Question

I m 只是学习可可(来自C#)和Im ,对似乎很简单的东西留下了奇怪的错误。 (charsSince Last Update >= 36

#import "CSMainController.h"

@implementation CSMainController
//global vars
int *charsSinceLastUpdate = 0;
NSString *myString = @"Hello world";
//

- (void)applicationDidFinishLaunching:(NSNotification *)aNotification {
...
}

//other functions
- (void)textDidChange:(NSNotification *)aNotification {
    NSLog(@"charsSinceLastUpdate=%i",charsSinceLastUpdate);
    if (charsSinceLastUpdate>=36) { // <- THIS line returns the error: Comparison between pointer and integer
        charsSinceLastUpdate=0;
        [statusText setStringValue:@"Will save now!"];
    } else {
        charsSinceLastUpdate++;
        [statusText setStringValue:@"Not saving"];
    }

}

//my functions
- (void)showNetworkErrorAlert:(BOOL)showContinueWithoutSavingOption {
...
}
//

@end

感谢大家的任何帮助。

在您的法典中,charsSince LastUpdate 是pointer,你需要将其定义为而没有。 www.un.org/Depts/DGACM/index_french.htm

<0>t charsSince LastUpdate = 0;

当然,除非你meant将其定义为指点人,在这种情况下,你需要使用devis营运人。 • 收回它所指明的价值,如:

if(*charsSinceLastUpdate >= 36) {
   //...
}
