我正在使用以下代码将 Parse 对象更新为按钮操作:
-(IBAction)sendPressed:(id)sender
{
NSLog(@"boton subir cadena pulsado");
loadingSpinner.hidden = NO;
[loadingSpinner startAnimating];
//Upload a new picture
NSData *pictureData = UIImagePNGRepresentation(self.chainPhoto.image);
PFFile *file = [PFFile fileWithName:@"img" data:pictureData];
[file saveInBackgroundWithBlock:^(BOOL succeeded, NSError *error) {
if (succeeded){
NSLog(@"IMAGEN CARGADA");
PFQuery *query = [PFQuery queryWithClassName:@"cadenas"];
// Retrieve the object by id
[query getObjectInBackgroundWithId: chain.objectId block:^(PFObject *imageObject, NSError *error)
{
[imageObject setObject:file forKey:@"image"];
[imageObject setObject:self.commentTextField.text forKey:@"chain_name"];
[imageObject saveInBackgroundWithBlock:^(BOOL succeeded, NSError *error) {
if (succeeded){
//Go back to the wall
[self.navigationController popViewControllerAnimated:YES];
}
else{
NSString *errorString = [[error userInfo] objectForKey:@"error"];
[self showErrorView:errorString];
}
}];
}
ERROR HERE--> else
{
NSString *errorString = [[error userInfo] objectForKey:@"error"];
[self showErrorView:errorString];
}
}
[loadingSpinner stopAnimating];
//loadingSpinner.hidden = YES;
//self.commentTextField.text =@" ";
self.progress_block.hidden = YES;
// self.imageView.image = [UIImage imageNamed:@"no-image.jpg"];
UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"Restaurant Chain changed with success"
message:@"You can now go back to the list."
delegate:nil
cancelButtonTitle:@"OK"
otherButtonTitles:nil];
[alert show];
} progressBlock:^(int percentDone) {
self.progress_block.hidden =NO;
self.progress_block.progress = (float) percentDone/100+progressValue;
}];
}
我在代码中标记为 ERROR HERE 的行中，有一个错误警告(应为“:”)，但我找不到原因。
欢迎任何帮助。
最佳答案
从表面上看，您从未关闭查询括号:
PFQuery getObjectInBackground.... {
但从未使用正确的语法关闭它，或者看起来您有一个额外的括号 }。为了更好地练习，您应该在 if 语句中使用适当的缩进，否则可能会像这样发生复杂情况。你迷失在代码中，因为你不知道语句从哪里开始或结束
你应该在 else 语句之后关闭它:
} ERROR HERE--> else {
NSString *errorString = [[error userInfo] objectForKey:@"error"];
[self showErrorView:errorString];
//stop animating and other stuff
}
}];
我无法排除故障，因为我在使用 iPhone，但我建议返回并使用适当的缩进，这样您就可以捕获罪魁祸首
