Theos iPhone Shell Command App

Question

I'm using theos to make a app for iOS that installs theos for those that don't know how.

Here is my code:

#import "RootViewController.h"
#import <UIKit/UIKit.h>

@implementation RootViewController
- (void)loadView {
    self.view = [[[UIView alloc] initWithFrame:[[UIScreen mainScreen] applicationFrame]] autorelease];
    self.view.backgroundColor = [UIColor blueColor];

    UIButton *installButton = [UIButton buttonWithType:UIButtonTypeRoundedRect];
    installButton.frame = CGRectMake(21, 80, 100, 35);
    [installButton setTitle:@"Install Theos" forState:UIControlStateNormal];
    [self.view addSubview.installButton];
    [installButton addTarget:self action:@Selector(installButtonPressed) forControlEvents:UIControlEventTouchUpInside];
    [self.view addSubview:installButton];
}

-(void)installButtonPressed
{
system("apt-get update");
system("apt-get install perl net.howett.theos");
}
@end

I keep getting this error when I go to make the package:

******-macbook:theosinstaller D3Ath$ make package

Can anyone help me fix it?

Answer 1

You've got two typos.

1.

[installButton setTitle:@"Install Theos" forState:UIControlStateNormal];
---> [self.view addSubview.installButton];
[installButton addTarget:self action:@Selector(installButtonPressed) forControlEvents:UIControlEventTouchUpInside];
[self.view addSubview:installButton];

There should be a colon instead of a period. I think you need to remove the line completely instead of just fixing it because you have the same exact line (but without a typo) later in the code.

2.

---> [installButton addTarget:self action:@Selector(installButtonPressed) forControlEvents:UIControlEventTouchUpInside];
[self.view addSubview:installButton];

Wrong case. It should be @selector, not @Selector
