iOS 6 & iOS 7 的适配笔记

iOS 6 & iOS 7 的适配

场景1: 没有NavigationController,同时根视图是UIView
- (void)viewWillLayoutSubviews

if ([[UIDevice currentDevice].systemVersion floatValue] >= 7.0) {
NSLog(@"======> %f", [self.topLayoutGuide length]);
CGFloat top = [self.topLayoutGuide length];

// 直接修改self.view的bounds属性
CGRect bounds = self.view.bounds;
// 强行往下挤20个点,其它不变
bounds.origin.y = -top;
self.view.bounds = bounds;
}

可以抽成宏

#define kIOS7_NONav_View \

- (void)viewWillLayoutSubviews\

{\

if ([[UIDevice currentDevice].systemVersion floatValue] >= 7.0) {\

NSLog(@"======> %f", [self.topLayoutGuide length]);\

CGFloat top = [self.topLayoutGuide length];\

CGRect bounds = self.view.bounds;\

bounds.origin.y = -top;\

self.view.bounds = bounds;\

}\

}

场景2: 没有NavigationController,同时根视图是UIScrollView/UITableView
- (void)viewDidLoad
{
[super viewDidLoad];

// 根视图是一个UITableView,继承自UIScrollView
// contentInset属性可以设置滚动视图距离边界的距离
if ([[UIDevice currentDevice].systemVersion floatValue] >= 7.0) {
[self.tableView setContentInset:UIEdgeInsetsMake(20, 0, 0, 0)];
}
}

场景3: 有NavigationController,同时根视图是UIView

if ([[UIDevice currentDevice].systemVersion floatValue] >= 7.0) {
[self setEdgesForExtendedLayout:UIRectEdgeNone];
}

场景4: 有NavigationController,同时根视图是UIScrollView/UITableView

不需要任何处理!
