iOS在状态栏上显示提醒信息的功能定制

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"];
