How do I build the following view?
I want to build a form using a standard UITableViewController, but I need to have an image that spans the first two rows. Rows have text in them (not pictured).
One way I've considered is to have the Image and first two rows actually be one row with another UITableView embedded inside it, with scrolling disabled.
But I'd really like to do something with indenting.
UITableView
+-----+---------------+
| | | <---+ Row 0
UIImageView +---> | +---------------+
| | | <---+ Row 1
+-----+---------------+
| | <---+ Row 2
+---------------------+
| |
+---------------------+
| |
+---------------------+
| |
+----------------
|
+-----------
|
+------
| Etc..
+--
|
How can I accomplish this, using the fewest widgets / least amount of code (for iOS 4+)?
You've probably realized this isn't standard, so I think your three options are:
Two images that fit to look like one.
rows 1 & 2 are actually 1 row that looks like it's two rows.
row 1 has an image as big as the first two rows, and subview clipping is off so it overlays row two.
I'd be inclined to use option #1, but if the images will change or be dynamic, I might go for option #2
I ended up putting a UIImageView and a nested UITableView inside the row 0 UITableViewCell. The nested UITableView has scrolling disabled and provides one group with two rows. Then I just had to fudge the frame a bit.
I think your best bet would be to subclass UITableViewCell for your first 2 cells. You should be able to lay it out to look like 1 big cell or your rowspanned cells, then just use the default for all the remaining cells.

I have two tables. In first table, each row represents a polygon. In second table, each row represents a point. I want to find if each point within one of the polygon. I try to use ST_Contains, ST_MultiPolygon, and ST_Point in hive. I think there is a way to feed all rows into ST_MultiPolygon, but not sure how to do that. The following is my test data.
pid | shape
1 | [2,0,3,0,3,1,2,1]
2 | [0,0,1,0,1,1,0,1]
This is Polygon table.
pid | x | y
1 | 0.5 | 0.5
2 | 2.1 | 0.5
3 | 1.5 | 0.5
This is Point table
I want to get the result like
pid | is_in
1 | true
2 | true
3 | false
Here is the way I think to solve this problem. what I wanna do is to determine if a point is in one of the Polygon that is stored in hive. Suppose I have 2 polygons [2,0,3,0,3,1,2,1] and [0,0,1,0,1,1,0,1], actually they really are [(2,0), (3,0), (3,1), (2,1)] and [(0,0), (1,0), (1,1), (0,1)]. The reason that I stored in this odd way is because ST_MultiPolygon takes this kind of format as a parameter, like ST_MultiPolygon(array(2,0,3,0,3,1,2,1)). Combined ST_MultiPolygon with ST_Contains and st_point, I can get a boolean result that indicates if a point is in a MultiPolygon. ST_MultiPolygon can even takes multiple arrays, such as ST_MultiPolygon(array(2,0,3,0,3,1,2,1), array(0,0,1,0,1,1,0,1)). By this way, if there is a way for me to feed all Polygons into MultiPolygons, then I know if a point in one of the Polygon.
Any comment will be appreciated.
Consider the following data:
Item | Overall | Individual | newColumn
A | Fail | Pass | blank
A | Fail | Fail | blank
B | Fail | Pass | issue
B | Fail | Pass | issue
C | Pass | Pass | blank
I have the logic built out for the first 3 columns already. There are two levels of fails in this data:
overall, and
individual.
If any of the individual fail, the overall fails. Sometimes the overall can fail even though all the individuals are fine. This logic is already built out.
I am trying to find a formula for the newColumn. If all the individuals are a pass for a given item (example item B), but the overall is still a fail, the cell should return the text "issue". It is ok if it returns issue twice, not sure if you can non-dupe that part. I've tried various forms of countifs/and/ors and creating columns that count distinct values but I always find a scenario where it will break the logic.
Try this:
=IF(COUNTIFS($A$2:$A$6,A2,$C$2:$C$6,"Fail"),"blank",IF(B2="Fail","Issue","blank"))
As required
If you add a new column with the formula:
=IF(B2="Fail",IF(COUNTIFS(A:A,A2,C:C,"fail")=0,"issue",""),"")
Then this should work on the assumptions:
For each item if one of the overalls are false they are all false
The only two possible values are "Pass" and "Fail" for columns B & C
If you require the word blank instead of a blank cell then use:
=IF(B2="Fail",IF(COUNTIFS(A:A,A2,C:C,"fail")=0,"issue","blank"),"blank")
Hi I'm quite new in Pentaho Spoon and I have a problem:
I have a table like this:
model | type | color| q
--1---| --1-- | blue | 1
--1---| --2-- | blue | 2
--1---| --1-- | red | 1
--1---| --2-- | red | 3
--2---| --1-- | blue | 4
--2---| --2-- | blue | 5
And I would like to create a single table (to export in csv or excel) for each model grouped by type with the value of the group as header and as value the q value:
table-1.csv
type | blue | red
--1--| -1-- | -1-
--2--| -2-- | -3-
table-2.csv
type | blue
--1--| -4-
--2--| -5-
I tried with row denormalizer but nothing.
Any suggestion?
Typically it's helpful to see what you have done in order to offer help, but I know how counterintuitive the "help" on this step is.
Make sure you sort the rows on Model and Type before sending them to the denormalizer step. Then give this a try:
As for splitting the output into files, there are a few ways to handle that. Take a look at the Switch/Case step using the Model field.
Also, if you haven't found them already, take a look at the sample files that come with the PDI download. They should be in ...pdi-ce-6.1.0.1-196\data-integration\samples. They can be more helpful than the online documentation sometimes.
Row denormalizer can't be used here if number of colors is unknown, also, you can't define text output fields dynamically.
There are few ways that I can see without using java and js steps. One of them is based on the following idea: we can prepare rows with two columns:
Row Model
type|blue|red 1
1|1|1 1
2|2|3 1
type|blue 2
1|4 2
2|5 2
Then we can prepare filename for each row using Model field and then easily output all rows using text output where file name is taken from filename field. In this case all records will be exported into two files without additional efforts.
Here you can find sample transformation: copy-paste me into new transformation
Please note that it's a sample solution that works only with csv. Also it works only if you have the same number of colors for each type inside model. It's just a hint how to use spoon, it's not a complete solution.
I have the variable labels and value labels in a table in my database, like this
id_variable_label | variable_label | id_value_label | value_label | id_father_label
---------------------------------------------------------------------------------------------------------
1 | father_label | null | null | null
null | father_label | 1 | child01 | 1
null | father_label | 2 | child02 | 1
Is there a way to generate automatically all the variables and value labels when I import the data from my database through a ODBC connection?
There isn't a direct way to do this, but if you read that table as an SPSS dataset, it would be pretty simple to generate the labels with a little Python code.
Note also that if your labeling is static, you can use APPLY DICTIONARY to copy labels from one dataset to another, so saving one fully labeled file would allow you to propagate that to others that are similarly structured.
You can use SPSS syntax to create variable and value labels.
See the SPSS commands VARIABLE LABELS and VALUE LABELS.
Here's a tutorial here that explains how you can use them.
You could generate the syntax from your database.
I have crosstab which has row columns indicating different classes, and then peoples names across the top.
| | Required | Person 1 | Person 2 | Person 3 |
| Class 1 | 8 6 | 1 6 | 3 6 | 4 6 |
| Class 2 | 6 2 | 3 2 | 2 2 | 1 2 |
Each field contains 2 values The first value is the number of hours spent in the class, the second field is the number of hours required for certification.
The Required field id my grand total summary.
In the cross tab expert the fields are defined as follows.
Rows:
Command.descr -> a field containing the class names
Columns:
Command.fullname -> a field containing students full names
Summarized Fields:
Sum of Command.evlength -> summation of all time spent in a given course
Max of #required -> this formula returns the number of required hours based on the course name
I am trying to highlight the field Sum of Command.evlength if it is greater than or equal to the value of Max of #required.
My solution was to perform background formatting. Right-Click on the Sum of Command.evlength field, select Format Field. Click the borders tab, check Background, and enter a formula.
The formula I was using is:
if CurrentFieldValue >= {#required} then color(152, 251, 152) else crNoColor
This is not the correct formula. My crosstab has been placed in the footer, which causes {#required} to contain the last value in the grid which in the above example is 2.
From my research I thought I would have to use GridRowColumnValue(row or column name) to access the value of {#required} in the crosstab, but I could not come up with the correct string to represent it.
Does anyone have a way for me to correctly perform this comparison?
Frustratingly I don't think you can use the highlighting expert to compare to a dynamic value. You could swap the columns round then add the following formulas:
To the max_of_required background colour:
whileprintingrecords;
global numbervar required_hrs := currentfieldvalue;
crNoColor;
To the sum_of_command.evlength background colour:
whileprintingrecords;
global numbervar required_hrs;
if currentfieldvalue >= required_hrs then
crRed
else
crNoColor;
I think there are a few other ways but i'm not as confident with those so start here.
