By User



I want to send sms using below code in iPhone 4, but the application is crashing due to this code only.







if ([MFMessageComposeViewController canSendText]) {

                MFMessageComposeViewController *smsComposerController = [[[MFMessageComposeViewController alloc] init] autorelease];

                [smsComposerController setBody:@"First SMS"];

                smsComposerController.recipients = [NSArray arrayWithObjects:@"9886333333",@"9980444444",nil];

                smsComposerController.messageComposeDelegate = self;

                [smsComposerController release];

            }







I am new for SMS sending , so can any one help me what I am doing wrong?

    You need to add [self presentModalViewController:smsComposerController animated:YES];
    in your code to send the sms.

    if ([MFMessageComposeViewController canSendText]) {
    MFMessageComposeViewController *smsComposerController = [[[MFMessageComposeViewController alloc] init] autorelease];
    [smsComposerController setBody:@"First SMS"];
    smsComposerController.recipients = [NSArray arrayWithObjects:@"9886333333",@"9980444444",nil];
    smsComposerController.messageComposeDelegate = self;
    [self presentModalViewController:smsComposerController animated:YES];
    }

    You're autoreleasing and then releasing again smsComposerController.

    Just release it once. You can review you memory management rules here.

    if ([MFMessageComposeViewController canSendText]) {
    MFMessageComposeViewController *smsComposerController = [[[MFMessageComposeViewController alloc] init] autorelease];
    [smsComposerController setBody:@"First SMS"];
    smsComposerController.recipients = [NSArray arrayWithObjects:@"9886333333",@"9980444444",nil];
    smsComposerController.messageComposeDelegate = self;
    [smsComposerController release]; <-------------- THIS IS YOUR ERROR
    }


    You should not release an auto-release object.

Slow Android emulator

By User
I have a 2.67 GHz Celeron processor, 1.21 GB of RAM on a x86 Windows XP Professional machine. My understanding is that the Android emulator should start fairly quickly on such a machine, but for me it does not. I have followed all instructions in setting up the IDE, SDKs, JDKs and such and have had some success in staring the emulator quickly but is very particulary. How can I, if possible, fix this problem?
