UIImageView初始化

大多数时候我们使用uiimage时候用

[UIImage imageNamed:@"xxxx.png"];

但是这样会创建一个自动释放池,一般用路径来初始化uiimage


UIImage *image=[[UIImage alloc] initWithContentsOfFile:[[[NSBundle mainBundle] bundlePath] stringByAppendingPathComponent:@"xxx.png"]];

UIImageView *imageView = [[UIImageView alloc] initWithImage:image];

[self.view insertSubview:imageView atIndex:0];

[image release];
