Iphone彈出提醒消息

Question

我無法在任何地方找到它。我不想每次都使用調試器。如何在iPhone上獲取打印消息。

Answer 1

使用的NSLog功能：

NSLog(@"Your message here."); 
// with parameters: 
NSString * myParam = @"Some value"; 
NSLog(@"myParam:%@", myParam); 

這些消息被寫入到控制檯日誌。您可以在模擬器上運行Console.app或通過切換到的XCode調試器/控制檯視圖(XCode -> Run -> Console)

查看他們，如果你真的想做一個彈出警報（如JavaScript的alert()功能），你可以這樣做：

UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"Test Message" 
                message:@"This is a sample" 
               delegate:nil 
             cancelButtonTitle:@"OK" 
             otherButtonTitles:nil]; 
[alert show]; 
[alert release]; 

Answer 2

使用Google或Xcode文檔查看器查找UIAlertView。

Answer 3

UIAlertView* alert; 
alert = [[UIAlertView alloc] initWithTitle:@"Info" message:@"Much more info" delegate:nil cancelButtonTitle:@"OK" otherButtonTitles: nil]; 
[alert show]; 
[alert release]; 

Answer 4

// open a alert with an OK and cancel button 
UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"UIAlertView" 
     message:@"My message" delegate:self cancelButtonTitle:@"Cancel" 
     otherButtonTitles:@"OK", nil]; 
[alert show]; 
[alert release];
