iOS7 各种问题解决

1 UITableView 行分割线不到头，短线问题

if ([self.tableView respondsToSelector:@selector(setSeparatorInset:)]) {

[self.tableView setSeparatorInset:UIEdgeInsetsZero];

}

2 iOS 7 全屏幕排版 改为 iOS 6 的排版方式。默认从状态栏和导航栏下面开始排版

- (void)viewDidLoad

{

if ([self respondsToSelector:@selector(edgesForExtendedLayout)]) {

self.edgesForExtendedLayout = UIRectEdgeNone;

}

[super viewDidLoad];

// Do any additional setup after loading the view.

}

3 UIActionSheet 少了一条分割线的问题

原始代码

UIActionSheet *actionSheet = [[UIActionSheet
alloc]

initWithTitle:@"Title"

delegate:self

cancelButtonTitle:nil

destructiveButtonTitle:nil

otherButtonTitles:@"First", @"Second",
@"Third", @"Fourth",
nil];

[actionSheet showInView:self.view];

可以设置cancelButtonTitle 或手动加入一个cancelButton

UIActionSheet *asAccounts =
[[UIActionSheet alloc]
initWithTitle:Localized(@"select_an_account")

delegate:self

cancelButtonTitle:nil

destructiveButtonTitle:nil

otherButtonTitles: nil];

for (int
i=0; i<[result count]; i++) {

ACAccount *acct = [result objectAtIndex:i];

[asAccounts addButtonWithTitle:[acct username]];

asAccounts.tag = i;

}

[asAccounts
addButtonWithTitle:Localized(@"Cancel")];

asAccounts.cancelButtonIndex = result.count;

[asAccounts showInView:self.view];

4 iOS7 中UISegmentedControl的背景色是透明的。如果要加入背景色

没有找到属性，替代方法是加入一个圆角的UIView。

引用#import
<QuartzCore/QuartzCore.h>

CGRect
vRect = UISegmentedControl.frame;

vRect.size.width--;
