receive memory warning but consumer fewer - ios

I'm doing a app like photo browser just like the "Photo" on iTOuch. And I use a third-party lib : https://github.com/kirbyt/KTPhotoBrowser
When I scroll the photos several times, the app crashes.
The log shows that it has receive memory warning.
Then I use instrument to check the memory (I choose Memory-Allocation).
I track the Live Bytes and Overall Bytes for "All Allocations".
However, the Live Bytes is never more than 5 MB, and the Overall Bytes is beyond 100 MB .
When the app carshes, the Live Bytes is 3.97MB and the Overall is 125.48MB.
I think Live Bytes is the memory currently used, and it seems it costs a little.
Why the app still crashes?
Xcode 4.2 4D199,Lion 10.7.2(11c74), iTouch ios5.0.1 beta2.
Below is the screenshot, and the instrument configuration is the default.
Any idea?
the crash log is like:

It is my own fault!
when I use NSURLConnection to detect the MIME-TYPE of the file, the memory of the connection is never released and it becomes larger and larger(As I detect the type of more than 100 files).
I reconstruct the code.

iOS app Crashes on Start Up

I developed an application with Xamarin studio. It runs completely fine with the iPhoneSimulator. I was able to run Ad-Hoc | Iphone and it compiles and actually saves the IPA directly to my phone. When I click the app it launches the load screen and crashes within 1 second.
I've tried to install command line tools for my OSX which is 10.9.
I'm all out of ideas, any help would be great.

Go through this, It' would be help you :
Architecture settings (armv6, armv7, armv7s) and also check your deployment version setting.
Set your Code Signing properly (Build Settings --> Code Signing)
Set/Check proper Deployment Target
Set/Check your Search Paths, if any. Check your other linker flags.
I think, might be possible your application run perfectly.

MFMailComposeViewController Crash because of large attachment

I'm using MFMailComposeViewController to send email.
But it crashed when sending large attachments, because of low-memory.
Does 'Mail' allocate memory for attachments?
And how should I do to

If your attachment data is the contents of a file on disk, the best you can do as the caller is create an NSData object from a mapped file:
NSData * attachmentData = [NSData dataWithContentsOfFile:myPath
options:NSDataReadingMappedIfSafe error:&error];
This transparently keeps the file on disk until parts of it are accessed, and allows the system to be as efficient as it can be.
But beyond that, if you run out of memory on the device, the attachment is too big. It's also fairly likely that the if the device runs out of memory trying to attach an email, the email service probably wouldn't accept the email message anyways it would be so large.
Mail doesn't have a limit, but an ISP would. A realistic limit for most people is probably 10MB, though you may want to keep it more around 5MB and split things across emails...
You can calculate the size of NSData using below code
NSData *pdfData=[NSData dataWithContentsOfFile:strpdfpath];
NSLog(#"PDFData Length is %.02fmb",(float)(int)[pdfData length]/1048576);
Then you can delete the file after successfully attached,
[[NSFileManager defaultManager] removeItemAtPath:[strpdfpath stringByDeletingLastPathComponent] error:&err];

Issue with iOS low memory crash but using very low memory - checked with instruments

I have a sample App that works fine on the simulator, but crashes on the device. I get the following output on the console from Organizer. It crashes within a short time.
Using instruments, memory leak, I see that the memory usage is about 2-3 mb. Using memory allocations, I see around 8-9mb for memory allocations and nothing in VM tracker.
The console output is given below. Can anyone kindly suggest what to do?

UIWebView strange behavior on different devices

I have developed a sample iPad application in which I open the one file of type ppt in UIWebView. When I run this application on iPad having O.S version 5.0(iPad2) & 4.3.1(iPad1) the application gets crash with following error(Memory Warning):

But when I run same application on iPad having O.S version 4.3.3(iPad2) it runs perfectly. What is the reason behind this strange behavior & any solution to solve this. Thanks in advance.
your app is crashing because it ran out of memory.
Try using PDF format or PPS (power point slide show) format. That may take some lesser space.

Simple application crashes

I have developed a simple app that calculates the risk of developing type 2 diabetes. The app runs fine from xcode on my iPhone 3Gs. I archived the app in a .ipa file and I have uploaded the app to my testflightapp.com account. I have installed the app on my iPhone with the standard testflightapp.com procedure: clicking the install link in the email from testflightapp.com.
When I run the app, I see the launch image for a few seconds and then it goes away. The console of my iPhone in xcode displays what is going wrong, but I do not know what this means:

Can anybody shine a light on this error?
On the iPhone, a process of a previous run of the application was still active. To fix the issue, all that is necessary is a reboot.
