStr styleName:JDStatusBarStyleSuccess];
 [JDStatusBarNotification showActivityIndicator:YES indicatorStyle:UIActivityIndicatorViewStyleWhite];
}

- (void)showStatusBarSuccessStr:(NSString *)tipStr {
 if ([JDStatusBarNotification isVisible]) {
  dispatch_after(dispatch_time(DISPATCH_TIME_NOW, (int64_t)(0.5 * NSEC_PER_SEC)), dispatch_get_main_queue(), ^{
   [JDStatusBarNotification showActivityIndicator:NO indicatorStyle:UIActivityIndicatorViewStyleWhite];
   [JDStatusBarNotification showWithStatus:tipStr dismissAfter:1.5 styleName:JDStatusBarStyleSuccess];
  });
 }else{
  [JDStatusBarNotification showActivityIndicator:NO indicatorStyle:UIActivityIndicatorViewStyleWhite];
  [JDStatusBarNotification showWithStatus:tipStr dismissAfter:1.0 styleName:JDStatusBarStyleSuccess];
 }
}

- (void)showStatusBarError:(NSError *)error {
 if ([JDStatusBarNotification isVisible]) {
  dispatch_after(dispatch_time(DISPATCH_TIME_NOW, (int64_t)(0.5 * NSEC_PER_SEC)), dispatch_get_main_queue(), ^{
   [JDStatusBarNotification showActivityIndicator:NO indicatorStyle:UIActivityIndicatorViewStyleWhite];
   [JDStatusBarNotification showWithStatus:[self tipFromError:error] dismissAfter:1.5 styleName:JDStatusBarStyleError];
  });
 }else{
  [JDStatusBarNotification showActivityIndicator:NO indicatorStyle:UIActivityIndicatorViewStyleWhite];
  [JDStatusBarNotification showWithStatus:[self tipFromError:error] dismissAfter:1.5 styleName:JDStatusBarStyleError];
 }
}

- (void)showStatusBarErrorStr:(NSString *)tipStr {
 if ([JDStatusBarNotification isVisible]) {
  dispatch_after(dispatch_time(DISPATCH_TIME_NOW, (int64_t)(0.5 * NSEC_PER_SEC)), dispatch_get_main_queue(), ^{
   [JDStatusBarNotification showActivityIndicator:NO indicatorStyle:UIActivityIndicatorViewStyleWhite];
   [JDStatusBarNotification showWithStatus:tipStr dismissAfter:1.5 styleName:JDStatusBarStyleError];
  });
 }else{
  [JDStatusBarNotification showActivityIndicator:NO indicatorStyle:UIActivityIndicatorViewStyleWhite];
  [JDStatusBarNotification showWithStatus:tipStr dismissAfter:1.5 styleName:JDStatusBarStyleError];
 }
}

调用方法

[self showStatusBarQueryStr:@"正在修改个人信息"];

[self showStatusBarSuccessStr:@"个人信息修改成功"];

//[self showStatusBarError:error];
[self showStatusBarErrorStr:@"修改失败"];
