I have a map image in svg wants to display it on the screen so user can zoom in zoom out can touch on some specific points & I'll show up some popups.
Anyone have idea that how can I achieve this I'm also attaching a png photo of that map.
Any help will be highly appreciated.
You can achieve this by using the satellite view of google maps editing in the image is apparently is not possible
I followed the above tutorial (link) to make a sample app which will show markers depending upon the location coordinates for the objects(like a building) .I'm able to show my custom markers on the given location .But markers are floating around the location.How can fix my marker to show on the top of the building .?
Any suggestion or advice...
Thanks in advance!!!!!!
Your problem is most likely due to sensor jitter. Gyroscopes usually don't provide an stable reading.
I suggest you do a rolling average of the values and also add thresholds for minimum variation.
Is there any way to show only the pure map in ios? Without any text, label or annotation.
Sample iOS Map
For ex, in that picture there is a lot of texts, labels..
Somehow... From iOS7 you can provide your own tiles, but you lose map kit original tiles.
Mattt has written an interesting post on NSHipster, you should check it
Another option is to try the Mapbox tools to allow full map customization.
I have been looking all around the net for open source graph plot framework for iOS, but I am struggling with it as of now. I have worked on an app and used PowerPlot Graph Plot framework http://powerplot.nua-schroers.de/examples/webtraffic.html
I am trying to draw a bar graph chart showing two years at once without stacking each, like in the image below: As you can see there is a problem of resizeing and the scaling isnt uniform. I would like to make the chart look bigger and the y axis be more formatted.
Any suggestions because I always hear about core plot also by which you can achieve such(see below), but all i hear about coreplot is flexibility and customization issues.
You can easily produce a bar plot like that with Core Plot. Give it a try and ask specific questions here on StackOverflow if you get stuck.
I have two sets of array containing 7 objects, with values in one and dates on another.
I would like to generate a simple bar graph with date on x axis and values on y axis.
I searched google and ofcourse stackoverflow, but I didn't find a satisfactory answer.
In every answer, it's all about Coreplot, which I don't want to use because of it's complexity(Me being a begineer in ios development).
Is there any other way except, CorePlot to achieve such graph? Or Can someone provide me an example to plot using inbuilt apple API'S
Awaiting an answer, Thanks a lot in advance.
You will need to do this inside a custom UIView.
In the drawRect method you can calculate the extent of the x-axis and the y-axis. You then need to draw the axes onto the actual screen with the numbers showing the values.
Then you need to work out how thick each bar should be and how tall they need to be.
Then draw them into their relevant spaces along the x-axis.
Before any of this though you need to give is a background colour. Maybe some guide lines so the user can easily read the values...
Or you can use http://www.cocoapods.org to install CorePlot and it will do it all for you.
It is MUCH MUCH MUCH MUCH more difficult to draw the graph yourself than it is sto spend a while learning how to use coreplot.
I tried using coreplot, but it is a giant framework which is too good and toodifficult for a begineer like me to consume. So I came across OVGraph, which is a basic framework that does all I want, And it is easy to use as well,
something like this :
OVGraphView *graphview=[[OVGraphView alloc]initWithFrame:CGRectMake(0, 0, 480, 300) ContentSize:CGSizeMake(960, 300)];
//customizations go here
[self.view addSubview:graphview];
[graphview setPoints:#[[[OVGraphViewPoint alloc]initWithXLabel:#"today" YValue:#3.2 ],[[OVGraphViewPoint alloc]initWithXLabel:#"yesterday" YValue:#4 ],[[OVGraphViewPoint alloc]initWithXLabel:#"3" YValue:#6 ]]];
generates beautiful graphs.
Another option can be EChart which has EColumnChart
This third party project worked nice for me and I found the design much better than most other projects. Unfortunately is paid, but it's always an option :)
