XCode 5 - OpenURL無法在ViewController中工作

Question

在UIApplication Expecting ':'上獲取錯誤。

@interface ViewController() 

@end 

@implementation ViewController 

-(IBAction) pushButton{ 
    [[UIApplication sharedApplication openURL: [NSURL URLWithString:@"http://www.portfoliopathway.com"]]; 
} 

Answer 1

您錯過了sharedApplication後的右括號。

-(IBAction) pushButton{ 
    [[UIApplication sharedApplication] openURL:[NSURL URLWithString:@"http://www.portfoliopathway.com"]]; 
}
