The Magic DIrk

上周末去东直门给孩子看中医，顺便带着他去三里屯苹果店玩玩，结果不让上二楼，我儿子最喜欢的儿童游戏 Math Blaster 只在楼上的 iMac 里才有，nnd，没玩成。

整个店都站满了黑衣黑裤的，还非常不友好，牛啊，简直是一个黑社会堂口，让我对苹果的印象大跌。

都是狗屁iPhone 4闹的。

熊啊！

Logging

In Xcode, click Run > Console to see NSLog statements.

NSLog(@"log: %@ ", myString);
NSLog(@"log: %f ", myFloat);
NSLog(@"log: %i ", myInt);

Display Images

Display an image anywhere on the screen, without using UI Builder. You can use this for other types of views as well.

CGRect myImageRect = CGRectMake(0.0f, 0.0f, 320.0f, 109.0f);
UIImageView *myImage = [[UIImageView alloc] initWithFrame:myImageRect];
[myImage setImage:[UIImage imageNamed:@"myImage.png"]];
myImage.opaque = YES; // explicitly opaque for performance
[self.view addSubview:myImage];
[myImage release];
