从自己开发的软件跳转到系统短信界面，并且把内容和图片给显示在信息中
在调用系统的短信控件时需要先导入<MessageUI/MessageUI.h>
同时需要遵循代理方法
@interface ViewController ()<MFMessageComposeViewControllerDelegate>
@property (nonatomic, strong) UITextField * photoText;
@property (nonatomic, strong) UITextField * messageText;
@property (nonatomic, strong) UIImage * imageCache;
@property (nonatomic, strong) NSString * urlStr;
@end
系统控件MFMessageComposeViewController 方法的实现
这个方法可以把本地文件添加到彩信中，网络图片需要先加载到本地保存，然后添加过后再删除
- (void)sendPicBtnClick:(UIButton *)sendPic {
if ([MFMessageComposeViewController canSendAttachments]) {
MFMessageComposeViewController * messageVC = [[MFMessageComposeViewController alloc]init];
messageVC.recipients = @[self.photoText.text];
messageVC.body = self.messageText.text;
//本地图片
// NSString *path = [[NSBundle mainBundle] pathForResource:@"rainy" ofType:@"jpg"];
// if ([messageVC addAttachmentURL:[NSURL fileURLWithPath:path] withAlternateFilename:nil])
// {
// NSLog(@"添加成功");
// }else{
// NSLog(@"失败");
// }
//网络图片
// NSData * imageData = UIImageJPEGRepresentation(_imageCache, 1.0);
NSString * documentsDirectoryPath = [NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES) objectAtIndex:0];
NSString * path = [documentsDirectoryPath stringByAppendingPathComponent:@"MyImage.png"];
if ([messageVC addAttachmentURL:[NSURL fileURLWithPath:path] withAlternateFilename:nil])
{
NSLog(@"添加成功");
}else{
NSLog(@"失败");
}
// NSData * imageData = UIImagePNGRepresentation(_imageCache);
// if ([messageVC addAttachmentData:imageData typeIdentifier:@"png" filename:@""]) {
// NSLog(@"添加成功");
// }else{
// NSLog(@"添加失败");
// }
messageVC.messageComposeDelegate = self;
/** 取消按钮的颜色(附带,可不写) */
messageVC.navigationBar.tintColor = [UIColor redColor];
[self presentViewController:messageVC animated:YES completion:nil];
}else{
NSLog(@"模拟器不支持发送短信");
}
}
代理方法的实现
- (void)messageComposeViewController:(MFMessageComposeViewController *)controller didFinishWithResult:(MessageComposeResult)result
{
/** 发送完信息就回到原程序*/
[self dismissViewControllerAnimated:YES completion:nil];
switch (result) {
case MessageComposeResultSent:
NSLog(@"发送成功");
break;
case MessageComposeResultFailed:
NSLog(@"发送失败");
break;
case MessageComposeResultCancelled:
NSLog(@"发送取消");
default:
break;
}
}
