I want to combine the array values into one string.
my arrays are like...
array1=[#"fizan",#"nike",#"pogo"];
array2=[#"round",#"rectangle",#"square"];
array3=[#"frame",#"frame",#"frame"];
I need like this...
value1 = fizan round frame
value2 = nike rectangle frame
value3 = pogo square frame
try this:
NSArray *array1= #[#"fizan",#"nike",#"pogo"];
NSArray *array2= #[#"round",#"rectangle",#"square"];
NSArray *array3= #[#"frame",#"frame",#"frame"];
NSMutableArray *array = [[NSMutableArray alloc] initWithArray:#[array1,array2,array3]];
NSMutableArray *output = [[NSMutableArray alloc] init];
NSString *a;
NSInteger count = array.count;
for (int i = 0; i<array1.count; i++) {
a = #"";
for (int j = 0; j<count; j++) {
a = [a isEqualToString: #""] ? [NSString stringWithFormat:#"%#",[[array objectAtIndex:j] objectAtIndex:i]] : [NSString stringWithFormat:#"%# %#",a,[[array objectAtIndex:j] objectAtIndex:i]];
}
[output addObject:a];
}
for (int i = 0; i < output.count; i++) {
NSLog(#"value %i -> %#",i+1,output[i]);
}
Hope this helps!
UPDATE:
NSArray *array1= #[#"fizan",#"",#"pogo"];
NSArray *array2= #[#"round",#"rectangle",#"square"];
NSArray *array3= #[#"frame",#"frame",#"frame"];
NSMutableArray *array = [[NSMutableArray alloc] initWithArray:#[array1,array2,array3]];
NSMutableArray *output = [[NSMutableArray alloc] init];
NSString *a;
NSInteger count = array.count;
for (int i = 0; i<array1.count; i++) {
a = #"";
for (int j = 0; j<count; j++) {
a = [a isEqualToString: #""] ? [NSString stringWithFormat:#"%#",[[array objectAtIndex:j] objectAtIndex:i]] : [NSString stringWithFormat:#"%# %#",a,[[array objectAtIndex:j] objectAtIndex:i]];
}
[output addObject:a];
}
for (int i = 0; i < output.count; i++) {
NSLog(#"value %i -> %#",i+1,output[i]);
}
I have tested this code. It works perfect. Check again and reconsider the issue.
Do this
NSArray *array1 = #[#"fizan", #"nike", #"pogo"];
NSString *value = [array1 componentsJoinedByString:#" "];
NSLog(#"value = %#", value);
Output will get like
value = fizan nike pogo
For your case
NSArray *completeArray = #[#[#"fizan",#"nike",#"pogo"], #[#"round",#"rectangle",#"square"], #[#"frame",#"frame",#"frame"]];
NSMutableArray *resultArray = [NSMutableArray array];
unsigned long count = 1;
for (int i = 0; i< count; i++) {
NSMutableArray *listArray = [NSMutableArray array];
for (NSArray *itemArray in completeArray) {
count = MAX(count,itemArray.count);
if (i < itemArray.count) {
[listArray addObject:itemArray[i]];
}
}
[resultArray addObject:listArray];
}
for (NSArray *itemArray in resultArray) {
NSString *value = [itemArray componentsJoinedByString:#" "];
NSLog(#"value = %#", value);
}
output
value = fizan round frame
value = nike rectangle frame
value = pogo square frame
Currently i'm using iosChart in my project. I have used the bar chart in shown below in image:

well, by default, ios-charts will calculate a modulus for x axis to decide the interval to draw the x axis labels. that's your case. because every label is longer than the bar, so to avoid the label overlap, we have to do it.
If you don't want so, just call xAxis.setLabelsToSkip(0)
If Label is overlap with each other then just add below code and see i think it's work.
[xAxis setLabelsToSkip:0];
[xAxis setWordWrapEnabled:YES];
I'm new to mac app development. I'm drawing a bar graph using core plot frame work.
What actually i want to is, when i select a month i want to draw graph for last 6 months.when i select '12/2012' I'm able to draw the graph correctly for last 6 months. But when i select '02/2013' the graph is showing only January and February and not the previous months.

Can Anyone Help me to solve the problem!!!
You need to update the xRange of the plot space. This will move the axis labels to the correct position and draw data points in the new range. You'll also need to add the new data points to the plot.
I get the "Value stored to 'myKeyArray' during its initialization is never read" message for the marked lines and i do not quite understand why this is happening.

I would take this line out, You shouldn't need to initialize it.
//NSArray *myKeyArray = [[NSArray alloc]init];
Change this to
NSArray *myKeyArray;
You only need to allocate it if it is mutable.
You're reassigning both myKeyArray and theObjects after you allocated memory for them, so you have a massive memory leak.
Remove the declarations with the allocations and move the variable declaration to the line where you perform the assignment:
NSArray *myKeyArray = [gameFileDict allKeys];
The same for theObjects:
NSArray *theObjects = [gameFileDict valueForKey:[myKeyArray objectAtIndex:oo]];
Note that you don't have to declare it as NSMutableArray. You're not changing the array.

I want to show custom labels on x-axis and default labels on y-axis.
EDIT:
I've tried adding sample class of barChart+XIB from CPTest-iPhoneApp. The bar chart appears but axis label's don't. Here is the screenshot form CPTest-iPhone app and mine.
CPXYAxis *yy = axisSet.yAxis;
yy.axisLineStyle.lineColor=[CPColor whiteColor];
yy.majorTickLineStyle = nil;
yy.minorTickLineStyle = nil;
yy.title = #"Y Axis";
yy.titleLocation = CPDecimalFromFloat(100.0f);
yy.titleOffset = 245.0f;
// Define some custom labels for the data elements
yy.labelingPolicy = CPAxisLabelingPolicyNone;
NSArray *customTickLocations1 = [NSArray arrayWithObjects:[NSDecimalNumber numberWithInt:0], [NSDecimalNumber numberWithInt:10],[NSDecimalNumber numberWithInt:20], [NSDecimalNumber numberWithInt:30], nil];
NSArray *yAxisLabels = [NSArray arrayWithObjects:#"a",#"b", #"c",nil];
NSUInteger labelLocation1 = 0;
NSMutableArray *customLabels1 = [NSMutableArray arrayWithCapacity:[yAxisLabels count]];
for (NSNumber *tickLocation1 in customTickLocations1)
{
CPAxisLabel *newLabel1 = [[CPAxisLabel alloc]
initWithText: [yAxisLabels objectAtIndex:labelLocation1++]
textStyle:yy.labelTextStyle];
newLabel1.tickLocation = [tickLocation1 decimalValue];
newLabel1.offset = yy.labelOffset + yy.majorTickLength;
[customLabels1 addObject:newLabel1];
[newLabel1 release];
}
yy.axisLabels = [NSSet setWithArray:customLabels1];
I have resolved my problem. All I have to do is start adding core-plot from beginning. I removed core-plot from my project again add voila! it's working
