主要的思路是调取高德地图的方法获取截图
前提是必须要加载地图，才能截图
1.加载截图
mapView = [[MAMapView alloc] initWithFrame:CGRectMake(0,64, YBScreenBoundsWidth, 250)];
mapView.showsUserLocation=YES;
//这是个app进入的时候定位获取的位置信息
CLLocationDegrees lat=[[[NSUserDefaults standardUserDefaults]valueForKey:@"lat"] doubleValue];
CLLocationDegrees longi=[[[NSUserDefaults standardUserDefaults]valueForKey:@"long"] doubleValue];
CLLocationCoordinate2D cllocation=CLLocationCoordinate2DMake(lat, longi);
mapView.centerCoordinate=cllocation;
mapView.zoomLevel=13;
///把地图添加至view
[self.view addSubview:mapView];
2.获取截图并上传
__block UIImage *screenshotImage = nil;
__block NSInteger resState = 0;
__block typeof(UIImage*) weekSnap = SnapshotImage;
[mapView takeSnapshotInRect:CGRectMake(0,64, YBScreenBoundsWidth, 250) withCompletionBlock:^(UIImage *resultImage, CGRect rect) {
SnapshotImage=resultImage;
CDLog(@"截图成功");
NSMutableArray *mdataArr=[[NSMutableArray alloc]initWithCapacity:0];
NSData *imageData = UIImageJPEGRepresentation(SnapshotImage, 0.5);
NSString *url=[[HJInterfaceManager sharedInstance]addRichInfo];
NSMutableDictionary *mdic=[[NSMutableDictionary alloc]initWithCapacity:0];
SelfDataModel *selfModel=[SelfDataModel returnModelBySelectFMDB];
// * @param familyId
// * @param userId
// * @param content
// * @param richContent
// * @param type
// * @param sendTime
NSDate *date=[NSDate date];
NSDateFormatter *form=[[NSDateFormatter alloc]init];
[form setDateFormat:@"YYYY-MM-dd HH:mm:ss"];
NSString *datestr=[form stringFromDate:date ];
if (!self.isMyself) {
[mdic setObject:self.family.idNum forKey:@"familyId"];
}
[mdic setObject:selfModel.idNum forKey:@"userId"];
[mdic setObject:@"" forKey:@"content"];
[mdic setObject:[NSString stringWithFormat:@"%lf,%lf",
[[[NSUserDefaults standardUserDefaults]valueForKey:@"lat"] doubleValue],[[[NSUserDefaults standardUserDefaults]valueForKey:@"long"] doubleValue]] forKey:@"location"];
[mdic setObject:[imageData base64Encoding] forKey:@"richContents"];
[mdic setObject:self.type forKey:@"type"];
[mdic setObject:datestr forKey:@"sendTime"];
[HJHttpManager PostRequestWithUrl:url param:mdic finish:^(NSData *data) {
NSDictionary *dic=(NSDictionary *)data;
if ([dic[@"status"] isEqualToString:@"S"]) {
[MBProgressHUD hideHUD];
[MBProgressHUD showSuccess:@"发送成功"];
dispatch_after(dispatch_time(DISPATCH_TIME_NOW, (int64_t)(2 * NSEC_PER_SEC)), dispatch_get_main_queue(), ^{
[self.navigationController popViewControllerAnimated:YES];
});
}else{
[MBProgressHUD hideHUD];
[MBProgressHUD showError:dic[@"message"]];
}
} failed:^(NSError *error) {
[MBProgressHUD hideHUD];
[MBProgressHUD showError:@"请求失败"];
NSLog(@"请求失败");
}];
}];
